Abstract River deltas globally are highly exposed and vulnerable to natural hazards often over-exploited landforms. The Global Delta Risk Index (GDRI) was developed assess multi-hazard risk in river support decision-making reduction interventions delta regions. Disasters have significant impacts on the progress towards Sustainable Development Goals (SDGs). However, despite strong interlinkage between disaster sustainable development, global frameworks still isolation actions address them...

Recent research suggests that repeated assays of behaviour, conducted both within and across situations, could reveal important insights into two traditionally distinct areas study: animal personality individual differences in behavioural plasticity. However, at present relatively few studies such data, consider how changing abiotic conditions affect Individual metabolic rate have been suggested as a proximate mechanism promoting personality, leading one to speculate sensitivity temperature...

Observations of coral-reef fish larvae have revealed remarkably consistent orientation behaviour while swimming offshore, requiring large-scale cues. However, the mechanisms underlying this are still being investigated. One potential cue for is Earth's geomagnetic field. Here, we examined effect magnetic field manipulations on during pelagic larval phase. In absence visual cues, individual responded to a 90 deg shift horizontal component within Helmholtz coil with comparable in orientation,...

It is often suggested that due to climate and environmental policy changes, the risk from tick-borne disease increasing, particularly at geographical limits of vector distribution. Our project aimed determine whether this was true for Lyme borreliosis in Ireland which western-most limit Ixodes ricinus, European Borrelia burgdorferi sensu lato. The availability a historical data set tick infection rates compiled 1990s represented unique opportunity as it provided baseline against current...

Abstract Background Pediculosis in cattle causes significant itching, irritation and stress to the animal, often resulting skin damage poor coat condition. The control of bovine pediculosis Ireland is based predominantly on commercial insecticides belonging one two chemical classes, synthetic pyrethroids macrocyclic lactones. In recent years, pyrethroid tolerance has been reported a number species livestock lice United Kingdom Australia. Results this pilot survey, were detected 16 (94%) out...

Despite the economic importance of grass-based livestock production in Ireland and fact that many veterinarians farmers regard tickborne fever (TBF) as an increasingly important disease, especially sheep, little is currently known about prevalence genetic diversity its causative agent, Anaplasma phagocytophilum. In present study, 1376 nymphal Ixodes ricinus ticks collected from woodland, farmland, bog limestone pavement habitats were screened for A. phagocytophilum using TaqMan PCR. Positive...

The parasite, Babesia divergens causes redwater fever in cattle and a rare, albeit life-threatening disease humans. In Ireland, B. has always been considered an important pathogen as the high incidence of precluded areas country from farming. Moreover relatively large proportion human cases were reported here. Red deer (Cervus elaphus), which often harbour babesias that are genetically very similar (if not identical) to divergens, quite widespread. this study 1369 nymphal Ixodes ricinus...
