The Impact

Long-distance migrants may be particularly vulnerable to climate change on both wintering and breeding grounds. However, the relative importance of climatic variables at different stages of the annual cycle is poorly understood, even in well-studied Palaearctic migrant species. Using a national dataset spanning 46 years, we investigate the impact of wintering ground precipitation and breeding ground temperature on breeding phenology and clutch size of 19 UK migrants. Although both spring temperature and arid zone precipitation were significantly correlated with laying date, the former accounted for 3.5 times more inter-annual variation. Neither climate variable strongly affected clutch size. Thus, although carry-over effects had some impact, they were weaker drivers of reproductive traits than conditions on the breeding grounds.

The space and habitat use patterns of the threatened Gaspé caribou (Rangifer tarandus caribou) were documented using telemetry. Between 1987 and 1992, 701 radiolocations were recorded, primarily for adult females (n = 28). Five habitats available to caribou (hardwood, immature, mature fir, mature spruce, alpine) are described and biomass of arboreal lichen, an important winter food source, is estimated. Regardless of sex and age, almost all locations (91%) were recorded within the limits of Gaspé Provincial Park. Home-range size of adult females averaged 148 km2 (convex polygon); 95% of adult female locations were within 107 km2 and 50% within 15 km2 (harmonic mean). Home-range sizes were small and did not vary seasonally or annually. Throughout the year caribou were located more frequently than expected at high elevations (> 915 m) and less frequently than expected at low elevations (0–685 m). Consequently, alpine habitat was used more frequently than expected. Caribou concentrated their activity in two distinct areas: the alpine plateaus of Mont Albert and Mont Jacques-Cartier. No caribou used both areas (with the exception of a lone female). These two caribou groups should be viewed as two subpopulations. The biomass of arboreal lichens was greatest in mature fir and spruce stands, with 50–60 kg/ha available at a height of 4 m. The altitudinal distribution of this resource may partly explain the strong selection of high-elevation sites made by caribou in winter. Our results also support the hypothesis that cow–calf groups remain at high elevations to reduce the risk of predation by coyotes (Canis latrans) and black bears (Ursus americanus). The proximity of mature forests and alpine habitat, at high elevations, in two areas of the park may explain the small extent of adult female home ranges and the segregation of Gaspé caribou into two groups.

Philodryas chamissonis, the Chilean long-tailed snake, is a diurnal predator mainly of Liolaemus lizards, but also of amphibians, birds, rodents and juvenile rabbits. Dromiciops gliroides (Colocolo opossum) is an arboreal marsupial endemic of temperate rainforest of southern South America. Little information is available about this marsupial's biology and ecology. Here we report the predation of one Colocolo opossum by an adult female P. chamissonis in a mixed Nothofagus forest, composed mainly by N. dombeyi, N. glauca and N. alpina trees, in the "Huemules de Niblinto" National Reserve, Nevados de Chillán, Chile. Since these two species have different activity and habitat use patterns, we discuss how this encounter may have occurred. Although it could just have been an opportunistic event, this finding provides insights into the different components of food chains in forest ecosystems of Chile.
