Abstract:

Habitat loss is the primary driver of global amphibian declines and thus preserving habitat is our best hope for preserving species at risk. The habitat needs of amphibians are complex due to terrestrial and aquatic requirements throughout their life history. Many pond breeding amphibians spend the majority of their life cycle within terrestrial environments and thus terrestrial habitats are critical to their persistence. Cryptic and fossorial behavior makes observations of amphibians in terrestrial habitats difficult. Our knowledge of the terrestrial ecology of amphibians is therefore incred

Conservation managers worldwide are increasingly faced with the challenges of managing and protecting fragmented landscapes, largely as a consequence of human activities. Over recent decades, ecological theory has made a significant contribution to the development of landscape-scale conservation and practice. However, recommendations accounting for what is practically achievable in the modern-day landscape are currently lacking, while criteria for conservation planning and prioritisation continue to neglect the role of habitat networks at the required spatial scale for the long-term persistenc

Abstract:

Understanding the evolutionary processes underlying extant biodiversity may help us to comprehend why species richness is not equally distributed between clades. One of the main causes to explain the disparity of species richness is the development of key innovations in particular clades, increasing or decreasing their capabilities to occupy new environments, to exploit novel resources or to cope with competition. The present thesis focuses on explaining the macroevolutionary consequences of two of the most common habitat transitions in aquatic environments: between environments with different

Ecologists have long known that complex habitats often provide prey with refugia from predation in a wide variety of habitat types and for a wide variety of prey species. Despite the recognized importance of structural habitat complexity, ecologists have measured complexity in many different ways. I propose four new indices of structural habitat complexity that are dimensionless, that can be applied across various habitat types and scales, and that directly measure how structural complexity interferes with a predator's foraging ability. These indices are: (1) Ct/At, the total area of cover wit

<p> Maintaining intraspecific variation is important for populations’ long-term success and is increasingly being recognized as an important conservation goal.

The aspidochirote sea cucumber Australostichopus mollis is a commercially valuable species of research interest as a candidate for aquaculture or polyculture. Understanding juvenile habitat and feeding biology is essential to furthering aquaculture efforts and expanding knowledge of the ecology of the species. Surveying within the Mahurangi Harbour, New Zealand, revealed highly patchy distribution of juvenile A. mollis at one site within an area of high adult density. High juvenile density correlated with sediment qualities favouring epibenthic detritivorous deposit-feeding. Juvenile A. mollis

<p> Non-habituated coyotes (<i>Canis latrans</i>) avoid direct interactions with humans. Reliance on human food sources has been linked to gradual habituation, a precursor to conflict and attacks on domestic pets and humans.

Local urban coyotes are relying predominately on natural foods, with an increase in mammalian prey in the wet season and an increase in vegetation and insect consumption in the dry sea

Habitat use is a key component to understanding the conservation needs of species. While an array of quantitative analyses for studying fine-scale habitat use and selection have been developed, such methods have rarely been applied to bat species, with most work focused at a broad scale or using qualitative methods. Insectivorous bat communities face major threats from habitat conversion, exploitation of natural resources, and the impending spread of white-nose syndrome. Hence, detailed knowledge of their habitat needs is critical for developing effective management plans. In North Dakota, lit

Furthermore, changes in the landscape matrix and land-use intensification within remaining natural areas can reduce habitat quality and exacerbate the consequences of habitat loss and fragmentation. Accordingly, wildlife conservation requires an understanding of how landscape structur

Among British birds, a number of woodland specialists have undergone a serious population decline in recent decades, for reasons that are poorly understood. The Marsh Tit is one such species, experiencing a 71% decline in abundance between 1967 and 2009, and a 17% range contraction between 1968 and 1991. The factors driving this decline are uncertain, but hypotheses include a reduction in breeding success and annual survival, increased inter-specific competition, and deteriorating habitat quality.
