Shelf life of batteries largely … In a world undergoing massive declines in the distribution and abundance of many wildlife species, documenting basic ecological characteristics is often needed to be able to understand and potentially mitigate current and future pressures. In 2015 the species was classified as near threatened (NT) in the Norwegian Red List of Species (Henriksen and Hilmo, 2015). (2015). October 26, 2020 For each individual, we had between zero and 16 relocations. Mail. That is a costly mistake. The IUCN Red List of Threatened Species 2016 [Online]. The radio transmitters had an expected battery lifetime of 24 months (RI‐2BM) or 30 months (RI‐2DM) and included a mortality circuit that was activated if a bird had been immobile for 12 hr. Based on the pooled sample, overall probability to survive from February 1st and through July was estimated at 0.45 (SE: 0.07) (Figure 2), with natural survival (i.e., disregarding birds that were shot by hunters during the harvest season) estimated at 0.55 (SE: 0.07). SALE. It is however important to note that part of the winter mortality reported in our case study was caused by harvest, which is previously shown to be at least partially additive to other mortality sources in willow ptarmigan (Sandercock et al., 2011). Glob. Climate Events Synchronize the Dynamics of a Resident Vertebrate Community in the High Arctic. A total of 6 birds moved longer than 50 km, of which four were males and two were females. 42, 453–459. Brand: GT Power.

Compared to other grouse species, the rock ptarmigan are among the least studied species in terms of number of scientific publications (Moss et al., 2010). (2019). Evaluation of Ptarmigan Management with a Population Reconstruction Model. (2014). doi: 10.1111/gcb.14522, Moss, R., Storch, I., and Muller, M. (2010). However, because of the high combined loss-rates (i.e., combination of censoring and mortality), and the fact that the birds were spread across a huge area (see Results section) during summer and fall/early winter, we obtained relatively few locations in that period. Survival probability for late winter to start of the breeding season (February 1st–April 30th) was estimated at 0.7 (SE: 0.05), with natural survival estimated at 0.77 (SE: 0.05). doi: 10.2193/0022-541x(2006)70[1499:wseraa]2.0.co;2, Nilsen, E. B. This 60-inch radio strap is for use with carry cases and allows you to carry your radio cross-body. However, from an important part of their distribution – the mountainous areas across mainland Scandinavia – only aspects relating to population genetics (e.g., Costanzi and Steifetten, 2019), habitat use (Pedersen et al., 2013) and population dynamics based on harvest bag data (Kvasnes et al., 2010) has been studied. We conclude that (i) overwinter survival is relatively low but with no marked differences between years, age classes or sexes, and (ii) that there are distinct movements between winter and summer areas, and that few birds remained resident in the wintering area. Snow depth at the study area is 1–3 m deep during winter and snow cover persists from early October to late May. 2.
