The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

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

Methods in Ecology and Evolution, EarlyView.
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.

Low-frequency gravitational radiation from coalescing massive black hole binaries in hierarchical cosmologies

, 2004
We compute the expected gravitational wave signal from coalescing massive black hole (MBH) binaries at the center of galaxies in a hierarchical structure formation scenario in which seed holes of intermediate mass form far up in the dark halo merger tree.
