Macroevolution with living and fossil species
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Although many biodiversity studies focus on living species, the vast majority of species that ever lived are long extinct. It is therefore crucial to combine data from both living and fossil species to fully understand ... -
Mechanoregulation of joint morphogenesis : investigating the role of muscle induced mechanical forces in the regulation of differentiation and growth in the avian knee joint
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Muscle induced mechanical forces have been implicated as an important regulator in the development of the skeleton. Immobilisation studies have demonstrated that in the absence of muscle contraction, skeletal elements are ... -
Modelling the impact of two intertidal primary consumer mollusc species on microphytobenthic biomass
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)As many marine intertidal benthic primary consumers are relatively small in body size, their individual impact on the environment is generally negligible. The combined influence of the extremely high numbers of individuals ... -
Morphological and DNA barcoding-based studies of meiofauna community variation along the salinity gradient and response to environmental quality changes within Irish transitional waters
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)The primary focus of this thesis is to identify the changes in meiofauna community structure in response to the estuarine salinity gradient. This was achieved through morphological identification of the nematode phylum to ... -
Morphological change in nucleus accumbens neurons as a basis for the development of haloperidol-induced movement disorders
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)A syndrome of involuntary, hyperkinetic abnormal movements called tardive dyskinesia (TD) develop in predisposed individuals following treatment and withdrawal from neuroleptic drugs. These movements are primarily orofacial ... -
Neurotrophin mRNA expression in the central nervous system of the brain stem-spinal cord regenerating model, Anguilla anguilla, the European eel
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)Neuronal regeneration is extremely limited in the central nervous system (CNS) of mature amniotes. On the other hand, many anamniotes, such as some fish, display rapid morphological and functional recovery after CNS injury, ... -
New diagnostic and prognostic biomarkers for age-related macular degeneration
(Trinity College (Dublin, Ireland). Department of Zoology, 2014)Age-related macular degeneration (AMD) is a common condition causing progressive visual impairment, leading to irreversible blindness. This condition is characterised by loss of central vision attributed to degenerative ... -
Parasites in a host species' invasion : a unique small mammal model system
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)It is becoming increasingly evident that biological invasions result in altered disease dynamics in invaded ecosystems, with knock-on effects for native host communities. Invasive species may acquire native parasites, ... -
Pest control in museums : status of collections and an evaluation of control strategies
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Information on the status of museum collections held in the British Isles suggests that over 25 million specimens are at risk from the effects of deterioration. It is widely acknowledged that this situation is reflected ... -
Plasticity of foraging strategies in the blue tit, Cyanistes caeruleus and the domestic chick, Gallus gallus domesticus
(Trinity College (Dublin, Ireland). Department of Zoology, 2014)This research was primarily concerned with dietary conservatism in wild blue tits, Cyanistes caeruleus. Dietary conservatism refers to the tendency for some individuals of a population to ignore novel foods. Dietary ... -
Population dynamics and biomass of Limapontia depressa at North Bull Island, Dublin Bay
(Trinity College (Dublin, Ireland). Department of Zoology, 2001) -
Quantifying the impacts of multiple stressors on the production of marine benthic resources
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2024)Coastal ecosystems are among the most heavily affected by climate change and anthropogenic activities, which impacts their diversity, productivity and functioning and puts many of the key ecosystem services they provide ... -
Re-Creating Science in Higher Education: Exploring a Creativity Philosophy
(MEd, Trinity College Dublin, 2014) -
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 ... -
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 ...
