Demographic Consequences Of Off-River Nesting For Piping Plover (Charadrius Melodus) And Interior Least Tern (Sternula Antillarum Athalassos) In The Lower Platte River System, Nebraska, Elsa M. Forsberg
School of Natural Resources: Dissertations, Theses, and Student Research
Piping plovers (Charadrius melodus; hereafter, plovers) and interior least terns (Sternula antillarum athalassos; hereafter, terns) are two avian species that nest along the Lower Platte River system (LPRS) in Nebraska. In the LPRS, river sandbars provide natural nesting habitat, but off-river sites provide substantial nesting habitat especially when sandbar habitat is scarce. Although presumed to be important for the persistence of plovers and terns, off-river habitat is not self-sustaining and predicted to decline. Understanding the vital rates of plovers and terns in the LPRS will inform the role of off- river sites in the future conservation …
Rabies Virus Serosurvey Of The Small Indian Mongoose (Urva Auropunctata) Across Multiple Habitats In Puerto Rico, 2014–21, Are R. Berentsen, Mel J. Rivera-Rodriguez, Fabiola B. Torres-Toledo, Amy J. Davis, Richard Chipman, Amy Gilbert
Rabies Virus Serosurvey Of The Small Indian Mongoose (Urva Auropunctata) Across Multiple Habitats In Puerto Rico, 2014–21, Are R. Berentsen, Mel J. Rivera-Rodriguez, Fabiola B. Torres-Toledo, Amy J. Davis, Richard Chipman, Amy Gilbert
USDA Wildlife Services: Staff Publications
The small Indian mongoose (Urva auropuncata) is a rabies reservoir in Puerto Rico and accounts for over 70% of reported animal rabies cases annually. The presence of rabies virus-neutralizing antibodies (RVNA) is often used as a tool to measure exposure to rabies virus in wildlife populations. We conducted a serosurvey of mongooses at 11 sites representing six habitat types across Puerto Rico. We collected a serum sample from 464 individual mongooses during 2014–2021. Overall, 80/464 (17.0%; 95% confidence interval, 14.1–20.9%; 55 male, 23 female, and two sexes not recorded) of individual mongooses sampled across all habitats were RVNA …
Vigilance Of Nesting Whooping Cranes In Juneau County, Wisconsin, Nicole M. Gordon, Darby P. Bolt, Hillary L. Thompson
Vigilance Of Nesting Whooping Cranes In Juneau County, Wisconsin, Nicole M. Gordon, Darby P. Bolt, Hillary L. Thompson
Proceedings of the North American Crane Workshop
Vigilance plays an important role in the detection of possible threats and reducing the risk of predation, including during the incubation period. We examined the visual vigilance of incubating whooping cranes (Grus americana) in Juneau County, Wisconsin, during the 2019 nesting season. We deployed 9 trail cameras and tagged crane presence and behavior in 32,801 photos which were used in our analysis. We assessed individual nest and environmental variables and their effects on vigilant behavior of incubating cranes using linear mixed-models. Vigilant behavior was defined by a posture in which the crane’s head was up, neck was erect, …
Whooping Crane Stay Length In Relation To Stopover Site Characteristics, Andrew J. Caven, Aaron T. Pearse, David A. Brandt, Mary J. Harner, Greg D. Wright, David M. Baasch, Emma M. Brinley Buckley, Kristine L. Metzger, Matthew R. Rabbe,, Anne E. Lacy
Whooping Crane Stay Length In Relation To Stopover Site Characteristics, Andrew J. Caven, Aaron T. Pearse, David A. Brandt, Mary J. Harner, Greg D. Wright, David M. Baasch, Emma M. Brinley Buckley, Kristine L. Metzger, Matthew R. Rabbe,, Anne E. Lacy
Proceedings of the North American Crane Workshop
