Microhabitat Use Affects Brain Size And Structure In Intertidal Gobies, Gemma E. White, Culum Brown May 2016

Microhabitat Use Affects Brain Size And Structure In Intertidal Gobies, Gemma E. White, Culum Brown

Culum Brown, PhD

The ecological cognition hypothesis poses that the brains and behaviours of individuals are largely shaped by the environments in which they live and the associated challenges they must overcome during their lives. Here we examine the effect of environmental complexity on relative brain size in 4 species of intertidal gobies from differing habitats. Two species were rock pool specialists that lived on spatially complex rocky shores, while the remainder lived on dynamic, but structurally simple, sandy shores. We found that rock pool-dwelling species had relatively larger brains and telencephalons in particular, while sand-dwelling species had a larger optic tectum and ...

Cue Choice And Spatial Learning Ability Are Affected By Habitat Complexity In Intertidal Gobies, Gemma E. White, Culum Brown May 2016

Cue Choice And Spatial Learning Ability Are Affected By Habitat Complexity In Intertidal Gobies, Gemma E. White, Culum Brown

Culum Brown, PhD

Variation in the structural complexity of a habitat is known to have significant affects on the evolution of different populations and can shape behavior, morphology, and life-history traits. Here, we investigated whether habitat complexity influences a species’ capacity for spatial learning and cue choice by comparing the performance of 4 goby species from 2 contrasting habitats in a spatial task. Gobies were collected from dynamic, homogenous sandy shores and stable, spatially complex rock pool habitats. We trained fish to use a T-maze to find a hidden reward and asked whether they used local visual landmarks or body-centered methods for orientation ...

BACKGROUND AND OBJECTIVES: Current tools struggle to detect drug-resistant malaria parasites when infections contain multiple parasite clones, which is the norm in high transmission settings in Africa. Our aim was to develop and apply an approach for detecting resistance that overcomes the challenges of polyclonal infections without requiring a genetic marker for resistance.

METHODOLOGY: Clinical samples from patients treated with artemisinin combination therapy were collected from Tanzania and Cambodia. By deeply sequencing a hypervariable locus, we quantified the relative abundance of parasite subpopulations (defined by haplotypes of that locus) within infections and revealed evolutionary dynamics during treatment. Slow clearance is ...

Overwintering And Early Season Amplification Of Eastern Equine Encephalitis Virus In The Southeastern United States, Andrea Bingham Mar 2014

Overwintering And Early Season Amplification Of Eastern Equine Encephalitis Virus In The Southeastern United States, Andrea Bingham

Graduate Theses and Dissertations

Eastern equine encephalitis virus (EEEV) is a highly pathogenic arbovirus that causes severe disease, with a mortality rate of approximately 30-35% in humans and 80-90% in horses. Studies dating back to the 1930's have identified many of the epidemiological and ecological aspects of the virus. However, there are several aspects of EEEV's transmission cycle that remain unclear. In the northeastern states, transmission is seasonal, peaking in the late summer months, while in Florida there is year-round transmission of EEEV. Recent phylogenetic studies have also suggested that Florida may serve as a reservoir for EEEV; the virus may periodically ...

Parasites are agents of disease in humans, livestock, crops, and wildlife and are powerful representations of the ecological and historical context of the diseases they cause. Recognizing a nexus of professional opportunities and global public need, we gathered at the Cedar Point Biological Station of the University of Nebraska in September 2012 to formulate a cooperative and broad platform for providing essential information about the evolution, ecology, and epidemiology of parasites across host groups, parasite groups, geographical regions, and ecosystem types. A general protocol, documentation–assessment–monitoring–action (DAMA), suggests an integrated proposal to build a proactive capacity to understand ...


About Turkeys, The Humane Society Of The United States Jan 2010

About Turkeys, The Humane Society Of The United States

Agribusiness Collection

John James Audubon, a well-known bird expert and nature enthusiast, described wild turkeys as birds of great beauty. The history and origin of wild turkeys is uncertain, yet many share Audubon’s sentiment that the wild turkey is “one of the most interesting of the birds indigenous to the United States of America.” Today, wild turkeys can be found throughout the nation. Following the selection of the bald eagle as the American symbol, Benjamin Franklin remarked that the turkey was more “respectable”, and a “true original native”.

About Chickens, The Humane Society Of The United States

Agribusiness Collection

The chicken is the world’s most numerous domesticated bird, with over 52 billion farmed worldwide in 2008, rivaling the dog as the most ubiquitous domestic animal globally. These birds have fascinated scholars and researchers since the dawn of Western civilization, and recent studies are beginning to reveal the depths of their complexity and cognitive ability. According to Andrew F. Fraser, professor of veterinary surgery at Memorial University of Newfoundland, and Donald M. Broom, professor of animal welfare at University of Cambridge: “Those who have studied the behaviour of the domestic fowl in detail…, especially those who have looked at ...


Faecal-Centric Approaches To Wildlife Ecology And Conservation; Methods, Data And Ethics, C. T. Darimont, T. E. Reimchen, H. M. Bryan, P. C. Paquet Dec 2008

Faecal-Centric Approaches To Wildlife Ecology And Conservation; Methods, Data And Ethics, C. T. Darimont, T. E. Reimchen, H. M. Bryan, P. C. Paquet

Ethics and Conservation Biology Collection

Abundant and commonly encountered in the field, wildlife faeces have long attracted scientists. Recent advances in molecular techniques, however, especially when coupled with creative study designs, can now yield a great variety of high quality data. Herein, we review the opportunities and challenges of faecal-centric approaches to address ecological and conservation questions using wolves of coastal British Columbia, Canada, as a case system. We begin by discussing methodological considerations, which should have broad applicability to any wildlife study system. We then summarize the extensive and unique variety of data that has emerged from our ‘facts from faeces’ approach with wolves ...


Regulation Of Prolactin Secretion In A Nonphotoperiodic Breeder, The Zebra Finch, Debora Ellen Christensen Jan 2007

Regulation Of Prolactin Secretion In A Nonphotoperiodic Breeder, The Zebra Finch, Debora Ellen Christensen

Retrospective Theses and Dissertations

In avian species, high levels of prolactin (PRL) released from the anterior pituitary are associated with reproductive behaviors such as incubation and rearing of young. We studied reproduction-associated PRL levels in breeding and nonbreeding zebra finches. The general hypothesis of this dissertation was: The general pattern of PRL release in zebra finches is similar to other avian species, but differences in regulation of release can be expected due to the unique breeding environment in which these animals live.;The research was divided into four parts: (1) Determining the pattern of PRL release and secretion in response to vasoactive intestinal peptide ...


Behaviorally-Induced Periodic Cooling Of Avian Embryos , Christopher Robin Olson Jan 2006

Behaviorally-Induced Periodic Cooling Of Avian Embryos , Christopher Robin Olson

Retrospective Theses and Dissertations

For many bird embryos, periodic cooling occurs when the incubating adult leaves the nest to forage, but the effects of periodic cooling on embryo growth, yolk use and metabolism are poorly known. To address this question I conducted incubation experiments on eggs of zebra finches (Taeniopygia guttata ) that were frequently cooled and then rewarmed or were allowed to develop at a constant temperature. After 12 days of incubation, embryo mass and yolk reserves were less in eggs that experienced periodic cooling, compared to controls incubated constantly at 37.5°C. Embryos that regularly cooled to 20°C had higher mass-specific ...
