The Northern Goshawk ( Accipiter gentilis) is a large forest raptor with a Holarctic distribution and, in some portions of its range, a species of conservation concern. To augment previously reported genetic markers, 13 novel polymorphic microsatellite markers were developed to establish individual identification and familial relationships, to assess levels of genetic diversity, and to identify diagnostic markers. Of the 22 loci tested, 13 were polymorphic, seven were monomorphic, and two failed to amplify. This suite of microsatellite loci yielded a combined probability of parental exclusion of 98%; a single individual sampled from a North American population can be reliably identified using a combination of seven of the 13 polymorphic loci. Cross-species screening in Cooper's Hawks (A. cooperii) and Sharp-shinned Hawks (A. striatus) of the 20 loci that successfully amplified in Northern Goshawks identified 13 loci as polymorphic in each species. Six of these loci (Age1303, Age1308, Age1309, Age1312, and Age1314) appeared to be useful in distinguishing between Accipiter species. These markers will be useful to researchers investigating populations of North American accipiters.

AbstractAccurate knowledge of geographic ranges and genetic relationships among populations is important when managing a species or population of conservation concern. In the western Canadian province of British Columbia, a subspecies of the northern goshawk (Accipiter gentilis laingi) is designated as Threatened under the Canadian Species at Risk Act. Historically, the range of this bird of prey has been ambiguous and its genetic distinctness from the other North American subspecies (Accipiter gentilis atricapillus) has not been well established. Given the uncertainty in using morphological traits to assign individual goshawks to these two subspecies, we analyzed genomic relationships in tens of thousands of single nucleotide polymorphisms identified using genotyping-bysequencing of high-quality genetic samples. This genome-wide analysis revealed a genetically distinct population of northern goshawks on the archipelago of Haida Gwaii and subtle genetic structuring among the remainder of our sampling sites within North America. Following from this analysis, we developed targeted genotyping assays for ten loci that are highly differentiated between the two main genetic clusters, allowing the addition of hundreds of low-quality samples to our analysis. This additional information confirmed that the distinct genetic cluster on Haida Gwaii is restricted to that archipelago. As the laingi form was originally described as being based in Haida Gwaii, where the type specimen of that form is from, further study (especially of morphological traits) may indicate a need to restrict this name to the Haida Gwaii genetic cluster. Regardless of taxonomic treatment, our finding of a distinct Haida Gwaii genetic cluster along with the small and historically declining population size of the Haida Gwaii population suggests a high risk of extinction of an ecologically and genetically distinct form of northern goshawk. Outside of Haida Gwaii, sampling regions along the coast of BC and southeast Alaska (often considered regions inhabited by laingi) show some subtle differentiation from other North American regions. We anticipate that these results will increase the effectiveness of conservation management of northern goshawks in northwestern North America. More broadly, other conservation-related studies of genetic variation may benefit from the two-step approach we employed that first surveys genomic variation using high-quality samples and then genotypes low-quality samples at particularly informative loci.

Abstract In December 1999, an exceptional windstorm traveled across northern France (Côte d'Or). The severity of the stand damages ranged from <1 to >80%, and over 10% of the overall surface of several homogeneous woodlands (from ∼1,000 to 8,000 ha) was affected by the windstorm. Data were available on Northern Goshawk (Accipiter gentilis) density, productivity, and nesting stand preferences in that area before the disturbance. The species showed tolerance to the natural disturbance induced by the windstorm: we found no difference in density, nesting stand choice, or productivity between the six breeding seasons before the windthrow and in the one immediately after. Breeding pairs moved away (50–200 m) from their traditional nest stand only when its original structure was altered by >30% in the 50 m surrounding the nest tree. We hypothesize that the Northern Goshawk tolerance to windstorm damage may be the result of an adaptive response, which they have developed under both climate- and human-originated stresses.

