    Description: Neohattoria Kamim. is a monotypic genus of the Jubulaceae (= Frullaniaceae) with a single species, N. herzogii (Hatt.) Kamim., known from central to northern Japan and the southern part of the Kurile Islands. The present genus was segregated from Frullania by Kamimura (1961; sub. nom. Hattoria Kamim. nom. illeg., non Schust., 1961) on the basis of the branching type, the shape of the first leaf and underleaf on branch, the total lack of secondary pigmentation, the uniform cell structure of the stem in cross section, and the strongly toothed leaf lobes. The generic concept of Neohattoria was greatly expanded by Schuster (1970), who included eight species and classified them into two subgenera, subgen. Neohattoria (with a single species) and subgen. Microfrullania Schust. (with seven species); however, Hattori et al. (1972) transferred all species of subgen. Microfrullania to a newly segregated genus Schusterella Hatt. et al., thus retaining the monotypic status of Neohattoria. As already described and illustrated by Hattori (1955), Kamimura (1961), Mizutani (1961), Ladyzhenskaja (1963), Schuster (1970), and Hattori et al. (1972), Neohattoria herzogii is closely related to species of both Jubula and Frullania. Regarding the taxonomic desposition of Neohattoria, Mizutani (1961) and Mizutani & Hattori (1969) placed it with Jubula in a subfamily Jubuloideae of Lejeuneaceae and Hattori et al. placed it in Jubulaceae (s. lat.). But, Kamimura (1961), Schuster (1970, 1979), and Guercke (1978) placed it more close to Frullania, e.g. in a subfamily Frullanioideae of Jubulaceae (s. lat.); more recently, Asakawa et al. (1979b), admitting three distinct families, Jubulaceae, Frullaniaceae, and Lejeuneaceae, placed Neohattoria and Jubula in the Jubulaceae (s. str.) but Frullania and Schusterella in the Frullaniaceae.

    Description: The six species of Curtia, including a hitherto undescribed species published here, as well as the monotypic genus Hockinia can be distinguished from each other by the seed coat structure. The anticlinal walls and the cuticle provide the most useful information. Curtia tenuifolia appears to be a complex species, but subsp. tenella can be readily separated from this complex by the seed coat structure. Heterostyly has been found in C. tenuifolia subsp. tenuifolia, C. obtusifolia, and Hockinia montana, but differences in seed coat structure can not be correlated with long-, short-, and equal-styled flowers. The differences in seed coat structure, the length of the seeds, and the number of cells per seed plead for maintaining Hockinia (closely related to Curtia) as a distinct genus. One new species of Curtia is described and a new combination is made.

    Description: SETTEN, A. K. van & KOEK-NOORMAN, J.: Studies in Annonaceae. VI. A leafanatomical survey of genera of Annonaceae in the Neotropics. — Bot. Jahrb. Syst. 108: 17—50. 1986. — ISSN 0006-8152. Within the scope of the multidisciplinary research project on systematics of Annonaceae, a survey of the leafanatomical features and their distribution in the neotropical Annonaceae is presented. The studied specimens form a rather homogeneous group, as may appear from the family description given here. A detailed study of the leafanatomical features reveals, that differences are mainly found in the indument, the position and contents of the idioblasts, the structure of the primary vein, the type of crystals in the epidermal cells, and the type of sclereids. Based on character states, phenetic similarities and differences are discussed and compared with the classifications of FRIES (1959) and WALKER (1971).

    Description: Recently a multidisciplinary investigation program on the systematics of Annonaceae was started at Utrecht with special emphasis on the Neotropics. This project will be carried out largely within the framework of the UNESCO-project Flora Neotronica. The first goal is to provide a modern classification of the family as a whole, the second is the publication of a series of monographs for Flora Neotropica. The project has been planned and started in close consultation with leading botanists on the Neotropical flora. The Annonaceae are a family of pantropical distribution with between 2000 and 2500 species in ca. 130 genera as presently understood. In the Neotropics the family is represented by ca. 750 species and 35 genera. It is a family of trees, shrubs, and lianas. Its place is within the order of the Magnoliales and its supposedly closest relative is the family of the Myristicaceae. The Annonaceae, although generally considered primitive in many features, nevertheless offer a number of specialized features as well This makes it a promising object using various kinds of comparative morphological, karyological, and anatomical data. Besides, many species are of medicinal or commercial value, such as various species of Annona and Rollinia, the fruits of which are commonly eaten in most countries of Central America and South America; the Soursop (Annona muricata) is widely cultivated throughout the tropics.

