Coronaviruses have been documented to replicate in numerous species of vertebrates, and multiple spillovers coronaviruses from animals into humans founded human epidemics. The COVID-19 epidemic likely derived a spillover SARS-CoV-2 bats humans, possibly via an intermediate host.
Summary The structure of communities is influenced by the transport resources across ecosystem boundaries. Seabirds are capable introducing large amounts marine‐derived nutrients to land, thereby modifying resource availability terrestrial species. In this study we investigated hypothesis that variation in nesting densities great black‐backed gulls Larus marinus and double‐crested cormorants Phalacrocorax auritus would modify effect these species on soil plant composition offshore islands...
ABSTRACT Since 1998, cyclic mortality events in common eiders ( Somateria mollissima ), numbering the hundreds to thousands of dead birds, have been documented along coast Cape Cod, MA, USA. Although longitudinal disease investigations uncovered potential contributing factors responsible for these outbreaks, detecting a primary etiological agent has proven enigmatic. Here, we identify novel orthomyxovirus, tentatively named Wellfleet Bay virus (WFBV), as causative outbreaks. Genomic analysis...
We studied the vanA-carrying vancomycin-resistant enterococci (VRE) isolated from American crows in United States during winter 2011/2012. Faecal samples were cultured selectively for VRE and characterized. Pulsed-field gel electrophoresis (PFGE) multilocus sequence typing (MLST) used to examine epidemiological relationships of vanA-containing VRE. Isolates tested vitro their ability horizontally transfer vancomycin resistance trait. with vanA gene found 15 (2.5%) 590 samples, which we...
The prevalence of antibiotic-resistant bacteria in the marine environment is a growing concern, but degree to which mammals, seabirds and fish harbor these organisms not well documented. This project sought identify occurrence patterns antibiotic resistance isolated from vertebrates coastal waters northeastern United States. Four hundred seventy-two isolates clinical interest were tested for suite 16 antibiotics. Fifty-eight percent resistant at least one antibiotic, while 43% multiple A...
Studies in parts of Europe, New Zealand, and North America indicate uptake anticoagulant rodenticides (ARs) by predatory mammals to be widespread common, with proximity urban agricultural areas being an important driver exposure. Yet, little is known regarding the patterns drivers AR exposure within more forest-dominated landscapes. Across northeastern United States (US), a region spanning Pennsylvania Maine, we tested livers from 597 fisher ( Pekania pennanti ) obtained legal harvest for 11...
The ability to rapidly respond wildlife health events is essential. However, such are often unpredictable, especially with anthropogenic disturbances and climate-related environmental changes driving unforeseen threats. Many also short-lived go undocumented, making it difficult draw on lessons learned from past investigations. We report the response a mortality event observed predominantly in wild passerines eastern United States. began May 2021 when rehabilitators private citizens reported...
Zoonotic diseases have received significantly more attention over the last few decades, emerging with increasing frequency and causing majority of notable disease outbreaks in this century, including COVID-19 pandemic. As human activities shifting climate patterns induce changes environment that alter habitat range reservoir species, potential for animal interactions will increase enhance opportunity spillover. Thus, any emergency response preparedness planning must take into account...
There has been considerable debate in the study of hybrid zones as to whether hybrids may be superior parental types within area contact (bounded superiority). In birds, naturally occurring hybridization is relatively common, and this group always involves mate choice. If are superior, females choosing heterospecific mates should expected show higher fitness under conditions prevalent zone. Hybrid superiority these circumstances would reduce reinforcement thereby help maintain To examine...
Abstract: Livestock have grazed on salt marshes for centuries and dramatic effects marsh vegetation. Most studies examining the of livestock focused plants rather than fauna or ecological processes. However, grazers such as feral horses may strong indirect communities by altering habitat, making it more less suitable species that potentially occur there. We evaluated grazing estuarine animals use adjacent subtidal communities. Surveys revealed horse‐grazed had vegetation, a higher diversity...
Although there is a large body of research on food webs in rocky intertidal communities, most the emphasis has been marine benthic components. Effects avian predation highly mobile predators such as crabs, remains practically unstudied shore ecosystems. The crab, Cancer borealis, an important component diet gulls (Larus marinus, L. argentatus) at Isles Shoals, Maine, USA. C. borealis prey include predatory gastropod Nucella lapillus L., herbivore Littorina littorea, and mussels Mytilus...
Wildlife may facilitate the spread of antibiotic resistance (AR) between human-dominated habitats and surrounding environment. Here, we use functional metagenomics to survey diversity genomic context AR genes in gulls. Using this approach, found a variety not previously detected gulls wildlife, including class A C β-lactamases as well six tetracycline gene types. An analysis flanking sequences indicates that most these are present Enterobacteriaceae various Gram-positive bacteria. In...
Numbers of Great Black-backed Gulls (Larus marinus) and Herring (L. argentatus) along coastal New England have changed dramatically during the last century. In recent years, displaced from optimal breeding sites, thus potentially contributing to decline Gull. Although quality foraging habitat is also a strong determinate reproductive success, potential for competition interactions between these two species in natural habitats been largely ignored. this study, diet prey preference were...
Wildlife may be an important reservoir of antibiotic-resistant bacteria and resistance genes. In this pilot study, the prevalence patterns antimicrobial in Escherichia coli cultured from wild herring gull (Larus argentatus) feces human wastewater at Cape Cod, Massachusetts, USA, was compared. Antimicrobial susceptibility tested using Kirby–Bauer disk diffusion with seven agents. A high proportion agent-resistant E. isolates (59.2%) were detected samples compared a lower 17.5% feces....
Metacommunity theory generally predicts that regional dispersal of organisms among local habitat patches should influence spatial patterns species diversity. In particular, increased rates are expected to increase (alpha) diversity, yet homogenize communities across the region (decreasing beta-diversity), resulting in no change (gamma) Although effect on alpha-diversity has garnered much experimental attention, diversity at larger scales (beta and gamma) is poorly understood. Furthermore,...
American crow (Corvus brachyrhynchos) faeces were tested for Escherichia coli with plasmid-mediated quinolone resistance (PMQR), extended-spectrum beta-lactamases (ESBL) and AmpC beta-lactamases. A total of 590 faecal samples collected at four roosting sites in the USA cultivated on selective media. Pulsed-field gel electrophoresis (PFGE) multi-locus sequence typing (MLST) performed to assess clonality. Transferability genes was studied using conjugation transformation bioassays. In total,...
Introductory paragraph The SARS-CoV-2 pandemic likely began by viral spillover from animals to humans 1-3 ; today multiple animal species are known be susceptible infection 4-8 . White-tailed deer, Odocoileus virginianus infected in North America at substantial levels 9-11 , and genomic data suggests that a variant deer may have spilled back 12,13 Here we characterize Pennsylvania (PA) sampled during fall winter 2021. Of 123 nasal swab samples analyzed RT-qPCR, 20 (16.3%) were positive for...
Limited physical activity, sedentary behavior, and reduction in muscle mass, strength, function are accompanied by negative outcomes. The relationship between these factors mental health-related quality of life (HRQoL) has yet to be elucidated continuing care retirement community (CCRC) residents. current study investigated the relationships among HRQoL. A sample 105 CCRC residents participated this cross-sectional correlational study. Findings demonstrated that low activity were...
