Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

Wildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Agent-based hantavirus transmission model incorporating host behavior and viral shedding heterogeneities derived from field transmission experiments

Letters in Biomathematics, 2016
Behavioural and environmental heterogeneities among host populations can play an important role in hantavirus transmission. We designed an agent-based model to determine the relative role of direct and indirect transmission on Sin Nombre hantavirus (SNV)

Increased Detection of Sin Nombre Hantavirus RNA in Antibody-Positive Deer Mice from Montana, USA: Evidence of Male Bias in RNA Viremia

Viruses, 2013
Hantaviruses are widespread emergent zoonotic agents that cause unapparent or limited disease in their rodent hosts, yet cause acute, often fatal pulmonary or renal infections in humans.

Development of a low-dose fipronil deer feed: evaluation of efficacy against two medically important tick species parasitizing white-tailed deer (Odocoileus virginianus) under pen conditions

Parasites & Vectors, 2023
Background Odocoileus virginianus (the white-tailed deer) is a key reproductive host for medically important tick species, including Ixodes scapularis and Amblyomma americanum.

Tradeoffs between brain and digestive tissues across elevations in Typhlomys daloushanensis: evidence for sexual dimorphism

Wildlife Biology, EarlyView.
To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

Integrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Sibling rivalry: Males with more brothers develop larger testes

Ecology and Evolution, 2018
When females mate with multiple partners in a reproductive cycle, the relative number of competing sperm from rival males is often the most critical factor in determining paternity.

Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

Maporal Hantavirus Causes Mild Pathology in Deer Mice (Peromyscus maniculatus)

Viruses, 2016
Rodent-borne hantaviruses can cause two human diseases with many pathological similarities: hantavirus cardiopulmonary syndrome (HCPS) in the western hemisphere and hemorrhagic fever with renal syndrome in the eastern hemisphere.

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

Integrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.
