Noninvasive assessment of corticosterone and triiodothyronine levels in the endangered Pyrenean Capercaillie (Tetrao urogallus aquitanicus)

Journal of Zoology, Volume 327, Issue 2, Page 183-195, October 2025.
Feathers are useful in the study of glucocorticoid and thyroid hormones in Pyrenean Capercaillies. Samples from the Northern Pyrenees and Pre‐Pyrenees contained lower corticosterone concentrations, and a negative correlation was found between corticosterone levels and the distance from cycling trails.

Comparação e Avaliação de Modelos Digitais de Elevação dos sensores SRTM, ASTER, TANDEM/TERRASAR –X, NASADEM, COPERNICUS DEM e ALOS PALSAR para análise digital de terreno para aplicações no saneamento básico

Research, Society and Development, 2023
Modelos Digitais de Elevação (MDEs) são modelos matemáticos que repdroduzem uma superfície topográfica a partir coordenadas cartesianas “x e y”, com atributos altimétricos “z”, sendo que “z” representa a variação de uma superfície. Os MDEs apresentam várias aplicações, podem ser utilizados na gestão de recursos hídricos e ambientais.

Using aerial thermography to map terrestrial thermal environments in unprecedented detail

Methods in Ecology and Evolution, Volume 16, Issue 8, Page 1688-1702, August 2025.
Abstract The accurate quantification of thermal environments is crucial for predicting the impacts of climate change across ecosystems. Two major obstacles exist in mapping biologically relevant thermal landscapes: (1) overcoming the mismatch between the scale at which environmental data are typically collected and the scale at which a particular ...

Quantifying regulatory limits for multiple stressors in an open and transparent way

Conservation Biology, Volume 39, Issue 2, April 2025.
Abstract Biodiversity is confronted globally by multiple stressors. Environmental policies must regulate these stressors to achieve targets, but how should that be done when the outcomes of limits on one stressor are contingent on other stressors, about which there is imperfect knowledge?

Digital soil mapping using multiple logistic regression on terrain parameters in southern Brazil Mapeamento digital de solos utilizando regressões logísticas múltiplas e parâmetros do terreno no sul do Brasil

Scientia Agricola, 2006
Soil surveys are necessary sources of information for land use planning, but they are not always available. This study proposes the use of multiple logistic regressions on the prediction of occurrence of soil types based on reference areas.

Influência da acurácia altimétrica do modelo digital do terreno na elaboração do Índice De Concentração de Rugosidade Global (ICR – Global)

, 2017
Os modelos digitais do terreno (MDTs) possuem varias possibilidades de aplicacao na Geografia. Destaca-se o seu uso no mapeamento geomorfologico manual ou semiautomatico. Mesmo com os constantes avancos cientificos e tecnologicos, os MDTs possuem limitacoes, sendo necessaria avaliacao de qualidade.

Understanding clerical decisions in granting social assistance: Insights from national social security officials in Brazil

International Social Security Review, Volume 78, Issue 1, Page 29-56, January/March 2025.
Abstract Street‐level professionals, such as social workers, shape policy implementation by exerting discretion. However, it remains unclear how other street‐level bureaucrats (SLBs), who are not considered to hold a professional status and who perform highly regulated activities, can do the same. Even though the decision‐making leeway of these SLBs is

Effects of trade and poaching pressure on extinction risk for cacti in the Atacama Desert

Conservation Biology, Volume 38, Issue 5, October 2024.
Abstract In this era of a global biodiversity crisis, vascular plants are facing unprecedented extinction rates. We conducted an assessment of the extinction risk of 32 species and 7 subspecies of Copiapoa, a genus endemic to Chile's fog‐dependent coastal Atacama Desert.
