Ecological “big data” Human activities are rapidly altering the natural world. Nowhere is this more evident, perhaps, than in Arctic, yet region remains one of most remote and difficult to study. Researchers have increasingly relied on animal tracking data these regions understand individual species' responses, but if we want larger-scale change, need integrate our understanding across species. Davidson et al. introduce an open-source archive that currently hosts 15 million location points...
Abstract Conservation status and management priorities are often informed by population trends. Trend estimates can be derived from surveys or models, but both methods associated with sources of uncertainty. Many Arctic-breeding shorebirds thought to declining based on migration and/or overwintering surveys, data lacking estimate the trends some shorebird species. In addition, for most species, little is known about stage(s) at which bottlenecks occur, such as breeding vs. nonbreeding...
While increases in overall temperatures are widely reported the Arctic, large inter-annual variation spring weather, with extreme early and late conditions, is also occurring. Using data collected from three sites Arctic Alaska, we explored how shorebird breeding density, nest initiation, synchrony, survival, phenological mismatch varied between two exceptionally (2015 2016) (2017 2018) springs. We assessed these differences context of long-term each site whether species exhibited...
Abstract Global climate change has altered the timing of seasonal events (i.e., phenology) for a diverse range biota. Within and among species, however, degree to which alterations in phenology match variability differ substantially. To better understand factors driving these differences, we evaluated variation nesting eight Arctic‐breeding shorebird species at 18 sites over 23‐year period. We used Normalized Difference Vegetation Index as proxy determine start spring (SOS) growing season...
Determining the dynamics of where and when individuals occur is necessary to understand population declines identify critical areas for populations conservation concern. However, there are few examples a spatially temporally explicit model has been used evaluate migratory bird across its entire annual cycle. We geolocator-derived migration tracks 84 Dunlin ( Calidris alpina ) on East Asian-Australasian Flyway (EAAF) construct network describing subspecies-specific patterns in space time....
Abstract Oil and gas exploration development is expanding across the Arctic Coastal Plain (ACP) of Alaska, USA. To examine effects industrial on greater white‐fronted geese ( Anser albifrons ), we monitored nests nesting behavior within a 4‐km 2 study area 4 km gravel roads pads during pre‐development, construction, operation activities at new oil in National Petroleum Reserve‐Alaska 2013−2019. We examined distribution, incubation constancy, nest survival relation to distance or pads, year...
The Sabine's Gull (Xema sabini) is a pelagic, Arctic-breeding species with circumpolar breeding distribution. Little known about migration routes for northern Alaska-breeding Gulls. We tagged Gulls on their Alaska grounds to identify and wintering areas compare geolocators GPS pinpoint tags use small-bodied gulls. Twelve were deployed in 2011 (Colville River delta) of which four recovered, five 2021 (Qupaluk). Although the provided more accurate locations allowing finer-scale habitat...
Long-distance migrants are under strong selection to arrive on their breeding grounds at a time that maximizes fitness. Many arctic birds start nesting shortly after snow recedes from sites and timing of snowmelt can vary substantially over the range widespread species. We tested hypothesis migration schedules individuals co-occurring same non-breeding areas adapted average local environmental conditions encountered specific distant Arctic locations. predicted site availability (measured...
Cameras are important tools used to determine nest fate, identify predators and evaluate behaviour; however, they may impact the parameters measure, thereby biasing results. We evaluated of cameras ˜ 10 m from on shorebird survival at Canning River Delta, Alaska, 2017–2018 ( n control = 122, camera 109) using a much larger sample size than in previous studies conducted Arctic random assignments discovery. found no effect presence daily (model‐averaged rate (DSR) 85% confidence interval (CI);...
The Arctic Coastal Plain is one of the most important avian breeding grounds in world; however, many species are decline. Arctic‐breeding birds contend with short seasons, harsh climatic conditions, and now, rapidly changing, variable, unpredictable environmental conditions caused by climate change. Additionally, those industrial areas may be impacted human activities. It difficult to separate impacts development change; long‐term datasets can help show patterns over time. We evaluated...
Abstract Addressing urgent conservation issues, like the drastic declines of North American migratory birds, requires creative, evidence-based, efficient, and collaborative approaches. Over 50% monitored shorebird populations have lost over their abundance since 1980. To address these declines, we developed a partnership scientists practitioners called Shorebird Science Conservation Collective (hereinafter “the Collective”). Here, present this successful case study as an example for others...
Abstract Kubelka et al. (Science, 9 November 2018, p. 680-683) claim that climate change has disrupted patterns of nest predation in shorebirds. They report rates have increased since the 1950s, especially Arctic. We describe methodological problems with their analyses and argue there is no solid statistical support for claims.
The Wilson's Plover (Charadrius wilsonia) occurs along the Atlantic and Pacific coasts from United States to Brazil, occasionally in Chile. It is known breed States, Mexico, Belize, El Salvador, Costa Rica, Colombia, Jamaica, West Indies, Peru. Outside we know little about its reproduction nesting site habitats. On 12 May 2019, observed a female at nest with 3 eggs separate pair of adults 2 chicks around ponds Mayasal shrimp farm Jutiapa, Guatemala. These reports are first records...
