Abstract Forest edges have been well studied in temperate and tropical forests, but less so open canopy forests. We investigated edge influence on plant species diversity soil properties sparse oak forest fragments. Data were collected along three transects from the to interior of small (under 10 ha) large (over fragments Kermanshah Province, Iran. measured herbaceous plants (<0.5 m heig...

Obtaining reliable population estimates is crucial to monitoring endangered species and developing recovery strategies. The palila (Loxioides bailleui) is an endangered seed-eating Hawaiian honeycreeper restricted to the subalpine forests of Mauna Kea, a volcano on the island of Hawai‘i, USA. The species is vulnerable to extinction primarily because .90% of the population is concentrated in ,30...

An intense debate exists on the effects of post-fire salvage logging on plant community regeneration, but scant data are available derived from experimental studies. We analyzed the effects of salvage logging on plant community regeneration in terms of species richness, diversity, cover, and composition by experimentally managing a burnt forest on a Mediterranean mountain (Sierra Nevada, S Spai...

This study presents data on woody plant species richness and diversity of an inaccessible dry forest Tula Mountains Woodland (TMW) located in the northeast Nigeria. TMW supports a minimally disturbed mosaic forest-woodland. We sampled 190 plots size 0.01-ha, spaced 50 m apart series line transects. found total 133 belonging to 88 genera 39 families 1.9 ha area total. Out species, 120 were ident...

Many studies examining the food retail environment rely on geographic information system (GIS) databases for location information. The purpose of this study was to validate information provided by two GIS databases, comparing the positional accuracy of food service places within a 1 km circular buffer surrounding 34 schools in Ontario, Canada. A commercial database (InfoCanada) and an online da...

A method for measuring and mapping the location of blackbird (Icterinae) damage to ripening rice over time was developed and employed in 7 commercial rice fields ranging from 20.6 to 47.4 ha in Matagorda County, Texas, during the 1985 and 1986 growing seasons. Ten evenly-spaced transects were established perpendicular to the longest side of the field and each transect was sampled at pre-determi...

Science and technological developments provide new opportunities to exploit aquatic resource. Hence, it is important to understand biotic and abiotic conditions of aquatic ecosystems. Objective of this Paper is to report findings of the study of nitrate and phosphate contents of water and effects of other physicalchemical parameters in the southwest regions of the Caspian Sea in the spring and ...

Understanding ecological processes is a prerequisite for the management of rangelands; therefore, recognition of the relationship between environmental factors and vegetation is very important. The present research aims to investigate environmental and management factors affecting rangeland vegetation distribution in Saral rangelands of Kurdistan province, Iran, in 2017. Sampling was done...

Coral reefs are one of the most diverse marine ecosystems, providing numerous ecosystem services. This present study investigated relationship between coral reef condition and diversity abundance fishes, on a heavily fished East African at Gazi Bay, Kenya. Underwater visual censuses were conducted thirty 50 × 5 m belt transects to assess fishes. In parallel, 25-m length each same was recorded w...