    Description: The originally monotypic eastern Malaysian genus Schiffneriolejeunea Verdoorn 1933 has now become a widespread, pantropical group of about fifteen species by the inclusion of species from the genus Ptychocoleus Trev. nom. illeg. Six species are known from Asia, three of which constitute the sect. Saccatae (Verdoorn) Gradst. & Terken comb. nov. These are the widespread Schiffneriolejeunea tumida (Nees) Gradst., the eastern Malaysian S. cumingiana (Mont.) Gradst. and S. nymannii (Steph.) Gradst. & Terken comb. nov. Schiffneriolejeunea tumida is a rather polymorphic species in which two not sharply defined varieties may be distinguished: S. tumida var. tumida with more or less involuted leaf margins, and S. tumida var. haskarliana (Gott.) Gradst. & Terken comb. nov. with plane margins.

    Description: A phytosociological survey based on methods of the Zürich-Montpellier School was carried out in the páramo vegetation of the Cordillera Oriental, Colombia. The study area covers about 10,000 and comprises the páramo between the Nevado de Sumapaz (3°55'N, 4250 m), the Sierra Nevada del Cocuy (6°25'N, 5493 m) and the Páramo del Almorzadero (7°N, 4375 m). The páramo vegetation was studied along various altitudinal transects from the upper forest line (3000-3500 m) up to the lower limit of the snowcap (4800 m). A general description of the study area includes data on geology, geomorphology, soils, climate, flora, phytogeography, morphological characters of the vegetation, fauna and landuse. The evolution and Quaternary history of páramo vegetation and climate is reviewed, incorporating the first data from the Lateglacial and Holocene of the Páramo de Sumapaz. The general altitudinal zonation of the páramo vegetation was studied and is presented for both the dry and the humid side of the Cordillera. The zonal and azonal plant communities are described including their physiognomy, composition and syntaxonomy, habitat and distribution. Eighty five syntaxa from the rank of variant to that of the class are newly described, 17 of which are provisional. The vegetation is not ranked syntaxonomically yet, but described on the basis of preliminary tables. A number of azonal communities, part of them of lesser extent, are described in a similar way. The páramo vegetation is primarily determined by the tropical diurnal high mountain climate. The diversity of the páramo vegetation is related to temperature (altitudinal gradient) and to humidity (dry and wet climate). The presence of zonal bunchgrass páramo, bamboo-bunchgrass páramo or bamboo páramo mainly depends on the complex interrelation between these factors. Finally a synthesis is provided on ecology, morphology and phytogeography of the páramo vegetation of the study area.

    Description: Isoëtes Palmeri with a distribution in the High Andes from the Páramo of Venezuela to the Páramo of Ecuador is described as a new taxon, and dedicated to the then American specialist of the genus, Thomas Chalkley Palmer (1860-1934). The new species belongs to the tropical-Andeanaustral-antarctic section Laeves, described as new here as well. The publication of the new species had to be anticipated to the projected monographic treatment of the South-American representatives of the genus Isoëtes, as A.M. Cleef, Utrecht intends to base a new association, the Isoëtetum Palmeri on this new taxon, observed and collected by him at many instances within the Colombian Páramo between 1971 and 1980 in the context of the preparation of his doctoral thesis now under way.

    Description: In his introductory statements to 'The Symposium on the Phylogeny and Classification of the Filicopsida' which was held in London, 1972, HOLTTUM, when dealing with 'dubious groups of relationships which would particularly repay investigation', mentioned the Polypodiaceae first (HOLTTUM, 1973: 6). Talking about Polypodiaceae the present authors deal with the Polypodiaceae sensu stricto only, thus excluding the Cheiropleuriaceae, Dipteridaceae, Grammitidaceae, and also the Loxogrammaceae, taxa which were formerly (or are still) included in the Polypodiaceae sensu lato. As delineated in this way, this almost exclusively pantropical family consists of about 600 species and an indefinite number of genera.

