Humpback Whale ( Megaptera novaeangliae ) Site Fidelity, Residency, and Movement Patterns in Ireland Based on Citizen Science DataNARA Subscribed
Understanding the residency and movement patterns of large cetaceans like the humpback whale is crucial for effective conservation. In Ireland, the Irish Whale and Dolphin Group has been collecting humpback whale data since the 1990s, primarily through citizen science. This collective effort has contributed to the creation of the Irish Humpback Whale Photo‐identification Catalogue. Using this dataset, we assessed humpback whal...
Animal morphometrics are essential for understanding a species’ life history and its ecological interactions with the environment. This study investigates the maturity status and body condition of humpback whales ( Megaptera novaeangliae ) across understudied areas of the Northeastern Atlantic Ocean. Uncrewed Aerial Systems (UAS or drones) were used to collect photogrammetry data from humpback whales in Ireland, Norway, and Ca...
Copper-based fungicide application shifts the soil bacterial community structure and the soil nitrogen cycleNARA Subscribed
Purpose Through high sorption affinities of Copper (Cu) to soil organic matter, excessively applied Cu generates complex responses by numerous soil functions, e.g. microbial nutrient cycling, that are relying on organic matter decomposition. Methods Effects of Cu on soil nitrogen (N) transformation were investigated on a bacterial community level with complying N-functional genes, enzymatic activities and N-pools. Up to 5000 m...
Extending effectiveness to efficiency: Comparing energy and environmental assessment methods for a wet cooling towerNARA Subscribed
Improving the environmental performance and energy efficiency of cooling towers requires systematic evaluation. However, methodological challenges emerge when applying typical environmental assessment methods to cooling towers. Hence, this paper compares the methods, analyzes their strengths and weaknesses, and proposes adaptions for evaluating cooling towers. As a case study, we applied five methods for assessing the wet cool...
Extensive regional variation in the phenology of insects and their response to temperature across N orth A mericaNARA Subscribed
Climate change models often assume similar responses to temperatures across the range of a species, but local adaptation or phenotypic plasticity can lead plants and animals to respond differently to temperature in different parts of their range. To date, there have been few tests of this assumption at the scale of continents, so it is unclear if this is a large‐scale problem. Here, we examined the assumption that insect taxa...
Cycle Development in a Mini-Freeze Dryer: Evaluation of Manometric Temperature Measurement in Small-Scale EquipmentNARA Subscribed
The objective of this research was to assess the applicability of manometric temperature measurement (MTM) and SMART™ for cycle development and monitoring of critical product and process parameters in a mini-freeze dryer using a small set of seven vials. Freeze drying cycles were developed using SMART™ which automatically defines and adapts process parameters based on input data and MTM feedback information. The freeze drying...
Clear cell chondrosarcoma in Von Hippel-Lindau diseaseNARA Subscribed
A diagnosis of clear cell chondrosarcoma of the ulna was made in a patient with Von Hippel-Lindau disease (VHL). After surgery, genetic analysis of the tumor tissue showed loss of heterozygosity at the VHL gene locus. Immunohistochemical analysis confirmed loss of expression of the VHL protein in the tumor cells. In addition, abundant Cyclin D1 expression in the tumor was observed. Chondrosarcoma has been described before in a...

The role of parasite‐driven selection in shaping landscape genomic structure in red grouse ( Lagopus lagopus scotica )NARA Subscribed
Landscape genomics promises to provide novel insights into how neutral and adaptive processes shape genome‐wide variation within and among populations. However, there has been little emphasis on examining whether individual‐based phenotype–genotype relationships derived from approaches such as genome‐wide association (GWAS) manifest themselves as a population‐level signature of selection in a landscape context. The two may pro...
