Test anxiety (TA) can lower student GPA and increase dropout rates in populations of university students. Despite numerous treatment options, many students still suffer from TA. The stigma attached to this type the incidence perceptions TA were quantified through surveys distributed 1,099 at a Canadian university. Results study indicated that 38.5% (30.0 % males, 46.3 females) suffered self-reported some point over course their career. prevalence varied by faculty, with highest among those...

Molecular scatology and next-generation sequencing identified previously unknown linkages among ecosystems in the diet of Semipalmated Sandpipers (Calidris pusilla) Bay Fundy, Canada. During their annual migratory stopover, birds consumed a wider range prey items than reported, which suggests that they are not selecting for amphipod Corophium volutator acting as generalist foragers. Our analysis several novel items—arachnids, crabs, bivalves, terrestrial freshwater insect species,...

The process of peer-review in academia has attracted criticism surrounding issues bias, fairness, and professionalism; however, frequency occurrence such comments is unknown.We evaluated 1491 sets reviewer from the fields "Ecology Evolution" "Behavioural Medicine," which 920 were retrieved online review repository Publons 571 obtained six early career investigators. Comment coded for "unprofessional comments" "incomplete, inaccurate or unsubstantiated critiques" using an a-prior rubric based...

The European green crab (Carcinus maenas), native to northwestern Europe and Africa, is among the top 100 most damaging invasive species globally. In some regions, including Atlantic coast of North America, C. maenas has caused long-term degradation eelgrass habitats bivalve, crab, finfish populations, while other areas are near beginning invasion cycle. Owing high persistence reproductive potential local regional mitigation efforts no longer strive for extirpation instead focus on...

Within the burgeoning field of restoration ecology, defining concept reclamation relative to rehabilitation and ecological is important enhance comparability between studies, as well enable clear communication project specific methods goals. The Society for Ecological Restoration's international standards (SER Standards), second edition, defines “the process making severely degraded land fit cultivation or a state suitable some human use.” However, we posit that this definition, its...

Abstract Diversity estimates play a key role in ecological assessments. Species richness and abundance are commonly used to generate complex diversity indices that dependent on the quality of these estimates. As such, there is long‐standing interest development monitoring techniques, their ability adequately assess species diversity, implications for generated indices. To determine substratum community assessment methods capture we evaluated four methods: photo quadrat, point intercept,...

Top-down, bottom-up, middle-out and abiotic factors are usually viewed as main forces structuring biological communities, although assessment of their relative importance, in a single study, is rarely done. We quantified, using multivariate methods, associations between biotic (top-down, bottom-up middle-out) variables infaunal population/community variation on intertidal mudflats the Bay Fundy, Canada, over two years. Our analysis indicated that spatial structural like site plot accounted...

We examined biotic and abiotic variables on the expansive intertidal mudflats of upper Bay Fundy, Canada, at 8 geographically separate sites over 2 years (2009–2011). Invertebrate density, surface density primary producers (mainly diatoms, measured as chlorophyll-a concentration), shorebird- fish-foraging activity, sediment properties varied considerably through time space. Dissimilarity in invertebrate community between consecutive sampling rounds was lower during peaks richness...

Abstract Aquatic ecosystems have been managed for millennia. Indigenous communities in North America pioneered numerous marine resource management strategies to ensure food security and support thriving economies, which active throughout the Northwest Coast of over 14 000 years. Developed increase shellfish productivity, clam gardens The diverse infaunal within these can act as indicators habitat alterations provide an opportunity study ecological community responses seascapes shaped by...

The bioaccumulation of Potentially Toxic Elements (PTEs) by benthic invertebrates in estuarine sediments is poorly understood. We sampled and analysed PTEs from five sites the Skeena Estuary (British Columbia, Canada), including adjacent to an abandoned cannery a decommissioned papermill. Our aim was elucidate baseline levels PTE concentrations at that may be recovering disturbance associated with prior industrial development identify organisms could used biomonitor impact future...

As we enter the United Nations Decade of Ecosystem Restoration, need to engage in restoration activities has never been greater. Included within this is a requirement for clear communication between researchers, practitioners, policymakers, stakeholders, and community members. To facilitate discussion assessment restorative activities, propose two decision trees differentiate key terms (Reclamation, Rehabilitation, Ecological Rewilding, Landscape Intra-Ecosystem Reference Condition...

Dispersal, the movement of an individual away from its natal or breeding ground, has been studied extensively in birds and mammals to understand costs benefits behavior. Whether not invertebrates disperse response such attributes as habitat quality density conspecifics remains uncertain, due part difficulties marking recapturing invertebrates. In upper Bay Fundy, Canada, intertidal amphipod Corophium volutator swims at night around new full moon. Furthermore, this species is regionally...

Efficiently evaluating industrial activities plays an essential role in determining the extent to which human–ecosystem interactions may lead species loss, disrupted community dynamics, and degraded ecosystems. Intertidal habitats offer a unique opportunity this regard, as they are rich ecosystems that exhibit rapid turnover pronounced responses ecological disturbances. In attempt use these dynamic communities identify impact storage of harvested logs is having on Kitimat River estuary,...

Productivity of temperate streams and lakes is often limited by availability key nutrients, nutrient‐poor habitats are termed oligotrophic. Oligotrophic occur naturally, but a product human activities (cultural oligotrophication), such as the creation dams. Cultural oligotrophication has resulted in declining productivity lakes, condition that can manifest itself collapsing salmonid fish stocks. To counteract lost part restoration or compensation measures, managers add nutrient via...
