Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Predatory Behavior of Leucauge magnifica (Araneae: Tetragnathidae)

open access: yesActa Arachnologica, 2000
The predatory behavior of Leucauge magnifica was studied. This species employed five predatory sequences: seize-pull out, bite-pull out, bite-wrap, wrap-bite, and wrap. Attack wrapping was used to subdue various types of prey such as grasshoppers, damselflies, ants and stinkbugs, which may be large and/or dangerous prey.

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

open access: yesEcography, EarlyView.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

Alpine ungulates adjust diel activity to the natural return of wolves amid anthropogenic pressures

open access: yesEcography, EarlyView.
As wolves recolonise their historical range across Europe, ungulates face predation once more – but in landscapes profoundly altered by human activity. This shift raises crucial questions about their capacity to express adaptive antipredator behaviours.

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

open access: yesEcography, EarlyView.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Emotions and policy change in the wake of political scandals: How did the Qatargate shake the European Parliament?

open access: yesEuropean Policy Analysis, EarlyView.
Abstract While there is an increasing interest in the role of emotions in policy studies, not much is known about how emotions unfold in one of the most emotional situations that can be encountered in politics: political scandals. To investigate how the discursive articulation of emotions shapes the policy responses to political misconduct from a ...

Policy Networks and Policy Entrepreneurship in the EU: Explaining Structural Policy Change in Pharmaceutical Innovation Incentives and Health Technology Assessment

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT Policy process research has excelled in explaining structural policy change within national settings, but extensions and applications to the EU level have long proven challenging for scholars. Given that the EU is currently experiencing its longest period of Treaty stability since the 1980s—having evolved into a sui generis political system ...
