title: Distribution of spectacled eiders in Russia and Alaska 1993-1996 (data from Petersen et al. 1999)

description: Petersen MR, Larned WW, Douglas DC (1999) At-sea distribution of spectacled eiders: a 120-year-old mystery resolved. The Auk 116(4): 1009–1020. doi:10.2307/4089681
description: The at-sea distribution of the threatened Spectacled Eider (Somateria fischeri) has remained largely undocumented. We identified migration corridors, staging and molting areas, and wintering areas of adult Spectacled Eiders using implanted satellite transmitters in birds from each of the three extant breeding grounds (North Slope and Yukon-Kuskokwim Delta in Alaska and arctic Russia). Based on transmitter locations, we conducted aerial surveys to provide visual confirmation of eider flocks and to estimate numbers of birds. We identified two principal molting and staging areas off coastal Alaska (Ledyard Bay and eastern Norton Sound) and two off coastal Russia (Mechigmenskiy Bay on the eastern Chukotka Peninsula, and the area between the Indigirka and Kolyma deltas in the Republic of Sakha). We estimated that &gt;10,000 birds molt and stage in monospecific flocks at Mechigmenskiy and Ledyard bays, and several thousand molt and stage in eastern Norton Sound. We further identified eastern Norton Sound as the principal molting and staging area for females nesting on the Yukon-Kuskokwim Delta, and Ledyard Bay and Mechigmenskiy Bay as the principal molting and staging areas for females nesting on the North Slope. Males marked at all three breeding grounds molt and stage in Mechigmenskiy Bay, Ledyard Bay, and the Indigirka-Kolyma delta region. Males from the Yukon-Kuskokwim Delta molt and stage mainly at Mechigmenskiy Bay. Equal numbers of males from the North Slope molt and stage at all three areas, and most males from arctic Russia molt and stage at the Indigirka-Kolyma delta region. Postbreeding migration corridors were offshore in the Bering, Chukchi, and Beaufort seas. In winter, eiders were in the Bering Sea south of St. Lawrence Island. Our estimates from surveys in late winter and early spring suggest that at least 333,000 birds winter in single-species flocks in the pack ice in the Bering Sea.

title: HELiX Uncrewed Aircraft System data from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) campaign, multispectral imagery data

description: Data are available for download at: https://arcticdata.io/data/10.18739/A2RV0D21Z/ This dataset consists of multispectral imagery data products produced from HELiX uncrewed aircraft system (UAS) flights that were conducted over or near sea ice during the MOSAiC expedition. These data were produced from raw multispectral imagery acquired by the Helix’s gimbal-mounted RedEdge-MX camera. Additional data from the Helix UAS’ other sensors, which consist of hemispheric irradiance measurements from two Kipp and Zonen pyranometers and thermodynamic parameters from two Vaisala RSS421 sensors can be found in Radiance Calmer, Gijs de Boer, Jonathan Hamilton, Dale Lawrence, Steve Borenstein, et al. 2021.

HELiX Uncrewed Aircraft System data from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) Campaign. Arctic Data Center. doi:10.18739/A2GH9BB0Q (B1 data). Three main flight types were conducted with the Helix: a grid pattern, hover, and profile. Pix4D was used to produce five (one for each channel of the camera) orthomosaics, reflectance maps, and colorized index maps for all flight types. A video of the images taken during the flight, including an image scale, UTC time, and altitude overlay was produced for each profile flight.

title: Alberta Bog Net Nitrogen Mineralization, 2013-2015

description: Alberta bogs are subject to periodic wildfire. Although these bogs have persisted under low atmospheric nitrogen deposition (less than 2 kg N/ha/yr), nitrogen deposition in northern Alberta is increasing due to ongoing oil sands development. This study examined how time since fire and experimental N deposition affects nitrogen mineralization in near-surface bog peat. Net nitrogen mineralization (ammonification, nitrification, dissolved organic N production) was quantified using the buried bag technique in 5 Alberta bogs differing in time since fire. At each site, 24 2.4 _ 4.8 m plots were established, with 6 replicate plots receiving one of four N addition treatments: controls (receiving no water or N), H2O controls (receiving water, but no N; 0 kg N ha-1 yr-1), and 10 and 20 kg N ha-1 yr-1, applied as NH4NO3 dissolved in 15 L of H2O and applied via backpack sprayer eight times during each summer field season. We established plots and began N additions in 2011 at the Utikuma Bog site and in 2013 for the other four sites.

title: Post-fire SOC and delta-13C at different types of microsite at a grassland-shrubland ecotone

description: Woody plant encroachment of grassland ecosystems is a geographically extensive phenomenon that can lead to rapid land degradation and significantly alter global biogeochemical cycles, and this ecosystem change has been particularly well documented in the desert grassland of the southwestern United States. Fires are known to decrease vegetation cover and increase soil erodibility, and the shifts in wildfire regimes are currently occurring in Chihuahuan Desert. It is generally recognized that the invasion of woody vegetation into grasslands and savannas will increase the carbon stored in arid ecosystems. However, carbon storage may be complicated by disturbance such as wildfire, which alters the distribution and amount of C pools in the drylands. The relative distribution of each vegetation type to the soil C pool and its variability after fires are not well-understood in this ecosystem. This research will investigate the variations of SOC and its vegetation source partition at microsite scale in the woody shrub encroached grassland after the occurrence of fire, which will provide further information on wildfireâ€™s influence on soil C pool dynamics in arid and semiarid lands. The post-fire changes of the spatial pattern of SOC and vegetation contributions in the shrub encroached grassland will be analyzed using a geostatistical method outlined in Guan et al. (2018). Overall, understanding the post-fire redistribution and sources of SOC may provide insights on the important role played by fire, aeolian processes and vegetation in the dynamics of desert grassland ecosystems.

