In fisheries management, understanding anthropogenic impacts on fish population genetic structure is essential because genetic diversity is a fundamental attribute contributing to a species’ evolutionary capacity. An extended history of supplemental stocking has led to the introgression of genes from non-local, hatchery-reared brook trout (Salvalinus fontinalis) into natural Adirondack populations in the state of New York. Managers have therefore gone to great lengths to protect known or suspected pristine “heritage” populations, but the genetic integrity of most populations is unknown. We used 11 microsatellite loci to examine a putative, but as yet unconfirmed “heritage” population in Dix Pond (Essex County, New York), in an effort to confirm its genetic uniqueness, quantify genetic diversity, and determine the geographic extent of the population. No spatial population structure was found within the Dix Pond/Elk Lake watershed, with minimal signs of introgression from historical stocking. The Dix/Elk population showed allelic richness, and effective population size comparable to the highest diversity heritage population among the four that we used for comparison. These patterns support continued heritage status for the Dix Pond population and recognition of the entire Dix-Elk watershed as habitat for this strain. We conclude this study by discussing how the genetic techniques employed here may help to inform future management decisions associated with the conservation and protection of imperiled populations throughout the globe.

With this contribution, we report on the continued and rapid spread of Hemimysis anomala (Crustacea, Mysidae) to inland waters of New York State within the Laurentian Great Lakes watershed. In the spring and summer of 2010, we detected Hemimysis at multiple locations in Seneca Lake, spanning the lake's 61 km length, and in the Seneca-Cayuga Canal, 7 km downstream of the canal's source at Seneca Lake. We did not detect Hemimysis in any of the other ten Finger Lakes. The pattern of range expansion suggests jump dispersal to Seneca Lake, followed by passive dispersal in the Seneca-Cayuga Canal. This range expansion highlights the potential of this emerging invader to spread throughout the New York State Canal system that links the Great Lakes with the Hudson River watershed and a number of large inland lakes via the Erie Canal and its tributaries. During our nighttime sampling campaign on Seneca Lake, densities of Hemimysis exceeding 2500 ind./m3 were associated with littoral rocky structures, docks, and piers. At a reference site near the source of the Seneca-Cayuga Canal, we observed demographic shifts from an adult-dominated population in early spring to a juvenile-dominated population from late-spring to autumn. We also observed strong nocturnal behavior for all stages, with juveniles rising earlier than adults in the evening and remaining higher in the water column near dawn. These demographic and behavioral characteristics, combined with the extensive hydrogeographic network in the Great Lakes, contribute to the species rapid range expansion and the mechanism of its spread.

Kinkajou social groups generally consist of one adult female, two males, one subadult and one juvenile. Based on analysis of variation in 11 microsatellite loci, we assess the degree of kinship within and between four social groups totaling 25 kinkajous. We use exclusion and likelihood analyses to assign parents for seven of the eight offspring sampled, five with ≥ 95% certainty, and two with ≥ 80% certainty. Five of six identified sires of group offspring came from the same social group as the mother and pup. Adult males and females within a group were unrelated and subadults and juveniles were offspring of the group adults, suggesting a family structure. All five identified paternities within a social group were by the dominant male of the group. However, this copulation asymmetry does not necessarily reflect cooperation due to kinship ties between the two adult males within a group as one of two adult male pairs sampled was unrelated. Neighbouring male kinkajous were more closely related to each other than neighbouring female kinkajous, suggesting that females disperse more often or farther than males.

Bryophyte and vascular plant fragments were obtained from late-spring snowbeds at three localities in the Adirondack Mountains, New York. Fragment diversity in samples at alpine and krummholz sites far exceeded that at a forested site, and the diversity of bryophyte species represented by the fragments surpassed that of vascular plants. Approximately 82% of all bryophyte fragments found were in sufficiently good condition to permit identification to species or genus. Statistically significant differences in fragment species diversity occurred between the alpine sites and the forested site, but not between the two alpine sites. The consistent presence of liverworts in the alpine samples indicates that their absence from late-glacial sediments may be due more to taphonomy than either an absence of hepatics from the late-glacial flora or an inability of hepatics to disperse by gametophyte fragments. We detected only a few allochthonous fragments in our samples, and these were of bryophyte species characteristic of lower elevation balsam fir and red spruce-balsam fir forests. In alpine tundra, winter-dispersed fragments of bryophytes may serve as vegetative diaspores, providing a mechanism for rapid establishment of new populations every year following snow melt.
