Bird Monitoring At Effigy Mounds National Monument, Iowa, Status Report 2009–2017, David G. Peitz, Lloyd W. Morrison, Kristen L. Mecke

United States National Park Service: Publications

Executive Summary

In 2009, the Heartland Inventory and Monitoring (I&M) Network) initiated breeding bird surveys on Effigy Mounds National Monument (NM), Iowa, to address two objectives: (1) to monitor changes in bird community composition and abundance, and (2) to improve our understanding of relationships between breeding birds and habitat and the effects of management actions on such relationships. This report evaluates trends in the park’s breeding bird populations in the context of trends observed within the North American Bird Conservation Initiative’s (NABCI) Prairie Hardwood Transition Bird Conservation Region, the bird conservation region in which the park is located. By doing …

Perceptual Lateralization Of Vocal Stimuli In Goats, Luigi Baciadonna, Christian Nawroth, Elodie F. Briefer, Alan G. Mcelligott

Communication Skills Collection

Functional asymmetries, for example, the preferential involvement of 1 brain hemisphere to process stimuli, may increase brain efficiency and the capacity to carry out tasks simultaneously. We investigated which hemisphere was primarily involved in processing acoustic stimuli in goats using a head-orienting paradigm. Three playbacks using goat vocalizations recorded in different contexts: food anticipation (positive), isolation (negative), food frustration (negative), as well as 1 playback involving dog barks (negative) were presented on the left and right sides of the test subjects simultaneously. The head-orienting response (left or right) and latency to resume feeding were recorded. The direction of the head-orienting …

Winter Field Report, December 2018 To February 2019, W. Ross Silcock

Nebraska Bird Review

As has been the trend in recent winters, and despite the relative coolness of this winter, there were numerous examples of species north of expected midwinter ranges or present in higher numbers than usual in winter. The long list includes unexpected midwinter records of Tundra Swan, American Wigeon, Ring-necked Duck, Lesser Scaup, White-winged Dove, Sandhill Crane, Clark’s Grebe, Doublecrested Cormorant, Red-shouldered Hawk, and Yellow-bellied Sapsucker. Startling was the state’s first winter record of Sedge Wren, perhaps the biggest rarity of the season. And Eastern Meadowlark was documented in midwinter for the first time, although its presence in the southeast has …

Behavioral Flexibility Of A Generalist Carnivore, Sarah E. Daniels, Rachel E. Fanelli, Amy Gilbert, Sarah Sarah Benson‑Amram

USDA Wildlife Services: Staff Publications

Innovative problem solving, repeated innovation, learning, and inhibitory control are cognitive abilities commonly regarded as important components of behaviorally flexible species. Animals exhibiting these cognitive abilities may be more likely to adapt to the unique demands of living in novel and rapidly changing environments, such as urbanized landscapes. Raccoons

(Procyon lotor) are an abundant, generalist species frequently found in urban habitats, and are capable of innovative problem solving, which makes them an ideal species to assess their behavioral flexibility. We gave 20 captive raccoons a multi-access puzzle box to investigate which behavioral and cognitive mechanisms enable the generation …

Examining Derelict Pot Impacts On Harvest In A Commercial Blue Crab Callinectes Sapidus Fishery, James A. Delbene, Donna M. Bilkovic, Andrew M. Scheld

VIMS Articles

Pot fisheries occur worldwide with a significant proportion of the gear becoming derelict. Derelict pots induce detrimental ecological and economic impacts, and more recently were found to reduce blue crab harvests in the Chesapeake Bay commercial fishery. We simulated the presence of derelict pots near actively fished pots in seasonal field experiments to quantify the effect derelict pots have on blue crab harvest. Derelict pots reduced harvests by 30% during the summer, but not during the fall. Female blue crab capture rates were consistently lower when derelict pots were present; while capture rates of the less abundant males were not …

Development Of An Industry-Based Habitat Mapping/Monitoring System Frdc Project No 2011/021, Simon De Lestang, Matthew B. Pember, Dirk Slawinski

Fisheries research reports

Mapping / monitoring in the marine environment can be a very costly exercise. Scientists from the Department of Primary Industries and Regional Development; Fisheries Division (FD) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) have developed a small, low-cost automated camera system that, when fitted to commercial fishing gear, can achieve this at minimal cost. The POTBot (Pictures Of The Bottom) system is a cheap, small “smart” camera that can track its position globally and the date and time, and can record high-definition video and water temperature readings when it determines it has been deployed into the ocean.

