Foreign body ingestions in children and adolescents: A position paper of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) endoscopy special interest group

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Foreign body (FB) ingestion is a relatively frequent occurrence in the pediatric population with multiple potential sequelae. Appropriate intervention may range from urgent endoscopic retrieval to watchful waiting, with multiple variables influencing the decision.

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Effects of a large woody debris accumulation on channel-bed morphology during flood events

E3S Web of Conferences, 2018
A novel experimental setup for the laboratory was designed in order to investigate large woody debris accumulations and their influence on hydraulic flow conditions and channel morphology at a river cross-section.

Beyond a dual role: how Purpureocillium lilacinum reprograms citrus metabolism for integrated biocontrol and growth promotion

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.

Impacts of Forest Cutting and Wood Removal on Saproxylic Insects: Conservation Implications from a Multi-Year Case Study of an Elusive Stag Beetle (Coleoptera: Lucanidae)

Conservation
Saproxylic insects are key forest components but highly vulnerable to practices that reduce deadwood quality and diversity. We investigated the response of Platycerus caraboides (Coleoptera: Lucanidae)—an elusive, cool-adapted stag beetle associated with

The art of avoidance: bedsite use, antipredator strategies, and predation risk in white‐tailed deer fawns

The Journal of Wildlife Management, EarlyView.
Horizontal visibility, rather than concealment cover, drove fawn bedsite use and predation risk. Greater field of view decreased the odds of coyote predation, likely by facilitated by early detection. As fawns transitioned from hiders to followers, they shifted from using dense overstory concealment to more open overstory that favored improved escape ...

Structure and hydraulics of natural woody debris jams

Water Resources Research, 2007
Numerous studies exist on the hydraulics of woody debris jams and the mechanisms driving their geomorphic influence. While most hydraulic studies treat jams as single, solid objects, jams are clearly not individual cylindrical logs but rather an accumulation of pieces ranging in size from leaves and twigs to entire trunks.

Habitat characteristics along spring migration routes of elk, mule deer, and pronghorn in the southern San Juan Mountains

The Journal of Wildlife Management, EarlyView.
We evaluated habitat characteristics of spring migration routes and stopover sites for adult female elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) in the San Juan Mountains (2021–2022) and found species‐specific differences in vegetation structure, terrain, and proximity to land cover types relative to ...
