    A new species in Coprinus subsection Setulosi (2002)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 18 no. 1, pp. 143-145
    Details
    Publication Date: 2024-03-06
    Description: Coprinus canistri spec. nov. is proposed. It belongs to the subsection Setulosi because of the presence of pileo- and caulocystidia. A comparison is given with C. subimpatiens and C. congregatus, on account of similar microscopical characters.

    Genetic and ecological differentiation between the butterfly sisterspecies Colias alfacariensis and Colias hyale (2002)
    In:  Contributions to Zoology vol. 71 no. 4, pp. 131-139
    Details
    Publication Date: 2024-02-22
    Description: Clear habitat separation between the sister species Colias alfacariensis and C. hyale is shown when occurring sympatrically. Colias hyale is found more often in moist cultivated pastures while Colias alfacariensis is more abundant in dry uncultivated habitat. Out of a total of 16 loci, no diagnostic loci were found between C. alfacariensis and C. hyale, and both species shared most major polymorphisms. Exceptions were the marked differences in allele frequencies at the HK locus and only C, hyale, but not C. alfacariensis was further invariable at the GOT2 locus, which is usually highly polymorphic in the Pieridae. Colias hyale has a significantly lower level of heterozygosity than its sister species C. alfacariensis. In Colias alfacariensis heterozygosity is highest in the Alps and lowest in the low-lying region of Northern France, Both species show high levels of gene flow over a large geographic area. Within C. alfacariensis, but not in C. hyale, the FST value of the PGI locus is significantly different from zero effectively separating the species into populations with high levels of the \xe2\x80\x99 b\xe2\x80\x99 allele to the west and North, and low levels of the allele in the Alps and Italy. This could point to selection within the PGI locus in line with the well established pattern of selection at the PGI locus in other species of Colias. Glaciations have been an important force in shaping the evolutionary history of European biota, leading to extinction, but also allowing new species to evolve into the newly available land as the ice sheets retreated. The genetic and distributional pattern found between both Colias species suggests that habitat shifts and subsequent adaptation during glaciations could have played an important role in their speciation.

    A new Xanthophyllum (Polygalaceae) from Borneo (1970)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 18 no. 2, pp. 392-392
    Details
    Publication Date: 2024-02-08
    Description: In his paper on the peat swamp forests of Sarawak and Brunei (Gard. Bull. 20, 1963, 152) Dr. J. A. R. Anderson made notice of a distinctive Xanthophyllum species which he was not able to identify. In 1968, Mr. F. S. P. Ng, revising the genus for the Manual of Malayan Timber Trees, recognized it as a new species, but did not describe it. Working now on a monograph of the genus, and having examined all collections Dr. Anderson kindly sent on loan to me, I am able to describe it here as a new species.\nI am much indebted to Dr. H. Sleumer for rendering the diagnosis in Latin.

    Biosystematic notes on Atriplex patula L., A. hastata L., and A. littoralis L. (Chenopodiaceae) (1970)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 18 no. 1, pp. 53-63
    Details
    Publication Date: 2024-02-08
    Description: In about 10\xe2\x80\x9415 % of the cases a sharp distinction between Atriplex hastata L., patula L., littoralis L., and glabriuscula Edm. is not possible, both in the field and in the herbarium. In order to establish the status of the \xe2\x80\x98intermediates\xe2\x80\x99 a karyological examination was undertaken of 95 samples collected in the Netherlands including both typical specimens and intermediates. It appeared that the specimens clearly representing A. hastata, littoralis, or glabriuscula are diploid (n = 9), but those representing A. patula tetraploid (n = 18). The \xe2\x80\x98intermediates\xe2\x80\x99 between A. hastata and patula are either diploid or tetraploid. Hence a sharp distinction between the latter two taxa is only possible on the chromosome number. A similar result was found for the \xe2\x80\x98intermediates\xe2\x80\x99 between A. patula and littoralis. It depends on the specific concept one adheres to whether these four taxa should be ranked as species; European botanists usually give them specific rank, their American colleagues infraspecific rank. Autogamy seems to be the rule in these species. This as well as the chromosome numbers found rule out the possibility of hybridization as an explanation for the occurrence of intermediates. I have strong doubts as to the artificial hybrids reported in literature because of the technical difficulties involved and apparently not solved. Special attention has been paid to possible characters to be derived from the leaves, the phyllotaxis, and the bracts. The variation in the leaves of the four species examined is overlapping. The same holds true for the phyllotaxis and the ripe fruits and fruiting bracteoles. An account is given of some abnormalities which have been found during the chromosome countings. An attempt was made to correlate morphological characters of the leaf, especially the leaf-base and leaf-index, and the chromosomes in A. hastata and patula. The results presented in the scatter diagrams show that, though on the whole there is a marked correlation between leafshape and chromosome number, no sharp distinction can be made. Finally a provisional key is given.

