Long-distance migrants are under strong selection to arrive on their breeding grounds at a time that maximizes fitness. Many arctic birds start nesting shortly after snow recedes from their breeding sites and timing of snowmelt can vary substantially over the breeding range of widespread species. We tested the hypothesis that migration schedules of individuals co-occurring at the same non-breeding areas are adapted to average local environmental conditions encountered at their specific and distant Arctic breeding locations. We predicted that timing of breeding site availability (measured here as the average snow-free date) should explain individual variation in departure time from shared ...


Attitudes And Interactions Of Indigenous And Non-Indigenous People With Wildlife In The Northern Talamanca Mountains Of Costa Rica, Carolina Saenz-Bolaños 2021 University of Massachusetts Amherst

Attitudes And Interactions Of Indigenous And Non-Indigenous People With Wildlife In The Northern Talamanca Mountains Of Costa Rica, Carolina Saenz-Bolaños

Doctoral Dissertations

In this study I investigated wildlife and human use of landscapes in the northern Talamanca Mountains of Costa Rica (Pacuare-Barbilla sector), including three contiguous protected areas (a national park, a forest reserve, and an indigenous territory), as well as surrounding unprotected areas. I describe and compare perceptions of wildlife by different social actors in the Pacuare-Barbilla sector, collecting information with a questionnaire as an instrument. I also inventoried and monitored the abundance and distribution of a variety of wildlife species occurring throughout the area using camera traps. The species with greater abundance or only occurrence in the national park were ...


Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan 2021 University of Massachusetts Amherst

Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan

Doctoral Dissertations

Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal ...

Journal of Bioresource Management

Mosquitoes are the most terrifying both for their abundance and for the diseases they transmit. They are vectors of malaria, lymphatic filariasis and arbovirus such as yellow fever, dengue, viral encephalitis and African horse sickness. These characteristics give this fauna prominent importance and health interest. To identify the most widespread mosquito species, we conducted for the first time an inventory in the Aures region more particularly the wilaya of Batna (East of Algeria) from May 2017 to January 2020, we studied their diversity, abundance and distribution. The sampling is done by monthly surveys of the various localities chosen, using the ...

Free-Ranging And Feral Cats, Alex Dutcher, Kyle Pias, Grant Sizemore, Stephen M. Vantassel

Wildlife Damage Management Technical Series

Domestic cats (Felis catus) are a common household pet in the United States, with an estimated 25.4% of households owning cats (American Veterinary Medical Association 2018). While an increasing number of cat owners keep their pet cats exclusively indoors, a portion of society maintains that domestic cats are entitled to a free-ranging lifestyle and may even consider unowned domestic cats to be wildlife. Although wildlife managers recognize the beliefs of many concerned stakeholders, including advocates who use strong emotional appeals on behalf of cats, it remains that free-ranging and feral domestic cats are an invasive species spread by humans ...


Remote Detection Of Disturbance From Motorized Vehicle Use In Appalachian Wetlands, Walter Smith 2021 The University of Virginia's College at Wise

Remote Detection Of Disturbance From Motorized Vehicle Use In Appalachian Wetlands, Walter Smith

Virginia Journal of Science

Wetland disturbance from motorized vehicle use is a growing concern across the Appalachian coalfields of southwestern Virginia and portions of adjacent states, particularly as both extractive industries and outdoor recreation development expand in regional communities. However, few attempts have been made in this region or elsewhere to adapt approaches that can assist researchers and land managers in remotely identifying and monitoring wetland habitats disturbed by motorized vehicle use. A comparative analysis of wetlands impacted and unimpacted by off-road vehicle activity at a public recreation area in Tazewell County, Virginia was conducted to determine if and how a common, satellite-derived index ...

Blanding’S Turtle (Emydoidea Blandingii): Species Conservation Assessment, Melissa J. Panella, Colleen Rothe-Groleau

Nebraska Game and Parks Commission Publications

The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Blanding’s turtle (Emydoidea blandingii) as a Tier I at-risk species. Some general management recommendations are made here regarding Blanding’s turtles; however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of this at-risk turtle that will aid in ...


A Socio-Ecological Perspective On Integrating Biodiversity Conservation And The Security-Development Nexus In Sub-Saharan Africa, Lilyon Conroy 2021 SIT Study Abroad

A Socio-Ecological Perspective On Integrating Biodiversity Conservation And The Security-Development Nexus In Sub-Saharan Africa, Lilyon Conroy

Independent Study Project (ISP) Collection

The purpose of this paper is to examine the potential of community-based biodiversity conservation as a security-development strategy in Sub-Saharan Africa. While the creation of the security-development nexus has been an essential component in mainstreaming the principles of sustainable human development, there exist numerous gaps in the nexus. With the aid of four expert interviews, this analysis critically assesses the role of the environment and of local communities in successfully implementing the security-development nexus. Using the existing body of work comprising the security-development nexus as a framework, this research examines why biodiversity conservation has been overlooked as a security-development strategy ...

Man V.S. Wild: An Analysis Of Language Used Regarding Human-Wildlife Conflict In The Kibale National Park Community, Western Region, Uganda, Sophie Perfetto

Independent Study Project (ISP) Collection

If humans are to live sustainably and in harmony with wildlife in the vicinity of Protected Areas, policy makers, and government authorities need to make informed decisions with consideration to the needs of local communities. For this to happen, policy makers must understand the perceptions of local communities and take local perspectives into account. As language is at the root of perception, language was studied in the context of its role in shaping local perceptions of human-wildlife conflict and consequential conflict mitigation strategies. Six communities around the Northern region of Kibale National Park, Uganda, were studied, with sites located in ...

Snow Buntings Maintain Winter-Level Cold Endurance While Migrating To The High Arctic, Audrey Le Pogam, Ryan S. O’Connor, Oliver P. Love, Justine Drolet, Lyette Régimbald, Gabrielle Roy, Marie Pier Laplante, Dominique Berteaux, Andrew Tam, François Vézina 2021 Université du Québec à Rimouski

Snow Buntings Maintain Winter-Level Cold Endurance While Migrating To The High Arctic, Audrey Le Pogam, Ryan S. O’Connor, Oliver P. Love, Justine Drolet, Lyette Régimbald, Gabrielle Roy, Marie Pier Laplante, Dominique Berteaux, Andrew Tam, François Vézina

Great Lakes Institute for Environmental Research Publications

Arctic breeding songbirds migrate early in the spring and can face winter environments requiring cold endurance throughout their journey. One such species, the snow bunting (Plectrophenax nivalis), is known for its significant thermogenic capacity. Empirical studies suggest that buntings can indeed maintain winter cold acclimatization into the migratory and breeding phenotypes when kept captive on their wintering grounds. This capacity could be advantageous not only for migrating in a cold environment, but also for facing unpredictable Arctic weather on arrival and during preparation for breeding. However, migration also typically leads to declines in the sizes of several body components linked ...

Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elain Lek, Joshua Brown

Fisheries research reports

Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people ...


Eradicating Zebra Mussels: What Works?, Elijah Davies 2021 Kennesaw State University

Eradicating Zebra Mussels: What Works?, Elijah Davies

Symposium of Student Scholars

The invasion of U.S lakes and rivers by the invasive species of zebra mussels called Dreissena polymorpha has caused catastrophic harm to the local ecosystem by reproducing and outcompeting native mussel species as well as harm to pipes leading into water sources by binding to surfaces and reproducing to the point that the mussels clog pipes. In addition, recreation areas must be closed due to the sharp shells making areas unusable. In the past, research has focused on individual molluscicides and their eradication of zebra mussels, as well as their effect on native flora and fauna. My research will ...
