StreamThermal: A software package for calculating thermal metrics from stream temperature data StreamThermal: A software package for calculating thermal metrics from stream temperature data
Improving quality and better availability of continuous stream temperature data allows natural resource managers, particularly in fisheries, to understand associations between different characteristics of stream thermal regimes and stream fishes. However, there is no convenient tool to efficiently characterize multiple metrics reflecting stream thermal regimes with the increasing amount...

Effects of salinity and flooding on post-hurricane regeneration potential in coastal wetland vegetation Effects of salinity and flooding on post-hurricane regeneration potential in coastal wetland vegetation
PREMISE OF THE STUDY: The nature of regeneration dynamics after hurricane flooding and salinity intrusion may play an important role in shaping coastal vegetation patterns. METHODS: The regeneration potentials of coastal species, types and gradients (wetland types from seaward to landward) were studied on the Delmarva Peninsula after Hurricane Sandy using seed bank assays to examine...

U.S. Geological Survey science strategy for highly pathogenic avian influenza in wildlife and the environment (2016–2020) U.S. Geological Survey science strategy for highly pathogenic avian influenza in wildlife and the environment (2016–2020)
Introduction Through the Science Strategy for Highly Pathogenic Avian Influenza (HPAI) in Wildlife and the Environment, the USGS will assess avian influenza (AI) dynamics in an ecological context to inform decisions made by resource managers and policymakers from the local to national level. Through collection of unbiased scientific information on the ecology of AI viruses and wildlife...

Book review: Black bass diversity: Multidisciplinary science for conservation Book review: Black bass diversity: Multidisciplinary science for conservation
These proceedings are from the third symposium dedicated to management and conservation of black basses in the genus Micropterus. The first symposium was held in 1975 (R. H. Stroud and H. Clepper. Black Bass Biology and Management. Washington (DC): Sport Fishing Institute) followed 25 years later by Black Bass 2000 (D. P. Philipp and M. S. Ridgway. 2002. Black Bass: Ecology, Conservation...

Inter-annual variability of area-scaled gaseous carbon emissions from wetland soils in the Liaohe Delta, China Inter-annual variability of area-scaled gaseous carbon emissions from wetland soils in the Liaohe Delta, China
Global management of wetlands to suppress greenhouse gas (GHG) emissions, facilitate carbon (C) sequestration, and reduce atmospheric CO2 concentrations while simultaneously promoting agricultural gains is paramount. However, studies that relate variability in CO2 and CH4 emissions at large spatial scales are limited. We investigated three-year emissions of soil CO2 and CH4 from the...

Early life history and spatiotemporal changes in distribution of the rediscovered Suwannee moccasinshell Medionidus walkeri (Bivalvia: Unionidae) Early life history and spatiotemporal changes in distribution of the rediscovered Suwannee moccasinshell Medionidus walkeri (Bivalvia: Unionidae)
Accurate distribution data are critical to the development of conservation and management strategies for imperiled species, particularly for narrow endemics with life history traits that make them vulnerable to extinction. Medionidus walkeri is a rare freshwater mussel endemic to the Suwannee River Basin in southeastern North America. This species was rediscovered in 2012 after a 16-year...

Broken connections of wetland cultural knowledge Broken connections of wetland cultural knowledge
As global agriculture intensifies, cultural knowledge of wetland utilization has eroded as natural resources become more stressed, and marginal farmers move away from the land. The excellent paper by Fawzi et al. (2016) documents a particularly poignant case of traditional knowledge loss among the Marsh Arab women of Iraq. Through interviews, the authors document the breakdown of skill...

Ectoparasitism on deep-sea fishes in the western North Atlantic: In situ observations from ROV surveys Ectoparasitism on deep-sea fishes in the western North Atlantic: In situ observations from ROV surveys
A complete understanding of how parasites influence marine ecosystem functioning requires characterizing a broad range of parasite-host interactions while determining the effects of parasitism in a variety of habitats. In deep-sea fishes, the prevalence of parasitism remains poorly understood. Knowledge of ectoparasitism, in particular, is limited because collection methods often cause...

Barriers to and opportunities for landward migration of coastal wetlands with sea-level rise Barriers to and opportunities for landward migration of coastal wetlands with sea-level rise
In the 21st century, accelerated sea-level rise and continued coastal development are expected to greatly alter coastal landscapes across the globe. Historically, many coastal ecosystems have responded to sea-level fluctuations via horizontal and vertical movement on the landscape. However, anthropogenic activities, including urbanization and the construction of flood-prevention...

Measuring, interpreting, and responding to changes in coral reefs: A challenge for biologists, geologist, and managers Measuring, interpreting, and responding to changes in coral reefs: A challenge for biologists, geologist, and managers
What, exactly, is a coral reef? And how have the world’s reefs changed in the last several decades? What are the stressors undermining reef structure and function? Given the predicted effects of climate change, do reefs have a future? Is it possible to “manage” coral reefs for resilience? What can coral reef scientists contribute to improve protection and management of coral reefs? What...

Adaptive harvest management for the Svalbard population of pink‐footed geese: 2016 progress summary: Technical Report from DCE – Danish Centre for Environment and Energy, No. 86 Adaptive harvest management for the Svalbard population of pink‐footed geese: 2016 progress summary: Technical Report from DCE – Danish Centre for Environment and Energy, No. 86
This document describes progress to date on the development of an adaptive harvest management strategy for maintaining the Svalbard population of pink‐footed geese (Anser brachyrhynchus) near their agreed target level (60,000) by providing for sustainable harvests in Norway and Denmark. This report provides an assessment of the most recent monitoring information (1991-2015) and its...

Catalog of microscopic organisms of the Everglades, Part 1—The cyanobacteria Catalog of microscopic organisms of the Everglades, Part 1—The cyanobacteria
The microscopic organisms of the Everglades include numerous prokaryotic organisms, including the eubacteria, such as the cyanobacteria and non-photosynthetic bacteria, as well as several eukaryotic algae and protozoa that form the base of the food web. This report is part 1 in a series of reports that describe microscopic organisms encountered during the examination of several hundred...