Whooping crane (Grus americana) migratory stopovers can vary in length from hours to more than a month. Stopover sites provide food resources and safety essential for the completion of migration. Factors such as weather, climate, demographics of migrating groups, and physiological condition of migrants influence migratory movements of cranes (Gruidae) to varying degrees. However, little research has examined the relationship between habitat characteristics and stopover stay length in cranes. Site quality may relate to stay length with longer stays that allow individuals to improve body condition, or with shorter stays because of increased foraging efficiency. We examined this …

Institute Publications
European green crab pose documented threats to cultured and wild shellfish, eelgrass, and shoreline habitats and ecosystems. Because they can prey on juvenile crabs and shellfish, dense populations of EGC in the Salish Sea region could put fisheries and aquaculture resources in peril. After Fisheries and Oceans Canada researchers reported an established EGC population in Sooke Basin, BC in 2012, the Washington Department of Fish and Wildlife (WDFW) worked with Washington Sea Grant (WSG) to secure Puget Sound Marine and Nearshore Grant Program funding and establish a volunteer-based early detection and monitoring program. WSG launched Crab Team in 2015 with …
Collective Effect Of Landfills And Landscape Composition On Bird–Aircraft Collisions, Morgan Pfeiffer, Bradley F. Blackwell, Travis L. Devault
Collective Effect Of Landfills And Landscape Composition On Bird–Aircraft Collisions, Morgan Pfeiffer, Bradley F. Blackwell, Travis L. Devault
USDA Wildlife Services: Staff Publications
Ninety-three percent of all reported bird strikes occur below 1,067 m, which based on the typical approach and departure angles of aircraft is within 8–13 km of an airport. Concomitantly, the Federal Aviation Administration and the International Civil Aviation Organization recommend that any feature that would attract hazardous wildlife to the approach and departure airspace be restricted. Thus, preventing the establishment of wildlife attractants, such as municipal solid waste landfills (MSWLFs) within 8 km or 13 km extents (U.S. and international recommendations, respectively) of airports, has been recommended to mitigate the risk of bird–aircraft collisions (strikes). However, robust evidence linking …
Range Extension For Dekay’S Brownsnake (Storeria Dekayi) In South-Central Nebraska, Macy K. Cool, Keith Geluso
Range Extension For Dekay’S Brownsnake (Storeria Dekayi) In South-Central Nebraska, Macy K. Cool, Keith Geluso
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Dekay’s Brownsnake (Storeria dekayi) generally occurs in southeastern parts of the state, where the species was known from 16 counties. Herein, we update the distribution of S. dekayi in the state and briefly comment on habitat and abundance from observations in September and October 2018. We documented 7 new county records that extend its distribution in south-central Nebraska. We observed that S. dekayi does not only reside in mesic wooded habitats in Nebraska but also occupies open environments, including areas with upland grasslands and row-crop agriculture. Dekay’s Brownsnake currently is listed as a species of concern …

Presence And Distribution Of Leptodactylus Guianensis Heyer And De Sa, 2011 In Colombia: Comparisons With Other Species In The L. Latrans Group., Mariela Osorno Muñoz, Doris L. Gutiérrez-Lamus, Rafael O. De Sá
Biology Faculty Publications
Leptodactylus guianensis is reported for the first time for Colombia along with a distributional map of the species. The species is the fifth species of the L. latransspecies group documented in the country. Males possess a single, conical and slightly chisel-shaped thumb spine; only three species in the group have a single thumb spine. In collections, specimens of L. guianensis are misidentified as L. macrosternum, L. latrans or L. bolivianus. We provide morphological, colouration and habitat descriptions for where the species occurs in Colombia.