    Details
    Publication Date: 2024-02-08
    Description: Three new adventitious species of Amaranthaceae are recorded for the Netherlands: Gomphrena celosioides Mart., Alternanthera ficoidea (L.) R. Br. ex Grisebach var. bettzickiana (Regel) Backer and an unidentified species of Alternanthera. Of the latter a description is given and the identification is requested. Gomphrena and Alternanthera can be separated as follows: 1. Stigma capitate or shortly ................... 2-lobed Alternanthera 1\xe2\x80\x99. Stigma branches 2, filiform to subulate ................... Gomphrena Gomphrena globosa and G. celosioides are easily recognized by the dorsal crest of the bracteoles. The species of Alternanthera here described can be fitted in the key given by VAN OOSTSTROOM & REICHGELT (1961) in the following manner: 0. Anthers lanceolate to linear; pseudostaminodes ligular with laciniate apex. 00. Bracts and bracteoles ca. \xc2\xbe times as long as the tepals. Outer tepals with 3\xe2\x80\x945 thick nerves at base. Pseudostaminodia \xc2\xb1 as long as the stamens. A. ficoidea var. bettzickiana 00\xe2\x80\x99. Bracts and bracteoles longer than the tepals. Outer tepals at most faintly nerved. Pseudostaminodia shorter than the stamens .................. A. spec. 0\xe2\x80\x99. Anthers ellipsoid; pseudostaminodia narrowly triangular to linear-subulate, entire. 1. Tepals etc.

    Three new species of Entoloma from Kerala State, India (2002)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 17 no. 4, pp. 625-630
    Details
    Publication Date: 2024-02-01
    Description: Three new species of Entoloma s.l. from Kerala State, India are described, illustrated and discussed. Entoloma haematinum, a very small, bright red, omphalinoid species, reminiscent of Hygrocybe cantharellus, is unique because of its quadrate-cuboid spores; it fits well in subgenus Omphaliopsis. Entoloma nubilum and E. carneum are both characterised by their small, pleurotoid basidiocarps. The first is related to the species of subgenus Leptonia; the second fits better in subgenus Claudopus. Comments are given on the taxonomic position of the new species.

    Zur Wasserversorgung der Microchiropteren Eptesicus zuluensis vansoni (Vespertilionidae) und Sauromys petrophilus erongensis (Molossidae) in der Namibw\xc3\xbcste (1970)
    In:  Bijdragen tot de dierkunde vol. 40 no. 1, pp. 71-73
    Details
    Publication Date: 2024-01-12
    Description: On the central Kuiseb in the southern Namib insectovorous bats are to be found at an important density. The following species could be approved: Eptesicus hottentotus pallidior (Vespertilionidae), Eptesicus zuluensis vansoni (Vespertilionidae), Sauromys petrophilus erongensis (Molossidae) and Nycteris thebaica damarensis (Nycteridae).\nUnder the extreme climatic conditions the microchiroptera find prey enough, at least during the summer months, because this dry river-bed with its trees that partially are compact like a forest, offers favourable conditions of development to insects (above all to Coleoptera, Lepidoptera and Hymenoptera). It is being examined in which way these desert bats provide for their need of water in a region where we hardly find open water places during a large period of year. Feeding experiments have shown that Eptesicus zuluensis vansoni and Sauromys petrophilus erongensis can do without having water for several months if they find enough insects. During the observation period a female of E. zuluensis vansoni gave birth to twins, one young of which was nourished up to the end of the lactation period.

    Le baculum de Tadarida teniotis (1970)
    In:  Bijdragen tot de dierkunde vol. 40 no. 1, pp. 8-9

    Publication Date: 2024-01-12
    Description: Depuis quelques d\xc3\xa9cennies, les mammalogistes en g\xc3\xa9n\xc3\xa9ral et les chiropt\xc3\xa9rologues en particulier ont d\xc3\xa9couvert que l\xe2\x80\x99\xc3\xa9tude du baculum (= os p\xc3\xa9nien) pouvait constituer un caract\xc3\xa8re syst\xc3\xa9matique, au niveau de la famille, du genre et de l\xe2\x80\x99esp\xc3\xa8ce, et apporter une contribution non n\xc3\xa9gligeable \xc3\xa0 la connaissance des relations interg\xc3\xa9n\xc3\xa9riques et intersp\xc3\xa9cifiques. Il suffira de citer, pour la faune pal\xc3\xa9arctique, les deux esp\xc3\xa8ces de Plecotus qui, par l\xe2\x80\x99\xc3\xa9tude de leur os p\xc3\xa9nien, peuvent \xc3\xaatre identifi\xc3\xa9s presque \xc3\xa0 coup s\xc3\xbbr, alors que la morphologie g\xc3\xa9n\xc3\xa9rale est tr\xc3\xa8s semblable et qu\xe2\x80\x99il \xc3\xa9tait tr\xc3\xa8s difficile de les distinguer par les caract\xc3\xa8res classiques habituels: mensuration (et indices), morphologie g\xc3\xa9n\xc3\xa9rale, du cr\xc3\xa2ne, de la dentition, coloration, etc. Il en va de m\xc3\xaame pour les Myotis myotis et Myotis blythi (oxygnathus).\nEn ce qui concerne les Molossid\xc3\xa9s, la seule esp\xc3\xa8ce europeenne, Tadarida teniotis, n\xe2\x80\x99avait pas fait l\xe2\x80\x99objet de recherches tr\xc3\xa8s pouss\xc3\xa9es. Il faut dire que Kuzjakin (1950: 418) avait d\xc3\xa9courag\xc3\xa9 les curieux en affirmant \xe2\x80\x9cos penien non pr\xc3\xa9sent\xe2\x80\x9d. Plus r\xc3\xa9cemment, Lanza (1959: 11-12) \xc3\xa9crit qu\xe2\x80\x99il n\xe2\x80\x99a pas encore de donn\xc3\xa9es suffisantes pour cette esp\xc3\xa8ce, mais que le molosse de Cestoni \xe2\x80\x9cest pourvu d\xe2\x80\x99un miniscule os p\xc3\xa9nien, de moins de 1 mm, situ\xc3\xa9 \xc3\xa0 la pointe du p\xc3\xa9nis et, semble-t-il, de forme assez variable\xe2\x80\x9d.
