Monthly differences in the movement ecology of lake whitefish ( Coregonus clupeaformis ) in eastern Lake OntarioNARA Subscribed
Lake whitefish are a cold‐water species that holds cultural and economic importance throughout the Great Lakes region. Anthropogenic stressors over the last 60 years (e.g., invasive species, habitat degradation, and pollution) have caused significant declines in their populations. Furthermore, there is limited knowledge on the spatial ecology and habitat use of the species in Lake Ontario. Therefore, we used acoustic telemetry...
A method to identify positive tipping points to accelerate low-carbon transitions and actions to trigger themNARA Subscribed
Meeting the Paris Agreement to limit global warming to “well below 2 °C” requires a radical acceleration of action, as the global economy is decarbonising at least five times too slowly. Tipping points, where low-carbon transitions become self-propelling, could be key to achieving the necessary acceleration. We deem these normatively ‘positive’, because they can limit considerable, inequitable harms from global warming and hel...
A Tale of Two Shrimps—Speciation and Demography of Two Sympatric Shrimp Species From Hydrothermal VentsNARA Subscribed
Hydrothermal vents can serve as natural laboratories to study speciation processes due to their fragmented distribution, often with geographic barriers between habitats. Two sympatric species of Rimicaris shrimps occur at vents on the Izu‐Bonin‐Mariana volcanic arc: Rimicaris loihi also occurs near Hawai’i and R. cambonae is present on the Tonga Arc. These two species biogeographically co‐occur and are genetically similar, rai...

Subsidy accessibility drives asymmetric food web responsesNARA Subscribed
Global change is fundamentally altering flows of natural and anthropogenic subsidies across space and time. After a pointed call for research on subsidies in the 1990s, an industry of empirical work has documented the ubiquitous role subsidies play in ecosystem structure, stability, and function. Here, we argue that physical constraints (e.g., water temperature) and species traits can govern a species' accessibility to resourc...
Non-Linear Device Head Coupling and Temporal Delays in Large Animal Acceleration Models of Traumatic Brain InjuryNARA Subscribed
Accurate characterization of head kinematics following an external blow represents a fundamental aspect of traumatic brain injury (TBI) research. The majority of previous large animal studies have assumed an equivalent relationship between the device delivering the impulsive load and subsequent head kinematics rather than performing direct measurement (sensors or videography). The current study therefore examined factors affec...
The ENIGMA sports injury working group:– an international collaboration to further our understanding of sport-related brain injuryNARA Subscribed
Sport-related brain injury is very common, and the potential long-term effects include a wide range of neurological and psychiatric symptoms, and potentially neurodegeneration. Around the globe, researchers are conducting neuroimaging studies on primarily homogenous samples of athletes. However, neuroimaging studies are expensive and time consuming, and thus current findings from studies of sport-related brain injury are often...
Understanding predator–prey interactions and food web dynamics is important for ecosystem‐based management in aquatic environments, as they experience increasing rates of human‐induced changes, such as the addition and removal of fishes. To quantify the post‐stocking survival and predation of a prey fish in Lake Ontario, 48 bloater Coregonus hoyi were tagged with acoustic telemetry predation tags and were tracked on an array o...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Long‐term retention of acoustic telemetry transmitters in temperate predators revealed by predation tags implanted in wild prey fishNARA Subscribed
Bloater Coregonus hoyi ( n = 48) were implanted with V9DT‐2x predation transmitters and monitored on 105 acoustic receivers in eastern Lake Ontario for >6 months. Twenty‐three predation events were observed, with predator retention of tags ranging from ≤1 to ≥194 days and 30% of retentions lasting >150 days. Long tag retention times raise concerns for acoustic telemetry analysis and the health of piscivorous predators retainin...
In this study, we investigated the effects of acoustic tag implantation on standard and routine metabolic rate (SMR and RMR, estimated via oxygen consumption), critical swimming speed ( U crit ), survival and growth in juveniles of rainbow trout Oncorhynchus mykiss and lake trout Salvelinus namaycush . Tag burdens ranged from 1.8% to 7.5% across the two species. Growth rates in acoustic‐tagged fish were equal to or higher than...
Novel molecular approach demonstrates that turbid river plumes reduce predation mortality on larval fishNARA Subscribed
Turbidity associated with river plumes is known to affect the search ability of visual predators and thus can drive ‘top‐down’ impacts on prey populations in complex ecosystems; however, traditional quantification of predator–prey relationships (i.e. stomach content analysis) often fails with larval fish due to rapid digestion rates. Herein, we use novel molecular genetic methods to quantify larval yellow perch ( YP ) in preda...
