Subject:
Circus; agricultural land; birds; breeding; clutch size; correlation; crops; eggs; farming systems; gender differences; harvest date; nesting; nests; sex ratio; weather; Poland
Abstract:
... In 2005–2011 active conservation and study on the population of the Montagu’s Harrier was conducted in the farmland areas of east-central Poland. The population was estimated at 240–270 breeding pairs and its size was stable. The mean clutch size was estimated at 3.71 eggs per breeding pair. The number of fledglings was 1.24 per nest and 2.6 per successful breeding pair. There were no significant ...

dry environmental conditions; ecology; nocturnal activity; rodents; surveys; zoology; Iran
Abstract:
... Allactaga hotsoni firouzi is endemic to a restricted area in Isfahan Province, Iran. However, this rodent has hardly been studied. Density estimates are essential for the effective design of conservation strategies. Given the nocturnal behaviour of A . h . firouzi , we conducted spotlight surveys to determine the relative abundance of this rodent. The same approach was used to assess the influence ...

Abstract:
... Some aspects of growth and reproductive biology of Hepsetus odoe , a commercial fish species from Lake Eleiyele, were investigated from October 2010 to April 2011 to enhance effective management and sustainable exploitation. The pattern of growth was determined from the length-weight relationship (LWR) and the condition factor (K). The reproductive features studied included fecundity, the gonadoso ...

Abstract:
... This paper is aimed at comparing the influence of diet, effect of crowding and temperature on the growth of larval stages in a pest grasshopper Acrida exaltata Walker (Orthoptera: Acrididae). It was found that Brassica oleracea var. botrytis was mostly preferred by both sexes with the minimum hopper developmental period of 33.20 ± 0.54 days in males and 38.40 ± 0.98 days in females, while Saccharu ...
