Defining disturbance in time : the ecological implications of varying temporal patterns of disturbances
Molinos, Jorge García (Trinity College (Dublin, Ireland). Department of Zoology, 2010)Prediction and mitigation of the effects of global environmental change rely primarily on our capacity to anticipate its causes and consequences. Key to this is the ability to identify and understand the mechanisms that ... -
The ecology and evolution of endemic shrimp in Lake Tanganyika
KAMERMANS, MARJOLEIN (Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)An exceptionally diverse group of shrimp species in the genera Atyella, Caridella, Limnocaridina and Macrobrachium is found in Lake Tanganyika, Africa, while the region is otherwise relatively poor in shrimp species. In ... -
Facing multiple challenges at range margins : influence of climate change, nutrient enrichment and an introduced competitor on the glacial relict, Mysis Salemaai
Penk, Marcin Rafaƚ (Trinity College (Dublin, Ireland). Department of Zoology, 2013)Anthropogenic climate change is arguably the most important threat to global biodiversity, and its effects are expected to escalate. Mechanisms operating at local scales remain poorly understood, likely because of the ... -
The important of parasites in the functioning of warming ecosystems
WILLIAMS, MAUREEN (Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)Parasites play a critical role in the structure and functioning of ecosystems, contributing to overall ecosystem stability and the provision of ecosystem services. As the global climate changes, it is of considerable ... -
The stability of ecosystems under global environmental change
Ross, Samuel Robert (Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2022)Through global environmental change, humans are modifying the planet at an unprecedented rate and scale, triggering the ongoing biodiversity and climate crises. Ecological stability and the consistency of nature s contributions ... -
Temperature and the ecophysiology of marine ectotherms
Harding, Lucy (Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)Temperature influences the physiology, behaviour, and distribution of organisms and the field of thermal ecology has been stimulated in recent decades by the need for a greater understanding of how climate change will ... -
The effects of increased sediment load on the Biota of Lake Tanganyika, East Africa
Donohue, Ian (Trinity College (Dublin, Ireland). Department of Zoology, 2002)Before the work described in this thesis, no studies had been done to test the direct effects of increased sediment load on the biota of Lake Tanganyika. The aim of this research was to assess the effects of increased ... -
Understanding variation in ecology and physiology of marine migratory species.
Bortoluzzi, Jenny Rose (Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)As the world faces the threats of multiple compounded and worsening crises, scientists are racing to gather the knowledge necessary to safeguard entire ecosystems and species. Technological advances are continuously ... -
Water level fluctuations and their effects on lake ecology
Evitmova, Vesela Vasileva (Trinity College (Dublin, Ireland). Department of Zoology, 2013)Escalating freshwater demand, triggered by population and economic growth, technological development, urbanization, land conversion and intensification of agriculture is one of the major challenges facing humankind. The ...
