What Goes First? Effects of Starvation on the Body Condition of a Neotropical Dung Beetle

Entomologia Experimentalis et Applicata, EarlyView.
We investigated how prolonged starvation affects key physiological traits in the dung beetle Dichotomius bos. Prolonged starvation leads to significant reductions in body dry mass and fat reserves, while muscle mass remains unchanged. These findings indicate that dung beetles prioritize the maintenance of locomotor muscles while mobilizing stored ...

Seasonality as a structuring factor of the dung beetle community in burned neotropical savannas

Ecological Entomology, EarlyView.
We tested the effects of fire, vegetation cover and seasonality on dung beetle communities, focusing on species richness, composition and co‐occurrence patterns in savannas. Fire did not affect species richness. However, seasonality was the dominant factor influencing species composition, followed by fire and vegetation cover.

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

Ecological Entomology, EarlyView.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

Ecological Entomology, EarlyView.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

La categoría jurídica “sujeto/objeto” y su insuficiencia respecto de los animales. Especial referencia a los animales usados en laboratorios

Revista de Bioética y Derecho, 2009
La experimentación con animales abre debates éticos de gran complejidad, que están en mayor o menor medida, recogidos en legislaciones que buscan regular el área. Entendiendo la necesidad que tiene para el avance de la ciencia la experimentación con animales, en este artículo expongo cómo la importancia moral de los animales ha ido asumiendo forma en ...