    Description: Until recently relatively little attention has been paid to the study of chromosomes in liverworts. The first substantial contributions were made by Heitz (1927, 1928) and Lorbeer (1934). In the second half of this century chromosome studies on liverworts were mainly carried out in Europe (e.g. Fritsch 1972; Newton 1977, 1979) and Japan (e.g. Tatuno 1959; Segawa 1965a, b, c; Inoue 1968). Inoue (in Koponen 1979) reports that until now 28% of all bryophyte species in Japan have been investigated as to their chromosome complement. A comprehensive, but rather outdated, survey of chromosome numbers in Hepaticae and Anthocerotae was given by Berrie (1960). Work on a new, updated survey is now underway (Fritsch, in prep.). In the present article results are presented of a cytotaxonomic investigation of European species of the genera Aneura and Riccardia (Aneuraceae). Most specimens were gathered in the Netherlands, but some chromosome counts based on French and German plants are also included.

    Description: IUCN, says the paper Categories, Objectives and Criteria for Protected Areas, ”is dedicated to the wise use of the Earth’s natural resources and to the maintenance of the Planet’s natural diversity.” What to think of the sequence? Use first, maintain second? And this comes from the International Union for the Conservation of Nature and Natural Resources? ”The World National Parks Congress, taking place in Bali, Indonesia, October 11-22, 1982, will provide case studies from around the world to illustrate how the various categories of protected areas are meeting the needs of countries of all economic, social, cultural, and political backgrounds,” writes J.A. McNeely, the secretary of the Commission on National Parks and Protected Areas, in a special issue of the Swedish journal Ambio (11: 237. 1982). ”No longer just playgrounds for vacationers and means for conserving natural heritage, protected areas have become an inseparable part of the modern human ecosystem.”

    Description: Tropical Botany in Aberdeen University. This was started by Professor J.W.H. Trail, who held the chair from 1877 to 1919, and travelled in the Amazon Valley (1873-75) mainly collecting cryptogams and studying palms. He was succeeded by Prof. W.G. Craib (1920-33) who was never in the tropics but devoted his work to the Flora of Siam, based on the collections of A.F.G. Kerr, and assisted by Miss E.C. Barnett. After a considerable lag, tropical botany was revived by the energetic efforts of Dr. P. Ashton as lecturer in systematics and ecology of the eastern tropics, establishing ties with Malayan colleges in teaching and research. This is at present perpetuated by two lecturers, Dr. K. Jong and Dr. M.D. Swaine, the latter’s experience lying largely in the tropics of West Africa. In addition Dr. N.M. Pritchard, Dr. J.B. Kenworthy and Dr. G. Hadley have been on secondment to the University of Malaya, while Dr. I. Alexander made research visits to India, Ghana and Peru. Over the years the Department has provided undergraduate and research training to innumerable students from many different tropical countries, some of which attained responsible posts, e.g. Prof. E. Soepadmo. Important courses in tropical biology are given, not available elsewhere in the U.K. (started 1973). The benefits for Aberdeen students is important: amongst others they led to expeditions to various parts of the tropics, recently to Sabah and to the Ivory Coast. Royal Society Tropical Rain Forest Collaborative Research Programme. Arising out of a feasibility study by Dr. T.C. Whitmore and P.F. Cockburn, the theme ’Recovery of tropical rain forest after disturbance’ was adopted as the initial basis of the programme. Possible territories for the research include Sabah and the Philippines. Detailed plans for a 5-year project are being prepared in consultation with colleagues in Southeast Asia.

    Publication Date: 2015-04-20
    Description: It is with the utmost regret that we announce the sudden and quite unexpected death of Dr. Marius Jacobs, editor of this Bulletin. See the obituary on page 3869. He was co-editor of the Flora Malesiana Bulletin for nr. 17 (1962) to nr. 22 (1968) and took full responsibility onwards of nr. 27 (1974). He showed great ability in enlarging its scope and we have many letters in our archives expressing appreciation and admiration for the lively and informative style in which he edited the Bulletin. I had to take over the editorial work for this number at short notice, but I was greatly helped by a number of Rijksherbarium colleagues, which help is gratefully acknowledged. In this way the delay has been kept to a minimum. It is, however, possible that some news items etc. have not been printed and that information submitted to Dr. Jacobs has not been entered due to this sudden change of editorship. I offer my apologies if this has happened and hope that (if still relevant) the news will again be forwarded to the new editor, Dr. J.F. Veldkamp, Rijksherbarium, who will take over starting next number.

