Using Smartphones to Determine Hummingbird Dominance Networks in Quinde Ecotourist‐Route, Ecuador

Biotropica, Volume 57, Issue 4, July 2025.
Hummingbird aggression networks and a hierarchical meta‐network were built with dominance interactions recorded with smartphone videos in artificial hummingbird feeders in the Quinde Eco Route in Ecuador, and calculating David's scores with wins and loss rates.

Phytosociological surveys: tools for weed science? Levantamentos fitossociológicos: ferramentas para a ciência das plantas daninhas?

Planta Daninha, 2013
In simple terms, a phytosociological survey is a group of ecological evaluation methods whose aim is to provide a comprehensive overview of both the composition and distribution of plant species in a given plant community. To understand the applicability

Rainfall seasonality shapes belowground root trait dynamics in an Amazonian tropical rainforest: A test of the stress‐dominance hypothesis

Functional Ecology, Volume 39, Issue 3, Page 799-812, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stress‐dominance hypothesis (SDH) predicts that trait variation at the community level increases with the availability of limiting resources, driving spatial and temporal patterns in above‐ground plant functional trait expression.

Evaluating the role of frequency‐dependent selection in controlling the expansion of clonal aggregations in the tropical forest's understorey: Insights from a decade‐long experiment

Functional Ecology, Volume 39, Issue 3, Page 851-862, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual reproduction, despite its associated costs and risks, is prevalent among many organisms, presumably to generate and maintain genetic diversity. This diversity is vital for adapting to environmental changes and combating natural enemies.

Landscape composition and orchard management effects on bat assemblages and bat foraging activity in apple crops

Ecosphere, Volume 16, Issue 1, January 2025.
Abstract Bats are acknowledged as suppliers of essential ecosystem services such as insect pest control in agroecosystems. Little is known, however, on how bat assemblages respond to the gradients imposed by anthropogenic landscapes and farming practices and how these environmental effects translate into changes in bat foraging.

Tree traits are a stronger predictor of bee traits and species richness than taxonomic diversity

Functional Ecology, Volume 39, Issue 1, Page 281-292, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits help to understand biological diversity and the mechanism by which ecological communities are structured and how they respond to the environment. For example, the high tree species diversity within tropical forests can be grouped into a few functional ...

Soil carbon and nitrogen cycling at the atmosphere–soil interface: Quantifying the responses of biocrust–soil interactions to global change

Global Change Biology, Volume 30, Issue 10, October 2024.
Despite the critical role of biological soil crusts (biocrusts) in dryland C and N cycles, little is known about how biocrust‐derived C and N move into the soil. This study reveals how biocrusts facilitate the downward movement of C and N and drive the formation of mineral‐associated organic matter in subcrust soils.
