The biogeography of community assembly: latitude and predation drive variation in community trait distribution in a guild of epifaunal crustaceans

While considerable evidence exists of biogeographic patterns in the intensity of species interactions, the influence of these patterns on variation in community structure is less clear. Using a model selection approach on measures of trait dispersion in crustaceans associated with eelgrass (Zostera marina) spanning 30º of latitude in two oceans, we found that dispersion strongly increased with increasing predation and decreasing latitude. Ocean and epiphyte load appeared as secondary predictors; Pacific communities were more overdispersed...

Low-pH seawater alters indirect interactions in rocky-shore tidepools

Brittany Jellison, Brian Gaylord, Aaron Ninokawa, Kristen Elsmore, Gabriel Ng, Jeffrey Miller & Tessa Hill
Ocean acidification is expected to degrade marine ecosystems, yet most studies focus on organismal-level impacts rather than ecological perturbations. Field studies are especially sparse, particularly ones examining shifts in direct and indirect consumer interactions. Here we address such connections within tidepool communities of rocky shores, focusing on a three-level food web involving the keystone sea star predator, Pisaster ochraceus, a common herbivorous snail, Tegula funebralis, and a macroalgal basal resource, Macrocystis pyrifera. We demonstrate that...

Reef Life Survey data (fish and mobile invertebrate counts) from Carrie Bow Cay, Belize, 2015-2019

Aim Conservation efforts have traditionally addressed the threat of biodiversity loss by prioritizing regions and habitats with high endemic species richness. However, species-poor habitats often harbor distinct, valuable, and/or functionally unique species that contribute to regional diversity. In the tropical marine realm, the “mangrove-seagrass-coral reef continuum” has dominated both the scientific literature and marine spatial planning. Bare sediment habitats are also part of this continuum and often comprise the majority of bottom area, as they...

Data from: Insectivorous birds reduce herbivory but do not increase mangrove growth across productivity zones

Alexander Forde, Ilka Feller, John Parker & Daniel Gruner
Top-down effects of predators and bottom-up effects of resources are important drivers of community structure and function in a wide array of ecosystems. Fertilization experiments impose variation in resource availability that can mediate the strength of predator impacts, but the prevalence of such interactions across natural productivity gradients is less clear. We studied the joint impacts of top-down and bottom-up factors in a tropical mangrove forest system, leveraging fine-grained patchiness in resource availability and primary...

Data from: Climate affects the outbreaks of a forest defoliator indirectly through its tree hosts

Kyle Haynes, Andrew Liebhold, Jonathan Lefcheck, Randall Morin & Guiming Wang
Spatial variation in climate is known to affect the survival and reproduction of herbivorous forest insects and tree-species compositions, but the importance of indirect effects of climate on outbreaks of forest insects through its effects on forest composition is unclear. This data was compiled to examine the direct and indirect effects of climate, water capacity of the soil, host tree density, and non-host density on the spatial extent of Lymantria dispar outbreaks in the Eastern...
