Data from: Dietary niche constriction when invaders meet natives: evidence from freshwater decapods

Michelle C. Jackson, Jonathan Grey, Katie Miller, J. Robert Britton & Ian Donohue
1. Invasive species are a key driver of global environmental change, with frequently strong negative consequences for native biodiversity and ecosystem processes. Understanding competitive interactions between invaders and functionally similar native species provides an important benchmark for predicting the consequences of invasion. However, even though having a broad dietary niche is widely considered a key factor determining invasion success, little is known about the effects of competition with functionally similar native competitors on the dietary...

Data from: Taxonomic notes on the genus Piper (Piperaceae)

Chalermpol Suwanphakdee, David A. Simpson, Trevor R. Hodkinson & Pranom Chantaranothai
Sixteen lectotypifications of Asian Piper species are provided. Piper argyrites, P. baccatum, P. leptostachyum, P. majusculum, P. peepuloides, P. quinqueangulatum and P. sulcatum are accepted as species and many new synonyms are proposed. Useful diagnostic characters are described and geographical distribution data of each species are provided.

Data from: Plant toxin levels in nectar vary spatially across native and introduced populations

Paul A. Egan, Phillip C. Stevenson, Erin Jo Tiedeken, Geraldine A. Wright, Fabio Boylan & Jane C. Stout
Secondary compounds in nectar can function as toxic chemical defences against floral antagonists, but may also mediate plant-pollinator interactions. Despite their ecological importance, few studies have investigated patterns of spatial variation in toxic nectar compounds in plant species, and none outside their native range. Grayanotoxin I (GTX I) occurs in nectar of invasive Rhododendron ponticum where it is toxic to honeybees and some solitary bee species. We examined (i) geographic variation in the composition of...

Data from: Biocontrol insect impacts population growth of its target plant species but not an incidentally used nontarget

Haley A. Catton, Robert G. Lalonde, Yvonne M. Buckley & Rosemarie A. De Clerck-Floate
Understanding the impact of herbivory on plant populations is a fundamental goal of ecology. Damage to individual plants can be visually striking and affect the fates of individuals, but these impacts do not necessarily translate into population-level differences in vital rates (survival, growth, or fecundity) or population growth rates. In biological control of weeds, quantitative assessments of population-level impacts of released agents on both target invasive plants and native, nontarget plants are needed to inform...

Data from: Predators inhibit brain cell proliferation in natural populations of electric fish, Brachyhypopomus occidentals

Kent D. Dunlap, Alex Tran, Michael Ragazzi, Rudiger Krahe, Vielka Salazar, Michael A. Ragazzi & Vielka L. Salazar
Compared to laboratory environments, complex natural environments promote brain cell proliferation and neurogenesis. Predators are one important feature of many natural environments, and, in the laboratory, predatory stimuli tend to inhibit brain cell proliferation. Often, laboratory predator stimuli also elevate plasma glucocorticoids, which can then reduce brain cell proliferation. However, it is unknown how natural predators affect cell proliferation or whether glucocorticoids mediate the neurogenic response to natural predators. We examined brain cell proliferation in...
