Gyrfalcon Prey Abundance and Their Habitat Associations in a Changing Arctic.

Arctic habitats are changing rapidly and altering trophic webs and ecosystem functioning. Understanding how species' abundances and distributions differ among Arctic habitats is important in predicting future species shifts and trophic-web consequences. We aimed to determine the habitat-abundance relationships for three small herbivores on the Seward Peninsula of Alaska, USA by fitting data from 983 point counts (collected during 2019, 2021, and 2022) with N-mixture models that account for imperfect detection.

Robotic-Assisted Cholecystoduodenal Fistula and Bile Leak Repair.

Cholelithiasis and its complications are among the most prevalent and costly medical conditions in the United States. Chronic gallbladder disease can progress into more complicated conditions, such as a cholecystoenteric fistula and, more specifically, a cholecystoduodenal fistula (CDF). Repair of these fistulas is complex and usually performed with an open approach.

African savanna raptors show evidence of widespread population collapse and a growing dependence on protected areas.

The conversion of natural habitats to farmland is a major cause of biodiversity loss and poses the greatest extinction risk to birds worldwide. Tropical raptors are of particular concern, being relatively slow-breeding apex predators and scavengers, whose disappearance can trigger extensive cascading effects. Many of Africa's raptors are at considerable risk from habitat conversion, prey-base depletion and persecution, driven principally by human population expansion.

Conserving the evolutionary history of birds.

In the midst of the sixth mass extinction, limited resources are forcing conservationists to prioritize which species and places will receive conservation action. Evolutionary distinctiveness measures the isolation of a species on its phylogenetic tree. Combining a species' evolutionary distinctiveness with its globally endangered status creates an EDGE score.

Eagles enter rotor-swept zones of wind turbines at rates that vary per turbine.

There is increasing pressure on wind energy facilities to manage or mitigate for wildlife collisions. However, little information exists regarding spatial and temporal variation in collision rates, meaning that mitigation is most often a blanket prescription. To address this knowledge gap, we evaluated variation among turbines and months in an aspect of collision risk-probability of entry by an eagle into a rotor-swept zone (hereafter, "probability of entry").

Towards reconciliation of the four world bird lists: hotspots of disagreement in taxonomy of raptors.

There are currently four world bird lists referenced by different stakeholders including governments, academic journals, museums and citizen scientists. Consolidation of these lists is a conservation and research priority. In reconciling lists, care must be taken to ensure agreement in taxonomic concepts-the actual groups of individual organisms circumscribed by a given scientific epithet.

Reducing Length of Stay Does Not Increase Emergency Room Visits or Readmissions in Patients Undergoing Primary Hip and Knee Arthroplasties.

Background: Total hip and total knee arthroplasty (total joint arthroplasty [TJA]) are 2 of the most common elective surgeries. Identifying which patients are at highest risk for emergency room (ER) visits or readmissions within 90 days of surgery and the reasons for return are crucial to formulate ways to decrease these visits and improve patient outcomes.

Methods: This is a retrospective review of a consecutive series of 7466 unilateral primary TJA performed from July 2013 to June 2017; any patients who had an ER visit or readmission in the first 90 days after surgery were identified, and a detailed chart review was performed.

A pilot study of rhythm and timing training as a supplement to occupational therapy in stroke rehabilitation.

Introduction: Stroke is the leading cause of disability. A need exists for an effective intervention to enhance upper extremity (UE) motor abilities and activities of daily living (ADL) performance.

Objective: The objectives of this pilot study were to (1) determine the feasibility of adding Interactive Metronome (IM) to an occupational therapy (OT) program; and (2) determine changes in UE impairments, function, quality of life, and perceived physical performance ability and satisfaction using a combined IM + OT regimen compared with OT alone for adults with chronic stroke.
