Canada’s boreal zone covers almost 60% of Canada’s landmass. It has large areas of peatlands where black spruce is the most common tree species, which rarely reaches merchantable size. Tree biomass is usually estimated using allometric equations with diameter at breast height (DBH) used as a predictor. While such allometric relationships are well-established for merchantable trees, predicting biomass for the sub-merchantable t...
Seagrass beds provide essential habitat for many fish species. This study utilized over a decade (2009 to 2022) of annual seagrass monitoring data to investigate trends in seagrass composition with the introduction of the non-native species, Halophila stipulacea . Fish community surveys, as well as benthic community surveys, were also conducted within soft bottom habitat of two Caribbean bays in 2023. Seagrass composition saw...
Niche Expansion in an Invasive Plant Has Significant Influence on the Modelling of Its Current and Future Geographic DistributionsNARA Subscribed
Aim Species distribution models (SDMs) are commonly used to predict distributions of invasive species; however, they rely on assumptions that often go untested for invasive species. To determine what climatic conditions may be suitable for invasion using SDMs, it is critical to assess whether the species occupies the same climatic niche in its native and invaded ranges. If this assumption is not met, current distribution‐clima...
Distributed optical fibre sensing (DOFS) is a technology that enables continuous, real-time measurements of a range of environmental parameters along the length of a fibre optic cable. In this article, we review the recently emerged applications of DOFS techniques in physical oceanography and offer a perspective on the technology's potential for future growth within the field. The introduction of DOFS to physical oceanography...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Local and Landscape‐Level Environmental Conditions Drive Habitat Selection Across Terrestrial Mammal SpeciesNARA Subscribed
Aim Animal movements are a fundamental process affecting communities and ecosystems. Quantifying habitat selection across species and habitats is key for understanding how animals respond to environmental change. Currently, we lack comparative studies that examine how habitat selection varies across species traits and landscapes. We aim to quantify global patterns of habitat selection to help understand the fundamental drivers...
Ineffectiveness of topical antibiotics in treating Acropora spp. affected by white diseasesOA Marine
For many decades, white band disease (WB) and white pox disease (WPX) have been severely impacting populations of the reef building corals Acropora palmata and A. cervicornis throughout the Caribbean region. Even after the major outbreaks in the 1990s and early 2000s, these diseases still occur annually in certain regions of the Caribbean, including in the United States Virgin Islands (USVI). Given the high virulence and infec...

Exploring the Efficacy of Multivariate Air Masses as a Predictor of Electricity Demand: A Case Study in the Northeastern United StatesNARA Subscribed
In many midlatitude regions, human thermal comfort and electricity demand are strongly linked via the use of heating and air conditioning. Human biometeorological research has shown that the relationship between humans and their thermal comfort is quite complex, and a multitude of different thermal comfort metrics have been developed to examine it. Based upon prior research that has shown air masses (AMs) influence human therm...
Changing bryozoan fauna in Otago Harbour reflects growing urbanisation and globalisationNARA Subscribed
A comparison between historic reports dating from 1884 (78 records of 35 species) to the bryozoan fauna present today (98 colonies of 14 species) reveals considerable faunal change in Otago Harbour / Te Wai Ōtākou (45° 50'S 170° 38'E) in Dunedin, east coast of South Island, Aotearoa New Zealand. This highly‐modified urban port was once a rock‐edged tidal inlet surrounded by bush and grassy hills, but changes to its flora and f...
Site-specific variability in recovery of Caribbean sponge communities following two category-5 hurricanesNARA Subscribed
Coral reefs worldwide are increasingly subjected to multiple disturbances, including storm events, thermal anomalies, disease outbreaks and more localized stressors. Climate change is predicted to increase the frequency and severity of tropical cyclones. In 2017, an unprecedented event of two Category 5 hurricanes in rapid succession occurred on St. Thomas, United States Virgin Islands. Short-term monitoring (2.5 months after...
Invasive predatory fish occupies highest trophic position leading to expansion of isotopic niches in a riverine food webNARA Subscribed
Invasive species are drivers of ecological change with the potential to reshape the structure and function of terrestrial and aquatic ecosystems. The invasive flathead catfish ( Pylodictis olivaris ) is an opportunistic predator that has established a rapidly growing population in the Susquehanna River, Pennsylvania, USA, since they were first detected in 2002. Although the predatory effects of invasive catfishes on native fis...
Hyperpigmented melanistic lesions (HPMLs) are a visual anomaly documented on the skin of smallmouth bass Micropterus dolomieu in the Susquehanna River Basin, Pennsylvania and in numerous other geographical locations. Currently, there is a lack of information on environmental and fish characteristics that may influence the prevalence of HPMLs associated with a recently described Adomavirus . The goal of this study was to unders...
