How much do rare and crop-pollinating bees overlap in identity and flower preferences?

Molly MacLeod, James Reilly, Daniel Cariveau, Mark Genung, Michael Roswell, Jason Gibbs & Rachael Winfree
1. The biodiversity-centered approach to conservation prioritizes rare species, whereas the ecosystem services approach prioritizes species that provide services to people. The two approaches align when rare species provide ecosystem services, or when both groups of species benefit from the same management action. We use data on bee pollinators and the plant species they forage on to determine if there are rare species among the most important crop pollinators, and the extent to which plant...

Data from: Predator-induced collapse of niche structure and coexistence on islands

Evangelista, Kiyoko M. Gotanda, , Johanna E. Wegener, Jason J. Kolbe, Thomas W. Schoener, David A. Spiller, Jonathan B. Losos & Rowan D. H. Barrett
Biological invasions represent both a pressing environmental challenge and an opportunity to investigate fundamental ecological processes, such as the role of top predators in regulating species diversity and food-web structure. In whole-ecosystem manipulations of small Caribbean islands where brown anole lizards (Anolis sagrei) were the native top predator, we experimentally staged invasions by competitors (green anoles, A. smaragdinus) and/or novel top predators (curly-tailed lizards, Leiocephalus carinatus). We show that curly-tails destabilized coexistence of competing prey...

Data and numerical methods for determining the dynamics and kinematics of Newark Bay, NJ

W. Bryce Corlett, W. Rockwell Geyer, Robert Chant, David Ralston & Christopher K. Sommerfield
These observational data and numerical methods were used to investigate the subtidal salt balance of Newark Bay, a sub-estuarine network connected to the Hudson River estuary through New York Harbor. The moored data were collected in 2008 by Chant and Sommerfield, and in 2016 by Corlett, Geyer, and Ralston. Corlett devised the included numerical methods. Shipboard measurements of the vertical salinity profile near each mooring were used to reconstruct the tidally-varying vertical salinity profile from...

Data from: Habitat size thresholds for predators: why damselflies only occur in large bromeliads

Diane Sheila Srivastava, Sarah Louise Amundrud, Jacqueline T. Ngai, Brian M. Starzomski & Jessica Lee Ware
Predators are often more sensitive to habitat size than their prey, and frequently occur in only the largest habitats. Four explanations have been proposed for this pattern: (1) small habitats do not have enough energy to support higher trophic levels; (2) small habitats are less likely to contain particular prey required by specialist predators; (3) small habitats are risky for predators with slow life histories or large body sizes; (4) small habitats are numerically unlikely...

Data from: Evolution alters post-invasion temporal dynamics in experimental communities.

Cara Faillace & Peter Morin
1. The causes and consequences of temporal variation in the abundance of organisms constitute central themes in ecological inquiry. Rapid evolution can occur over ecological time scales, potentially resulting in altered temporal variation in abundance and complicating inferences about the consequences of temporal variation. 2. We assessed whether evolution altered the temporal variability in species’ abundances in simple assemblages of species. We then compared experimental results to predictions from two-species models to better understand our...

Data from: A population genetic assessment of taxonomic species: the case of Lake Malawi cichlid fishes

Catarina Pinho, Vera Cardoso & Jody Hey
Organisms sampled for population level research are typically assigned to species by morphological criteria. But if those criteria are limited to one sex or life stage, or the organisms come from a complex of closely related forms, the species assignments may misdirect analyses. The impact of such sampling can be assessed from the correspondence of genetic clusters, identified only from patterns of genetic variation, to the species identified using only phenotypic criteria. We undertook this...

Data from: Male and female bees show large differences in floral preference

Michael Roswell, Jonathan Dushoff & Rachael Winfree
Intraspecific variation in foraging niche can drive food web dynamics and ecosystem processes. In particular, male and female animals can exhibit different, often cascading, impacts on their interaction partners. Despite this, studies of plant-pollinator interaction networks have focused on the partitioning of the floral community between pollinator species, with little attention paid to intraspecific variation in plant preference between male and female bees. We designed a field study to evaluate the strength and prevalence of...

Data from: Specialist foragers in forest bee communities are small, social or emerge early

Colleen Smith, Lucia Weinman, Jason Gibbs & Rachael Winfree
1. Individual pollinators that specialize on one plant species within a foraging bout transfer more conspecific and less heterospecific pollen, positively affecting plant reproduction. However, we know much less about pollinator specialization at the scale of a foraging bout compared to specialization at the species level. 2. In this study, we measured the diversity of pollen carried by individual bees foraging in forest plant communities in the mid-Atlantic United States. 3. We found that individuals...
