Capture heats up sharks
(2022)Catch-and-release fishing is an important component of ecotourism industries and scientific research worldwide, but its total impact on animal physiology, health and survival is understudied for many species of fishes, ... -
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 ... -
The consequences of unidentifiable individuals for the analysis of an animal social network
(2015)Social network analysis is pervasive in understanding animal social systems, and provides information about how individuals vary in their social strategies. Many long-term studies comprising uniquely marked individuals ... -
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 ... -
Determination, diversification and multipotency of mammalian myogenic cells
(2008)In amniotes, myogenic commitment appears to be dependent upon signaling from neural tube and dorsal ectoderm, that can be replaced by members of the Wnt family and by Sonic hedgehog. Once committed, myoblasts undergo ... -
Developing bones are differentially affected by compromised skeletal muscle formation
(University of Edinburgh (datashare), 2010)Mechanical forces are essential for normal adult bone function and repair, but the impact of prenatal muscle contractions on bone development remains to be explored in depth in mammalian model systems. In this study, we ... -
The development of a mouse model to explore resistance and susceptibility to early Ascaris suum infection
(2006)Ascaris suum and Ascaris lumbricoides exhibit an over-dispersed frequency distribution in their host populations in both the adult and larval stages. The impact of host factors on this observed distribution is still poorly ... -
Development of an in vitro culture method for cells and tissues from the zebra mussel (Dreissena polymorpha)
(Springer, 2009)Despite the successful transfer of mammalian in vitro techniques for use with fish and other vertebrates, little progress has been made in the area of invertebrate tissue culture. This paper describes the development of ...
