Acoustic Localisation as a Tool to Aid Monitoring of Golden Jackals ().

Golden jackals () have rapidly expanded their range across Europe, raising ecological and socioeconomic concerns. As a highly vocal species, jackals can be monitored using howl surveys or passive acoustic monitoring (PAM) to estimate population sizes and habitat preferences. A recent advancement in PAM is acoustic localisation, which estimates the source of sounds by measuring the time differences of their arrival at multiple synchronised recorders.

Utilisation of Anthropogenic Food by Red Foxes () in Britain as Determined by Stable Isotope Analysis.

Dietary analyses utilising visual methods to identify stomach and faecal contents have shown that urban red foxes () in Britain consume human-derived (anthropogenic) food to varying degrees. Anthropogenic foods have been implicated in poor health outcomes for synanthropic species that consume them; therefore, it is important to examine the degree of such foods in the British fox diet. We analysed the carbon (δC) and nitrogen (δN) stable isotope ratios of whiskers collected from 93 foxes from across Britain to determine: (1) if stable isotope analysis (SIA) distinguished a difference in δC and δN between rural and urban foxes, and whether any difference was suggestive of anthropogenic food use; (2) the proportion of anthropogenic food consumption in urban foxes compared to rural foxes using a Bayesian mixing model; (3) whether sex, age or season of collection influenced fox diet as assessed by SIA, in relation to anthropogenic food use.

Minireview: Applications of NMR-based metabolomics for the detection and characterisation of toxoplasmosis in felids.

Toxoplasmosis is an infection caused by the intercellular protozoan parasite . The parasite has the three-stage life cycle: oocysts, tachyzoites, and bradyzoites. Felids are the only known hosts for the sexual reproduction of and, therefore, play a crucial role in the transmission of toxoplasmosis.