    Description: Among the collections of Knema acquired by the Rijksherbarium since the publication of my new account of the genus Knema, in Blumea 25, 1979: 321 — 478, a few specimens caused problems with the identification, and at closer examination these yielded facts of interest which are published here. Some specimens represented stages not yet known, for instance fruits, or male flowers, while other specimens meant a significant range extension of the species. Two new species and one new subspecies are described. For easy reference, the sequence and numbers of the species presently treated correspond with the numbers as used in the account of 1979. The new species bear the number of the species after which they appear in the general key of 1979, with the addition ‘-bis’.

    Description: The early development (ontogeny) of the carpels of 20 species belonging to 8 apocarpous families was investigated with the scanning electron microscope. The results indicate that on the floral apex a circular or a convex meristem develops into an obliquely ascidiate primordium by unequal growth of its periphery. By further unequal growth it develops into a young carpel. The terminal mouth of a cup becomes the lateral cleft of a carpel. The different forms of the young carpels in different species are defined by the varying degree of development of the adaxial region of the initial meristem and/or its margin on the side of the floral apex. This hypothesis is theoretically evaluated.

    Description: In Malesia the genus Tephrosia is represented by 20 species, native or introduced and naturalized, including 6 subspecies and 5 varieties; 4 species are restricted to Malesia. Two of these species are newly described: T. barbatala and T. elliptica; the former includes one new variety (var. glabra). Two new subspecies and one new variety are distinguished: T. filipes subsp. longifolia, T. purpurea subsp. barbigera, and T. maculata var. elongata. Two taxa are given a new status: T. maculata var. appressepilosa and T. pumila subsp. aldabrensis. Four species, T. dichotoma, T. repentina, T. coarctata, and Kiesera sumatrana are for the first time sunk into synonymy. A key to the taxa, synonymy, and full descriptions with plates and distribution maps are given.

In the course of a revision of this family for the Flora Malesiana, some new species of both genera have been found. Eight new ones of Thottea were published in a precursor on that genus (Blumea 27, 1981, 301-332, f. 1-72). There are four new species of Aristolochia from Borneo and one more new Thottea from Sumatra to be described here.

    Description: Carpels develop centripetally as oblique slightly ascidiform structures provided with a seat-like support. The terminal mouth of the ascidiform primordium becomes the lateral cleft of the carpel. Solitary terminal carpels develop as lateral structures. The sections Tasmannia and Drimys of the genus Drimys differ by the varying degree of ascidiform development. Austrobaileya is like Drimys. The structure of the carpel margins with submarginal placentation may have evolved from a slit like that in Winteraceae. Allometric development of an oblique ascidiform structure may have formed a large basal ovary, and may thus have moved the stigmatic part apically. A possible cupular origin of carpels is discussed.

    Description: Owing to their limited possibilities for either active or passive dispersal, their association with the soil habitat, their vulnerability towards a dry atmosphere, and, in fact, on account of their general ecology and ethology, Diplopoda among arthropods are surely one of the most important classes in relation to the study of historical biogeography. For the class as a whole the sea appears to be an unsuperable barrier as is proved by the almost complete absence of endemic taxa on oceanic islands. In many cases lowland plains also act as severe obstacles against the dispersal of millipedes. The presence or absence of diplopods on islands or continents, therefore, may give a strong argument in favour or against any supposed former land connection. The long geographical isolation of the Australian continent and the absence of endemic higher taxa seems to imply that most, if not all, of its diplopod fauna dates from the time this continent was solidly attached to other southern continents, i.e. the Mesozoic. Subsequent penetration of fauna elements from the north or northwest seems utterly unlikely, although perhaps not entirely impossible.

    Description: The buthid scorpions of the genus Centruroides are widely distributed in the Antillean area. They are also the most common scorpions in the majority of these islands. Nevertheless they remained almost forgotten until recently (STAHNKE 1970; ARMAS 1976, 1977, 1980, 1981, 1982; FRANCKE & SISSOM 1980). For the purpose of this paper the Lesser Antilles are defined as the islands situated between the Virgin Islands and Trinidad & Tobago, according to BOND’S 1978 zoogeographical point of view.

