Functional diversity in agricultural landscapes: evidence of long‐term clustering and multi‐scale effects of land use on avian communities

Oikos, EarlyView.
Functional diversity (FD) is an essential community property connecting biodiversity, ecosystem functioning, and conservation objectives. In agricultural landscapes, avian communities, which play key functional roles, are facing large‐scale biodiversity erosion, largely due to land‐use changes.

The effect of light availability and spatio‐temporal heterogeneity on the soil seed bank diversity in temperate forests

Oikos, EarlyView.
Light is a key driver of understory plant diversity, also important for seed germination, yet its effect on forests soil seed bank diversity remains underexplored. This study assessed the impact of both light availability and spatio‐temporal heterogeneity on soil seed bank diversity.

Individual tree detection and counting based on high-resolution imagery and the canopy height model data

Geo-spatial Information Science
Individual Tree Detection-and-Counting (ITDC) is among the important tasks in town areas, and numerous methods are proposed in this direction. Despite their many advantages, still, the proposed methods are inadequate to provide robust results because ...

Bottom–up and top–down drivers influence urbanization effects on insect herbivory in oaks

Oikos, EarlyView.
Urban forests provide essential ecosystem services, including pest control, biodiversity conservation, and human health benefits. Herbivory is a widespread biotic interaction that shapes ecosystem functions, such as primary productivity and soil fertility, which underpin these services.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.
