Specialist or generalist? Feeding ecology of the Malagasy poison frog Mantella aurantiaca [PDF]

open access: yes, 2007
We studied the diet of a population of free-ranging Mantella aurantiaca, an alkaloid-containing poison frog from Madagascar. As in other poison frogs, this species is thought to sequester alkaloids from arthropod prey.

Limited impacts of simulated soil disturbance by rewilded vertebrates on above‐ and below‐ground biodiversity

open access: yesOikos, EarlyView.
Rewilding with locally extinct terrestrial vertebrates has been a popular conservation initiative over the past few decades. Among the animals used for rewilding are the small‐ to medium‐sized vertebrates that forage in the soil and that have been lost from many ecosystems due to habitat destruction or predation by exotic species.

Aspects of the taphonomy of the Cambrian Explosion in North Greenland [PDF]

open access: yes, 2017
This thesis describes and elucidates the taphonomic pathways responsible for the exceptional preservation of some of the most common elements of the Sirius Passet Lagerstätte (early Cambrian), North Greenland.

Trophic niche overlap decreases in related mesocarnivore species

open access: yesOikos, EarlyView.
In natural environments, competition between species is a crucial factor for the survival or demise of populations. Therefore, understanding the mechanisms that promote species coexistence is crucial in community and evolutionary ecology. The phylogenetic limiting to similarity hypothesis (PLSH) posits that closely related species should experience ...

A new species of Ribautiella (Myriapoda, Symphyla, Scolopendrellidae) from an Amazonian black-water inundation forest and notes on its natural history and ecology

open access: yes, 1984
Ribautiella amazonica is described from a black-water inundation forest near Manaus, Brazil. The genus is recorded for the first time for the Americas. R. amazonica was predominantly collected from the forest soil, mainly between 7 and 14 cm depth and is

Losers and winners: responses of grassland arthropods to land‐use components

open access: yesOikos, EarlyView.
Intensified land‐use in grasslands reduces biodiversity, particularly affecting arthropod populations. However, responses of individual species vary depending on their ecological traits and habitat requirements. Some species may tolerate or even benefit from intensive land‐use, while others, particularly specialists or those with narrow niches, are ...
