TL;DR: The results indicate that traffic mortality has a significant negative effect on the local density of anurans and suggest that recent increases in traffic volumes worldwide are probably contributing to declines in amphibian populations, particularly in populated areas.

TL;DR: In this article, the applicability of capture-recapture models for estimating tiger Panthera tigris numbers from camera-trap data was investigated in a part of Nagarahole National Park, India during 12 months (387 trap-nights) in 1991-92.

TL;DR: Investigation of forests in the boreal zone of Sweden investigated the effects of selective cuttings on wood-inhabiting fungi from the families Polyporaceae, Hymenochaetaceae and Corticiaceae found these species showed pronounced preferences for well decayed and large logs.

TL;DR: In this paper, the international significance of upland heather moorland, changes in its Great Britain (GB) extent, and some management and policy objectives for nature conservation are reviewed.

TL;DR: It is concluded that adequately designed culverts can aid the conservation of vertebrate populations through the movement of vertebrates through roads and railways in Central Spain.

TL;DR: In this paper, the authors investigated whether temporary ponds were markedly different from more permanent ponds in terms of their species richness, species rarity and community type, and found that the number of aquatic species was significantly lower in the temporary ponds.

TL;DR: A method of sensitivity analysis for population viability models is presented that uses logistic regression to evaluate the importance of model parameters that influence the risks of extinction and demonstrates that a simple expression containing the parameters of the model can encapsulate predictions of risk.

TL;DR: In this paper, the authors investigated the effects of commercial forestry on canopy-living invertebrates in the boreal forest, and found that the number of large invertebrate (> 2·5 mm, the minimum prey size for foraging passerine birds) was consistently higher in natural forests, with spiders (Araneae), Lepidoptera and Diptera larvae dominating.

TL;DR: Although the situation in the Czech Republic is at present not critical, the ability of I. glandulifera to outcompete native flora, and its predicted expansion along water courses, indicates that it could become a more serious threat to nature conservation in the future.

TL;DR: Except in limited circumstances, genus richness appears to be an unreliable surrogate for species richness in local Australian ant faunas and may apply more generally to taxa in which a relatively small number of genera can contribute a large proportion of species.

TL;DR: It is essential to initiate conservation action plans, for each catchment in wetland areas rich in endemic fish, and an awareness campaign directed at land managers and decision-makers on the role and importance of fish in the functioning of aquatic ecosystems must be undertaken very soon.

TL;DR: The primary forest vegetation and the secondary plant communities in Xishuangbanna, an important region for the conservation of biodiversity in China, are discussed with comments and suggestions for nature conservation as mentioned in this paper.

TL;DR: There is a strong positive correlation between ithomiine species richness and the overall species richness of all other butterflies across all areas, and the proportion of this subfamily is reasonably invariant, suggesting that it may be possible to use the species total of a single butterfly group (an indicator) to predict the overallspecies richness ofall other butterflies in an area.

TL;DR: In this article, the authors compared rabbit use of experimentally burned and unburned scrubland areas and found that rabbit activity was significantly higher in burned areas, with the greatest use in less productive habitats in close proximity to scrub cover.

TL;DR: The results showed that, in general, the forest-farm edges of southwestern Illinois did not attract significantly more individuals or species of nesting songbirds, but they did have higher nest predation levels than forest interior sites, primarily as a result of higherpredation levels on sapling nests.

TL;DR: The results indicate that 41 species of fauna of south-eastern Australia undergo a reduction in bioclimatic range in response to climatic warming, the most extreme response being the extinction of bioc climatic range.

TL;DR: In this paper, a 200m long plot at varying distances from six mid-order streams in Vermont, USA to determine how wide corridors need to be to conserve biological richness was used.

TL;DR: In this paper, an experimental fence was built along the boundary of Ol Ari Nyiro Ranch in western Laikipia in 1992, and the response of the elephants was monitored.

TL;DR: The main problems are caused by engineering works, industrial and domestic pollution, acidification, fishing and fishery management, and land use practices as discussed by the authors, and the major conservation objective must be habitat restoration and management, but short-term programs can usefully involve translocations, captive breeding and cryopreservation.

TL;DR: A metapopulation model is investigated to see how marine reserves might help to conserve such populations and benefit fisheries, and it is shown that reserves become highly beneficial as the local extinction rate caused by fishing becomes large because they provide a source of recruitment into fished-out patches.

TL;DR: It is anticipated that fish translocations and the technology required to support them will expand along with future needs and desires to re-establish native biotic elements in depleted communities and ecosystems.

TL;DR: The culture of juvenile Margaritifera margarITifera in cages is shown to be a useful method of raising the early post-parasitic stages in suitable rivers for scientific or conservation purposes.

TL;DR: Methods for organizing a critical plan to safeguard the most endangered species or subspecies in the Mediterranean region by captive breeding are suggested.

TL;DR: In this article, a metapopulation modelling approach to population viability analysis (PVA) is proposed to identify habitat patchiness from an endangered species' point of view using spatial information on habitat suitability.

TL;DR: In Italy, there is a unique assemblage of endemic freshwater fishes, but most have either been deliberately or accidentally introduced to areas outside their natural range, and the result of this persistent practice is zoogeographic pollution, massive cases of hybridization and loss of genetic identity by local native populations.

TL;DR: In this article, permanent quadrats were used to study the changes in vegetation and environment at Askham Bog, a small valley mire near York, UK, over a period of 13 years by resurveying sites recorded in 1978 and by studying permanent quadrat.

TL;DR: In the British county of Hertfordshire, from presence/absence data in grid squares before and after 1970, this paper showed that complete extinction took place in 66·9% of 2 km squares occupied before 1970 (average for 18 species).

TL;DR: In this article, South African estuaries are evaluated using single-criterion and multiple-criteria scoring indices and an iterative technique and the viability of alternative scoring indices for more qualitative data is examined.

TL;DR: In this paper, a study was conducted in linear remnants of sclerophyll woodland along a highway in southwestern Australia and the authors documented the invasion of native vegetation by exotic species after fire.

TL;DR: In this article, the authors evaluated counts of track sets on 48 randomly chosen quadrats in California, each quadrat contained 33.8 km of transect on dusty, dirt roads, which were chosen by local biologists.
