Assessing spider community structure in a beech forest: Effects of sampling method

European Journal of Entomology, 2000
The spider community of a beech forest on limestone was studied for one year using four sampling techniques: emergence traps, pitfall traps, soil samples, and arboreal eclectors. 87 spider species were recorded.

Inter–Annual Variability of Model Parameters Improves Simulation of Annual Gross Primary Production

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Parametric uncertainty can hinder land surface models (LSM) from accurately simulating carbon fluxes, such as gross primary production (GPP). These models generally cannot capture inter–annual variability (IAV) of fluxes well due to missing processes, and temporally varying parameters can partially alleviate this limitation.

Interspecific phenological variation in herbaceous species is more strongly reflected in vegetative traits than in floral traits

Journal of Ecology, Volume 114, Issue 6, June 2026.
Our study confirms that vegetative traits offer a robust explanatory framework for phenology, while also emphasizing the value of considering both vegetative and floral traits in understanding these patterns. Our findings offer a basis for exploring the functional relevance of rarely measured floral traits, such as pollen traits, within the plant ...

Hazards to Wild Birds Associated with Anthropogenic Structures and Human Activities—Results of a Long-Term Study in an Urbanised Area of the Alps

Birds
We analyse data from a rescue database collected at the Innsbruck Alpenzoo (Tyrol, Austria). The sample covers 33 years (1988–2020), and more than 5250 wild birds from 145 species originating from Innsbruck and the surrounding Inn Valley, one of the most

Clarifying the Size–Frequency Relationship in Clownfish Acoustic Signals

Ecology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Body size is the principal determinant of acoustic variation in anemonefish, reflecting both the mechanics of sound production and the size‐based structure of their social hierarchies. In Amphiprion percula, the absence of a reported size‐frequency relationship has led to the interpretation that small acoustic differences are rank‐specific. We

The making of novel ecosystems: A process‐based framework for measurement, analysis and application

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 683-704, March 2026.
Abstract Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land‐use transformation. These changes challenge how we assess, understand and manage ecosystems in the Anthropocene.

Forest Heterogeneity by Chain Saw: How Between‐Patch Variation in Old Growth Attributes Changes the Metacommunities of Beetles

Ecology Letters, Volume 29, Issue 3, March 2026.
Metacommunity theory has expanded our understanding of how spatial dynamics and local interactions influence species communities, but we lack empirical studies specifically in terrestrial habitats testing which archetype is most important. In a replicated design we experimentally enhanced structural between‐patch heterogeneity in homogeneous production

Peering into the world of wild passerines with 3D‐SOCS: Synchronized video capture and posture estimation

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 339-356, February 2026.
Abstract Collection of large behavioural data‐sets on wild animals in natural habitats is vital in ecology and evolution studies. Recent progress in machine learning and computer vision, combined with inexpensive microcomputers, has unlocked a new frontier of fine‐scale markerless measurements.