Japanese Beetles’ Feeding On Milkweed Flowers May Compromise Efforts To Restore Monarch Butterfly Habitat, Adam M. Baker, Daniel A. Potter
Japanese Beetles’ Feeding On Milkweed Flowers May Compromise Efforts To Restore Monarch Butterfly Habitat, Adam M. Baker, Daniel A. Potter
Entomology Faculty Publications
The eastern North American migratory population of monarch butterflies (Danaus plexippus) is in serious decline. Habitat restoration, including adding millions of host plants to compensate for loss of milkweed in US cropland, is a key part of the international conservation strategy to return this iconic butterfly to sustainable status. We report here that Popillia japonica, a polyphagous, invasive beetle, aggregates and feeds on flowers of Asclepias syriaca, the monarch’s most important larval food plant, reducing fruiting and seed set by >90% and extensively damaging milkweed umbels in the field. The beetle’s ongoing incursion into the monarch’s …
Habitat Selection And Con- And Heterospecific Associations Of Wintering Whooping Cranes At Wheeler National Wildlife Refuge, Alabama, Andrew W. Cantrell, Yong Wang
Habitat Selection And Con- And Heterospecific Associations Of Wintering Whooping Cranes At Wheeler National Wildlife Refuge, Alabama, Andrew W. Cantrell, Yong Wang
Proceedings of the North American Crane Workshop
Winter ecology of the Eastern Migratory Population of whooping cranes (Grus americana) has received less detailed study than that of other life stages or the Aransas-Wood Buffalo Population. Increased winter use of novel sites by these cranes makes understanding the mechanisms contributing to habitat selection and use important for efficient conservation. As a subset of a larger and ongoing project, this study examined the individual and temporal variations of occupancy times, habitat types used, and co-occurrence with con- and heterospecifics during winters 2014-15 and 2015-16 at Wheeler National Wildlife Refuge, Alabama, while considering the effect of individual life …
Effectiveness Of Chain Link Turtle Fence And Culverts In Reducing Turtle Mortality And Providing Connectivity Along U.S. Hwy 83, Valentine National Wildlife Refuge, Nebraska, Usa, Marcel P. Huijser, Kari E. Gunson, Elizabeth R. Fairbank
Effectiveness Of Chain Link Turtle Fence And Culverts In Reducing Turtle Mortality And Providing Connectivity Along U.S. Hwy 83, Valentine National Wildlife Refuge, Nebraska, Usa, Marcel P. Huijser, Kari E. Gunson, Elizabeth R. Fairbank
Nebraska Department of Transportation: Research Reports
We evaluated the effectiveness of existing turtle fences through collecting and analyzing turtle mortality data along U.S. Hwy 83, in and around Valentine National Wildlife Refuge, Nebraska, USA. We also investigated the level of connectivity for turtles provided through the culverts that were originally designed to pass water through a capture-mark-recapture experiment. While fenced valley sections had 33.1% fewer turtle observations than unfenced valley sections, the difference was not significant. However, we think that the effectiveness of the fence can be improved through fence repairs, other modifications of the fences, vegetation maintenance, and extending the length of the fences. Four …
Winter And Migratory Habitat Use Of Six Eastern Greater Sandhill Cranes, Hillary L. Thompson, Anne E. Lacy
Winter And Migratory Habitat Use Of Six Eastern Greater Sandhill Cranes, Hillary L. Thompson, Anne E. Lacy
Proceedings of the North American Crane Workshop
To better understand non-breeding ecology of sandhill cranes (Grus canadensis tabida), we harnessed 6 satellite GPS transmitters to adult cranes from 1 central Wisconsin breeding area. Using location data from these transmitters, we investigated non-breeding movements, including the routes and timing of migration. By combining satellite GPS data with a national land cover dataset, we also described habitat use on stopovers and wintering areas. Sandhill cranes tended to use larger home ranges on long stopovers (>3 days) than on short stopovers (3 days or less). The durations of northward migrations were longer and had more stopovers than …
Cercyonis Pegala Agawamensis (Satyridae): A New Butterfly Subspecies From The Coastal Salt Marshes Of The Northeastern United States Of America, Matthew D. Arey, Alex Grkovich
Cercyonis Pegala Agawamensis (Satyridae): A New Butterfly Subspecies From The Coastal Salt Marshes Of The Northeastern United States Of America, Matthew D. Arey, Alex Grkovich
The Taxonomic Report of the International Lepidoptera Survey
A new subspecies of the Common Wood Nymph (Cercyonis pegala) from the New England coastline in the northeastern region of the United States is described on the basis of phenotype, behavior, habitat, seasonality, flight period, and phenology. Agawamensis is univoltine as in all pegala. The newly described subspecies occurs almost entirely in coastal salt marshes and estuarine meadows, quite atypical as understood for Cercyonis pegala. The newly described subspecies agawamensis predominately prefers and occurs within large open salt marshes but can also be found in similar habitat along smaller tidal rivers, coastal inlets and streams

Ecology Collection
The main objectives of this study were (1) to estimate the population size of Risso’s dolphins off Bardsey Island using mark-recapture techniques (De Boer et al., 2013); and (2) to study habitat-use in relation to fine-scale oceanographic features. This work provides preliminary information on the habitat-use of Risso’s dolphins and will benefit future studies, along with the development of effective conservation measures for this species throughout the region.