    Description: The formation of thick piles of flysch-like sediments needs the existence of narrowed seas, active denouement of neighbouring continents, and generalized marginal subsidence. These conditions are present during the initial and final stages of Wilson’s perceptive cycle. In this context, the Late Precambrian flysch of the Iberian Massif must be related to the initial rifting, whilst the Culm of southwestern Iberia was accumulated during an episode of Upper Palaeozoic subduction that remained active after the impingement of Iberia against North America. Culm sediments shed from the uplifted collision zone and fed into a remnant ocean that remained at the nonsutured southern border of Iberia. This model of synorogenic flysch formation has been described elsewhere for similar plate arrangements. On other grounds this model provides a framework that explains the different structural and magmatic trends of the Ossa-Morena Zone (near the active margin) in the context of the rest of the Massif (basement reactivation). In addition to this, it seems to support a partly primary origin for the Iberian arc versus a secondary origin.

    Description: During the Late Devonian, deposition in the Cantabrian Mountains was largely controlled by movements along faults. By way of intermitting subsidence of the area south of the Sabero-Gordón line and the connected progradation of the coast during the Frasnian and early Famennian, three regressive sequences were deposited. On account of these sequences the Nocedo Formation is divided into three units. Before the late Famennian transgression, after which the upper part of the Ermita Formation was deposited, the area was peneplained. Six facies maps show the changes in palaeogeography during the Late Devonian.

    Description: The area described comprises the SE plunging extension of the anticlinorium of Mondoñedo-Lugo-Sarria and several structural units to the NE of it. The stratigraphy compares with that of neighbouring areas. Certain new observations have been made regarding the west flank of the East Galician-West Asturian miogeosyncline at the end of the Precambrium and during the Early Palaeozoic. Stromatolites or algae played an important part in the formation of carbonate deposits during late Precambrian (Cándana limestone) and Lower Cambrian time (Vegadeo limestone). An imprint, possibly attributable to a specimen belonging to the Precambrian Ediacara fauna, was found in the Cándana Schist Formation. A shallow or relatively high zone existed during that time in the region around Incio. The same general area formed a high again at the end of the Ordovician, causing erosion and a marked disconformity of the Silurian. The Hercynian structures can be explained by assuming roughly WSW-ENE compression and shortening. In the NW of the area this is expressed in the first place by the recumbent folds of the Lugo-Sarria anticlinorium, and in the SE by the narrowness of the steep folds and their slightly changed direction in the general area of Seoane and El Cebrero. Normal crossfaults are related to the folding and the compression. They show locally a deviation in accordance with the direction of shear stress. Horizontal displacement along such faults in an EW direction was probably of little importance. Finally a few observations are given on the occurrence of Pb-Zn ores at the mine of Rubiales.

    Description: Species of the heteropod families Carinariidae and Pterotracheidae collected in the Mid North Atlantic Ocean in 1980 have been studied. The distribution of the species is given, as well as the morphological variation. It is concluded that two subspecies of Carinaria lamarcki actually have to be considered distinctly recognisable and sympatric species, to be called C. lamarcki and C. challengeri. The vertical distribution of the heteropods studied proves not to be restricted to the photic zone and diurnal vertical migration occurs among the larger species. The horizontal distribution of the two Carinaria species and of at least two populations of the Pterotrachea species coincides with the southern branch of the North Atlantic Current, while others are restricted to the subtropical waters. Consequently, the present heteropods have to be considered good indicators of water masses and currents.

    Description: Moult cycle and morphogenesis in larval instars (zoea I, zoea II, megalopa) of the spider crab Hyas araneus were studied in the laboratory. Changes in the epidermis and cuticle were documented photographically at daily intervals to characterize the stages of the moult cycle. Stage A (early postmoult) is a very short period during which the larva takes up water. During late postmoult (B) and intermoult (C) the endocuticle is secreted, and there is conspicuous epidermal tissue condensation and growth. The onset of early premoult (D sub(0)) is characterized by epidermal apolysis, occurring first at the bases of the setae in the telson of zoeal instars or in the rostrum of the megalopa.

    Description: Larvae of the crabs Menippe mercenaria Say (Menippidae), Panopeus herbstii Milne-Edwards, Neopanope sayi Smith (Xanthidae), Sesarma cinereum Bosc (Grapsidae), and Libinia emerginata Leach (Majidae) were reared in the laboratory. Starvation periods different in length and timing within the first zoeal stage were studied as to their effects on later development and survival rate. After 1-3 days of initial feeding, most larvae had accumulated enough reserves to reach the second stage, independently of further food availability. The development of the survivors was delayed in the following stages, and their later mortality rate was higher than the fed controls. Starvation periods commencing directly after hatching of the larvae exert far stronger negative effects than those beginning later. All observations suggest a particularly sensitive phase in the beginning of larval life in brachyurans. When initial starvation periods exceed the point-of-no-return (PNR), the larvae will die later, even if feeding begins long before the energy reserves are depleted. Temporary lack of suitable prey may be an ecological factor controlling the survival of crab larvae as effectively as physical factors.

