Data from: Invasive species reduces parasite prevalence and neutralizes negative environmental effects on parasitism in a native mosquito

Katie M. Westby, Brenden M. Sweetman, Thomas R. Van Horn, Elizabeth G. Biro & Kim A. Medley
1.Invasive species research often focuses on direct effects of invasion on native ecosystems and less so on complex effects such as those influencing host‐parasite interactions. However, invaders could have important effects on native host‐parasite dynamics. Where infectious stages are ubiquitous and native host‐pathogen specificity is strong, invasive less‐competent hosts may reduce the pool of infectious stages, effectively reducing native host‐parasite encounter rate. Alternatively, invasive species could alter transmission via changes in native species abundance. 2.Biotic...

Data from: Snail herbivory affects seedling establishment in a temperate forest in the Ozark region

Anna J. Liang, Claudia Stein, Eleanor Pearson, Jonathan A. Myers, Raelene M. Crandall & Scott A. Mangan
1. Species-specific herbivores are hypothesized to maintain plant diversity by preventing the dominance of any one plant species. However, a large proportion of herbivores have wide host ranges, and these generalists could have similar effects on plant community composition if they exhibit differences in their host preference. Here, we coupled lab and field experiments to test whether a common forest-understory snail (Neohelix alleni), a generalist herbivore, has the potential to influence forest composition through differential...

Data from: Patterns of nitrogen-fixing tree abundance in forests across Asia and America

Symbiotic nitrogen (N)‐fixing trees can provide large quantities of new N to ecosystems, but only if they are sufficiently abundant. The overall abundance and latitudinal abundance distributions of N‐fixing trees are well characterised in the Americas, but less well outside the Americas. Here, we characterised the abundance of N‐fixing trees in a network of forest plots spanning five continents, ~5,000 tree species and ~4 million trees. The majority of the plots (86%) were in America...

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 from: TSPO PET Using [18F]PBR111 reveals persistent neuroinflammation following acute diisopropylfluorophosphate intoxication in the rat

Brad A. Hobson, Douglas J. Rowland, Sílvia Sisó, Michelle A. Guignet, Zachary T. Harmany, Suren Bandara, Naomi Saito, Danielle J. Harvey, Donald A. Bruun, Joel R. Garbow, Abhijit J. Chaudhari & Pamela J. Lein
Acute intoxication with organophosphates (OPs) can trigger status epilepticus followed by persistent cognitive impairment and/or electroencephalographic abnormalities. Neuroinflammation is widely posited to influence these persistent neurological consequences. However, testing this hypothesis has been challenging, in part because traditional biometrics preclude longitudinal measures of neuroinflammation within the same animal. Therefore, we evaluated the performance of non-invasive positron emission tomography (PET), using the translocator protein (TSPO) radioligand [18F]PBR111 against classic histopathologic measures of neuroinflammation in a preclinical...

Mental Health Service Use Of Youth Leaving Foster Care (Voyages) 2001-2003

Curtis McMillen, Lionel Scott & Wendy Fran Auslander
The study was funded to explore the changes in mental health service use as older youth leave the foster care system. The data, however, examine many parameters of the lives of older youth in the foster care system, from their perspective. Four-hundred six youth in the Missouri foster care system were interviewed in person near their 17th birthday. They were re-interviewed when possible every three months until their 19th birthday. Eighty percent of the youth...
