Reproductive seasonality of the male and female Eurasian badger, Meles meles
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)The ecology of the Eurasian Badger (Meles meles) is highly diverse; varying greatly between geographical regions, populations and even adjoining groups. It has been argued that mating systems result from individual strategies ... -
The role of helminth parasites in host invasion: a freshwater fish system
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)With the incidence of species invasions set to increase in the coming decades, it is increasingly important that research on invasive species impacts captures the complexity of natural ecosystems, including the influence ... -
Single cell analysis of tail regeneration in Ambystoma mexicanum
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)This present study examined tail regeneration in the Mexican salamander Ambystoma mexicanum, on a single cell level in vivo. The primary aim of this study was to understand where the cells were coming from to replace all ... -
Spatial and temporal variability in the littoral macroinvertebrate communities of selected Irish lakes
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)Five replicate samples were collected from five exposed stony shoreline sites in three low, mid and high alkalinity lakes within a narrow temporal window in order to assess the spatial variation in littoral invertebrate ... -
The stability of ecosystems under global environmental change
(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 ... -
Susceptibility and mortality in honeybees (Apis mellifera) infested with the tracheal mite (Acarapis woodi)
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)The tracheal mite, Acarapis woodi (Rennie), is an obligate parasite of the honeybee. It was first discovered in 1919 by Rennie during his investigation into the widespread deaths of honeybee colonies in Europe in the early ... -
Taxonomy and ecology of epilithic diatoms in Irish lakes
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)Benthic algae are significant primary producers and important in biogeochemical cycling in shallow lakes in particular, but epilithic diatom ecology is poorly understood compared to phytoplankton and higher trophic levels. ... -
Temperature and the ecophysiology of marine ectotherms
(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 ... -
Temporal and spatial dynamics of fisheries discards from Irish waters
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)There is worldwide recognition that fisheries discards (i.e. the portion of the catch returned to sea) are not only a waste of resources but are also responsible for numerous adverse ecological impacts in the marine ... -
The development of a mouse model to explore resistance and susceptibility to early Ascaris suum infection
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Ascaris suum and Ascaris lumbricoides are widespread geohelminths of pigs and humans, respectively, resulting in severe morbidity and possible mortality. The contribution of migrating A. suum larvae to liver damage has ... -
The development of aquatic macroinvertebrate communities in two artificial wetlands on Irish cutaway bog, with particular reference to Corixidae (Hemiptera Heteroptera)
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Two cutaway water bodies in mid-west County Offaly were studied. Turraun, created in 1990/1991, has an estimated area of 52-60 ha and an average depth of 0.5 to 1 m. The wetland sediment is predominantly peat with some ... -
The developmental orgins of Tracheo-oesophageal malformations : investigating the molecular and morphological basis of foregut abnormalities in Adriamycin treated mice and in newly established 3D foregut culture system
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Oesophageal Atresia/Tracheo-oesophageal fistula (OA/TOF) is a congenital malformation that requires urgent and complex surgery soon after birth and is associated with life-long respiratory and gastro-intestinal morbidity. ... -
The diet of the Eurasian badger (Meles meles) in the Republic of Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)After a comprehensive analysis of the diet, the Eurasian badger (Meles meles) in the Republic of Ireland was found to display the foraging behaviour of a generalist forager. This description was considered to be appropriate ... -
The ecology of obligate scavengers from individual behaviour to population dynamics
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Studies on vultures are on the rise, and just as well given the sharp declines in many of the 23 species. Indeed it seems these population crashes are responsible for this research boost. However, there remain obvious gaps ... -
The ecology of Sua pan and its flamingo populations
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)Sua pan is part of the Makgadikgadi saltpan complex, which is derived from an ancient palaeo-lake that once covered much of present-day northern Botswana. Today it is the 'sump' of an endorheic drainage system, into which ... -
The ecology of the family Chydoridae (Branchiopoda, Anomopoda) and its application to lake monitoring
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)Chydorids (Branchipoda, Anomopoda) were sampled from twenty nine Irish lakes between June 1996 and July 1997, in order to assess the usefulness of this group as indicators of lake ecological quality. The lakes represented ... -
The effects of increased sediment load on the Biota of Lake Tanganyika, East Africa
(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 ... -
The epidemiology of Cryptosporidium species in a Nigerian paediatric population
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)Cryptosporidium is an Apicomplexan, protozoan parasite, infecting the gastroepithelium of many vertebrate hosts, including man, and is the causative agent of the diarrhoeal disease cryptosporidiosis. Although infection may ... -
