Little is known about the current state of freshwater biodiversity in Canada, one countries with greatest amount surface waters world. To address this knowledge gap, we compiled a list all available assessments conservation status for species (over 3000 taxa) and further evaluated overall six distinct taxonomic groups, focusing on organisms reliant fresh (i.e., aquatic plants, invertebrates (with focus mussels), fishes, herpetofauna (reptiles amphibians), birds, mammals). Overall, 11.7%...
In response to the coronavirus (COVID-19) pandemic, there has been an increased need for personal and environmental decontamination aid in curbing transmission of SARS-CoV-2 virus. Products used this purpose include sanitizers hands disinfectants surfaces. The active chemical ingredients these products, termed antimicrobials, can enter waste streams after application may be emerging as more prominent contaminants. Even prior COVID-19, was recognized examine their implications aquatic biota,...
Abstract Aim Understanding the magnitude and drivers of freshwater diversity over last 150 years provides essential insights for developing scenarios future change. Here, we quantify identify spatial temporal beta in diatom assemblages between historical modern times. Location United States America. Major Taxa Studied Diatoms. Tim Period pre‐AD 1850 c. 2007. Methods Using sedimentary genus‐level data from 169 lakes species‐level 52 lakes, computed across all within ecoregions 2007 time...
Abstract Freshwater biodiversity loss is one of the greatest environmental threats in our changing world. Although declines have been reported extensively literature, much less attention has devoted to solving freshwater crisis relative other ecosystems. The recently proposed Emergency Recovery Plan for Biodiversity (Tickner et al., 2020, BioScience, 70 (4), 330–342) outlines an ambitious but necessary set overarching actions that can help “bend curve” declines. This plan timely given...
Biodiversity surveys have long depended on traditional methods of taxonomy to inform sampling protocols and determine when a representative sample given species pool interest has been obtained. Questions remain as how design appropriate efforts accurately estimate total biodiversity. Here we consider the biodiversity freshwater ostracods (crustacean class Ostracoda) from region Churchill, Manitoba, Canada. Through an analysis observed richness complementarity, accumulation curves,...
Summary Threats to biodiversity are fostering new collaboration between aquatic ecologists and palaeolimnologists, who have traditionally asked ecological questions on different time scales. While the differences surface sediment water column or snapshot sampling well understood, less so consequences of comparing predominant drivers assemblages resulting from these two types sampling. Using diatom data 2007 USEPA National Lakes Assessment (NLA) program (468 lakes), we compared main...
The lakes surrounding the iron ore mining region of Schefferville, Quebec, Canada, sit within a landscape historical disturbances, two which have been relatively well documented over time: metal contamination and nutrient loading. Based on analysis sediment cores, we used cladoceran zooplankton subfossil assemblages from located in Schefferville to track both alpha beta diversity last 100+ years. We showed that high concentrations were correlated with decreased diversity, site experienced...
Effective management of freshwater fish habitat is essential to supporting healthy aquatic ecosystems and sustainable fisheries. In Canada, recent changes the Fisheries Act enhanced protection habitat, but application those provisions relies on sound scientific evidence. We employed collaborative research prioritization methods identify questions that, if addressed, would significantly advance in Canada. This list was generated by a diverse group experts, including substantial contributions...
Inherent differences between naturally-formed lakes and human-made reservoirs may play an important role in shaping zooplankton community structure. For example, because many are created by impounding managing lotic systems for specific human purposes, communities be affected factors that unique to reservoirs, such as shorter water residence times a reservoir's management regime, compared natural lakes. However, the environmental structure vs. vary at continental scale remain largely...
International efforts to implement the Paris Agreement call for unprecedented levels of collaboration address one society's most pressing crises. In this study we take position that climate action work is very public work, in decarbonization requires significant effort learn together ways change commitments enact environmental stewardship. To better understand challenge, examined citizen science as a space where also knowledge co-creation. Pre–post experience surveys and interviews with...
Community science involves the co-creation of scientific pursuits, learning, and outcomes is presented as a transformative practice for community engagement environmental governance. Emphasizing critical reflection, this study adopts Mezirow’s conception learning to theorize capacity science. Findings from interviews with participants in program reveal although instances acknowledging attitudes beliefs without challenging personal assumptions were more common. Program elements most likely...
The reduction of environmental legislation and regulation has become a common practice for governments looking to reduce government overhead while boosting private sector investment. Following this trend, in 2012 Canada enacted major legislative changes its policies. Canadian Environmental Assessment Act (CEAA) was overhauled, related Acts, including the (federal) Navigable Waters Protection (NWPA), saw their regulatory processes reduced. There is need aquatic scientists better understand...
