Macroecology and extinction risk correlates of frogs
(Blackwell Publishing, 2008)Aim Our aim was to test whether extinction risk in frogs could be predicted from their body size, fecundity or geographic range size. Because small geographic range size is a correlate of extinction risk in many taxa, we ... -
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 ... -
Mechanical Regulation of Skeletal Development
(University of Edinburgh (datashare), 2013)Development of the various components of a normal skeleton requires highly regulated signalling systems that co-ordinate spatial and temporal patterns of cell division, cell differentiation and morphogenesis. Much work in ... -
Mechanical Stimulation via Muscle Activity is Necessary for the Maturation of Tendon Multiscale Mechanics during Embryonic Development
(2021)During embryonic development, tendons transform into a hypocellular tissue with robust tensile load-bearing capabilities. Previous work suggests that this mechanical transformation is due to increases in collagen fibril ... -
A mechanistic basis for the mechanical regulation of skeletal development
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)Movement is essential to embryonic skeletal development. In humans, Foetal Akinesia Deformation Syndrome results when inhibited movement causes joint contractures and weakened bones susceptible to fracture. Differentiation ... -
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 ... -
Metabolic rate and body size are linked with perception of temporal information.
(2013)Body size and metabolic rate both fundamentally constrain how species interact with their environment, and hence ultimately affect their niche. While many mechanisms leading to these constraints have been explored, their ... -
The migration of Ascaris suum larvae, and the associated pulmonary inflammatory response in susceptible C57BL/6j and resistant CBA/Ca mice
(2007)Ascariasis is an important infection in humans (Ascaris lumbricoides) and pigs (Ascaris suum) and individuals appear to be predisposed to either heavy or light worm burdens. These extremes of susceptibility and resistance ... -
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 ... -
Molecular and Phenotypic Data Support the Recognition of the Wakatobi Flowerpecker (Dicaeum kuehni) from the Unique and Understudied Sulawesi Region
(2014)Accurate estimates of species richness are essential to macroecological and macroevolutionary research, as well as to the effective management and conservation of biodiversity. The resolution of taxonomic relationships is ... -
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 ... -
Mortality rates and division of labour in the leaf-cutting ant, Atta colombica
(2006)Division of labor in social groups is affected by the relative costs and benefits of conducting different tasks. However, most studies have examined the dynamics of division of labor, rather than the costs and benefits that ... -
The multidemsionality of ecological stability
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)Ecological stability is a multifaceted concept, incorporating components such as variability, resistance, resilience, persistence, and robustness. Understanding and predicting the relationships among these many components ... -
A murine model for cerebral toxocariasis: characterisation of host susceptibility and behaviour.
(2006)Toxocara canis, the parasitic roundworm of dogs, can infect a number of paratenic hosts, such as mice and humans, due to the widespread dissemination of its ova in the environment. In these paratenic hosts, larvae have ... -
Natural immunity to Ascaris lumbricoides associated with IgE antibody to ABA-1 allergen and inflammatory indicators in children
(American Society for Microbiology, 1999)Children putatively immune to the large roundworm Ascaris lumbricoides were identified in an area of Nigeria where infection is hyperendemic. Immunity was associated with higher levels of serum ferritin, C-reactive protein, ... -
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 ... -
Ocular toxocariasis in school children
(2004)Ocular toxocariasis in humans is typically a unilateral disease caused by second?stage larvae of the Toxocara species. Serological evidence of widespread infection in humans provides little information on clinical disease. ... -
On the evolution of claustral colony-founding in ants
(Evolutionary Ecology Ltd, 2003)The dispersal and survival of offspring is a key step in an organism?s life history. In ants, the main strategy used to complete this step is known as independent colony-founding. Here, individual young queens leave their ...
