a r t i c l e i n f o Keywords: KAI GIS GRASS Free and Open Source Wildlife monitoring Mountain hare Kilometric Abundance Index (KAI) is a common measure used in wildlife studies because it allows a straightforward comparison of species abundance in different sites or at different times. KAI expresses the ratio of the total number of individuals (or of signs of presence) observed along a transe...

In this paper the occurrence, distribution and abundance of cetaceans in offshore waters Onslow Bay, North Carolina, USA is described. Between June 2007 2010 monthly aerial shipboard line-transect surveys were conducted along ten 74km transects placed perpendicular to shelf break. total 42,676km trackline (218 sightings) 5,209km vessel (100 observed. Seven species observed, but fauna was domina...

A localised aggregation of blue whales, which may be pygmy whales (B. m. brevicauda), occurs in southern Australian coastal waters (between 139°45AE-143°E) during summer and autumn (December-May), where they feed on krill (Nyctiphanes australis), a species often forms surface swarms. While the abundance using this area is unknown, up to 32 have been sighted individual aerial surveys. Krill appe...

Introduction: Nowadays, excessive computer use in the workplace has raised concerns about the health status of VDT workers, particularly complaints about eye discomforts. Due to the importance of the eyelids and eye closure parameters on eye health during computer works and the direct effect of monitor height on these parameters, this study was aimed to examine the effect of different monitor h...

These six regions represent relatively discrete subpopulations, fidelity to which is determined matrilineally (Clapham and Mayo 1987). Recent genetic analysis of mitochondrial DNA (mtDNA) has indicated that this fidelity has persisted over an evolutionary timescale in at least the Icelandic and Norwegian feeding grounds (Palsbøll et al. 1995, Larsen et al. 1996). Genetic partitioning is not evi...

The relationship between beaked whales and certain anthropogenic sounds remains poorly understood and of great interest. Although Cuvier's beaked whales (Ziphius cavirostris) are widely distributed, little is known of their behavior and population structure throughout much of their range. We conducted a series of five combined visual-acoustic marine mammal surveys from 2006 to 2008 in the south...

STOCK DEFINITION AND GEOGRAPHIC RANGE Pantropical spotted dolphins are primarily found in tropical and subtropical waters worldwide (Perrin et al. 2009). Much of what is known about the species in the North Pacific has been learned from specimens obtained in the large directed fishery in Japan and in the eastern tropical Pacific (ETP) tuna purse-seine fishery (Perrin et al. 2009). Spotted dolph...

Thermal infrared emission and thermophysical modeling techniques are powerful tools in deciphering the surface properties of asteroids. The near-Earth asteroid (3200) Phaethon is an active with a very small perihelion distance likely source Geminid meteor shower. We estimate interpret thermal inertia this extraordinary using observations that span ten distinct sightings. variation over these si...

Introduction: In this paper, by complete definition of human eye containing the various parts and their materials, the difference between this model and a homogeneous water phantom are compared for two ophthalmic plaques using 125I and 103Pd. Material and methods: The simulation of the two phantoms were performed in the MCNP-4C code and by using the geometry of a three-dimensional eye, differen...
