Responses of the Ocellated Turkey (Meleagris ocellata) to Human Disturbance
… Chapter Two describes the association of habitat disturbance with male movement patterns and select indicators of health. There were no significant differences in home range size, blood and fecal parasites, feather barring regularity, male fleshy ornaments, and H:L ratios among the disturbance …

The effects of human disturbance on breeding and foraging birds
… the current literature describing the effects of disturbance on wildlife, concentrating mainly on birds (Chapter 1). Recent literature has provided worrying critiques of the practical and theoretical bases upon which management practice is based. Here, I address a number of questions that seek to …

Reducing Human Disturbance to Atlantic Flyway Shorebirds Using Social Science Methods
Human disturbance is a significant threat to shorebirds in North America. Disturbance can result in direct mortality or have long-term impacts on the survival of shorebirds. Land managers employ a variety of management techniques to minimize anthropogenic impacts on shorebirds, but because the …

The effects of human disturbance and climatic conditions on breeding Cassin’s auklets
Human disturbance has been observed to have effects on wildlife. These effects can be either positive or negative, depending on the study species; however, most of the research done to date has demonstrated negative effects that are reflective in the behaviour and reproductive biologyof the …

Benthic metrics as indicators of human disturbance in a marine-dominated lagoon
… to identify key bioindicators that can detect disturbance-induced ecosystem change. Benthic metrics are an excellent example of disturbance indicators in soft sediment based aquatic systems, and are directly applicable to one of South Africa’s most economically and ecologically significant …

Sediment redistribution in the Uilkraals estuary as a consequence of human disturbance
… the Uilkraals estuary, have been affected by human disturbance; focusing on the impacts arising from construction of two temporary embankments and a permanent bridge and embankment. The Uilkraals estuary is situated in the south-western Cape, approximately 60 kilometres north-west of Cape …

Effects of human disturbance on the behavior and energetics of nonbreeding sanderlings
Human disturbance of avifauna and other wildlife is defined as any intentional or unintentional anthropogenic action that elicits a metabolic or behavioral response. I proposed that the energetic response to disturbance should be reflected as increased existence metabolism (EM). If so, then there …

Impacts of Human Disturbance on the Behavior of Sanderlings on the Georgia Coast
… a serious impact on wildlife. However, even when humans do not destroy habitat, their activity can have negative impacts on behavior. The purpose of my study was (1) to test whether the presence of humans altered the behavior of Sanderlings (Calidris alba), (2) to quantify the impacts of staged …

Impact of human disturbance on coastal birds: population consequences derived from behavioural responses
Disturbance of wildlife is inevitable in a world with a rapidly increasing human population. Whilst improving engagement with the natural world can have the benefit of encouraging people to help protect it, there is also the issue of increased potential for damaging effects of disturbance. A better …

The Influence of Human Disturbance on Avian Frugivory and Seed Dispersal in a Neotropical Rainforest
Habitat loss and disturbance due to human activity are major causes of global biodiversity decline. Beyond outright species loss, one potential outcome is modification of species interactions that are integral to ecosystem functioning. To investigate this possibility, I asked whether human activity …

Assessing the impacts of human disturbance on wildlife: insights from wildfowl on the Exe Estuary.
In the subject area of conservation and ecology, human disturbance is classified as any anthropogenic activity that elicits a response in an animal that would otherwise not occur under non-human related conditions. When this change in behaviour negatively impacts an animal’s energy budget it has …

The effects of human disturbance on the seabirds and seals at sub-Antarctic Marion Island
… at Marion Island can be affected by logistic disturbance (especially helicopter noise), incidental pedestrian disturbance and research disturbance. The responses of wandering albatrosses (Diomedea exulans) and king penguins (Aptenodytes patagonicus) were investigated through standardised …

Physiological, Behavioral and Reproductive Responses of Black -Capped Vireos and White -Eyed Vireos to Human Disturbance
I conducted research on effects of human activity on a federally-listed endangered bird species, the Black-capped Vireo (Vireo atricapilla ) and a closely related congeneric, the White-eyed Vireo ( Vireo griseus) on Fort Hood Military Reservation, Texas. My research determines effects of human …

Human-animal interaction in the Antarctic: an animal behaviour approach to human disturbance of penguin colonies
Human disturbance of Antarctic penguins is an important aspect of Antarctic conservation. It is a phenomenon which has raised concern for several decades, and has prompted the creation of guidelines for human behaviour which aim to minimise disturbance to these and other Antarctic animals. …

Impact of Human Disturbance on the Behavior and Physiology of the Endangered Ringed Sawback Turtle (Graptemys oculifera)
… as hunting and pollution, unintentional indirect human disturbance affects poikilothermic turtles by disrupting thermoregulatory basking behavior. In this thesis I assess the behavioral and physiologic impacts of high boat traffic, reductions of basking structures, and environmental factors on …

The changing face of Andean peatlands: the effects of climate and human disturbance on ecosystem structure and function
… temperatures and increasing nutrient inputs from human activities can accelerate decomposition rates in the soil transforming peatlands from sinks to sources of carbon, and reducing their ability to regulate the local hydrological cycles. To identify how rising temperatures and increasing human …

Human disturbance impact on shorebirds at Muizenberg Beach, South Africa, during and prior to the COVID-19 lockdown
The impact of humans on the natural environment has been so extensive that the scientific community has defined a new geological era: the Anthropocene. Coastal ecosystems rank amongst the most threatened of global habitats due to high urban human population density and demand for socio-ecological …