description: Moritz M, Garcia V, Buffington A, Ahmadou M (2019) Pastoralist refugee crisis tests the resilience of open property regime in the Logone Floodplain, Cameroon. Land Use Policy 86: 31–42. doi:10.1016/j.landusepol.2019.04.028
description: Previous studies have shown that the open property regime of mobile pastoralists in the Logone Floodplain, Cameroon works as a complex adaptive system in which individual movement decisions result in an ideal free distribution of grazing pressure over common-pool grazing resources. Recently, the humanitarian crisis in the Chad Basin caused by Boko Haram has resulted in the arrival of thousands of pastoralist refugees from Northeastern Nigeria in the Far North Region of Cameroon. In this paper, we examine the impact of pastoralist refugees on the resilience of the open property regime. First, we describe the migratory flight of pastoralists. Second, we examine whether and how the pastoralist refugee crisis affected the open property regime, in par- ticular the distribution of pastoralists over grazing resources. Data were collected in a longitudinal and inter- disciplinary study that integrated spatial and ethnographic approaches to describe and explain the distribution of pastoralists in the Logone Floodplain from 2008 to 2016. The results show that the number of pastoralist re- fugees from Nigeria exceeds 1000 households with an estimated 100,000 cattle. However, despite the large number of pastoralist refugees, we continue to find evidence of an ideal free distribution of pastoralists over grazing resources in the Logone Floodplain. Moreover, we found that pastoralists, while frustrated by the in- creasing grazing pressure, remained committed to the ethos of open access. The study offers evidence of the resilience of the open property regime and we discuss the reasons for the resilience of this complex adaptive system using the concept of panarchy.

title: SBC LTER: Reference: Sea-aurface water temperature, Santa Barbara Harbor, Santa Barbara, CA, USA, 1955 to present, ongoing

description: The SBC-LTER has access to data on seawater temperature collected at Santa Barbara Harbor, Santa Barbara, CA, USA through the Scripps Insitution of Oceanography Manual Shore Stations program. Each morning, Santa Barbara Harbor Patrol personnel record the surface water temperature from their boat dock at the west end of the harbor. The harbor enjoys good tidal circulation and the sample is taken before the sun can exert a warming effect, so these temperatures are believed to be representative of the coastal waters. Data have been collected daily since 1955. The SIO Manual Shore Stations program provides data and information about this shore station. For further information, please visit the SIO Manual Shore Stations website at http://shorestation.ucsd.edu. Please note: manual shore station data is updated periodically, not continuously.

title: SBC LTER: Kelp Removal Experiment: Daily photon irradiance at the surface and seafloor

description: These data are total daily photon irradiance in mol quanta m-2 d-1 at the sea surface and reaching the sea floor at SBC LTER kelp removal experiment sites. Sensors record instantaneous irradiance at one minute intervals, and data are averaged hourly and integrated over a 24 hour period. Sensors are mounted on the sea floor at one kelp-control and two kelp-removal plots at four sites (Arroyo Quemado, Carpinteria, Naples Reef and Mohawk Reef). At Mohawk Reef and Arroyo Quemado, sensors are also mounted above the sea surface on a spar buoy. No surface sensor was deployed at Naples Reef, and at Carpinteria, a surface sensor was deployed only for the period January 2008 to April 2010. Data are collected with MkV/L Light Intensity Recorders manufactured by Alec Electronics Corporation. The kelp removal experiment was initiated in 2008 at selected reef sites along the mainland coast of the Santa Barbara Channel. The following three giant kelp manipulations are maintained in sampling plots at each site: Control:Macrocystis pyriferais left intact in a 2000 m2plot. Annual removal:Macrocystis pyriferais removed from an adjacent 2000 m2plot once each winter and allowed to re-colonize over the course of the year. Continuous removal:Macrocystis pyriferais removed from a 200 m2area within the 2000 m2plot on each sampling date.

title: Study "Bulgaria Sofia - Long term study on migratory movement of Alpine swifts (Apus melba)"

description: Meier CM, Karaardıç H, Aymí R, Peev SG, Witvliet W, Liechti F. 2020. Population-specific adjustment of the annual cycle in a super-swift trans-Saharan migrant. J Avian Biol. 51(11):e02515. doi:10.1111/jav.02515
description: For migratory birds optimal timing of the onset of reproduction is vital, especially when suitable conditions for reproduction occur only for a short while during the year. With increasing latitude the suitable period becomes shorter and we expect the organization of annual cycle to be more synchronized to the local conditions across individuals of same population. This should result in low variation of arrival and departure date in breeding sites at higher latitudes. We quantify the temporal and geographical variation in pre- and post-breeding migration between individuals from four different populations of alpine swifts (Tachymarptis melba) along a latitudinal gradient. We tracked 215 individuals in three years with geolocators. The two western and two eastern populations showed separate migratory flyways and places of residence in Africa. Length of stay at the breeding sites was negatively correlated with latitude and differed by more than a month between populations. Duration of migration was similarly short in all populations (median 6.2 days in autumn and 8.7 days in spring). However, variation in timing of migration was unrelated to latitude and individuals everywhere arrived in the same asynchrony at the breeding site.
