Ireland's central source for Open Access health research
Lenus, the Irish Health Research repository is the leading source for Irish research in health and social care. The Lenus collections include peer reviewed journal articles, grey literature, dissertations, reports and conference presentations. Lenus contains the publications of the Irish Health Service Executive (HSE) and the collected research output of over 130 health organisations past and present are all freely accessible.
Submit Your Research to Lenus
If you are an Irish researcher or have conducted research in an Irish institution or health organisation, you can add your published research to Lenus. Submitted articles must be available in Open Access format or the publisher's policy must permit author self archiving. Advice on Open Access publishing and publishers' policies is available on the 'Open Access Publishing Guide' and 'Publishers' policies' pages available on the left-hand menu.
Authors and researchers – have you applied for an ORCID?
ORCIDs are a form of persistent unique identifier that gather all your published research together and link it unambiguously with you. Having an ORCID means eliminating confusion with similarly-named authors, and allows you to list all past affiliations, funding details and publications. Click here to get your free ORCID today.

Scorpion Species with Smaller Body Sizes and Narrower Chelae Have the Highest Venom Potency.Scorpionism is a global health concern, with an estimation of over one million annual envenomation cases. Despite this, little is known regarding the drivers of scorpion venom potency. One widely held view is that smaller scorpions with less-developed chelae possess the most potent venoms. While this perception is often used as a guide for medical intervention, it has yet to be tested in a formal comparative framework. Here, we use a phylogenetic comparative analysis of 36 scorpion species to test whether scorpion venom potency, as measured using LD50, is related to scorpion body size and morphology. We found a positive relationship between LD50 and scorpion total length, supporting the perception that smaller scorpions possess more potent venoms. We also found that, independent of body size, scorpion species with long narrow chelae have higher venom potencies compared to species with more robust chelae. These results not only support the general perception of scorpion morphology and potency, but also the presence of an ecology trade-off with scorpions either selected for well-developed chelae or more potent venoms. Testing the patterns of venom variations in scorpions aids both our ecological understanding and our ability to address the global health burden of scorpionism.
