The launch of Animal Biotelemetry aims to provide a forum for discussion on telemetric techniques used in various animal species. Key findings include the two-year migration pattern of female white sharks and the use of UV radiation to prevent infections in tagged animals.
Researchers found that Italian wolves primarily consume wild boar, accounting for two-thirds of their diet, with roe deer making up around a third. The study suggests that wolves prefer wild boar even when roe deer densities are high, indicating a strong preference for this prey.
A 20-year study at Harvard Forest Long-Term Ecological Research site reveals that leaving storm-damaged trees intact allows native plants and wildlife to thrive. The forest recovers naturally, with original conditions recovering more readily than after salvage logging.
Recent studies have begun to explore the connections between animal microbiomes and behavior, showing that beneficial microbes can influence animal behaviors such as feeding, mating, and predator-prey interactions. The study suggests that behavior plays a critical role in establishing microbiomes, which then influence animal behavior.

African cities are experiencing rapid growth, transforming natural resource use and affecting rural areas. The main driver of deforestation is not fuel wood demand but rather agricultural land clearing in peri-urban areas to feed growing urban populations.
Global warming may threaten tropical plant and animal species living in mountainous regions, forcing them to move uphill in search of suitable climates. This could lead to the extinction of half of the studied species in Costa Rican lowlands unless they develop tolerances for higher temperatures.
