Microbiome‐mediated immunity: Limited support from the gazelle dung beetle

open access: yesEcological Entomology, EarlyView.
Digitonthophagus gazella rely on a maternally inherited microbiome passed across generations via a maternal faecal pellet called the pedestal. We experimentally manipulated the presence of the pedestal, providing it to some individuals while withholding it from others to determine how pedestal microbiota may affect beetle immune potential.

Why we Should Study Solitary Species to Understand the Costs of Group‐Living

open access: yesEthology, EarlyView.
It's easier to measure the benefits than the costs of a trait. Solitary species benefit by avoiding the costs of group living. Thus, measuring benefits of solitary living informs us about the costs of group living. ABSTRACT While for decades behavioral ecologists have studied the benefits of group living, measuring its costs has been more difficult. It

Leaders Are Somethin' Else: Behavioural Variation Associated With Roles During Tandem Running Recruitment

open access: yesEthology, EarlyView.
In this study, we found moderate to strong repeatabilities in behavioural variables measuring the personality traits: activity, aggressiveness and exploration. Similarly, the probability of acting as a leader during tandem running in an emigration event was moderately (R = 0.469) repeatable.

Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

Fire‐driven forest degradation enhances termite activity and accelerates litter decomposition in the Amazonia rainforest

open access: yesInsect Conservation and Diversity, EarlyView.
Forest degradation increased termite‐mediated litter decomposition, whereas no such effect was detected in undisturbed forests. Reduced ant predation and altered forest conditions were associated with higher termite abundance and faster litter decomposition.
