Phylogeography and population structure of the tsetse fly Glossina pallidipes in Kenya and the Serengeti ecosystem

Norah Saarman, Rosemary Bateta, Winnie Okeyo, Kirstin Dion, Paul Mireji, Sylvance Okoth, Imna Malele, Grace Murilla, Serap Aksoy & Adalgisa Caccone
Glossina pallidipes is the main vector of animal African trypanosomiasis and a potential vector of human African trypanosomiasis in eastern Africa where it poses a large economic burden and public health threat. Vector control efforts have succeeded in reducing infection rates, but recent resurgence in tsetse fly population density raises concerns that vector control programs require improved strategic planning over larger geographic and temporal scales. Detailed knowledge of population structure and dispersal patterns can provide...

Data from: Dispersal increases the resilience of tropical savanna and forest distributions

Nikunj Goel, Vishwesha Guttal, Simon Levin & Carla Staver
Global change may induce changes in savanna and forest distributions, but the dynamics of these changes remain unclear. Classical biome theory suggests that climate is predictive of biome distributions, such that shifts will be continuous and reversible. This view, however, cannot explain the overlap in the climatic ranges of tropical biomes, which some argue may result from fire-vegetation feedbacks, maintaining savanna and forest as bistable states. Under this view, biome shifts are argued to be...

Heterogeneity of posttraumatic stress symptomatology and social connectedness in treatment-seeking military veterans: a longitudinal examination

Lauren M. Sippel, Laura E. Watkins, Robert H. Pietrzak, Rani Hoff & Ilan Harpaz-Rotem
Elucidating whether PTSD symptoms predict poorer social connectedness over time (i.e. social erosion) and/or that poor social connectedness contributes to maintenance of PTSD (i.e. social causation) has implications for PTSD treatment and relapse prevention. Most extant research has been cross-sectional and examined overall PTSD symptoms. Evidence of longitudinal associations among heterogeneous PTSD symptom clusters and social connectedness could provide insight into more nuanced targets for intervention. Using data from 1,491 U.S. military veterans in residential...

Concerns of surrogate decision makers for acute brain injury patients: a US population survey

David Hwang
Objective: To determine whether groups of surrogates for severe acute brain injury (SABI) patients with poor prognosis can be identified based on their prioritization of goals-of-care (GOC) decisional concerns, an online survey of 1588 adults recruited via a probability-based panel representative of the US population was conducted. Methods: Participants acted as a surrogate for a GOC decision for a hypothetical SABI patient and were randomized to one of two prognostic scenarios: the patient likely being...
