Tendencias en ingeniería genética del uso de modelos animales
, 2021 Los modelos animales son “organismos vivos en los cuales pueden ser estudiados fenómenos de interés y en los cuales estos fenómenos se parecen de cierto modo al del animal objetivo”, es decir el humano [1].

Remote Sensing in Ecology and Conservation, EarlyView.Parameter choices in acoustic analyses (sampling frequency, FFT size and window overlap) strongly influence multivariate soundscape separation. Using terrestrial and coral reef recordings, we show that these settings can exaggerate or mask ecological differences, emphasizing the need for parameter sensitivity testing and transparent reporting in ...

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 ...

ÉTICA DE LA INVESTIGACIÓN EN MODELOS ANIMALES DE ENFERMEDADES HUMANAS
, 2007 El presente artículo reflexiona sobre las implicaciones éticas de usar modelos animales para el desarrollo de la medicina en seres humanos. Entre las posturas extremas de condenar toda investigación con animales considerándola irrelevante y la de ...

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 ...

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.

Reflujo enterogástrico. Modelo experimental en ratas.
Cirugía del Uruguay, 2001 Se crea un modelo de reflujo enterogástrico en ratas y se realizan procedimientos antireflujo. Se estudian las alteraciones producidas por el reflujo enterogástrico sobre la mucosa gástrica. Se emplean 5 series de 1 O animales.
