The noble false widow Steatoda nobilis: Ecology, venom and potential medical importance
(NUI Galway, 2020-08-21)The noble false widow spider Steatoda nobilis (Thorell, 1875) has expanded its range globally in recent years and may represent a potential threat to native ecosystems and public health. Our data shows that S. nobilis is ... -
Novel methods of benthic habitat assessment in designated waterbodies around Ireland
(2017-01-06)The European Union has implemented some of the most progressive conservation Directives in the world. These Directives are implemented in different ways, have different reporting cycles and use unique terminologies. The ... -
Regulation of Six1 and Eya1 during the formation of the preplacodal ectoderm in xenopus - towards a gene regulatory network of the developing neural plate border
(2017-01-06)Cranial placodes are ectodermal thickenings in vertebrate embryos that give rise to many sense organs and ganglia. All placodes arise from a common precursor, the pre-placodal ectoderm (PPE). The latter develops during ... -
Reproductive biology and growth of Ballan Wrasse Labrus Bergylta in west of Ireland waters
(2015-08-15)The research undertaken is very relevant to the aquaculture industry and fisheries management as it addresses natural cycle of the reproductive parameters including sex hormones, gonads development and nutritional background. ... -
Reptiles in Souss-Massa National Park: Diversity, habitat suitability and ecological niche modelling
(NUI Galway, 2024-02-08)The reptiles of Souss-Massa National Park (SMNP) hold great ecological value, yet remain relatively understudied. This thesis aims to advance our knowledge of reptiles and generate conservation-related data. The thesis's ... -
The role of Eya1 in otic neurogenesis in Xenopus laevis
(NUI Galway, 2021-07-26)Cranial placodes are specialized areas of thickening of the early embryonic ectoderm at the head and give rise to sensory organs and ganglia. In vertebrates, the inner ear is derived from one of these placodes, the otic ... -
Spawning migration of Atlantic salmon (Salmo salar) in a regulated river
(NUI Galway, 2018-04-24)Atlantic salmon (Salmo salar) are an iconic species that undertake arduous migrations between marine and freshwater habitats to complete their life-cycle. Populations of Atlantic salmon are in decline across their range ... -
Studies on downstream migrating silver-phase European eels (Anguilla anguilla) in hydropower-regulated rivers
(NUI Galway, 2020-09-29)Within the last 50 years, the European eel has gone from one of the largest freshwater fisheries resources throughout its range to being listed as critically endangered. A variety of factors have been implicated in this ... -
Taxonomy, diversity, and habitat ecology of Irish tardigrades
(NUI Galway, 2022-08-30)Tardigrades (phylum Tardigrada Doyère, 1840) are obligate aquatic, microscopic animals that inhabit marine and freshwater habitats, as well as the terrestrial environment. They occur in limnoterrestrial settings including ... -
Tools to examine population maturity and diet of Nephrops norvegicus on Irish fishing grounds
(NUI Galway, 2021-01-11)The research presented within this thesis describes investigations on maturity and feeding ecology of Nephrops across some Irish and Scottish grounds in the Northeast Atlantic Ocean. This thesis aimed to address the gaps ... -
An unexpected role for Nanos in cnidarian neural stem cell fate determination
(2012-09)The mechanisms of lineage commitment and acquiring specific cell fate remain obscure and require investigating the role of particular genes involved in these complex processes. To address this issue, I studied the role of ... -
The Wnt gene family in evolution and development: insights from Chilopoda
(2012-12-20)The importance of a relatively small number of highly conserved genes and signalling systems, which can be co-opted to many developmental functions over evolutionary time, is a central finding in the field of evolutionary ... -
Wnt signalling in the hydrozoan Hydractinia echinata
(2013-09-11)Canonical Wnt signalling controls many developmental processes in metazoans including primary axis formation in embryonic development and stem cell decision making. The evolutionary history of Wnt signalling and its ancestral ...
