Context‐aware UAV LiDAR reveals forest structure and improves tree diameter estimates in subalpine forest

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
In this study we show how, in natural forests, tree heights adapt across environmental gradients as a response to environmental and biotic factors. Awareness of such local adaptations can be encoded into predictive features and leveraged by shallow learning methods to enhance predictions of tree diameter and tree‐level aboveground biomass.

The Windy City Rookery: Movement and Activity Patterns of Black‐Crowned Night Herons (Nycticorax nycticorax) in a Human‐Dominated Landscape

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Black‐crowned night herons (BCNH) are a cryptic, widely distributed colonial wading bird. Despite showing regional declines in North America, this species has successfully adapted to colonize urban areas. In this study, our team used GPS/GSM transmitters to explore the space use, habitat use, and diel activity patterns of BCNH breeding at the largest ...

Exchanging Genes Within a City: Analysis of Pollen Flow Patterns in a Narrow Endemic Plant Species Threatened by Urbanisation

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Anthropogenic habitat fragmentation can severely disrupt gene flow in endemic plants that depend on species‐specific native pollinators with limited dispersal ability. Using paternity analysis across fragmented and continuous populations, we found that pollen flow was maintained in intact bushland but was completely absent between fragments separated ...

Modeling Benthic Animals in Space and Time Using Bayesian Point Process With Cross Validation: The Case of Holoturians

open access: yesEnvironmetrics, Volume 37, Issue 3, April 2026.
ABSTRACT Holothurian populations in the Mediterranean are relatively understudied, with limited knowledge of their spatial distribution, habitat preferences, and ecological dynamics, making their monitoring a key challenge for ecosystem assessment and sustainable management.
