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 ...

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

open access: yesEcological 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

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 ...

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

open access: yesEcological Entomology, EarlyView.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

Evaluación de los efectos de la urbanización en los arroyos de Tierra del Fuego [PDF]

open access: yes, 2017
We set out to understand how urbanization affects streams in Ushuaia, Tierra del Fuego. Paired ttestsand linear regressions were used to compare physico-chemical stream habitat variables (i.e., temperature,turbidity, conductivity, dissolved oxygen and pH)

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.

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

open access: yesEcological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.
