Maintaining amphibian populations in managed forests requires a balance between timber extraction and retaining functional connectivity for animals that use multiple vegetation types to satisfy habitat requirements, particularly where extensive harvesting may increase fragmentation. Quantifying dispersal patterns in response to harvest, especially across high-contrast edges adjacent to unlogged forest, is critical for evaluating the effects of harvest configuration on amphibians. We tested the initial post-metamorphic orientation of juvenile wood frogs (Lithobates sylvaticus) at edges in harvests (31– 60% retention standwide) in the Acadian forest of Maine, USA, during the period when juveniles emigrate from breeding pools. We released juveniles (n …
The Effects Of Rotation And River Discharge On Net Mixing In Small-Mouth Kelvin Plumes, Kelly Cole, Robert D. Hetland
The Effects Of Rotation And River Discharge On Net Mixing In Small-Mouth Kelvin Plumes, Kelly Cole, Robert D. Hetland
Publications
Small-mouth Kelvin number plumes, or plumes with a source width smaller than the deformation radius, are characterized by near-field plume regions of rapid lateral expansion and strong vertical mixing. Net plume mixing, or the dilution of a plume by ocean water between the estuary mouth and the far-field plume, is examined using idealized numerical experiments with the Regional Ocean Modeling System (ROMS). The density anomaly of plume water entering the far field is determined from isohaline analysis of the modeled salinity field. The experiments indicate that when estuarine discharge increases, net plume mixing decreases in a rotating environment but increases …

Modeling Spatiotemporal Variability Of The Bioclimate Envelope Of Homarus Americanus In The Coastal Waters Of Maine And New Hampshire, Kisei Tananka, Yong Chen

A bioclimate envelope model was developed to evaluate the potential impacts of climate variability on American lobster (Homarus americanus). Bioclimate envelopes were defined by season-, sex-, and stage- specific Habitat Suitability Indices (HSI) based on (1) bottom temperature, (2) bottom salinity, and (3) depth. The species’ association to each of these three environmental attributes was expressed using Suitability Indices (SIs) calibrated by standardized lobster abundance derived from 14 years of fishery independent survey. A regional ocean model (Finite-Volume Community Ocean Model) was integrated with the HSI to hindcast spatiotemporal variability of bioclimate envelopes for American lobster in coastal waters of …

Why Rhetoric Matters For Ecology, Caroline Druschke, Bridie Mcgreavy

Increasingly, scientists and funding agencies such as the US National Science Foundation are recognizing the need for better science communication and more effective broader impacts activities. Compelled to make research more relevant to public stakeholders and policy makers, researchers look for ways to gain the necessary skillset to move their science from the field and laboratory into public forums. We suggest that the ancient discipline of rhetoric provides a useful – and underutilized – path forward. Building from the fundamental connections between ecology and rhetoric and drawing from practical examples at the intersection of these two fields, we demonstrate how …
