Variability of green biomass quantity in plant communities found in study transects established along selected traffic routes in Białystok was studied. The study was conducted in a total of four transects including three in non-forest plant communities and one in a forest community located in the vicinity of Białystok’s main outbound roads. The effect of different distance of the study fields f...

Wind, in the duration of its erosional process, affects considerable changes in a grain's morphologyfrom its removal (detachment) step to sedimentation. In other word, a grain undergoes its gradualevolution during the transit process. In this project, the maturation of Aeolian sand grains had beenstudied upon as based on texture maturity indicator which includes: sorting, mean size grain, round...

The percentage cover and distribution of scleractinian corals were studied at two Iranian islands in the Persian Gulf. Survey techniques involved the use of 20-m line transects placed at 4-9 m depth interval, parallel to the shore. GIS based maps were employed to show the distribution of hard corals. In Farurgan Island, hard coral cover was concentrated in the west and north-west of the island,...

We conducted at-sea line transect surveys for Marbled Murrelets (Brachyramphus marmoratus) to determine density off the coast of central California and to explore the utility of various survey protocols. Surveys were designed to compare line versus strip transect methods, and reveal the effects of distance from shore, viewing conditions and seasonal trends on density estimates. On consecutive d...

The risk of Lyme disease for humans in the eastern United States is dependent on the density of host-seeking Ixodes scapularis Say nymphal stage ticks infected with Borrelia burgdorferi. Although many local and regional studies have estimated Lyme disease risk using these parameters, this is the first large-scale study using a standardized methodology. Density of host-seeking I. scapularis nymp...

Montane habitats are characterized by predictably rapid heterogeneity along elevational gradients and are useful for investigating the consequences of environmental heterogeneity for local adaptation and population genetic structure. Food-caching mountain chickadees inhabit a continuous elevation gradient in the Sierra Nevada, and birds living at harsher, high elevations have better spatial mem...
