From confiscation to conservation: Wildlife DNA forensic for species identification of confiscated Felidae in Indonesia.

Illegal wildlife trade poses a significant threat to Indonesia's biodiversity, especially among its diverse Felidae species (cats). While molecular methods have proven effective for identifying some Felidae species, there remains a gap in comparing these techniques across different endemic Felidae species in Indonesia, particularly in cases involving multiple species in confiscated wildlife products. This study applies DNA forensic techniques to analyze 38 confiscated Felidae samples, identifying four species: Sumatran tiger (Panthera tigris sumatrae), leopard (Panthera pardus), leopard cat (Prionailurus bengalensis), and clouded leopard (Neofelis nebulosa).

Intra-specific interactions among top carnivores are among the most intriguing behavioural aspects and essential components of population dynamics. Static interactions pertain to space use, while dynamic interactions involve spatio-temporal patterns influenced by social structure, distribution, mate selection, and density. Previous studies have focused on static interactions, successfully estimating spatial overlap but leading to a knowledge gap of dynamic interaction to be able to compute attraction and avoidance on similar spatio-temporal scales.

Article Synopsis
- The tiger butterfly, part of the Danaidae family, is currently not endangered, leading to its exclusion from major conservation lists, which may hinder local conservation efforts.
- Yunnan's high butterfly diversity makes it an excellent area for studying the tiger butterfly's habitat suitability and overall conservation.
- The study uses the MaxEnt model to predict suitable habitats and finds that interspecies relationships enhance distribution predictions, notably identifying the Yuanjiang River Valley as prime habitat, with a potential increase in suitable areas by 2040.

Conservation initiatives strive for reliable and cost-effective species monitoring. However, resource constraints mean management decisions are overly reliant on data derived from single methodologies, resulting in taxonomic or geographic biases. We introduce a data integration framework to optimize species monitoring in terms of spatial representation, the reliability of biodiversity metrics, and the cost of implementation, focusing on tigers and their principal prey (sambar deer and wild pigs).

Article Synopsis
- Population density is crucial for wildlife management, particularly in the Russian Far East, where methods like the FMP snow tracking are used to estimate ungulate densities and support Amur tiger conservation.
- Despite the effectiveness of FMP, reliability issues due to climate change and survey design challenges prompt the exploration of camera traps as an alternative for monitoring prey density, though their potential is still largely untested.
- A comparative study over three years found that, while both FMP and camera trap methods provided similar prey density estimates, discrepancies in prey biomass calculations highlight the need for caution in management decisions and suggest more research is necessary to improve estimation methods.
