Introduction
Willson Gaul is an ecologist on Saipan, Northern Mariana Islands. Willson obtained a PhD at the Earth Institute, University College Dublin in 2021 for work modelling species distributions with opportunistic biological records. Current research includes acoustic studies of Orthoptera (crickets and katydids), and using automated recording units (ARUs) to monitor sound-producing organisms in remote locations.

Aim Soil arthropods are important decomposers and nutrient cyclers, but are poorly represented on national and international conservation Red Lists. Opportunistic biological records for soil invertebrates are often sparse, and contain few observations of rare species but a relatively large number of non-detection observations (a problem known as cl...

There is an increasing interest in landscape scale perspectives of ecosystem functioning to inform policy and conservation decisions. However, we need a better understanding of the stability of ecosystem functioning (e.g. plant productivity) at the landscape scale to inform policy around topics such as global food security. We investigate the role...

Because birds are frequently detected by sound, autonomous audio recorders (called automated recording units or ARUs) are now an established tool in addition to in-person observations for monitoring the status and trends of bird populations. ARUs have been evaluated and applied during breeding seasons, and to monitor the nocturnal flight calls of m...

We report the millipede Chordeuma sylvestre C. L. Koch, 1847 for the first time from Ireland. We used morphology of male gonopods and DNA barcoding of the COI gene from two individuals to confirm the identification of one male and one female collected from the campus of University College Dublin. DNA barcoding revealed two mitochondrial haplotypes,...

Biological records provide biodiversity information over large spatial and temporal scales. Our systematic scoping review of biological records from the well-recorded region of the United Kingdom (UK) and Ireland revealed that over half of all studies using biological records were studying species distributions (134 of 253 studies) and/ or temporal...
Article
Full-text available
Biological records are often the data of choice for training predictive species distribution models (SDMs), but spatial sampling bias is pervasive in biological records data at multiple spatial scales and is thought to impair the performance of SDMs. We simulated presences and absences of virtual species as well as the process of recording these sp...

To fully understand ecosystem functioning under global change, we need to be able to measure the stability of ecosystem functioning at multiple spatial scales. Although a number of stability components have been established at small spatial scales, there has been little progress in scaling these measures up to the landscape. Remote sensing data hol...

Here I report records of the millipede Ophyiulus germanicus (Verhoeff, 1896) in Dublin. These records extend the known distribution of O. germanicus in Ireland southward from numerous locations near Belfast (Anderson 2019) and are some of the first records from Ireland.

The impact of productivity on species diversity is often studied at small spatial scales and without taking additional environmental factors into account. Focusing on small spatial scales removes important regional scale effects, such as the role of land cover heterogeneity. Here, we use a regional spatial scale (10 km square) to establish the rela...

Wetlands in the Laurentian Great Lakes region are affected by many environmental stressors that affect different organisms in different ways. We introduce an objective, quantitative Index of Ecological Condition (IEC), which uses the occurrences of sensitive species as indicators of ecosystem health. The relationship between species occurrences and...

This project focuses on grassland productivity to investigate if the biodiversity surrounding farm-grasslands promote resilient agricultural productivity. We will use information from satellite images, unmanned aerial drones and experimental plots. We will then produce maps of Ireland that look into the near-future, showing areas where production is riskier when faced with extreme events, such as the conditions that created the fodder crisis of 2012-13.
