Savanna aliens

Numerous alien plant species are invading African savannas causing loss of biodiversity and altering ecosystem functioning. The ecological factors and underlying mechanisms causing these invasions are poorly understood. This hinders invasive species management and biodiversity conservation.

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 ...

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

Ecological 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 ...

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

Ethology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.
