PREFERÊNCIAS TÉRMICAS DE VACAS LEITEIRAS EM SISTEMA DE CONFINAMENTO FREESTALL

open access: yesRevista Brasileira de Engenharia de Biossistemas, 2007
As mudanças do microclima de alojamento podem promover alterações no comportamento animal, onde fica priorizada sua preferência térmica. As medidas convencionais são pouco precisas, podendo levar a eventual erro na interpretação dos resultados.

Extensões via splines da análise em componentes principais

open access: yes, 2012
A new approach to generalize Principal Components Analysis (PCA) in order to handle nonlinear structures is proposed in this thesis: quasi-linear PCA (qlPCA). It includes spline transformations of the original variables, using Alternating Least Squares fitting of a suitable objective loss function to achieve optimal transformations.

Mapping priority areas to mitigate the risk of electrocution of range‐restricted bird species

open access: yesJournal of Applied Ecology, Volume 62, Issue 10, Page 2787-2799, October 2025.
Our study proposes a framework to identify areas with higher electrocution risk, which can be used even in data‐scarce regions or adapted to a multi‐species assessment context. This approach can support proactive strategies for energy companies with an initial assessment identifying areas to avoid installing new power lines, evaluating sites for ...

Computed tomographic myelography of the cranial cervical spine in Warmblood horses with no spinal pathology—Inter‐ and intravertebral ratios and distribution of contrast columns in neutral and flexed cervical spine

open access: yesEquine Veterinary Journal, Volume 57, Issue 5, Page 1375-1386, September 2025.
Abstract Background Computed tomographic myelography (CTM) and radiographic myelography (RxM) are diagnostic for extradural spinal cord compression, but knowledge about the contrast distribution in flexion and normal position of nonaffected horses is lacking.

Limited evidence of biodiversity spillover from forest fragments into oil palm plantations in the Amazon

open access: yesJournal of Applied Ecology, Volume 62, Issue 8, Page 1939-1952, August 2025.
Converting primary forest into oil palm plantations results in substantial biodiversity losses, highlighting the urgent need to preserve the few remaining large forest fragments in the area. Measures that enhance matrix permeability are essential to conserving the evolutionary and functional integrity of Amazonian landscapes and mitigating the negative

Transcriptomic profiling of dorsal root ganglia in atopic and healthy dogs: A comparative RNA sequencing study with implications in cutaneous itch research

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 401-411, August 2025.
Background – Itch is a common symptom in skin disorders. While the neural pathways of itch transmission from the skin to the brain are well‐understood in rodents, the same pathways in dogs remain unclear. The knowledge gap hinders the development of effective treatments for canine itch‐related disorders.
