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.

Promoting landscapes with a low zoonotic disease risk through forest restoration: The need for comprehensive guidelines

Journal of Applied Ecology, Volume 60, Issue 8, Page 1510-1521, August 2023., 2023
Our results contribute to a more comprehensive forest restoration planning, comprising multiple ecosystem services and resulting in healthier landscapes for both people and nature. Our framework could be integrated into the post‐2020 global biodiversity framework targets.

A DNA barcode reference library of Portuguese mosquitoes

Zoonoses and Public Health, Volume 68, Issue 8, Page 926-936, December 2021., 2021
Abstract Mosquitoes are important biological vectors of pathogens and species identification in all life stages is the first step for effective monitoring and control of mosquito‐borne diseases. Molecular methods for species identification have been developed over the last years to overcome the limitations of the taxonomic identification based on ...

Endangered Lymphocytes: The Effects of Alloxan and Streptozotocin on Immune Cells in Type 1 Induced Diabetes

Mediators of Inflammation, Volume 2021, Issue 1, 2021., 2021
Alloxan (ALX) and streptozotocin (STZ) are extensively used to induce type 1 diabetes (T1D) in animal models. This study is aimed at evaluating the differences in immune parameters caused by ALX and STZ. T1D was induced either with ALX or with STZ, and the animals were followed for up to 180 days. Both ALX and STZ induced a decrease in the total number

Evaluation of sustainable susceptibility to Plasmodium vivax infection among colonized Anopheles darlingi and Anopheles deaneorum

Malaria Journal, 2022
Background The colonization of mosquitoes susceptible to Plasmodium vivax via direct membrane feeding assay (DMFA) has the potential to significantly advance our knowledge of P. vivax biology, vector-parasite interaction and transmission-blocking vaccine

Taxonomy of the thelyphonid genus Typopeltis Pocock, 1894, including homology proposals for the male gonopod structures (Arachnida, Thelyphonida, Typopeltinae) [PDF]

ZooKeys, 2019
The genus Typopeltis Pocock, 1894 is poorly known regarding its systematics, natural history, and distribution, despite important taxonomic advances during the 1990s.

O VETOR TERRITORIAL E O VETOR RETICULAR DA SEGURANÇA INTERNACIONAL

GEOgraphia, 2022
O presente artigo busca pensar a segurança internacional em termos geográficos, discutindo a dimensão espacial da segurança, geralmente negligenciada nos estudos realizados pelas disciplinas que tradicionalmente se aprofundam no assunto. São dois enfoques para explorar a dimensão geográfica da segurança: territórios (e fronteiras) e redes (e fluxos ...

Population variation in early development can determine ecological resilience in response to environmental change

New Phytologist, Volume 226, Issue 5, Page 1312-1324, June 2020., 2020
Summary As climate change transforms seasonal patterns of temperature and precipitation, germination success at marginal temperatures will become critical for the long‐term persistence of many plant species and communities. If populations vary in their environmental sensitivity to marginal temperatures across a species’ geographical range, populations ...
