Informing research priorities for immature sea turtles through expert elicitation Informing research priorities for immature sea turtles through expert elicitation
Although sea turtles have received substantial focus worldwide, research on the immature life stages is still relatively limited. The latter is of particular importance, given that a large proportion of sea turtle populations comprises immature individuals. We set out to identify knowledge gaps and identify the main barriers hindering research in this field. We analyzed the perceptions...

Unusual foraging observations associated with seabird die-offs in Alaska Unusual foraging observations associated with seabird die-offs in Alaska
We report the first documentation of off-water foraging by the Fork-tailed Storm-Petrel Oceanodroma furcata and Short-tailed Shearwater Ardenna tenuirostris, a behavior not previously documented in any member of the families Hydrobatidae or Procellariidae. Over a two-week period in September 2016, we regularly observed individuals of these species over land on an extensive intertidal...

Genetic diversity, effective population size, and structure among black bear populations in the Lower Mississippi Alluvial Valley, USA Genetic diversity, effective population size, and structure among black bear populations in the Lower Mississippi Alluvial Valley, USA
Multiple small populations of American black bears Ursus americanus, including the recently delisted Louisiana black bear subspecies U. a. luteolus, occupy a fragmented landscape in the Lower Mississippi Alluvial Valley, USA (LMAV). Populations include bears native to the LMAV, bears translocated from Minnesota during the 1960s, and recently reintroduced and colonizing populations...

Synthesis Synthesis
Cranes have a close relationship with arable and pastoral agriculture that goes back hundreds, presumably thousands of years. The landscapes and ecoregions important to cranes are also those areas most conducive to agriculture. Thus, cranes and humans are attracted to the same landscapes and will therefore have futures that remain co-mingled. As such, agriculture can both benefit and...

Threats to cranes related to agriculture Threats to cranes related to agriculture
The greatest threats to cranes worldwide are related to agricultural activities. They include direct losses of wetlands or grasslands; altered wetland hydrology due to water control systems such as dams or irrigation ditches; fire; direct and indirect impacts from agricultural chemicals; human disturbances; disease risks where cranes congregate in high densities on crops or in...

Methods to reduce conflicts between cranes and farmers Methods to reduce conflicts between cranes and farmers
Alternative methods to reduce conflicts between cranes and farmers range from relatively simple, inexpensive disturbance methods to changes in land use at a landscape scale. Visual and acoustics disturbance methods can be useful for small fields or gardens but require frequent changes to prevent habituation by the cranes. Changes in farming practices can be implemented by individual...

Are hatchery-reared Rainbow Trout and Brown Trout effective predators on juvenile native fish? Are hatchery-reared Rainbow Trout and Brown Trout effective predators on juvenile native fish?
Hatchery‐reared Rainbow Trout Oncorhynchus mykiss and Brown Trout Salmo trutta are typically fed exclusively on commercially prepared pelleted feeds and have no experience catching or consuming live fish at the time of stocking. Despite this lack of predation experience, it is commonly assumed that stocked Rainbow Trout and Brown Trout will adversely impact native fish populations by...

Interactions and impacts of domesticated animals on cranes in agriculture Interactions and impacts of domesticated animals on cranes in agriculture
Affiliations of most cranes to humans and agriculture means they often interact with a variety of domestic animals. Those interactions can be beneficial or neutral when domestic animal densities and their impact on wetland or grassland systems are low to moderate, as found in more traditional agricultural practices. The most common interaction is with grazers, primarily domestic...

Observed climate change Observed climate change
As discussed in Chapter 1, climate is one of the principal factors that have determined the composition and extent of forest ecosystems in the Mid-Atlantic region during the past several thousand years. This chapter describes the climate trends in the assessment area that have been observed during the past century, including documented patterns of climate-related processes and extreme...

President's address for Wetland Science and Practice - October 2018 President's address for Wetland Science and Practice - October 2018
As 2018 moves into its last quarter, those of us in the southern U.S. check the skies for hurricanes, academics and students return to the classroom, and researchers wrap up the last of their year’s field work. For SWS, the last quarter brings new ways to promote internationalization...

Puerto Rico and the U.S. Virgin Islands Puerto Rico and the U.S. Virgin Islands
Average annual temperature for Puerto Rico and the U.S. Virgin Islands has increased by more than 1.5°F since 1950. Under a higher emissions pathway, historically unprecedented warming is projected by the end of the 21st century, including increases in extreme heat events. Future changes in total precipitation are uncertain, but extreme precipitation is projected to increase, with...
