ABSTRACT Arctic habitats are changing rapidly and altering trophic webs ecosystem functioning. Understanding how species' abundances distributions differ among is important in predicting future species shifts trophic‐web consequences. We aimed to determine the habitat–abundance relationships for three small herbivores on Seward Peninsula of Alaska, USA by fitting data from 983 point counts (collected during 2019, 2021, 2022) with N‐mixture models that account imperfect detection. These...
Abstract The unclear relationship of obesity to incident melanoma and nonmelanoma skin cancer (NMSC) risks was evaluated in the large, geographically diverse longitudinal, prospective Women's Health Initiative (WHI) observational study. Risks NMSC normal weight women were compared with overweight [body mass index (BMI) = 25–29.0 kg/m2] obese (BMI ≥ 30 kg/m2) women, using Cox proportional hazards models for logistic regression NMSC. Over a mean 9.4 years follow-up, there 386 9,870 NSMC cases....
Most raptor populations are declining and nearly a fifth threatened with extinction; thus there is need to increase collaboration ensure efficient effective research, management, conservation. Here, we introduce the Global Raptor Impact Network (GRIN; www.globalraptors.org), tool enhance conservation impact of research community. We provide an overview history current state GRIN, including plans for expansion. Predecessors GRIN include The African DataBank, which was launched in 2012...
Abstract Bayesian stable isotope mixing models (BSIMMs) for δ 13 C and 15 N can be a useful tool to reconstruct diets, characterize trophic relationships, assess spatiotemporal variation in food webs. However, use of this approach typically requires priori knowledge on the level enrichment occurring between diet tissue consumer being sampled (i.e. discrimination factor or TDF). Trophic factors derived from captive feeding studies are highly variable, it is challenging select appropriate TDF...
The topic of distinguishing atypical fibroxanthoma (AFX) from undifferentiated pleomorphic sarcoma (UPS), formerly malignant fibrous histiocytoma, is highly controversial. Although their clinical behavior disparate, AFX and UPS commonly appear nearly identical on routine histopathologic examination. conceptually useful, subcategorization into superficial (confined to the dermis subcutaneous tissue) deep (involvement fascia deeper structures) types has not improved our ability differentiate...
AbstractThe simple problem of providing a confidence interval for the estimate binomial parameter can prove to be quite interesting. There are suprising variety competing intervals choose from, using both frequentist and Bayes methods. A reasonable criterion comparing these is: How close does actual coverage probability come target probability, over range sample sizes true population proportions? This material lends itself nicely first class in statistical computing. The computation...
Malignant fibrous histiocytoma (MFH) is a rare and aggressive tumor. Mohs micrographic surgery (MMS) has been reported as an effective treatment, although most cases were published before advances in cytopathologic techniques led to reclassification of many tumors.To evaluate contemporary cohort individuals with MFH analyze management practices.We reviewed all diagnosed at our institution from January 1995 December 2010, evaluating 839 records identify 36 patients undergoing tumors the head...
Scoping reviews, in which the literature on a given topic is systematically collated and summarized, aid searches highlight knowledge gaps topic, thus hastening scientific progress informing conservation efforts. Because much research targeted at species level, ornithology bird would benefit from scoping reviews of individual species. We present apply framework for three disparate raptor species: California Condor Gymnogyps californianus , Harpy Eagle Harpia harpyja Gyrfalcon Falco...
Haematophagous ectoparasites can directly affect the health of young animals by depleting blood volume and reducing energetic resources available for growth development. Less is known about effects ectoparasitism on stress physiology (i.e. glucocorticoid hormones) or animal behaviour. Mexican chicken bugs (Haematosiphon inodorus; Hemiptera: Cimicidae) are blood-sucking that live in nesting material nest substrate feed nestling birds. Over past 50 years, range H. inodorus has expanded,...
Stable isotope mixing models (SIMMs) are widely used for characterizing wild animal diets. Such rely upon using accurate trophic discrimination factors (TDFs) to account the digestion, incorporation, and assimilation of food. Existing methods calculate TDFs on controlled feeding trials that time-consuming, often impractical study taxon, may not reflect natural variability present in populations.We TDF
Habitat suitability for breeding birds is defined at scales ranging from the landscape to individual nesting sites. Nesting site characteristics that govern exposure inclement weather may affect success, although attempts understand this effect Arctic raptors have yielded ambiguous results. Further, adults incur substantial costs incubating eggs and brooding nestlings, it possible greater results in increased nest attendance rates, increasing their cost of breeding. We quantified Gyrfalcons...
The Gyrfalcon (Falco rusticolus) is a top avian predator, an Arctic specialist, and among the bird species most vulnerable to climate change. This vulnerability driven by their narrow ecological niche, limited or lack of southward migration, circumpolar distribution where rapid climatic changes are occurring. Climatic habitat may alter disease ecology due in vector distributions, host ranges, pathogen life cycles. Warmer temperatures accompanying landscape also Gyrfalcon's prey base, dietary...

Conservation of predators requires a comprehensive understanding their life history and ecology, including the delineation temporal spatial dietary habits. Gyrfalcons (Falco rusticolus), Willow Ptarmigan (Lagopus lagopus), Rock (L. muta) are Arctic specialists, strongly linked in dynamic predator-prey relationship, facing similar conservation threats. We studied Gyrfalcon predation ptarmigan on Alaska's Seward Peninsula investigated whether species-specific contributions to diet reflected...
