Reliable Refuge: Two Sky Island Scorpion Species Select Larger, Thermally Stable Retreat Sites

Reliable Refuge: Two Sky Island Scorpion Species Select Larger, Thermally Stable Retreat Sites

Sky island scorpions shelter under rocks and other surface debris, but, as with other scorpions, it is unclear whether these species select retreat sites randomly. Furthermore, little is known about the thermal preferences of scorpions, and no research has been done to identify whether reproductive condition might influence retreat site selection. The objectives were to (1) identify physical or...

How Do Nocturnal Snakes Select Diurnal Retreat Sites ?

Theoretical and empirical studies of habitat selection suggest that reptiles should use ‘‘fixed’’ structural features (perch diameter, vegetation) or light intensity (sun and shade) to select thermally suitable microhabitats. But how do nocturnal species select thermally suitable diurnal retreat sites at night in the absence of visual cues? To investigate this question, we studied habitat selec...

Island refuge

Wildlife conservation in Turkey does not get a high priority. Yet the country lies in a key location for birds migrating from Asia and Africa to Europe. Wildlife reserves exist but often have worryingly little support. So the development of Lake Kuyucuk in the Kars province of eastern Turkey as a wildlife reserve for thousands of birds of more than two hundred species, while also supporting loc...

A Two-Fluid Thermally-Stable Cooling Flow Model

A new model for cooling flows in X-ray clusters, capable of naturally explaining salient features observed, is proposed. The only requirement is that a significant relativistic component, in the form of cosmic rays (CR), be present in the intra-cluster medium and significantly frozen to the thermal gas. Such an addition qualitatively alters the conventional isobaric thermal instability criterio...
