Temporal and spatial patterns in the shifting of otter diet to invasive prey after river damming

River Research and Applications, Volume 38, Issue 8, Page 1450-1459, October 2022., 2022
Abstract River damming promotes profound changes in aquatic biodiversity, including the facilitation of biological invasions, with subsequent impacts on native communities. The Eurasian otter (Lutra lutra) is a generalist aquatic predator that often incorporates new prey types when they become available.

Hotspots in the grid: Avian sensitivity and vulnerability to collision risk from energy infrastructure interactions in Europe and North Africa

Journal of Applied Ecology, Volume 59, Issue 6, Page 1496-1512, June 2022., 2022
We identify the areas of Europe and North Africa that are most sensitive for the specific populations of birds for which sufficient GPS tracking data at high spatial resolution were available. We also map vulnerability hotspots where mitigation at existing EI should be prioritised to reduce collision risks.

Camera trapping and spatially explicit capture–recapture for the monitoring and conservation management of lions: Insights from a globally important population in Tanzania

Ecological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022
While for many large carnivores population density is often estimated through spatially explicit capture‐recapture (SECR) applied to camera trap data, the lack of pelage patterns in lions has limited the application of this technique to the species. Here, we show that by using xenon‐flash camera traps, combined with consistent framing and angles of ...

New histochemical and morphological findings in the female genital tract of Boophilus microplus (Acari, Ixodidae): an attempt toward the elucidation of fertilization in ticks Novas características histoquímicas e morfológicas no trato genital feminino de Boophilus microplus (Acari: Ixodidae): uma tentativa para a elucidação da fertilização nos carrapatos

Iheringia: Série Zoologia, 2005
At present not only is the site of fertilization in ticks still unknown but it is also unclear as to how this mystery can be solved. Signs of fertilization can be observed throughout the female genital tract and these can be clues for the elucidation of ...
