AbstractIn contemporary times, wildlife managers attempt to provide solutions to problems arising from conflicting uses of the environment by humans and nonhuman animals. Within the Kangaroo Management Zones of New South Wales (NSW), the commercial culling "solution" is one such attempt to perpetuate kangaroo populations on pastoral land while supporting farmers in continuing inefficient sheep farming. Because wildlife management rests on a distinction between the "nature" of humans and animals, then humanist attention to standards of individual welfare need not interrupt the process whereby individual animals are killed within an economic framework designed to improve habitat management for the conservation of their populations. Building on Thorne's (1998) discussion of the meanings scripted onto individual kangaroo bodies, this paper explores the utilitarian underpinnings of the commercialization approach and considers the ethical implications of constructing the population as resource, even if this results in an improvement in the welfare of individual kangaroos.

AbstractNinety-five percent of orchid species associated with fynbos shrublands of South Africa's Cape Floristic Kingdom have been assessed for the IUCN Red List, yet aspects of their demography and population biology remain poorly understood. We conducted a 6-year demographic study of the Critically Endangered Disa procera, a cryptic, terrestrial species from South Africa with a global population of c. 50 individuals known from a single location. We aimed to provide management recommendations that would facilitate its persistence. Our findings indicate that the population of D. procera is larger than previously thought, and the species occurs at two distinct locations. These orchids exhibit high interannual variation in population size and turnover of individuals, potentially indicative of a species with a short life span, and still meet the criteria for Critically Endangered status. The species benefits from disturbances, such as brush cutting along trails, or fire, which open up clearances in the vegetation. However, physical damage to plants during their aboveground growing season (September–January) is particularly detrimental and should be avoided in habitat management for the species. Fire had beneficial effects at the population and individual levels and is recommended at 10–25-year intervals, outside the orchid's growing season. The species exhibited comparatively high rates of fruit set (68%), suggesting that pollination limitation does not currently constrain its performance. Its patchy distribution may, however, indicate constraints on dispersal or recruitment. We recommend that management strategies should include continued protection and monitoring of both populations, studies on pollination, habitat requirements and mycorrhizal associates, and a prescribed disturbance regime.

Ceropegia odorata Nimmo ex J. Graham (Apocynaceae: Asclepiadoideae) a Critically Endangered plant species from India was recorded in Gujarat after about 45 years in Vijaynagar forest of Sabarkantha District (northern Gujarat).  It was first collected from Pavagadh in central Gujarat.  Long-term conservation and participatory approaches, details on macro- and micro-habitats, associated species, landscape level monitoring programs are suggested for the new recorded locality and hill ranges.

AbstractDietary studies are critical for understanding foraging strategies and have important applications in conservation and habitat management. We applied a robust metabarcoding protocol to characterize the diet of the critically endangered freshwater fish Zingel asper and conducted modelling and simulation analyses to characterize and identify some of the drivers of individual trophic trait variation in this species. We found that intra-specific competition and ontogeny had minor effects on the trophic niche of Z. asper. Instead, our results suggest that the majority of trophic niche variation was driven by seasonal variation in ecological opportunity (in our case, the seasonal variation in the availability of preferred prey types). Overall, our results are in line with the optimal foraging theory and suggest that Z. asper is specialized on a few ephemeropteran prey species (Baetis fuscatus and Ecdyonurus) but adapts its foraging by becoming more opportunistic as its favoured prey seasonally decline. Despite the now widespread usage of metabarcoding, very few studies have attempted to study inter- and intra-populational individual trophic traits variation with metabarcoding data. This study illustrates how metabarcoding data obtained from feces can be combined with modelling and simulation approaches to test hypotheses in the conventional analytic framework of trophic analysis.
