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

open access: yesEntomologia 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 ...

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

open access: yesEcological 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

open access: yesEcological 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 ...

The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

open access: yesEcological Entomology, EarlyView.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...

Reduced fecundity associated with Wolbachia infection in a Neotropical drosophilid Redução da fecundidade associada à infecção por Wolbachia em um drosofilídeo Neotropical

open access: yesEcological Entomology, EarlyView.
Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.
