Posttraumatic stress disorder prevalence among former first responders: A systematic review and meta‐analysis

Journal of Traumatic Stress, EarlyView.
Abstract First responders are at high risk of posttraumatic stress disorder (PTSD), yet little research has examined PTSD prevalence within this population after individuals retire or resign from service. The current study is the first systematic review and meta‐analysis aiming to describe the evidence available on point and lifetime PTSD prevalence ...

Differences in bird and bat traits, seed-dispersal interactions and functions between tropical montane forest and bracken-dominated areas

Frontiers in Ecology and Evolution
Most tropical plant species depend on animals to disperse their seeds. Seed dispersal by animals allows plants to colonize new sites in deforested habitats helping to accelerate forest recovery.

Chemotaxis of Bracken Spermatozoids : The Role of Bimalate Ions [PDF]

, 1958
1. Bracken spermatozoids are chemotactically attracted by malic acid salts and in a pH gradient aggregate between pH 3.5 and 5.6. 2. This response to pH occurs only when the sperm suspension contains malate. 3. At higher pH's, the response to an H+

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

Potential uses for bracken (Pteridium aquilinum (L.) Kuhn) in organic agrculture [PDF]

, 2006
Bracken is a weed species due to its toxic nature and adverse effects on agriculture and ecology. This poster reviews research into historical uses for fronds and litter harvested as part of organically approved control methods.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Region Operators of Wigner Function: Transformations, Realizations and Bounds

, 2005
An integral of the Wigner function of a wavefunction |psi >, over some region S in classical phase space is identified as a (quasi) probability measure (QPM) of S, and it can be expressed by the |psi > average of an operator referred to as the region ...

Depth‐dependent mechanisms regulate accumulation of plant‐ and microbial‐derived residues under long‐term nitrogen addition in a semiarid grassland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐ and microbial‐derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth‐dependent mechanisms governing their accumulation remain ...
