Phylogenetic signal in the circadian rhythm of morphologically convergent species of Neotropical deer [PDF]

Mammalian Biology, 2016
Deer species included in the genus Mazama descend from two different clades that experienced a strong evolutionary convergence in morphology and behaviour when they adapted to Neotropical forests. We would expect that circadian activity rhythms also converged according to habitat features or responded to temporal niche segregation in sympatric species.

The effect of white‐tailed deer density on breeding songbirds in Delaware

Wildlife Society Bulletin, 2013
Most population goals for white‐tailed deer (Odocoileus virginianus) are based solely on deer data, with little consideration for other parts of the ecosystem. A wider ecological approach is needed for more justifiable target deer densities.

Assessment of transplacental transmission of Neospora caninum and Toxoplasma gondii in Neotropical deer: An estimative based on serology

Veterinary Parasitology, 2022
Transplacental transmission of Neospora caninum and Toxoplasma gondii is well known in some domestic species and despite both parasites having been proved to infect deer fetuses during gestation, the congenital transmission rate in South-American deer species is still unknown. This study aimed to estimate the congenital transmission rate of neosporosis

First report of complete albinism in Mazama americana (Erxleben, 1777) in the Biological Reserve of Tapirapé, Oriental Amazon, Brazil

Acta Scientiarum: Biological Sciences, 2020
Albinism is a genetic condition that results in total hypopigmentation of the eyes, fur, skin, hair, scales, and feathers of an organism. Albinism might result in a selective disadvantage for affected animals.

Endoparasites of Selected Native Non-Domesticated Mammals in the Neotropics (New World Tropics)

Veterinary Sciences, 2019
In this review, information was summarized on endoparasites found in six non-domesticated neotropical animals. These mammals have the potential to be domesticated. The animals included three rodents, agouti (Dasyprocta leporina), lappe (Agouti paca), and

Movements of Neotropical Forest Deer: What Do We Know?

, 2019
Neotropical forest deer comprise a range of species distributed in a wide variety of habitats. Due to that diversity, movement patterns studies of free-ranging deer are unequally distributed among the different species. Studies with Hippocamelus bisulcus examine altitudinal movements between seasons and in association with reproduction. H.

Natural Habitat, Housing, and Restraint of Six Selected Neotropical Animals in Trinidad and Tobago with the Potential for Domestication

Scientifica, 2020
This paper highlights the natural habitat, housing, and restraint needs of 6 Neotropical animals that are found in Trinidad and Tobago with the potential for domestication: agouti (Dasyprocta leporina), lappe/paca (Cuniculus paca/Agouti paca), capybara ...

Potential effects of climate change on the water level, flora and macro-fauna of a large neotropical wetland. [PDF]

PLoS ONE, 2013
Possible consequences of climate change in one of the world's largest wetlands (Ibera, Argentina) were analysed using a multi-scale approach. Climate projections coupled to hydrological models were used to analyse variability in wetland water level ...

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.

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).
