    Description / Table of Contents: Forensic geoscience is an increasingly important sub-discipline within geoscience and forensic science. Although minerals, soils, dusts and rock fragments have been used as only begun to be recognized in the last ten years or so. The police and other investigative bodies are keen to encourage such developments in the fight against crime, particularly since many criminals show a high level of forensic awareness with regard to evidence such as fingerprints, blood and other body fluids. The papers in this volume illustrate some of the main principles, techniques and applications in current forensic geoscience, covering research and casework in the UK and internationally. The techniques described range from macro-scale field geophysical investigations to micro-scale laboratory studies of the chemical and textural properties of individual particles. In addition to forensic applications, many of these techniques have broad utility in geological, geomorphological, soil science and archaeological research.

    Notes: Abstract When 20 newly hatched larvae either of Metaseiulus occidentalis (Nesbitt), Neoseiulus fallacis (Garman), Amblyseius andersoni Chant or Typhlodromus pyri Scheuten were held in arenas without food at 95% RH and 20°C, the percentages of mites surviving to protonymphs were 5.0, 81.3, 86.3, and 83.8%, respectively. Unfed M. occidentalis larvae starved within 2–3 days, while immatures of the other three species lived up to 12–14 days, with some becoming adults by cannibalizing and/or scavenging. Phytosciid larvae given eggs, larvae/protochrysalis/protonymphs (L/P), deutochrysalis/deutonymphs (D) or teleiochrysalis/female adult (T/A) of Tetranychus urticae Koch, fed at different incidences during 6 h tests. Larvae of T. pyri never fed, but almost all larvae of M. occidentalis fed on eggs and L/Ps and 60–70% of M. occidentalis larvae fed on Ds and T/As. N. fallacis and A. andersoni larvae fed at incidences from 20–75% depending on the stage of spider mite given. Larvae fed more commonly on eggs and L/Ps than Ds and T/As for M. occidentalis and N. fallacis but not A. andersoni. Protonymphs and deutonymphs of all four species, readily fed on T/As after 3 h of exposure, but incidences were higher for A. andersoni and T. pyri. Feeding on phytoseiid larvae by protonymphs and deutonymphs also was more common for A. andersoni and T. pyri. Except for M. occidentalis, deutonymphs fed more than protonymphs on phytoseiid larvae. Results are discussed in relation to individual species ‘life histories and the value of these traits in predicting a species’ role in a biological control system.

    Description: Ted Henty, noted for his work in the Papua New Guinea National Herbarium (LAE), died aged 86 at East Keilor, near Melbourne on 23 February 2002 after an illness of 6-8 months. Those dealing with New Guinea plants will know of his extensive collections in the NGF and subsequent LAE series from all over the country. The new Composite genus Piora from the alpine grasslands on Mt Piora was just one discovery made in 1963 with S. Carlquist. Those who knew Ted will consider him a fine field botanist, arguably one of the finest that has worked in Papua New Guinea. Not one to involve himself with revisionary studies, he was more concerned with the dissemination of floristic, practical and economic knowledge to the wider user (although with the intensive exploration of Papua New Guinea the opportunities were abundant, Ted never described a new taxon). [The only new combination I know of was made inadvertently: Digitaria microbachne Henrard var. calliblepharata (Henrard) Henrard ex Henty, Bot. Bull., Lae 1 (1969) 77. Ed.] He preferred to call himself a ‘didiman’ (agronomist). He specialised in grasses and weeds, logical as his home life surrounded the farming of cattle and growing tropical fruit up the Markham Valley from Lae. Nevertheless, his knowledge of the broader flora of Papua New Guinea was vast.

    Description: This report represents a first step at considering the potential for the use of market-based incentives to aid in the resolution of fishery bycatch problems. Market-based incentives have several advantages over more traditional command-and-control approaches, including cost-effective allocations of environmental controls; incentives for firms to seek technological solutions; flexibility; returns to the public for the use of its resources; and lower administrative costs in some cases. Notwithstanding these advantages and with several notable exceptions, market-based incentives are almost never employed in the management of fishery bycatch problems. There may be several reasons why this is the case, including significant distributional effects, high costs of monitoring and enforcement, difficulties in educating consumers about product attributes, administrative and transactions costs, or merely oversight. We consider this report to be an "advanced outline" of the issues surrounding the consideration of market-based incentives. We begin first by developing in Section 2 a definition of bycatch, including a "typology" of bycatch types. Next, we compile available public information on bycatch in U.S. fisheries, as defined by target species, location, and gear type (Section 3 and Appendix 1). We then review, in Section 4, two potentially relevant strands of literature, the economic theory of multispecies fisheries and studies from other social sciences of how small-scale fisheries deal with problems of bycatch. In Section 5, we describe, in general, the kinds of market-based policy instruments that may be of use in managing bycatch problems. Following this evaluation, we identify and discuss, as case studies; three priority fisheries: th~ northeastern groundfish fishery; the Gulf of Mexico shrimp fishery; and the eastern tropical Pacific yellowfin tuna fishery (Section 6). Finally, in Section 7, we outline approaches to identifying appropriate policy instruments, including a qualitative comparison of market-based approaches, an examination of the effect of specific types of uncertainty on the choice between taxes and ITQs, and the development of a "proposal" for a bycatch management "policy package." This section concludes with a proposal for a set of priority market-based approaches to bycatch management in the three cases discussed in Section 6.

    Description: In this revision 4 endemic species, one with two varieties, are recognized from the alpine and subalpine regions of New Guinea. Isoetes stevensii Croft, I. hopei Croft, and I. neoguineensis Baker var. rheophila Croft are described as new. Scanning electron micrographs of the megaspores and microspores, which furnish important diagnostic characters, are presented for all the taxa in Papuasia as well as for the possibly related species, I. philippinensis Alston.

    Description: The leaf chlorophyll content (LCC) is an important plant physiological trait and is critical for accurate modeling of vegetation photosynthesis over time and space. To date, there is still a lack of a global long time-series dataset of LCC. In this study, we developed an algorithm to retrieve global LCC from Moderate Resolution Imaging Spectroradiometer (MODIS) surface reflectance data from 2000 to 2020. An essential requirement for generating LCC time series is to capture its seasonal dynamics. This issue was addressed by using a matrix system with two pairs of vegetation indices to minimize the impacts of leaf area index and canopy nonphotosynthetic material on LCC estimation in different seasons. The matrix system algorithm was applied to Landsat data and MODIS data, respectively. The validation based on Landsat data and ground measurements reveals that the algorithm has the ability to catch the seasonal variations of LCC in different plant functional types, and the MODIS-derived LCC shows good agreement with Landsat-upscaled LCC ( R2=0.77 and RMSE = 6.9μg /cm2). The global eight-day LCC data at 500-m resolution in 2000–2020 were generated using the matrix system from MODIS and presented distinct temporal and spatial variations, which provides a new opportunity for analyzing vegetation physiological dynamics in climate change studies.
