To promote inclusivity, relevance and actionability of environmental research, scholars are engaging with rightsholders and stakeholders (Indigenous groups, governments and individuals) to co‐produce research. These transdisciplinary approaches represent diverse forms of ‘engaged’ research (e.g. community‐engaged research, braiding Indigenous science and knowledge and Western science‐based knowledge, workshops with decision‐makers). Acknowledging the diversity in aims and approaches to transdisciplinary research, this study surveyed a broad group of Canadian environmental researchers ( n = 61) to understand: their motivations and objectives for engagement, how they manage engagement processes, how they assess the success of engagement, and the insights they would highlight for others interested in engaging in various forms of knowledge co‐production. We used qualitative methods to identify key themes and supported our findings with quantitative measures (i.e. frequency and proportion of participants who gave particular responses). We found that the motivations, geographic context, and practical experiences of researchers were diverse. A strong theme was the value of reciprocity. Recurring advice included the importance of understanding the research context and actor landscape prior to contacting collaborators, conducting iterative discussions with research collaborators to scope and plan the project, and being sure to locate the individuals or entities that may hold key knowledge or the ability to grant permissions. We note the importance of paying close attention to power asymmetries during the research process. Dialogue with stakeholders, rightsholders and communities is time‐consuming. Devoting adequate time for building and maintaining relationships to achieve a requisite level of trust is essential, but can be challenging for all parties. We conclude that there is no substitute for one‐on‐one mentoring for learning and understanding how to lead ethical and effective knowledge co‐production processes. Researchers setting out to collaborate with stakeholders, rightsholders, and communities must learn the norms, rules, and social dynamics of a given context and culture—and they should seek out experienced counsel for preparation and coaching before engaging in collaborations.

In response to recent alignment of political leadership in Canada and the United States with respect to global nature conservation imperatives, a nascent and intentional dialogue has emerged on transboundary connectivity conservation between the two countries. In February and April 2021, two meetings were remotely convened, bringing together more than 160 participants from key government agencies, non-governmental organizations and Indigenous Nations engaged in conservation in both countries. Participants generated 25 concrete ideas for key next steps and 11 broad strategies that, when considered together, comprise 11 priority policy directions. Among these, four core policy imperatives include (1) prioritizing opportunities to coordinate within and among Indigenous communities, (2) creating formalized memorandums of understanding (MOUs) and funding commitments between the US and Canada, (3) mainstreaming connectivity into sectors and society, and (4) initiating systemwide changes in governance and economic structures. Together, these policy directions represent important strategies at this crucial inflection point. Only rarely are nations given historic policy alignment opportunities to redefine and reinvigorate their common conservation goals. Particularly salient is the drive to embrace transboundary connectivity conservation as a nature-based solution to climate change adaptation. We see this dialogue as a beginning in securing the peace that defines two countries and numerous Indigenous Nations that are inextricably linked by ecology and culture.

Pharmaceuticals and personal care products (PPCPs) include over-the-counter and prescription drugs, veterinary drugs, fragrances, and cosmetics. PPCPs have been detected in aquatic environments at low concentrations and are emerging as contaminants of concern. PPCPs are primarily released into aquatic environments via untreated sewage, wastewater treatment plants, landfill leachate and can affect aquatic life through persistence, bioaccumulation, and toxicity. However, there are limited reviews of lethal and sublethal effects of PPCP exposures on aquatic organisms. To understand PPCP toxicity on aquatic organisms, a literature review was conducted that identified aquatic organisms known to be affected by PPCPs; concentrations of PPCPs reported as producing sublethal and lethal effects in aquatic organisms; and research gaps on PPCP aquatic toxicity. Twelve PPCPs were selected from three seminal studies for review, including bisphenol A, carbamazepine, erythromycin, fluoxetine, linear alkylbenzene sulfonate, metoprolol, naproxen, nonylphenol, ofloxacin, sertraline, sulfamethoxazole, and triclosan. Many aquatic species were affected by PPCPs at sublethal and lethal exposures, including sublethal effects at environmentally relevant concentrations. Because lethal effects were seldom observed at environmentally relevant concentrations, many studies considered PPCPs non-toxic. Few studies have compared effects of PPCPs on the same organisms for identical exposure parameters (time and concentration), resulting in wide variation in reported toxicity levels with limited consensus in the academic literature. Consensus in lethal concentrations was reported for Daphnia magna with 48 h exposure for bisphenol A and triclosan and Vibrio fischeri with 15 min exposure to carbamazepine. Environmentally relevant sublethal concentrations were higher than water quality guidelines developed for Canada and predicted no-effect concentrations derived globally. Species sensitivity distributions for some PPCPs show that aquatic species are affected lethally at environmentally relevant concentrations. More studies on indirect and long-term ecological effects along with testing chronic toxicity of PPCPs at environmentally relevant concentrations are recommended. These will help guide future research to determine extent and magnitude of PPCP concentrations in aquatic environments and help inform management decisions to reduce sources of PPCPs into the environment. Future management requires effective monitoring strategies regarding use, disposal, occurrence, and impacts at different life cycle stages of PPCPs in the environment.

