Quantifying the tolerance of chick hip joint development to temporary paralysis and the potential for recovery
(2021)Background: Abnormal fetal movements are implicated in joint pathologies such as arthrogryposis and developmental dysplasia of the hip (DDH). Experimentally induced paralysis disrupts joint cavitation and morphogenesis ... -
Queen-controlled sex ratios and worker-reproduction in the bumble bee Bombus hypnorum, as revealed by microsatellites
(Blackwell, 2003)Social insect colonies provide model systems for the examination of conflicts among parties with different genetic interests. As such, they have provided the best tests of inclusive fitness theory. However, much remains ... -

Reconceptualising Eco-tourism: Aligning Tourism and Conservation Goals using Biodiversity Perception, Governance, and Management
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, Trinity College Dublin, School of Natural Sciences, 2024)This thesis represents an in-depth exploration of the intricate relationship between tourism and conservation, delving into the critical need for robust governance to ensure effective environmental management within the ... -
Reduced helminth parasitism in the introduced bank vole (Myodes glareolus): More parasites lost than gained.
(2016)Introduced species are often less parasitised compared to their native counterparts and to ecologically similar hosts in the new environment. Reduced parasitism may come about due to both the loss of original parasites and ... -
The regulation of Krox-20 expression reveals important steps in the control of peripheral glial cell development.
(Company of Biologists, 1996)The zinc finger transcription factor gene Krox-20 is expressed in Schwann cells and is required for the myelination of peripheral nerves. We show that the regulation of Krox-20 expression in peripheral glial cells reveals ... -
The relationship between three intensity levels of Toxocara canis larvae in the brain and effects on exploration, anxiety, learning and memory in the murine host
(2001)Outbred LACA mice were administered low (100 ova), medium (1000 ova), high (3000 ova) and trickle (4?250 ova) doses of Toxocara canis ova and the effect of infection was examined with respect to the number of larvae recovered ... -
Reproductive biology including evidence for superfetation in the European badger Meles meles (Carnivora: Mustelidae).
(2015)The reproductive biology of the European badger ( Meles meles ) is of wide interest because it is one of the few mammal species that show delayed implantation and one of only five which are suggested to show superfetation ... -
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 ... -
The role of Intelectin-2 in resistance to Ascaris suum lung larval burdens in susceptible and resistant mouse strains
(2011)The underlying mechanism of predisposition to Ascaris infection is not yet understood but host genetics are thought to play a fundamental role. We investigated the association between the Intelectin-2 gene and resistance ... -

Serum concentrations of carboxyl-terminal propeptide of type I procollagen, amino-terminal propeptide of type III procollagen, cross-linked carboxl-terminal telopeptide of type I collagen, and their interrelationships in schoolchildren
(American Association for Clinical Chemistry, 1997)We report pediatric age- and sex-specific 95% reference intervals for procollagen type I C-terminal propeptide (PICP), the cross-linked C-terminal telopeptide of type I collagen (ICTP), and procollagen type III N-terminal ... -
Serum crosslaps: pediatric reference intervals from birth to 19 years of age
(American Association for Clinical Chemistry, 2002)During childhood growth, bone undergoes extensive modeling involving separate osteoblastic and osteoclastic processes. Markers of bone formation and resorption circulate at higher concentrations in children than in adults, ... -
Short-term foetal immobility temporally and progressively affects chick spinal curvature and anatomy and rib development
(2019)Congenital spine deformities may be influenced by movements in utero, but the effects of foetal immobility on spine and rib development remain unclear. The purpose of the present study was to determine (1) critical time-periods ... -
The significance of cerebral toxocariasis: a model system for exploring the link between brain involvement, behaviour and the immune response
(2013)Toxocara canis is a parasitic nematode that infects canines worldwide, and as a consequence of the widespread environmental dissemination of its ova in host faeces, other abnormal hosts including mice and humans are exposed ... -
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 ... -
Small islands and large biogeographic barriers have driven contrasting speciation patterns in Indo-Pacific sunbirds (Aves: Nectariniidae)
(2022)Birds of the Indo-Pacific have provided biologists with many foundationalinsights. This study presents evidence for strong phylogeographic structure in two sunbird species from the heart of this region, the olive-backed ... -
Snake venom potency and yield are associated with prey-evolution, predator metabolism and habitat structure
(PubMed Central, 2019)Snake venom is well known for its ability to incapacitate and kill prey. Yet, potency and the amount of venom available varies greatly across species, ranging from the seemingly harmless to those capable of killing vast ... -
Soil-transmitted helminth infections in Nigerian children aged 0-25 months
(2009)The objective of this cross-sectional study was to determine the prevalence and intensity of soil-transmitted helminths (STHs) in children aged 0?25 months and to identify the associated risk factors for Ascaris lumbricoides ...
