Erratum to: Estimates of vital rates for a declining loggerhead turtle (Caretta caretta) subpopulation: implications for management Erratum to: Estimates of vital rates for a declining loggerhead turtle (Caretta caretta) subpopulation: implications for management
Erratum to: Mar Biol (2014) 161:2659–2668 DOI 10.1007/s00227-014-2537-0 The Open Robust Model methods used for analysis in this study were developed by Kendall and Bjorkland (2001) and Kendall (2010). The language used in this manuscript to describe formatting and implementation of data for these analyses was derived heavily from Phillips et al. (2014). Therefore, the wording in the last...

Multilevel learning in the adaptive management of waterfowl harvests: 20 years and counting Multilevel learning in the adaptive management of waterfowl harvests: 20 years and counting
In 1995, the U.S. Fish and Wildlife Service implemented an adaptive harvest management program (AHM) for the sport harvest of midcontinent mallards (Anas platyrhynchos). The program has been successful in reducing long-standing contentiousness in the regulatory process, while integrating science and policy in a coherent, rigorous, and transparent fashion. After 20 years, much has been...

Modelling the effects of seasonality and socioeconomic impact on the transmission of Rift Valley fever virus Modelling the effects of seasonality and socioeconomic impact on the transmission of Rift Valley fever virus
Rift Valley fever (RVF) is an important mosquito-borne viral zoonosis in Africa and the Middle East that causes human deaths and significant economic losses due to huge incidences of death and abortion among infected livestock. Outbreaks of RVF are sporadic and associated with both seasonal and socioeconomic effects. Here we propose an almost periodic three-patch model to investigate the

Global change and conservation triage on National Wildlife Refuges Global change and conservation triage on National Wildlife Refuges
National Wildlife Refuges (NWRs) in the United States play an important role in the adaptation of social-ecological systems to climate change, land-use change, and other global-change processes. Coastal refuges are already experiencing threats from sea-level rise and other change processes that are largely beyond their ability to influence, while at the same time facing tighter budgets...

Optimization and resilience in natural resources management Optimization and resilience in natural resources management
We consider the putative tradeoff between optimization and resilience in the management of natural resources, using a framework that incorporates different sources of uncertainty that are common in natural resources management. We address one-time decisions, and then expand the decision context to the more complex problem of iterative decision making. For both cases we focus on two key...

The Gulf Coast Vulnerability Assessment: Mangrove, Tidal Emergent Marsh, Barrier Islands, and Oyster Reef The Gulf Coast Vulnerability Assessment: Mangrove, Tidal Emergent Marsh, Barrier Islands, and Oyster Reef
Climate, sea level rise, and urbanization are undergoing unprecedented levels of combined change and are expected to have large effects on natural resources—particularly along the Gulf of Mexico coastline (Gulf Coast). Management decisions to address these effects (i.e., adaptation) require an understanding of the relative vulnerability of various resources to these stressors. To meet...

Dynamic reserve design in the face of climate change and urbanization Dynamic reserve design in the face of climate change and urbanization
Reserve design is a process that must address many ecological, social, and political factors to successfully identify parcels of land in need of protection to sustain wildlife populations and other natural resources. Making land acquisition choices for a large, terrestrial protected area is difficult because it occurs over a long timeframe and may involve consideration future conditions...

One carp, two carp: are there more carp in the Wailoa River? One carp, two carp: are there more carp in the Wailoa River?
The February, 2015 issue of Hawaii Fishing News included the annual list of Hawai`i records for the largest fish of various species caught in the state. Among the new records was one for a 15-pound grass carp (Ctenopharyngodon idella) caught by Avery Berido in the Wailoa River at Hilo on September 13, 2013. A photograph taken by Mr. Berido of the record grass carp garnered our attention...

Towards sustainable management of huntable migratory waterbirds in Europe Towards sustainable management of huntable migratory waterbirds in Europe
The EU Birds Directive and the African-Eurasian Waterbird Agreement provide an adequate legal framework for sustainable management of migratory waterbird populations. The main shortcoming of both instruments is that it leaves harvest decisions of a shared resource to individual Member States and Contracting Parties without providing a shared information base and mechanism to assess the...

Inferring spatial and temporal behavioral patterns of free-ranging manatees using saltwater sensors of telemetry tags Inferring spatial and temporal behavioral patterns of free-ranging manatees using saltwater sensors of telemetry tags
Diving or respiratory behavior in aquatic mammals can be used as an indicator of physiological activity and consequently, to infer behavioral patterns. Five Antillean manatees, Trichechus manatus manatus, were captured in Chetumal Bay and tagged with GPS tracking devices. The radios were equipped with a micropower saltwater sensor (SWS), which records the times when the tag assembly was...