Habitat-Mediated Foraging Limitations Drive Survival Bottlenecks For Juvenile Salmon, Brian P. Kennedy, Keith H. Nislow, Carol L. Folt
Habitat-Mediated Foraging Limitations Drive Survival Bottlenecks For Juvenile Salmon, Brian P. Kennedy, Keith H. Nislow, Carol L. Folt
Dartmouth Scholarship
Realistic population models and effective conservation strategies require a thorough understanding of mechanisms driving stage-specific mortality. Mortality bottlenecks for many species occur in the juvenile stage and are thought to result from limitation on food or foraging habitat during a "critical period" for growth and survival. Without a way to account for maternal effects or to measure integrated consumption rates in the field, it has been virtually impossible to test these relationships directly. Hence uncertainties about mechanisms underlying such bottlenecks remain. In this study we randomize maternal effects across sites and apply a new method for measuring consumption integrated over …
Use Of Wading Birds As Indicators Of Potential Whooping Crane Wintering Habitat, Dawn A. Sherry, Felipe Chavez-Ramirez
Use Of Wading Birds As Indicators Of Potential Whooping Crane Wintering Habitat, Dawn A. Sherry, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
A search for suitable wintering sites on which to establish another migratory population of whooping crane (Grus americana) has been conducted and will continue. In addition to an evaluation of food availability for whooping cranes, wading birds that overlap highly in patterns of habitat utilization with whooping cranes may be useful as indirect indicators of suitable whooping crane habitat. We determined the extent to which several species of wading birds overlap in patterns of habitat utilization with whooping cranes on their current wintering grounds. We conducted aerial surveys of whooping cranes and wading birds at Aransas and Matagorda …
Linking Dispersal To Local Population Dynamics: A Case Study Using A Headwater Salamander System, Winsor H. Lowe
Linking Dispersal To Local Population Dynamics: A Case Study Using A Headwater Salamander System, Winsor H. Lowe
Dartmouth Scholarship
Dispersal can strongly influence local population dynamics and may be critical to species persistence in fragmented landscapes. Theory predicts that dispersal by resident stream organisms is necessary to offset the loss of individuals to downstream drift. However, there is a lack of empirical data linking dispersal and drift to local population dynamics in streams, leading to uncertainty regarding the general demographic significance of these processes and the power of drift to explain observed dispersal patterns. I assessed the contribution of dispersal along a first-order stream to population dynamics of the headwater salamander Gyrinophilus porphyriticus (Plethodontidae). I conducted mark–recapture surveys of …

The Lancelin Island Lagoon is a small area of reef habitat on the western side of Lancelin Island and a popular snorkelling and diving destination. Water depth ranges from less than 0.3 m on the intertidal reefs to less than 3 m on the sand or seagrass-covered bottom. The area has a diverse array of benthic marine habitat. During a marine survey of the area, over 200 flora and fauna species were positively identified, with many more remaining unidentified due to the diversity of species supported in this marine environment. The survey, which was facilitated by direct observations and photographs, …
Survival And Habitat Use Of Greater Sandhill Crane Colts On Modoc National Wildlife Refuge, California, Kevin J. Desroberts