AbstractThe phylogenetic placement of the North American band-winged grasshopper Shotwellia isleta (Gurney 1940) (Orthoptera: Acrididae: Oedipodinae) has been investigated. This rare and unique species of grasshopper belongs to a monotypic genus known only from a few isolated locations in the Chihuahuan Desert of Mexico and New Mexico, USA. The taxonomic status of Shotwellia has been uncertain and historically classified in very different ways relative to other genera. We conducted the first molecular phylogenetic cladistic analysis of Shotwellia and of the Chortophaga (Saussure) genus group in which it is currently classified, using three mitochondrial genes (16S, 12S and cytochrome c oxidase II), 14 morphological characters and two behavioral characters. Our analysis supports the current monotypic status of the genus Shotwellia within the Chortophaga genus group and indicates that Shotwellia is sister to the other genera in that group. Shotwellia isleta is a species of conservation concern, and our field sampling indicates that it is a rare specialist of freshwater ephemeral desert lake beds that are being impacted by human activity. Understanding the phylogeny of S. isleta provides a basis from which biological, evolutionary and conservation inferences can be made.

By 2040, roughly two-thirds of humanity are expected to live in urban areas. As cities expand, humans irreversibly transform natural ecosystems, creating both opportunities and challenges for wildlife. Here, we investigate how the Northern Goshawk ( Accipiter gentilis ) is adjusting to urban environments. We measured a variety of behavioural and ecological parameters in three urban and four rural study sites. City life appeared related to all parameters we measured. Urban female goshawks were overall 21.7 (CI 95% 5.13–130) times more likely to defend their nestlings from humans than rural females. Urban goshawks were 3.64 (CI 95% 2.05–6.66) times more likely to feed on pigeons and had diets exhibiting lower overall species richness and diversity. Urban females laid eggs 12.5 (CI 95% 7.12–17.4) days earlier than rural individuals and were 2.22 (CI 95% 0.984–4.73) times more likely to produce a brood of more than three nestlings. Nonetheless, urban goshawks suffered more from infections with the parasite Trichomonas gallinae , which was the second most common cause of mortality (14.6%), after collisions with windows (33.1%). In conclusion, although city life is associated with significant risks, goshawks appear to thrive in some urban environments, most likely as a result of high local availability of profitable pigeon prey. We conclude that the Northern Goshawk can be classified as an urban exploiter in parts of its distribution.

A hypothesized evolutionary history of the North American endemic trichiine scarab genusTrichiotinusis presented including all eight species and three outgroup taxa. Data from nineteen morphological traits and CO1 and 28S gene sequences were used to construct phylogenies using both parsimony and Bayesian algorithms. All results show thatTrichiotinusis monophyletic. The best supported topology shows that the basal speciesT. lunulatusis sister to the remaining taxa that form two clades, with four and three species each. The distribution of one lineage is relatively northern while the other is generally more southern. The ancestralTrichiotinuslineage arose from 23.8–14.9 mya, and east-west geographic partitioning of ancestral populations likely resulted in cladogenesis and new species creation, beginning as early as 10.6–6.2 mya and as recently as 1.2–0.7 mya. Morphological character evolution is also briefly discussed. The limited distribution ofT. rufobrunneusin Florida andT. viridansin the Midwest mainly due to urban development and widespread agriculture makes these two species of conservation concern.

Abstract Background White-nose Syndrome (WNS) has reduced the abundance of many bat species within the United States’ Mid-Atlantic region. To determine changes within the National Park Service National Capital Region (NCR) bat communities, we surveyed the area with mist netting and active acoustic sampling (2016–2018) and compared findings to pre-WNS (2003–2004) data. Results The results indicated the continued presence of the threatened Myotis septentrionalis (Northern Long-eared bat) and species of conservation concern, including Perimyotis subflavus (Tri-colored bat), Myotis leibii (Eastern Small-footed bat) and Myotis lucifugus (Little Brown bat). However, we documented a significant reduction in the abundance and distribution of M. lucifugus and P. subflavus, a decrease in the distribution of M. septentrionalis, and an increase in the abundance of Eptesicus fuscus (Big Brown bat). Conclusions Documented post-WNS M. septentrionalis recruitment suggests that portions of the NCR may be important bat conservation areas. Decreases in distribution and abundance of P. subflavus and M. lucifugus indicate probable extirpation from many previously occupied portions of the region.
