Data from: Bottom-up vs. top-down effects on terrestrial insect herbivores: a meta-analysis

Mayra C. Vidal & Shannon M. Murphy
Primary consumers are under strong selection from resource (“bottom-up”) and consumer (“top-down”) controls, but the relative importance of these selective forces is unknown. We performed a meta-analysis to compare the strength of top-down and bottom-up forces on consumer fitness, considering multiple predictors that can modulate these effects: diet breadth, feeding guild, habitat/environment, type of bottom-up effects, type of top-down effects and how consumer fitness effects are measured. We focused our analyses on the most diverse...

Data from: The relationship between male sexual signals, cognitive performance, and mating success in stickleback fish

Ross Minter, Jason Keagy & Robin M. Tinghitella
Cognitive ability varies dramatically among individuals, yet the manner in which this variation correlates with reproduction has rarely been investigated. Here, we ask 1) do male sexual signals reflect their cognitive ability, and 2) is cognitive ability associated with male mating success? Specifically, we presented threespine sticklebacks (Gasterosteus aculeatus) with a detour-reaching task to assess initial inhibitory control. Fish that performed better were those who solved the detour-reaching task, solved it faster, and required fewer...

Data from: Vegetation response to control of invasive Tamarix in southwestern US rivers: a collaborative study including 416 sites

Eichhorst, Hisham El Waer, Deborah K. Kennard, Rebecca Harms-Weissinger, Annie L. Henry, Lori J. Makarick, Steven M. Ostoja, Lindsay V. Reynolds, W. Wright Robinson & Patrick B. Shafroth
Most studies assessing vegetation response following control of invasive Tamarix trees along southwestern U.S. rivers have been small in scale (e.g., river reach), or at a regional scale but with poor spatial-temporal replication, and most have not included testing the effects of a now widely-used biological control. We monitored plant composition following Tamarix control along hydrologic, soil and climatic gradients in 244 treated and 172 reference sites across six U.S. States. This represents the largest...

Data from: Drosophila studies support a role for a presynaptic synaptotagmin mutation in a human congenital myasthenic syndrome

Mallory C. Shields, Matthew R. Bowers, McKenzie M. Fulcer, Madelyn K. Bollig, Patrick J. Rock, Bryan R. Sutton, Alysia D. Vrailas-Mortimer, Hanns Lochmüller, Roger G. Whittaker, Rita Horvath & Noreen E. Reist
During chemical transmission, the function of synaptic proteins must be coordinated to efficiently release neurotransmitter. Synaptotagmin 2, the Ca2+ sensor for fast, synchronized neurotransmitter release at the human neuromuscular junction, has recently been implicated in a dominantly inherited congenital myasthenic syndrome associated with a non-progressive motor neuropathy. In one family, a proline residue within the C2B Ca2+-binding pocket of synaptotagmin is replaced by a leucine. The functional significance of this residue has not been investigated...