The Active River Area (ARA) is a spatial approach for identifying the extent of functional riparian area. Given known limitations in terms of input elevation data quality and methodology, ARA studies to date have not achieved effective computer-based ARA-component delineation, limiting the efficacy of the ARA framework in terms of informing riparian conservation and management. To achieve framework refinement and determine the optimal input elevation data for future ARA studies, this study tested a novel Digital Elevation Model (DEM) smoothing algorithm and assessed ARA outputs derived from a range of DEMs for accuracy and efficiency. It was found that the tested DEM smoothing algorithm allows the ARA framework to take advantage of high-resolution LiDAR DEM and considerably improves the accuracy of high-resolution LiDAR DEM derived ARA results; smoothed LiDAR DEM in 5-meter spatial resolution best balanced ARA accuracy and data processing efficiency and is ultimately recommended for future ARA delineations across large regions.

Due to ubiquitous distribution of taxa, relatively low-cost and efficient sampling procedure, and known responses to environmental gradients, macroinvertebrate indicators are often a central component of biological monitoring of freshwater resources. This study examined establishing a baseline reference of benthic macroinvertebrate indicators in a biomonitoring approach as a means for monitoring the freshwater ponds of Sable Island National Park Reserve (SINPR), Canada. We compared water quality parameters monitored from 2015 to 2019 to a biomonitoring approach deployed in May, June, and August of 2019. A total of 27 taxa were recorded from the 30,226 specimens collected, with highest abundances of Corixidae, Amphipoda, Oligochaeta, and chironomid species Polypedilum bicrenatum. We found significant variability of community structure between different months of sampling (p = 0.001) and between ponds (p < 0.0001). A high correlation was found between dissolved organic carbon, sulfate, and the diversity of macroinvertebrate indicators, while conductivity, ammonia, and calcium were found to be correlated with species richness. While we found that water chemistry parameters exhibited spatial and temporal differences, the diversity of macroinvertebrate indicators is likely to be a more resilient metric for comparison between ponds. Further, our findings demonstrate that biomonitoring can be effective in systems with a low number of small, shallow, freshwater pond ecosystems. As our study deployed a high-resolution identification of biological indicators, we were able to establish a baseline reference for future monitoring as well as identify specific associations between pond water quality and biological assemblages that can be used as a context for the management of SINPR’s freshwater resources. Continued monitoring of these ecosystems in future years will help to understand long-term environmental changes on the island.

Precipitous declines in biodiversity threaten planetary boundaries, requiring transformative changes to conservation. Colonial systems have decimated species and ecosystems and dispossessed Indigenous Peoples of their rights, territories, and livelihoods. Despite these challenges, Indigenous-governed lands retain a large proportion of biodiversity-rich landscapes. Indigenous Peoples have stewarded the land in ways that support people and nature in respectful relationship. Biodiversity conservation and resurgence of Indigenous autonomies are mutually compatible aims. To work towards these aims requires significant transformation in conservation and re-Indigenization. Key to both are systems that value people and nature in all their diversity and relationships. This paper introduces Indigenous principles for re-Indigenizing conservation: (i) embracing Indigenous worldviews of ecologies and M’sɨt No’kmaq, (ii) learning from Indigenous languages of the land, (iii) Natural laws and Netukulimk, (iv) correct relationships, (v) total reflection and truth, (vi) Etuaptmumk—“two-eyed seeing,” and “strong like two people”, and (vii) “story-telling/story-listening”. Although the principles derive primarily from a Mi’kmaw worldview, many are common to diverse Indigenous ways of knowing. Achieving the massive effort required for biodiversity conservation in Canada will entail transformations in worldviews and ways of thinking and bold, proactive actions, not solely as means but as ongoing imperatives.