Survival And Habitat Use Of Greater Sandhill Crane Colts On Modoc National Wildlife Refuge, California, Kevin J. Desroberts
Proceedings of the North American Crane Workshop
Radiotelemetry was used to monitor 13 (1990) and 14 (1992) greater sandhill crane (Grus canadensis tabida) colts on Modoc National Wildlife Refuge, California, to determine causes of mortality, brood habitat utilization, and effects of habitat management on colt survival. Colt survival rates were 0.36 (1990) and 0.54 (1992). Coyotes (Canis latrans) killed 3 colts and mink (Mustela vison) killed 4; I colt died because of a bacterial infection (Staphylococcus aureous). Broods used 6 different habitat types and 79% used more than I type. Irrigated meadows (74%), cultivated uplands (53 %), and marsh …
Sandhill Crane Habitat Use In Northeastern Utah And Southwestern Wyoming, Donald E. Mcivor, Michael R. Conover
Sandhill Crane Habitat Use In Northeastern Utah And Southwestern Wyoming, Donald E. Mcivor, Michael R. Conover
Proceedings of the North American Crane Workshop
Patterns of habitat use by greater sandhill cranes (Grus canadensis tabida) were examined during April-July 1991 when crop damage attributed to cranes normally occurs. We conducted surveys weekJy along 37-km transects in Cache Valley, Utah, and bi-weekly in the Bear River Valley in Rich County, Utah, and Lincoln County. Wyoming. During the surveys, we sighted 1,235 cranes in 165 separate groups in pasture (55%), small grains (19%), riparian (8%), alfalfa (6%), corn (3%), and miscellaneous (9%) habitats. Cranes did not use habitats in proportion to their availability (P < 0.0005); they fed more in small grain fields and pasture-hay habitats. Depredations attributed to cranes have been reported in Cache Valley corn crops in spring and in Bear River Valley small grain crops in fall. Farmers with chronic depredation problems in small grains and corn may wish to cultivate crops less preferred by cranes.
Using National Wetlands Inventory Maps To Quantify Whooping Crane Stopover Habitat In Oklahoma, Dale W. Stahlecker
Using National Wetlands Inventory Maps To Quantify Whooping Crane Stopover Habitat In Oklahoma, Dale W. Stahlecker
Proceedings of the North American Crane Workshop
Three stratified random samples of the 416 National Wetland Inventory (NWI) maps within the western Oklahoma portion of the Wood Buffalo-Aransas whooping crane (Grus americana) migration corridor were used to evaluate the availability of wetland roost sites. Wetlands were eliminated as potential roosts if visibility was obscured by vegetation or slope, or if certain human activities occurred within 100-800 m. Thirty percent of all wetlands >0.04 ha passed map review, but only 7% passed when ground truthed. NWI map review was a poor predictor of suitability (33 % correct) but a good predictor of unsuitability (97 % correct). …
Urban Wildlife Habitat -- Present And Future, David Tylka
Urban Wildlife Habitat -- Present And Future, David Tylka
Ecology Collection
Many kinds of wild animals can become adapted to living in cities, provided that the right kinds of habitats are available and that their presence is accepted by city-dwellers. Suitable habitats can be furnished by traditional parks, tracts of "wild acres" set aside by cities, linear parks, cemeteries and golf courses, and transportation corridors. Buildings, rooftops, and institutional grounds can also provide habitat for animals like birds and butterfiles. Suburban areas can encourage the growth of local wildlife by neglecting to mow common grounds, or allowing sections of individual lawns to grow up with wild vegetation.