    Description: Resistance to starvation in early larval stages of six species of brachyuran crabs representing four families was observed at various constant temperatures. In the optimal temperature range of 25-30°C for these warm temperate crab larvae, survival time of starved zoeae was longer than the development duration time in fed zoeae, while at lower temperatures the relationship of these two duration periods became inversed. This response pattern is found in larvae of the mud crab Rhithropanopeus harrisii and is considered to be typical for warm temperature brachyuran larvae. It indicates that reserved utilization is strongly controlled by temperature, but not to the same degree as development.

    Description: Larval and early post-larval growth has been investigated in H. araneus L. (Majidae) reared in the laboratory. Growth was measured as dry weight (DW), ash-free dry weight (AFDW), carbon (C), nitrogen (N), hydrogen (H), gross biochemical constituents (protein, lipid, carbohydrate, chitin, ash) and energy (calculated separately from carbon and biochemical composition). During larval development, i.e. from freshly hatched zoea-I to late megalopa, all these criteria of biomass increase by factors ranging between 5 and 14; carbohydrate shows the lowest, chitin the highest increment. There are indications of loss in organic body weight during the latest period preceding metamorphosis to the crab stage. When no food is offered during this time, megalopae lose significantly more biomass than control larvae. This suggests that food is still required, but feeding activity is reduced to a level below maintenance ingestion rate. Following metamorphosis, the juvenile crab accumulates biomass at a far higher absolute rate (expressed as µg/d) than all larval stages.

    Description: The development of hard bottom communities has been studied on test panels in Helgoland Harbour (German Bight) since 1977. Settlement and growth of epibenthic species was examined monthly. Natural variation in different seasons, years, and at three stations (the latter, only in 1981 and 1982) was investigated. At Station A (Binnenhafen), barnacles (Balanus crenatus ) and polychaetes (Polydora ciliata ) were always among the first settlers in spring. They were followed by other barnacles (Elminius modestus, Balanus improvisus ) and by colonical ascidians (Botryllus schlosseri ). The latter species often dominated from August to October, and tended to overgrow the barnacle populations.

    Description: The larval development f the spider crab Hyas araneus L. was studied in the laboratory at different constant temperatures (2,6,12, and 18 °C). Linear relationships between log temperature and log stage duration were described by means of regression equations. They were used in a simple simulation model predicting larval moulting and metamorphosis at different temperatures. The most important predictions were : (1) Settlement of H. araneus takes place mainly from late May to mid-June; (2) assuming wide annual fluctuations in the average spring temperature ( plus or minus 2 °C), a total settlement period ranging from late April to early July can be expected; (3) delay of larval development due to a decrease in temperature is stronger than the acceleration caused by an equally great increase; and (4) both delay and acceleration effects become weaker during the hatching season and from stage to stage.

    Description: Zoea-1 larvae of H. araneus were kept under different nutritional conditions. Their midgut glands were investigated with a transmission electron microscope. The glandular epithelium consists of the cell types known from adult decapods. It is mainly the R-cell type that undergoes ultrastructural alterations which reflect nutritional conditions. R-cells of fed larvae are characterized by large lipid inclusions; after a certain period of food deprivation (point-of-no-return) the original ultrastructure cannot be reestablished. Refeeding results in large glycogen deposits in these cells.

    Description: Early diagenetic ultrastructural alterations of benthic foraminifers of the genera Elphidium and Ophtalmina from the shallow water sediments of the Kiel Bight were investigated by scanning electron microscopy. Pure solution patterns were deduced from supplementary experiments.Several carbonate destroying processes can be specified by ultrastructural patterns of the shell surfaces. Based on these patterns three zones are established, each showing different mechanisms of shell fragmentation: 1) zone of abrasion, 2) zone of disintegration, 3) zone of corrosion. This zonation depends on the water depth and is caused primarily by water agitation and by undersaturation of the bottom water with respect to carbonate.
