The Dartmouth, Sawmill River 4000 acre watershed forms part of North America’s only urban core boreal watershed within a population base in excess of 400,000 people (Halifax Regional Municipality) where the inner city lakes have not eutrophied and retain oxic lake bottoms for an average of 10 months/year up to temperatures ranging from 21-23 degrees Celsius. BARA sees this native capacity of our glacial till clay bottomed lakes to adsorb phosphorous as worth preserving within an urban core densified mixed residential, commercial and industrial landscape. The baseline monitoring forming this Dataset is intended to create graphic imaging of the correlation of the seasonal anoxia and specific/conductance to infer rate of internal loading levels as the iron and manganese flush phosphates from the glacial till lake bottom soils into the water column, and estimate a predictive index of water temperatures correlated to seasonal anoxia levels for lakes monitored. Recent history over the past four decades is 8 to 15 mg/L total phosphorous. BARA hopes the scientific talents of the local Marine Biologists from federal Department of Fisheries and Oceans (DFO), the Bedford Institute of Oceanography (BIO), local universities and Community College combine with the recreational and professional sport history of our lakes as the birthplace of Hockey, Starr Skates, and an active world class canoe, kayak and paddling race course, for the basis of modeling to all other North American boreal urban watersheds that seek to restore pre-industrial sustainable phosphate load modelling to their water courses. Of the 9 lakes monitored, BARA has partnered with and thanks Crombie REIT, HRM District #5, Gloria McCluskey, and Nova Scotia Sport Fisheries for funding to install a self-contained solar powered Aerator to improve fish habitat by reducing seasonal anoxia in the 4 hectare Lake Penhorn, by lowering the hypolimnion to near lake bottom, and supporting decomposition of lake bottom organics.

Genetic diversity is essential for populations to adapt to changing environments. Measures of genetic diversity are often based on selectively neutral markers, such as microsatellites. Genetic diversity to guide conservation management, however, is better reflected by adaptive markers, including genes of the major histocompatibility complex (MHC). Our aim was to assess MHC and neutral genetic diversity in two contrasting bottlenose dolphin (Tursiops aduncus) populations in Western Australia—one apparently viable population with high reproductive output (Shark Bay) and one with lower reproductive output that was forecast to decline (Bunbury). We assessed genetic variation in the two populations by sequencing the MHC class II DQB, which encompasses the functionally important peptide binding regions (PBR). Neutral genetic diversity was assessed by genotyping twenty‐three microsatellite loci.
We confirmed that MHC is an adaptive marker in both populations. Overall, the Shark Bay population exhibited greater MHC diversity than the Bunbury population—for example, it displayed greater MHC nucleotide diversity. In contrast, the difference in microsatellite diversity between the two populations was comparatively low.
Our findings are consistent with the hypothesis that viable populations typically display greater genetic diversity than less viable populations. The results also suggest that MHC variation is more closely associated with population viability than neutral genetic variation. Although the inferences from our findings are limited, because we only compared two populations, our results add to a growing number of studies that highlight the usefulness of MHC as a potentially suitable genetic marker for animal conservation. The Shark Bay population, which carries greater adaptive genetic diversity than the Bunbury population, is thus likely more robust to natural or human‐induced changes to the coastal ecosystem it inhabits.

Le bassin versant de 4 000 acres de Dartmouth et de la rivière Sawmill fait partie du seul bassin hydrographique boréal urbain d'Amérique du Nord comptant une population de plus de 400 000 habitants (municipalité régionale d'Halifax) où les lacs du centre-ville ne se sont pas eutrophiés et conservent leur fond oxique en moyenne 10 mois par an, jusqu'à des températures allant de 21 à 23 degrés Celsius. La BARA considère que cette capacité naturelle de nos lacs à fond argileux à adsorber le phosphore mérite d'être préservée dans un paysage résidentiel, commercial et industriel densifié en milieu urbain. La surveillance de base constituant cet ensemble de données vise à créer une imagerie graphique de la corrélation entre l'anoxie saisonnière et la spécificité/conductance afin de déduire le taux des niveaux de charge interne lorsque le fer et le manganèse expulsent les phosphates des sols glaciaires du fond des lacs dans la colonne d'eau, et d'estimer un indice prédictif des températures de l'eau corrélé aux niveaux d'anoxie saisonniers pour les lacs surveillés. L'évolution récente des quarante dernières années indique que la teneur totale en phosphore est comprise entre 8 et 15 mg/L. La BARA espère que les talents scientifiques des biologistes marins locaux du ministère fédéral des Pêches et des Océans (MPO), de l'Institut océanographique de Bedford (BIO), des universités locales et du Community College se combineront à l'histoire des sports récréatifs et professionnels de nos lacs, berceau du hockey, Starr Skates et d'un parcours de course actif de canot, de kayak et de pagayage de classe mondiale, afin de s'inspirer de tous les autres bassins hydrographiques urbains boréaux d'Amérique du Nord qui cherchent à rétablir la modélisation préindustrielle durable de la charge de phosphate dans leurs cours d'eau. Parmi les 9 lacs surveillés, la BARA s'est associée à Crombie REIT, HRM District #5, Gloria McCluskey et Nova Scotia Sport Fisheries pour le financement de l'installation d'un aérateur solaire autonome afin d'améliorer l'habitat des poissons en réduisant l'anoxie saisonnière dans les 4 hectares du lac Penhorn, en abaissant l'hypolimnion près du fond du lac et en favorisant la décomposition des matières organiques du fond du lac.
