Atlantic Coastal

Atlantic Coastal Plain Flora (ACPF) are a group of plants mostly inhabiting lakeshores along the Atlantic coast of the United States, with disjunct populations in Nova Scotia and Ontario. To better define their ecological requirements, the main objective of this study was to determine the factors (biotic and abiotic habitat components) influencing ACPF communities (distribution, species abundance, and richness) at both the landscape and local scales. On 16 lakeshores in southwestern Nova Scotia, we characterized ACPF communities and habitat within 20 cm square contiguous quadrats distributed along 20 m transects (landscape scale) and in 5 m × 5 m grids (local scale). Performing redundancy analysis (n = 16 transects), we found that at the landscape scale, shoreline slope and shrub species distribution influenced the quantity of suitable habitat available for ACPF, with mineral shorelines supporting higher ACPF richness. Using spatial generalized linear mixed models (n = 3125 quadrats in five grids), we found that elevation, vegetation elements (shrubs, sundews, graminoids), and substrate type mostly influenced ACPF presence and abundance. ACPF also showed inter-specific differences in habitat preferences. Defining ACPF ecological requirements at both the landscape and local scales is important to guide conservation and management actions in Nova Scotia and throughout their North American range.

Productivity Estimate

An estimate of productivity for a southwestern Nova Scotia Laminaria community was obtained using a dynamic simulation model which incorporated data on population recruitment and mortality, lamina growth and attrition, and interspecific competition for L. longicruris and L. digitata. The estimate for the total quantity of particulate material produced by this community at equilibrium is ≈6800 g∙m−2∙yr−1 (wet weight), or ≈408 g C∙m−2∙yr−1. The annual productivity to standing crop ratio (P:S) was determined to be ≈2.1:1. The productivity estimate for this community at equilibrium is considerably lower than a widely cited previous estimate for Laminaria productivity in Nova Scotia, which placed the seaweed zone amongst the most productive plant communities known. An evaluation of the methodology yielding this estimate has indicated that inaccurate estimates of population age structure and mortality have possibly resulted in a significant overestimation of particulate productivity.

During August and September 2010, we surveyed the entire 20.4 km perimeter of Brier Island, Nova Scotia, for the invasive shrub Rosa rugosa (Rugosa Rose). This island in the outer reaches of the Bay of Fundy of Nova Scotia is geographically isolated and relatively undeveloped. Our objective was to determine the extent and mechanism of the invasion of R. rugosa into different coastal habitats to gain insight into the potential threat to native biodiversity from the unchecked population growth of this monopolizing, rank shrub. Over 300 colonies of R. rugosa with mean height over 1 m occupied 2089 m of the island perimeter within 10 m of the top of the beach. The mean distance between colonies was about 61 m and the maximum distance was 1927 m. At least 33 colonies formed almost impenetrable walls, each over 10 m in length, and 2 colonies occupied about 500 m2 each. Rosa rugosa had greatest density on a sand–gravel beach on which 88 colonies occupied 22% of the area and 33% of the beach margin. Exponential growth of the population (inferred from aerial photographs from 1970, 1988, and 2000) may be due to the various systems of seed dispersal. Agents include primary (American Mink, Neovison vison, and Red Squirrel, Tamiascurius hudsonicus) and secondary (an unidentified rodent) biotic dispersers. Longer distance dispersal may include Coyotes (Canis latrans), off-road vehicles and deposition of fruits by currents and waves. The main sites of seedling establishment are native habitats, such as dune grass and seashore Seaside Plantain (Plantago maritima) zones, albeit modified by this exotic rose. Dispersal of colonies contradicts a hypothesis of dispersal from human habitation along roads and tracks to the coastal habitats. We conclude that R. rugosa is having a significant impact on marine coastal plant communities and has the potential to dominate windswept shrub habitats on coastlines of much of Nova Scotia.
