MODELAGEM DA ALTURA DE Pinus caribaea var. hondurensis EM DIFERENTES ESPAÇAMENTOS

BIOFIX Scientific Journal, 2017
Apesar do Pinus ser um gênero nativo do hemisfério norte, sua introdução nas regiões equatoriais ocorre gradativamente desde as últimas décadas, demonstrando sua capacidade de adaptabilidade e rusticidade.

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 ...

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 ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

Animal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

Prediction of the one-repetition maximum based on the maximum number of repetitions with submaximal loads in women.

Revista Brasileira de Cineantropometria e Desempenho Humano, 2011
The objective of the present study was to determine equations that could be used to estimate the load corresponding to the one-repetition maximum (1RM) based on the maximum number of repetitions (MNR) using submaximal loads in bench press, lat machine ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership
