We evaluated winter-territory mapping as a method for estimating fisher (Martes pennanti) density in a 210-km2 survey area in north-central Massachusetts in 1994 and 1995 by comparing estimates with simultaneous camera mark–resight estimates. Assuming intrasexual territoriality and accounting for all occupied habitat, territories of resident radio-marked fishers were mapped (mean = 54% of all t...

The stable isotope-mass balance method can provide useful water balance information in ungauged catchments. The method has been used to evaluate evaporation and water balance at two contrasting sites in northern Canada. Areally weighted evaporative discharge from an 850 km2 tundra catchment in south-central District of Keewatin is estimated to be about 7 % of total water discharge (= 16 mmlyr),...

Because the natural reservoir of Ebola virus remains unclear and disease outbreaks in humans have occurred only sporadically over a large region, forecasting when and where Ebola spillovers are most likely to occur constitutes a continuing and urgent public health challenge. We developed a statistical modeling approach that associates 37 human or great ape Ebola spillovers since 1982 with spati...

The current global projections of future sea level rise are the basis for developing inundation hazard maps. However, contributions from spatially variable coastal subsidence have generally not been considered in these projections. We use synthetic aperture radar interferometric measurements and global navigation satellite system data to show subsidence rates of less than 2 mm/year along most o...

Due to human activities, the Colombian Andean forests have lost about 85% of their original cover and very few species of primates persist in these fragmented landscapes. In the Western Cordillera, we evaluated the population density of Alouatta seniculus and Cebus capucinus by line transect census methodology, in a pre-montane isolated forest fragment of 559 ha, between 1200 to 1700 m of altit...

Preliminary results from the survey of golden jackals (Canis aureus) in Northern Dalmatia are presented. We used broadcasted jackal howls and monitored the response to determine the presence of jackal territorial groups. 19 jackal territorial groups were recorded in the NW part of Ravni kotari and 2 on Vir Island. The presence of territorial jackals on Pag Island could not be confirmed. For Rav...

A scale-invariance analysis of space and time rainfall events monitored by meteorological radar over the area of Rome (Italy) is proposed. The study of the scale-invariance properties of intense precipitation storms, particularly important in flood forecast and risk mitigation, allows to transfer rainfall information from the large scale predictive meteorological models to the small scale hydro...

Terrestrial gastropods were collected, 15 June to 25 November 1994, from beneath cardboard sheets on deer range in northeastern Minnesota (USA) and examined individually for larvae of Parelaphostrongylus tenuis, the meningeal worm of white-tailed deer (Odocoileus virginianus). Overall, 10 (0.08%) of 12,096 snails and slugs were infected with a mean (+/- SD) of 3.2 +/- 2.5 P. tenuis larvae. The ...
