This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

The existence of a dark morph in adult Long-tailed Jaeger (Stercorarius longicaudus) is still unclear and debated. For this species, dark plumages occur in juveniles and immatures, but no dark morph adults have yet been unequivocally confirmed. Ambiguous reports of presumed dark morph adults and lack of information on molt progression of immatures...
Scientists, policy makers, and journalists are three key, interconnected players involved in prioritizing and implementing solutions to mitigate the consequences of anthropogenic pressures on the environment. The way in which information is framed and expertise is communicated by the media is crucial for political decisions and for the integrated m...
Climate change can affect the distribution, abundance, and phenology of organisms globally. Variations in the timing of passage during autumn and spring migration can have consequences at individual and population levels. We assessed whether global climatic indexes and increasing air temperature over a 28 yr period were concurrent with shifts in th...
Since the mid-20th century, climate change and biodiversity loss have been identified as major consequences of anthropological pressures and both have already transgressed safe limits. Given their significance for human health and well-being and their large-scale effects, international cooperation is crucial to address these issues. Intergovernment...
The historical decline of the peregrine falcon (Falco peregrinus) in North America during the 20th century was mainly attributed to reproductive failure due to the accumulation of persistent organochloride pollutants. As a direct result to this finding, the Arctic Raptor Project was established in 1982, and its goal was to monitor the breeding succ...

... Effective communication and diffusion strategies are needed to raise awareness and commitment to achieving environmental sustainability [34,14]. Thus, finding effective means to engage human behavior change for conservation issues is one of the top priorities for modern conservation science [32,5]. ...
... As long-lived top predators holding large home ranges and preying on a wide variety of vertebrates and invertebrates, raptors are influenced by the effects of environmental change on lower trophic levels (Meserve et al. 2003, Schmidt et al. 2018) and can serve as biotic multipliers of climate change (Urban et al. 2017). Raptors have been the focus of multiple long-running studies on 1 The editorial processing and review of this paper were handled by Associate Editor James F. Dwyer. 2 Corresponding author: cheryldykstra@gmail.com migration (e.g., Sullivan et al. 2016, Therrien et al. 2017 and breeding rate (e.g., Fasce et al. 2011, Jiménez-Franco et al. 2020, Maciorowski et al. 2021, which provide valuable long-term data sets that allow assessment of change (e.g., Lee et al. 2020). Additionally, raptors with specialized habitat or feeding strategies are likely to be disproportionally affected by climate change because of their narrow ecological niche and lack of plasticity , Hof et al. 2012. ...
... Nesting data were gathered by different sources and search effort was not recorded in the database. Nest locations were therefore spatially clumped, with a disproportionately high density of nesting sites in some well-surveyed areas of Nunavut (e.g., the long-term monitoring program at Rankin Inlet, Nunavut; Jaffré et al. 2015). There are several ways to account for biased sampling effort including down-weighting records in areas that received more survey effort, adding more data by surveying areas that are under-represented, or sampling background or pseudo-absence data only from areas that were likely surveyed (Poole 2011;Peck et al. 2012). ...
