Estimativas de parâmetros genéticos para características incluídas em critérios de seleção em gado Nelore Estimates of genetic parameters for the traits included in selection criteria for Nelore cattle

Ciência Rural, 2001
Foram analisados registros de 20 rebanhos integrantes do Programa de Melhoramento Genético da Raça Nelore (PMGRN), estudando-se as seguintes variáveis: ganho de peso por dia de idade até os 120, 200, 310 e 350kg (GPDpesok), peso padrão aos 120, 240, 365 ...

Knee height is often right: evaluating device height effects on camera trapping rate

Remote Sensing in Ecology and Conservation, EarlyView.
Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...

Modelos de regressão aleatória na avaliação genética do crescimento de ovinos da raça Santa Inês Random regression models on genetic evaluation on the growth of Santa Inês breed sheep

Revista Brasileira de Zootecnia, 2010
Utilizaram-se 17.767 registros de peso de 4.210 cordeiros da raça Santa Inês com o objetivo de comparar modelos de regressão aleatória com diferentes estruturas para modelar a variância residual em estudos genéticos da curva de crescimento.

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

When Norms Meet Markets: Environmental Governance and Digital Fast‐Fashion Platforms in Brazil

Sustainable Development, EarlyView.
ABSTRACT Environmental governance increasingly relies on consumer‐based mechanisms that assume that sustainability awareness translates into purchasing behaviour. This article investigates whether such mechanisms remain effective when consumption is organised through transnational digital platforms in contexts characterised by socioeconomic inequality.

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Crítica al modelo animal en psicopatología: el caso de las obsesiones-compulsiones

Desde el Jardín de Freud
El modelo animal para conocer las supuestas bases de aprendizaje o neurobiológicas del trastorno mental ha tomado relevancia en los últimos 50 años. Se compartiría con algunos animales, como los perros o las ratas, ciertas organizaciones neurológicas de
