Importance: Pressure ulcers (PUs) are (1) prevalent secondary complications after spinal cord injury (SCI), (2) present with elevated systemic inflammatory tone, and (3) may interfere with healing processes underlying neurological recovery (disrepair).
Objective: To investigate whether PUs acquired during initial hospitalization are associated with neurological and functional long-term outcome and survival after SCI.
Design, Setting, And Participants: Multicenter cohort study at 20 centers of the prospective SCI Model Systems (SCIMS) Database (Birmingham, AL).
Large terrestrial mammals increasingly rely on human-modified landscapes as anthropogenic footprints expand. Land management activities such as timber harvest, agriculture, and roads can influence prey population dynamics by altering forage resources and predation risk via changes in habitat, but these effects are not well understood in regions with diverse and changing predator guilds. In northeastern Washington state, USA, white-tailed deer (Odocoileus virginianus) are vulnerable to multiple carnivores, including recently returned gray wolves (Canis lupus), within a highly human-modified landscape.

Design: Retrospective pre-post study design.
Setting: Single Level II Trauma Center.
To manage predation risk, prey navigate a dynamic landscape of fear, or spatiotemporal variation in risk perception, reflecting predator distributions, traits, and activity cycles. Prey may seek to reduce risk across this landscape using habitat at times and in places when predators are less active. In multipredator landscapes, avoiding one predator could increase vulnerability to another, making the landscape of fear difficult to predict and navigate.
