Bat species richness in Neotropical localities is generally higher than that of any other group of mammals, and surveys of local bat assemblages may provide useful data for conservation management plans. Although the bat fauna of the Rio de Janeiro state is currently one of the best known in Brazil, there are several localities not adequately surveyed yet, and most of them are in the mountainou...

We present EU-Forest, a dataset that integrates and extends by almost one order of magnitude the publicly available information on European tree species distribution. The core of our dataset (~96% of the occurrence records) came from an unpublished, large database harmonising forest plot surveys from National Forest Inventories on an INSPIRE-compliant 1 km×1 km grid. These new data can potentia...

Point counts and mist-net surveys were employed to study the winter distri­ bution of nearctic migratory landbirds in Mexico’s Yucatan Peninsula. Overwintering mi­ grants comprised 42 regularly occurring species, and accounted for 30-58% (mean = 41%) of the individual birds encountered in surveys of a wide range of natural and disturbed habitats. Some migratory species were encountered most fre...

The invasive insect pest Adelges tsugae (Hemlock Woolly Adelgid) threatens the ecologically unique Tsuga canadensis (Eastern Hemlock)-dominated forest type throughout its range. Relatively little is known about how the loss of this forest type will affect the relative abundance of amphibians. This study assessed the relative abundance of the juvenile phase of Notophthalmus viridescens viridesce...

The properties of a variable area sampling technique, by which the observer varies the searchradius to obtain approximately a prescribed number of woody plants in each tier measured, were determined by (i) comparison of fixed area and variable area sampling of a computer-mapped shrub population; (ii) comparison of results from fixed area and variable area sampling of woody plants exceeding abou...

Opinions about public lands and the actions of private non-industrial forest owners in the western United States play important roles in forested landscape management as both public and private forests face increasing risks from large wildfires, pests and disease. This work presents the responses from two surveys, a random-sample telephone survey of more than 1500 residents and a mail survey ta...

Ecosystem services provided by forests (e.g., nutrient cycling) are critical in midwestern landscapes. We conducted collaborative workshops with forest landowners and management professionals using specific strategies to provide information about nutrient dynamics in forests and learn about goals/obstacles for forest management in Iowa. Preparticipation surveys assessed knowledge and goals and ...
