North-facing slopes and elevation shape asymmetric genetic structure in the range-restricted salamander Plethodon shenandoah

Species with narrow environmental preferences are often distributed across fragmented patches of suitable habitat, and dispersal among subpopulations can be difficult to directly observe. Genetic data collected at population centers can help quantify gene flow, which is especially important for vulnerable species with a disjunct range. Plethodon...

Eastern Carpenter Bee (Hymenoptera: Apidae): Nest structure, nest cell provisions, and trap nest acceptance in Rhode Island

Analysis of pollen provisions in Xylocopa virginica (L.) nests in southern Rhode Island showed that this species produced pollen loaves from 21 different genera of plants in 2016, 19 in 2017, and 39 in 2018. Antirrhinium majus L. (garden snapdragon) pollen was the most common type collected in all three years (21.4%). Overall,...

Annual survival, site fidelity, and longevity in the eastern coastal population of the Painted Bunting (Passerina ciris) based on a 20-year mark-recapture/resighting study

A long-term study of annual survival, longevity, and site fidelity in the eastern coastal population of the Painted Bunting (Passerina ciris) during the breeding season was conducted from 1999 through 2018 in the outer coastal plain of the southeastern Atlantic coast of the United States. Painted Buntings were uniquely color-banded from 1999...

Future directions to escalate benefits of stepping-stone approach for conservation translocations

Through a reintroduction case study on the critically endangered Vancouver Island marmot (Marmota vancouverensis), we introduced a ‘stepping-stone’ approach which utilizes the transition of released individuals among populations to maximize demographic growth potential (Lloyd et al. 2019). We greatly appreciate and hereby reflect on the...

Pathways to strategic communication for biodiversity conservation: Response to “Hearing ourselves (and acting in consequence): A commentary on Bekessy et al. from a bird-handling environmental education perspective”

Central to discussions about the merits of ecosystem services as a communication strategy is the degree to which it represents a strategic and effective approach to advance biodiversity conservation. There is increasing recognition that many conservation communication efforts can be more strategic (e.g. Kusmanoff et al. 2016).

Functional variation at an expressed MHC class IIß locus associates with Ranavirus infection intensity in larval anuran populations

Infectious diseases are causing catastrophic losses to biodiversity globally. Iridoviruses in the genus Ranavirus are among the leading causes of amphibian disease-related mortality. Polymorphisms in major histocompatibility complex (MHC) genes are significantly associated with variation in amphibian susceptibility to pathogens. MHC genes encode...

Using the value of information to improve conservation decision making

Conservation decisions are challenging, not only because they often involve difficult conflicts among outcomes that people value, but because our understanding of the natural world and our effects on it is fraught with uncertainty. Value of Information (VoI) methods provide an approach for understanding and managing uncertainty from the standpoint...

The contribution of road-based citizen science to the conservation of pond-breeding amphibians

Roadside amphibian citizen science (CS) programmes bring together volunteers focused on collecting scientific data while working to mitigate population declines by reducing road mortality of pond‐breeding amphibians. Despite the international popularity of these movement‐based, roadside conservation efforts (i.e. “big nights,” “bucket brigades”...

Pheno forecasts predict seasonal activity of pest and invasive species to support decision making

The USA National Phenology Network’s Pheno Forecast maps indicate the status of insect pest or invasive plant life cycle stages in real time across the contiguous United States. This information can guide when to monitor or to undertake management activities. These maps, available at 2.5 km spatial resolution, are updated daily and are available...

Confronting uncertainty: Contributions of the wildlife profession to the broader scientific community

Most wildlife professionals are engaged in 1 or both of 2 basic endeavors: science and management. These endeavors are a focus of many other disciplines, leading to widespread sharing of general methodologies. Wildlife professionals have appropriately borrowed and assimilated many methods developed primarily in other disciplines but have also led...

Scale‐dependent effects of isolation on seasonal patch colonisation by two Neotropical freshwater fishes

The metapopulation paradigm has been central to improve the conservation and management of natural populations. However, despite the large number of studies on metapopulation dynamics, the overall support for the relationships on which the paradigm is based has not been strong. Here, we studied the occupancy dynamics of two Neotropical fishes (i.e...

Disease‐structured N‐mixture models: A practical guide to model disease dynamics using count data

Obtaining inferences on disease dynamics (e.g., host population size, pathogen prevalence, transmission rate, host survival probability) typically requires marking and tracking individuals over time. While multistate mark–recapture models can produce high‐quality inference, these techniques are difficult to employ at large spatial and long...
