A new acoustic telemetry tag that identifies carrier mortality by monitoring activity level

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1735-1742, June 2026.
Abstract We present a new acoustic telemetry tag capable of detecting whether its carrier stops moving for long enough to presume the organism has died, and of reporting the time elapsed since movement ceased. The tag uses existing environmental sensor technology together with an algorithm with user‐specifiable thresholds, and importantly, can separate

Multiple global‐change drivers and cascading effects in Mediterranean ecosystems: Lessons from an iconic national park

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

Six decades of data indicate reduced zooplankton density with warming conditions in Iliamna Lake, Alaska, USA

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Zooplankton, a key component in lake ecosystems, are affected by planktivore grazing pressure, phytoplankton, and climate‐driven factors such as water temperature and, in lakes at mid‐high latitudes, the duration of ice coverage. Efforts to assess the relative effects of climate and planktivores on zooplankton are complicated in many large ...
