Abstract Wild sheep (Ovis spp.) are of conservation concern throughout the Middle East. Little is known, however, about the natural history or ecology of this taxon. To better understand size relationships among wild sheep occupying Iran, we analyzed results from 120 females collected from widely separated ecosystems. Morphometrics and body weights for all age categories of females occupying the Khosh-Yeilagh Wildlife Refuge in northeastern Iran were larger than those for the same age classes of females occupying Bamou National Park in southwestern Iran. Females from Bamou National Park, however, obtained adult body weight (x‾ = 25.8 ± 2.47 [SD] kg) at an earlier age than those from the Khosh-Yeilagh Wildlife Refuge (x‾ = 36.6 ± 3.21 kg). Ecological differences between these two areas suggest that net primary productivity, which is a function of numerous climatic and geographical factors, has been a primary force contributing to these results. Weights and measurements reported here provide the basic information for additional, more detailed research necessary to fully understand the evolutionary significance and management implications of these differences in body size and emphasize the conservation value of even the most basic natural history information.

Booderee National Park at Jervis Bay, 200km south of Sydney, attracts over 450,000 visitors each year. The park has many special features, including dramatic wave cut platforms and sea caves, some of the whitest beach sands in Australia, and very high densities of native predators such as the Powerful Owl and the Diamond Python. This book outlines the biology and ecology of Booderee National Park. Booderee packs an extraordinary level of biodiversity into a small area (roughly 6500 hectares), with more than 260 species of terrestrial vertebrates and over 625 species of plants. It is home to species of significant conservation concern, such as the globally endangered Eastern Bristlebird for which the park is one of its last and most important strongholds. The diversity of vegetation is also astounding: in some parts of the park, it is possible to walk from ankle-high sedgelands, through woodlands and forest and into subtropical rainforest in less than 150 metres. The book highlights how Booderee National Park is a functional natural ecosystem and, in turn, how management practices aim to improve environmental conditions and promote biodiversity conservation. Richly illustrated with colour images from award-winning photographer Esther Beaton, it will delight visitors to the park as well as anyone with an interest in natural history.

Eight in-service teachers and two instructors engaged in an inquiry-based geology field course from June 14 to 29, 2014 through Wyoming, South Dakota, and Nebraska. This team of learners spent three days in mid-June working in the Grand Teton National Park area. The UW-NPS facilities provide an excellent opportunity for participants to discover the natural history of the Teton Range, as well as close-out a few projects while sitting in a real chair, at a real table, a welcome change from our usual campground setting.

This project was designed to determine the optimum population size for bison in the Theodore Roosevelt National Park (TRNP) by fulfilling the following objectives: 1. Delineate primary and secondary areas of bison use. 2. Determine net primary productivity for major range sites within primary and secondary use areas. 3. Determine the general seasonal food habits of bison in TRNP. 4. Determine range trends under present population density of bison and the maximum carrying capacity of primary use areas. 5. Integrate range trend and carrying capacity estimates with management priorities for bison on the TRNP.

Ctenus medius Keyserling, 1891 is a common species in several spots of Mata Atlântica, however there is a great lack of studies in all aspects of its natural history. This work aims to elucidate aspects of ecotope preference compared to large spiders, and to provide data on the development of chromatic patterns during its life cycle. The observations on the behavior of C. medius were done in the campus of Centro Universitário de Barra Mansa (UBM) by means of observations and nocturnal collections using cap lamps. For observations on the development of chromatic patterns, spiderlings raised in laboratory, hatched from an oviposition of a female from campus of UBM, and others spiderlings collected in field were used. The field observations indicate that: C. medius seems to prefer ecotopes characterized by dense shrub vegetation or herbal undergrowth; Lycosa erythrognatha and L. nordeskioldii seems to prefer open sites; Phoneutria nigriventer seems to prefer shrub vegetation and anthropogenic ecotopes as rubbish hills; Ancylometes sp. seems to prefer ecotopes near streams. Concerning chromatic patterns, it was observed that males and females show well distinct patterns during the last two instars, allowing distinction by sex without the use of a microscope. Through chromatic patterns it was also possible to draw a distinction between C. medius and C. ornatus longer that 3 mm cephalothorax width. 69 specimens of C. medius (males and females) collected in the campus of UBM did not show a striking polymorphism in chromatic pattern, but one among 7 adult females collected in National Park of Itatiaia, showed a distinct chromatic pattern.
