“…Impor-335 tantly, while fire and grazing did directly influence nest site selection, 336 they were less important in determining nest survival and, instead, 337 local weather variables appear to be the most influential. These results 338 are consistent with an emerging body of evidence emphasizing the im-339 portance of thermal environments and climatic conditions on gallina-340 ceous bird habitat use and survival(Guthery et al, 2005; Fields et al, 341 2006; Grisham et al, 2013;Larsson et al, 2013;Hovick et al, 2014c).342Our findings reveal that increased solar radiation (indicating fewer 343 clouds and brighter days) decreased the probability of nest survival.…”

“…Northern Bobwhite showed similar hyperthermic avoidance behavior when selecting mid-day coverts in Texas by using areas of greater vegetation growth (Guthery et al 2005), and Lesser Prairie Chickens (Tympanuchus pallidicinctus) in Oklahoma and New Mexico selected areas that were more exposed during cool seasons and less exposed during warm seasons, presumably to thermoregulate through more or less exposure to solar radiation (Larson et al 2013). Separating thermal habitat selection from predator avoidance behavior is highly confounded and complicated as it appears that areas of greater biomass are used for both (Guthery et al 2005), but it is not unlikely that predator avoidance and hyperthermic avoidance behavior are acting in synergy and that management practices focused on biomass retention would benefit populations by improving conditions for both.…”

Landscapes as a moderator of thermal extremes: a case study from an imperiled grouse

Abstract. The impacts of climate driven change on ecosystem processes and biodiversity are pervasive and still not fully understood. Biodiversity loss, range shifts, and phenological mismatches are all issues associated with a changing climate that are having significant impacts on individuals and ecosystems alike. Investigating and identifying effective management strategies that can conserve vulnerable species should be the focus of current and future climate change research. We investigated thermal properties of habitat for an imperiled grouse (Greater Prairie-chicken; Tympanuchus cupido) in tallgrass prairie characterized by heterogeneous fire and grazing (the fire-grazing interaction). We examined operative temperature at varying scales relevant to grouse and used historic and forecasted climate data to estimate thermal stress during nesting activities. We found that heterogeneous grasslands have high thermal variability with operative temperature ranging as much as 238C across the landscape. Grouse exhibited strong selection for cooler thermal environments as nest sites were as much as 88C cooler than the surrounding landscape, and fine-scale differences in thermal environments were nearly 48C cooler than sites within 2 m of nests. Additionally, forecasted climate scenarios indicate grouse will experience 2-4 times the number of hours above thermal stress thresholds, emphasizing the need for informed conservation management. Overall, these data provide evidence that variation in grassland structure resulting from the fire-grazing interaction may be important in moderating thermal environments and highlights the complex and interactive effects of restored ecological processes on ecosystems.

“…In subsequent stages, the species may use different tactics to avoid predators, such as using vegetation cover during the nesting and brood rearing phase (Kirol et al 2012;Latif et al 2012;Suwanrat et al 2014). When displaying at scrapes there might be a trade-off between successful mating and predator risk similar to that in male Lesser Prairie-chicken (Tympanuchus pallidicinctus), which selects open areas for leks to display for females in spring, but also suffer from peak mortality at the same time (Hagen et al 2005;Larsson et al 2013).…”

“…For example, loss of specific microhabitats may prevent males from exhibiting appropriate display behaviour, e.g. the Black Grouse (Lyrurus tetrix) (Patthey et al 2012) and the Lesser Prairie-chicken (Tympanuchus pallidicinctus) (Larsson et al 2013). Furthermore, knowledge of the relationship between microhabitat use and predation risk may allow insights into variation in survival (DeCesare et al 2014).…”

Spatial distribution of display sites of Grey Peacock-pheasant in relation to micro-habitat and predators during the breeding season

Background:The destruction and fragmentation of forest in Southeast Asia is accelerating biodiversity loss, resulting in a range of management and conservation actions. For some species, a detailed understanding of microhabitat selection is critical for this, especially in the breeding season. Methods:To understand the factors that explain how specific habitats are used by the Grey Peacock-pheasant (Polyplectron bicalcaratum) in the breeding season, we used camera trapping and microhabitat sampling to assess the microhabitat selection of males. We also looked at their interaction with predators in an area of 1200 m × 1200 m at the Huai Kha Khaeng Wildlife Sanctuary, Thailand, between January and May 2013. Results:We show that display scrapes are situated on flatter open areas with small saplings and some vines, typified by low horizontal understory density. We hypothesise that this allows a trade-off between courtship display and the avoidance of predators. Our study showed that the position of Grey Peacock-pheasant display scrapes regularly overlapped with predators within the same microhabitat. We hypothesise that the species' behavioural responses to temporal variation in predation risk allows them to avoid most predators.
