Preparing for an uncertain future: Migrating shorebird response to past climatic fluctuations in the Prairie Potholes Preparing for an uncertain future: Migrating shorebird response to past climatic fluctuations in the Prairie Potholes
The Prairie Pothole Region, situated in the northern Great Plains, provides important stopover habitat for migratory shorebirds. During spring migration in the U.S. Prairie Potholes, 7.3 million shorebirds refuel in the region's myriad small, freshwater wetlands. Shorebirds use mudflats, shorelines, and ephemeral wetlands that are far more abundant in wet years than dry years. Generally...

The northern pike, a prized native but disastrous invasive: Chapter 14 The northern pike, a prized native but disastrous invasive: Chapter 14
As the chapters in this book describe, the northern pike Esox lucius Linneaus, 1758 is a fascinating fish that plays an important ecological role in structuring aquatic communities (chapter 8), has the capacity to aid lake restoration efforts (chapter 11), and contributes substantially to local economies, both as a highlysought after sport fish (chapter 12) and as a commercial fishing...

Resource competition model predicts zonation and increasing nutrient use efficiency along a wetland salinity gradient Resource competition model predicts zonation and increasing nutrient use efficiency along a wetland salinity gradient
A trade-off between competitive ability and stress tolerance has been hypothesized and empirically supported to explain the zonation of species across stress gradients for a number of systems. Since stress often reduces plant productivity, one might expect a pattern of decreasing productivity across the zones of the stress gradient. However, this pattern is often not observed in coastal...

Sirenian life history Sirenian life history
Sirenians, including the manatees and dugongs, are large herbivorous mammals that have evolved to an aquatic form since the Eocene epoch. Sirenians have unique adaptations, including dense bone for ballast and a longitudinal hemidiaphragm separating paired lungs (which aid in maintaining a horizontal posture in the water column), species-specific rostral deflection, and unique dentition...

The effect of isolation, fragmentation, and population bottlenecks on song structure of a Hawaiian honeycreeper The effect of isolation, fragmentation, and population bottlenecks on song structure of a Hawaiian honeycreeper
Little is known about how important social behaviors such as song vary within and among populations for any of the endemic Hawaiian honeycreepers. Habitat loss and non‐native diseases (e.g., avian malaria) have resulted in isolation and fragmentation of Hawaiian honeycreepers within primarily high elevation forests. In this study, we examined how isolation of Hawai'i ‘amakihi...

Validation of ATR FT-IR to identify polymers of plastic marine debris, including those ingested by marine organisms Validation of ATR FT-IR to identify polymers of plastic marine debris, including those ingested by marine organisms
Polymer identification of plastic marine debris can help identify its sources, degradation, and fate. We optimized and validated a fast, simple, and accessible technique, attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT-IR), to identify polymers contained in plastic ingested by sea turtles. Spectra of consumer good items with known resin identification codes...

Using expert knowledge to incorporate uncertainty in cause-of-death assignments for modeling of cause-specific mortality Using expert knowledge to incorporate uncertainty in cause-of-death assignments for modeling of cause-specific mortality
Implicit and explicit use of expert knowledge to inform ecological analyses is becoming increasingly common because it often represents the sole source of information in many circumstances. Thus, there is a need to develop statistical methods that explicitly incorporate expert knowledge, and can successfully leverage this information while properly accounting for associated uncertainty...

The migratory bird treaty and a century of waterfowl conservation The migratory bird treaty and a century of waterfowl conservation
In the final decades of the nineteenth century, concern was building about the status of migratory bird populations in North America. In this literature review, we describe how that concern led to a landmark conservation agreement in 1916, between the United States and Great Britain (on behalf of Canada) to conserve migratory birds shared by Canada and the United States. Drawing on...

Malassezia vespertilionis sp. nov.: A new cold-tolerant species of yeast isolated from bats Malassezia vespertilionis sp. nov.: A new cold-tolerant species of yeast isolated from bats
Malassezia is a genus of medically-important, lipid-dependent yeasts that live on the skin of warm-blooded animals. The 17 described species have been documented primarily on humans and domestic animals, but few studies have examined Malassezia species associated with more diverse host groups such as wildlife. While investigating the skin mycobiota of healthy bats, we isolated a...

Strengthening links between waterfowl research and management Strengthening links between waterfowl research and management
Waterfowl monitoring, research, regulation, and adaptive planning are leading the way in supporting science-informed wildlife management. However, increasing societal demands on natural resources have created a greater need for adaptable and successful linkages between waterfowl science and management. We presented a special session at the 2016 North American Duck Symposium, Annapolis...

Perissodactyla diet Perissodactyla diet
Perissodactyla (Schoch 1989) includes tapirs, rhinoceros, wild asses, horses, and zebras. It is the order of hoofed mammals referred to as “odd-toed ungulates” because its members have one to three weight-bearing toes and walk on hoofs or “ungules.” They are herbivores that are specialized to exploit grasslands and brushy habitat (rhinos, horses, asses, zebras) or dense tropical forests...

Contaminant-associated health effects in fishes from the Ottawa and Ashtabula Rivers, Ohio Contaminant-associated health effects in fishes from the Ottawa and Ashtabula Rivers, Ohio
The health of resident fishes serves as a biologically relevant barometer of aquatic ecosystem integrity. Here, the health of the Ottawa River and Ashtabula River (both within the Lake Erie Basin) were assessed using morphological and immunological biomarkers in brown bullheads (Ameiurus nebulosus) and largemouth bass (Micropterus salmoides). Biomarker metrics were compared to fish...
