Photogrammetric systems using video cameras were used to measure radial distances sightings during the SCANS-II, CODA and SOWER surveys. These surveys included of a variety species from harbour porpoise, at few hundred metres, large baleen whales greater than 10km. A total 910 initial with estimated reticles measured video, 7 × 50 (636) or 25× ‘Big Eye’ (274) binoculars, compared. Bearings also...

Recently, there have been efforts by stakeholders to monitor illegal mining (galamsey) activities, foster their formalization and reclaim the many abandoned wastelands in Ghana. However, limited information exists on the locations, abundance, scope and scale of galamsey types, which hinders the development of effective policy response. This study attempts to map and analyze the distribution pat...

The aim of the present study was to provide a preliminary description of habitat use by Guiana dolphins, Sotalia guianensis (Van Bénéden, 1864) in the Paranaguá Estuarine Complex (PEC), state of Paraná, Brazil. Approximately 124 km2 were surveyed by small boat from April 2006 to July 2008 in the following subsets of the PEC: Canal do Superagui (~28 km2); Pinheiros Bay (~34 km2); part of Laranje...

STOCK DEFINITION AND GEOGRAPHIC RANGE White-sided dolphins are found in temperate and sub-polar waters of the North Atlantic, primarily in continental shelf waters to the 100m depth contour. The species inhabits waters from central West Greenland to North Carolina (about 35 ̊N) and perhaps as far east as 43 ̊W (Evans 1987; Hamazaki 2002). Distribution of sightings, strandings and incidental takes...

While butterfly responses to climate change are well studied, detailed analyses of the seasonal dynamics of range expansion are few. Therefore, the seasonal range expansion of the butterfly Heliconius charithonia L. (Lepidoptera: Nymphalidae) was analyzed using a database of sightings and collection records dating from 1884 to 1992 from Texas. First and last sightings for each year were noted, ...

Five sea turtle species, all globally threatened, are found in southern Mozambican waters. Illegal hunting of foraging turtles, nest raiding and modification of coastal habitat are assumed to affect local sea turtle populations, but a lack of capacity and resource constraints hamper monitoring and compliance activities. Enlisting the recreational SCUBA diving community to report sea turtle sigh...

The nine-banded armadillo, Dasypus novemcinctus, has been expanding its range in the United State since the mid-1800s. There had been sporadic reports of this species in Illinois prior to 1990. I conducted a mail survey in 2003 of individuals knowledgeable about the fauna of southern Illinois to investigate the possible expansion of the armadillo into the state. I also sent questionnaires to an...
