Automated identification of spotted-fever tick vectors using convolutional neural networks. [PDF]

Med Vet Entomol
We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.

Host-parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati). [PDF]

Med Vet Entomol
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

Erliquiose canina (“Doença do Carrapato”) sem indícios de carrapatos: Relato de caso [PDF]

Pubvet, 2021
Popularly known as “tick disease”, canine ehrlichiosis is an infectious and endemic disease in several regions of Brazil, including Minas Gerais’ Midwest. Currently, it has been showing a high prevalence where the climate is favorable for the growth of its transmitting agent, the tick Rhipicephalus sanguineus, which during blood repast inoculates the ...

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 ...