The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer

Dissertations, Theses, and Capstone Projects

Primate evolutionary history is inexorably linked to the evolution of a broad array of locomotor adaptations that have facilitated the clade’s invasion of new niches. Researchers studying the evolution of primates and of their individual locomotor adaptations have traditionally relied on bony morphology – a practical choice given the virtual non-existence of any other type of tissue in the fossil record. However, this focus downplays the potential importance of the many other structures involved in locomotion, such as muscle, cartilage, and neural tissue, which may each be influenced by separate selective forces because of their different roles in facilitating movement. …

Optimizing Gastrointestinal Integrity In Poultry: The Role Of Nutrients And Feed Additives, Sunday A. Adedokun, Opeyemi C. Olojede

Animal and Food Sciences Faculty Publications

Immunomodulation of the immune system by stimulating or suppressing one or both arms, is an emerging concept driven by the understanding of the host defense system. In particular, the gastrointestinal tract (GIT) functions not only as a site for digestion and absorption of nutrients but also acts as a metabolic and immunological organ. This serves as a barrier against abnormal presentation of luminal constituents, caused by dysfunctional intestinal epithelial barrier, to the mucosal immune system. Invasion by pathogens in the case of disease or stress or a massive influx of commensal bacteria overcomes the defensive mechanisms, resulting in the full …

Habitat Usage Patterns Of Bottlenose Dolphins (Tursiops Truncatus) In Terrebonne And Timbalier Bays, Louisiana, Mary Allison Manning

LSU Master's Theses

I coupled fine-scale environmental data with observed behavior and group composition data to examine overall distribution within the bay system and to characterize the habitat associated with foraging and the presence of calves. Semi-isolated populations of bottlenose dolphins (Tursiops truncatus) along Louisiana’s coast are undergoing increased risks from boat traffic, oil spills, land subsidence, and planned water diversions (CPRA 2017). Characterizing the habitat use of bottlenose dolphins in Terrebonne and Timbalier bays, Louisiana, is important given the likely high site fidelity, small home ranges, and low exchange of individuals with nearby coastal populations (Lane et al. 2015, McDonald …

A Global Reassessment Of Solitary-Sociable Dolphins, Laetitia Nunny, Mark P. Simmonds

Mark P. Simmonds, OBE

Dolphins are typically regarded as highly social animals. However, some individuals live apart from their own species and may come to socialize with people through a recognized series of stages which are presented and expanded on in this paper. The term “solitary-sociable dolphins” has been used to describe these animals and such individuals have been identified from several different species and reported in many parts of the world. In many instances, the interactions with people that may follow their original isolation, and which typically become more intense over time, have created situations where the welfare of the animal has been …

Challenges In Columbia River Fisheries Conservation: A Response To Duda Et Al., Brian K. Hand, Courtney G. Flint, Chris A. Frissell, Clint C. Muhlfeld, Shawn P. Devlin, Brian P. Kennedy, Robert L. Crabtree, W. Arthur Mckee, Gordon Luikart, Jack A. Stanford

Sociology, Social Work and Anthropology Faculty Publications

The salmonid fisheries of the Columbia River Basin (CRB) have enormous socioeconomic, cultural, and ecological importance to numerous diverse stakeholders (eg state, federal, tribal, nonprofit), and there are a wide array of opinions and perspectives on how these fisheries should be managed. Although we appreciate Duda et al.'s commentary, it offers only one perspective of many in this context. The objective of our paper (Hand et al. 2018) was to provide justification for “the importance of social–ecological perspectives when communicating conservation values and goals, and the role of independent science in guiding management policy and practice for …

Does The Seal Licensing System In Scotland Have A Negative Impact On Seal Welfare?, Laetitia Nunny, Fritha Langford, Mark P. Simmonds

Mark P. Simmonds, OBE

This study examined the licensing system that permits seal shooting in Scotland, which was established under Part 6 Conservation of Seals of the Marine (Scotland) Act 2010. Four approaches were used: data were collated and analyzed from both the Scottish Government and Scottish Marine Animal Stranding Scheme; a survey was sent to current license holders and informal interviews were conducted with key stakeholder types. Between February 2011 and the end of October 2015, 1229 gray seals, and 275 common seals were reported shot under license to the Scottish Government. The numbers of seals reported as shot has reduced year-on-year since …

People -- Marine Mammal Interactions, Andrew Butterworth, Mark P. Simmonds

Mark P. Simmonds, OBE

Our relationships with marine mammals are complex. We have used them as resources, and in some places this remains the case; viewed them as competitors and culled them (again ongoing in some localities); been so captivated and intrigued by them that we have taken them into captivity for our entertainment; and developed a lucrative eco-tourism activity focused on them in many nations. When we first envisaged this special topic, we had two overarching aims:

Firstly, we hoped to generate critical evaluation of some of our relationships with these animals.

Secondly, we hoped to attract knowledgeable commentators and experts who might …

Animal, Dairy, and Veterinary Science Faculty Publications

To address the unmet needs for human polyclonal antibodies both as therapeutics and diagnostic reagents, building upon our previously established transchromosomic (Tc) cattle platform, we report herein the development of a Tc goat system expressing human polyclonal antibodies in their sera. In the Tc goat system, a human artificial chromosome (HAC) comprising the entire human immunoglobulin (Ig) gene repertoire in the germline configuration was introduced into the genetic makeup of the domestic goat. We achieved this by transferring the HAC into goat fetal fibroblast cells followed by somatic cell nuclear transfer for Tc goat production. Gene and protein expression analyses …
