Bayesian stable isotope mixing models
(2013)In this paper, we review recent advances in stable isotope mixing models (SIMMs) and place them into an overarching Bayesian statistical framework, which allows for several useful extensions. SIMMs are used to quantify the ... -
Benthic habitat mapping in the southern Irish Sea
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Habitat mapping is an extremely important area in marine science. Before we can conserve areas or consider the potential impacts of industries such as fishing, aggregates, windfarms and wave or tidal turbines, we first ... -
Best practices for use of stable isotope mixing models in food web studies
(2014)Stable isotope mixing models are increasingly used to quantify consumer diets, but may be misused and misinterpreted. We address major challenges to their effective application. Mixing models have increased rapidly in ... -
Biophysical stimuli induced by passive movements compensate for lack of skeletal muscle during embryonic skeletogenesis
(2011)In genetically modified mice with abnormal skeletal muscle development, bones and joints are differentially affected by the lack of skeletal muscle.We hypothesise that unequal levels of biophysical stimuli in the ... -
Body size evolution in mammals: complexity in tempo and mode
(University of Chicago Press, 2010)Body size correlates with virtually every aspect of species? biology, so understanding the tempo and mode of its evolution is of key importance in macroecology and macroevolution. Here we use body-mass data from 3473 of ... -
Building on IUCN regional red lists to produce lists of species of conservation priority: A model with Irish bees
(Society for Conservation Biology, 2007)A World Conservation Union (IUCN) regional red list is an objective assessment of regional extinction risk and is not the same as a list of conservation priority species. Recent research reveals the widespread, but incorrect, ... -
Cellular inhibitor of apoptosis (cIAP1) is down-regulated during retinal ganglion cell (RGC) maturation.
(Elsevier, 2010)Apoptosis, is the main type of cell death that occurs in ageing and neurodegenerative disease, such as glaucoma. This study therefore characterises the expression profile of caspases (pro-apoptosis) and inhibitors of ... -
Cerebral toxocariasis: Silent progression to neurogenerative disorders?
(2015)Toxocara canis and T. cati are highly prevalent nematode infections of the intestines of dogs and cats. In paratenic hosts, larvae do not mature in the intestine but instead migrate through the somatic tissues and organs ... -
Changing social groups in zoo populations
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)Changes in social groups of animals in zoos occur frequently, and group structures can be changed in a variety of ways: introductions of animals, removals of animals, births and deaths. Information on procedures used to ... -
A colony-level response to disease control in a leaf-cutting ant
(Springer Verlag, 2002)Parasites and pathogens often impose significant costs on their hosts. This is particularly true for social organisms, where the genetic structure of groups and the accumulation of contaminated waste facilitate disease ... -
A common tendency for phylogenetic overdispersion in mammalian assemblages
(The Royal Society, 2008)Competition has long been proposed as an important force in structuring mammalian communities. Although early work recognised that competition has a phylogenetic dimension, only with recent increases in the availability ... -
Community structure and recruitment of decapods in shallow sub-littoral habitats
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)Although decapod crustaceans represent a major component of benthic fauna in many geographic localities around the world, little is known of their early benthic life history. This study examined the relative influences ... -
Community study of toxoplasma antibodies in urban and rural schoolchildren aged 4 to 18 years.
(BMJ Publishing Group, 1997)To estimate the prevalence of toxoplasma antibodies in schoolchildren and their association with clinical and environmental data, antibody titres were measured in 1276 children aged 4 to 18 years attending primary and ... -
A comparison of helminth infections as assessed through coprological analysis and adult worm burdens in a wild host
(2018)Coprological analysis is the most widely used diagnostic tool for helminth infection in both domestic and wild mammals. Evaluation of the efficacy of this technique is rare, due to the lack of availability of adult worm ... -
Comparison of the macroparasite communities of stocked and wild trout (Salmo trutta) from the West of Ireland
(2002)The aim of the present study was to compare the helminth infra and component communities of wild and stocked brown trout in Lough Feeagh, in the west of Ireland, and also to examine the establishment and development of ... -
Condition-dependent expression of virulence in a trypanosome infecting bumblebees
(Blackwell, 2000)Parasite virulence affects both the temporal dynamics of host-parasite relationships and the degree to which parasites regulate host populations. If hosts can compensate for parasitism, then parasites may exhibit ... -
Contamination of the hair of owned dogs with the eggs of Toxocara spp
(2010)Toxocara canis is one of the most common gastrointestinal helminthes of dogs. Humans can become infected through ingestion of infective eggs, Infection often causes few symptoms but in rare cases blindness can occur. It ... -
Cooperation and the evolution of intelligence
(2012)The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions ... -
Cooperation creates selection for tactical deception.
(2013)Conditional social behaviours such as partner choice and reciprocity are held to be key mechanisms facilitating the evolution of cooperation, particularly in humans. Although how these mechanisms select for cooperation ... -
Defining disturbance in time : the ecological implications of varying temporal patterns of disturbances
(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 ...
