Metacommunity patterns in larval odonates

open access: yesOecologia, 2008
The growth of metacommunity ecology as a subdiscipline has increased interest in how processes at different spatial scales structure communities. However, there is still a significant knowledge gap with respect to relating the action of niche- and dispersal-assembly mechanisms to observed species distributions across gradients.

Vegetation trajectories over 150 years of temporary ponds created in the Camargue delta (Southern France)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Temporary ponds in the Mediterranean climate have a high conservation value, but many have been severely destroyed or degraded. Pond restoration and new pond creation have been engaged widely. Evaluations of the success of such operations are generally carried out over 10–15 years and show divergent results over this timeframe. In

Biogeography of Endemic Dragonflies of the Ozark-Ouachita Interior Highlands [PDF]

open access: yes, 2019
A common pattern across many taxonomic groups is that relatively few species are widespread while the majority are restricted in their geographic ranges. Such species distributions are used to inform conservation status, which poses unique challenges for

Unexpected Evolutionary Divergence of Tachykinin‐Positive Neurons Innervating the Central Complex in Hexapods

open access: yesJournal of Comparative Neurology, Volume 534, Issue 3, March 2026.
The central complex is a group of midline‐spanning neuropils in the brain of insects with a key role in goal‐directed orientation and navigation. Immunolabeling in 25 species, ranging from bristletails to flies, shows that neurons containing peptides of the tachykinin family of neuropeptides are present in most species studied.

Inconsistent effects of P enrichment and predator presence on food‐web dynamics in a bromeliad system

open access: yesOikos, Volume 2026, Issue 3, March 2026.
Food webs consist of trophic interactions of variable strength. However, it remains challenging to predict how changes in environmental conditions, such as nutrient enrichment, can affect these interactions. In this paper, we propose to integrate food web theory with ecological stoichiometry, which predicts how elemental ratios affect trophic ...

Toward a global repository of insect traits (GRIT)

open access: yesInsect Conservation and Diversity, Volume 19, Issue 2, Page 253-267, March 2026.
Biodiversity loss is accelerating, yet insect conservation is hindered by the absence of a centralised, comprehensive trait database. We propose the GRIT, a FAIR, open‐access platform uniting datasets and collaborators worldwide. GRIT will harness advanced computational tools for trait acquisition and imputation, enabling large‐scale ecological ...
