Trichophyton mentagrophytes complex: A retrospective study of 64 dogs from the Central United States (1997–2020)

open access: yesVeterinary Dermatology, Volume 34, Issue 4, Page 310-317, August 2023., 2023
Background – There are limited clinical studies evaluating the Trichophyton mentagrophytes complex, with most reports confined to small case studies. Additionally, the studies are dated and provide limited information on response to newer or currently available therapies.

Seasonality in niche occupation revealed through bird community functional structure in the southern Atlantic rainforest

open access: yesIbis, Volume 165, Issue 3, Page 986-997, July 2023., 2023
Seasonal variation in tropical and subtropical systems can have different effects on bird species depending on the resources they use and how they use them. However, despite recent research advances, knowledge of the drivers of the presence and abundance of species in different seasons is still limited for most tropical bird species.

Climate and crown damage drive tree mortality in southern Amazonian edge forests

open access: yesJournal of Ecology, Volume 110, Issue 4, Page 876-888, April 2022., 2022
Tree death is a key process for our understanding of how forests are responding to global change. Our long‐term research shows that more than 70% of all trees dying in this critical region at the edge of Amazonia already had markedly broken and damaged crowns years before they died.

Distinct leaf water potential regulation of tree species and vegetation types across the Cerrado–Amazonia transition

open access: yesBiotropica, Volume 54, Issue 2, Page 431-443, March 2022., 2022
Our article finds that dominant species from a tall woodland savanna have similar leaf water potential regulation than savanna species and different than forest species at the Amazonia–Cerrado transition. Abstract The Cerrado–Amazonia transition harbors forest and savanna formations under the influence of pronounced climate seasonality; however, the ...

Variation of non‐structural carbohydrates across the fast–slow continuum in Amazon Forest canopy trees

open access: yesFunctional Ecology, Volume 36, Issue 2, Page 341-355, February 2022., 2022
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Tropical tree species span a range of life‐history strategies within a fast–slow continuum. The position of a species within this continuum is thought to reflect a negative relationship between growth and storage, with fast‐growing species allocating ...

Fisheries management influences phytoplankton biomass of Amazonian floodplain lakes

open access: yesJournal of Applied Ecology, Volume 58, Issue 4, Page 731-743, April 2021., 2021
Tropical freshwaters fisheries typically assume that fish biomass is controlled by bottom‐up mechanisms, so that overexploitation of large predators would not affect overall ecosystem productivity. Our results, however, show that top‐down forces are important drivers of primary productivity in tropical lakes, above and beyond the effects of bottom‐up ...

Sazonalidade de Haematobia irritans no Brasil Central [PDF]

open access: yesPesquisa Veterinária Brasileira, 2006
A mosca-dos-chifres (Haematobia irritans) é um dos principais ectoparasitos de bovinos no Brasil. Estudos epidemiológicos são exigidos devido às dificuldades crescentes do seu controle químico. Por isso, para um melhor conhecimento da dinâmica populacional sazonal desta mosca foram realizadas contagens a cada 14 dias sobre bovinos para corte, entre 7 e
