<p> Humans introduce non-native plants to new areas at an increasing rate with the increased movement across the globe. These invasive species can become mono-cultures and extremely different from the native floral community. Amphibians, at the same time, are facing global declines with approximately one-third of all amphibians threatened or endangered. Due to the importance of amphibians as prey items for many vertebrates including small birds, mammals, and reptiles, and also predator controls over many invertebrates, including some pest species, the decline of amphibians has large implicat

<p>There have been many cases reported of amphibian populations declining. These are often due to anthropogenic factors such as habitat destruction and pollution. However, some eclines have not had an obvious cause and many of these have been investigated and found to be due to pathogenic disease. Batrachochytrium dendrobatidis is a recently described pathogen of frogs. The population declines that have been associated with chytridiomycosis have occurred in relatively undisturbed areas such as national parks. The declines tend to occur at higher altitudes or in colder climates. This is thought

Tadpole cDNA from different frogs species (X.laevis, Rana temporaria and Rana tigrina) were used during the project.

The introduction (Chapter 1) discusses the importance of islands in the study of evolution and examines patterns of intraspecific variation that have been reported in other Seychelles organisms.

An extraordinary fossil record comprising hundreds of specimens and many ontogenetic stages distinguishes branchiosaurids.

This thesis is about understanding the processes that explain the patterns of extinction risk and declines that we see in amphibians, how we can use that understanding to set conservation priorities, and how we can convert those priorities into practical, hands-on research and management. In particular, I focus on the threat posed by the emerging infectious disease, chytridiomycosis, which is caused by the chytrid fungus, Batrachochytrium dendrobatidis (Bd). Amphibians display a non-random pattern of extinction risk, both taxonomically and geographically. In chapter two I investigate the mecha

Amphibian population decline is a recognised phenomenon spanning at least the last 40 years, and it is likely that a number of factors have contributed, including environmental contamination. Amphibians are vulnerable to agrochemical uptake as they must breed in water, and often spend the aquatic phase of their lifecycle in agricultural water bodies, which may contain a complex mixture of biologically active chemicals. Endocrine disrupting compounds may cause reproductive effects in humans and wildlife, although the link between pesticides and endocrine disruption is largely unknown. Therefore

Amphibians are the most threatened class of vertebrate, and rates of species decline and extinction far exceed those seen historically. Habitat loss, climate change, over-exploitation and emerging infectious disease have all been identified as threatening processes. The trade in amphibians has been implicated in over-exploitation through the harvesting of wild animals, and as an important pathway for the global spread of the fungal pathogen, Batrachochytrium dendrobatidis (Bd). However, there are no analyses of how Bd may spread through the trade chain. This thesis addresses this issue by (1)

Amphibians are declining worldwide in response to pressures that are too numerous, difficult and rapid to ameliorate in the wild before some taxa become extinct. Ex situ conservation, whereby animals are maintained in captivity until threats in the wild have been resolved, is the only means of saving up to five hundred amphibian species. Amongst political, financial and practical hurdles, the most fundamental problem for these programmes is lack of knowledge about how to maintain species successfully in captivity.
