background: the different features of scorpions can be successfully described by their nesting and burrowing behaviors. there is little information about burrowing activity of iranian scorpions. methods: the current study was performed to compare the burrowing behavior between two burrowing iranian scorpions, scorpio maurus and odonthubutus bidentatus by describing 30 nests of each species rega...

We report on nests of radio-marked marbled murrelets (Brachyramphus marmoratus) nesting in unusual habitats in southwestern British Columbia. We found 1 confirmed and 2 probable marbled murrelet nest sites on cliffs. These represent the 1st substantiated accounts of ground nesting in this species south of Alaska. In addition, we found a marbled murrelet nesting in a 130 (?5)-yr-old red alder (A...

Populations of endangered Caribbean sea turtles are far more depleted than realized because current conservation assessments do not reflect historic nesting data. We used historical sources to analyze changes in the numbers of nesting populations and population sizes for green and hawksbill turtles on all known nesting beaches in the Caribbean over the past millennium. We present the first maps...

Titanosauria is a globally distributed clade of sometimes extremely large Mesozoic herbivorous sauropod dinosaurs. On the basis of current evidence these giant dinosaurs seem to have reproduced in specific and localized nesting sites. However, no investigations have been performed to understand the possible ecological and geological biases that acted for the selection of these nesting sites wor...

Coastal areas provide nesting habitat for marine turtles that is critical for the persistence of their populations. However, many coastal areas are highly affected by coastal development, which affects the reproductive success of marine turtles. Knowing the extent to which nesting areas are exposed to these threats is essential to guide management initiatives. This information is particularly i...

Species ranges often change in relation to multiple environmental and demographic factors. Innovative behaviors may affect these changes by facilitating the use of novel habitats, although this idea has been little explored. Here, we investigate the importance of behavior during range change, using a 25-year population expansion of Bonelli's eagle in southern Portugal. This unique population is...

—Habitat loss and pollution have been linked to declines of numerous freshwater turtle species, which are among the most endangered vertebrates in the world. We examined characteristics of nest sites of Common Snapping Turtles (Chelydra serpentina) located in a system modified by agricultural and industrial land use. We compared characteristics of 150 turtle nests and patterns of nest depredati...

Corridors that connect otherwise isolated habitats have often been proposed as a management strategy to mitigate negative effects of habitat fragmentation. Non-crop corridors may have the potential to enhance the connectivity for arthropod predators in cropland landscapes, especially for species that require multiple habitats, such as cavity-nesting wasps which use wooded habitat for nesting an...

Ecologists have long recognized the influence that environmental conditions have on abundance and range extent of animal species. We used the northern bobwhite (Colinus virginianus; hereafter bobwhite) as a model species for studying how microclimates serve as refuge against severe weather conditions. This species serves as an indicator or umbrella species for other sensitive ground-nesting, gr...
