The faunas of parasitic helminths and arthropods of 87 Sherman's fox squirrels (Sciurus niger shermani) and 32 Big Cypress fox squirrels (Sciurus niger avicennia) collected from Florida (USA) over a 6-yr period (1988 to 1993) were compared. One acanthocephalan, one cestode, nine nematodes, one flea, three sucking lice, three mites, one tick, and one dipteran larva were identified. Citellinema b...

Alaska yellow-cedar has declined in Southeast Alaska over the past 100 years, resulting in half a million acres of dead or dying trees. The natural decay resistance of Alaska yellow-cedar means that many of these trees are still merchantable. However, the topography of Southeast Alaska is such that selectively harvesting Alaska yellow-cedar may often require helicopter-yarding. This paper tests...

i Abstract In the present study, the effect of the trees in windbreaks on the leeward airflow is investigated, for the first time, employing numerical models. Different arrangements of windbreaks have been considered: (i) a single row of cypress trees, (ii) two rows of cypress trees and (iii) two rows of cypress trees with a low hedge that represent shrubs in the first row. The RANS equations h...

Increased herbicide use in silviculture over the last several decades has led to concern over potential water contamination, which may affect biotic health. In the southeastern United States, pine flatwoods are important for timber production and are often interspersed with cypress wetlands. Cypress domes are isolated, shallow basins that collect surficial waters from adjacent forested areas an...

To analyse the 137Cs distribution and migration under various fractions of organic matter layers, this study investigated easily recognizable, originally shaped L-fractions, not early fermented fragmented F-fractions, both oak (Quercus serrata) cedar (Cryptomeria japonica) sampled from Osawa watershed sites at Nihonmatsu City, Fukushima Prefecture, Japan. The materials were put on top soil colu...

OBJECTIVE To assess the effect of a single aeroallergen on Internet search activity in 3 distinct geographic regions over time. STUDY DESIGN A retrospective time series analysis. SETTING Tertiary academic medical center. METHODS Mountain Cedar pollen counts spanning the periods from 2011 to 2014 were collected for San Antonio, Dallas-Ft Worth, and Houston metro regions (Texas). Google sea...

We present cedar , a software framework for the implementation and simulation of embodied cognitive models based on Dynamic Field Theory (DFT). DFT is a neurally inspired theoretical framework that integrates perception, action, and cognition. cedar captures the power of DFT in software by facilitating the process of software development for embodied cognitive systems, both artificial and as mo...

The biocidal activity of three steam distilled wood essential oils-incense cedar, Calocedrus decurrens (Torr.) Florin; Port-Orford-cedar, Chamaecyparis lawsoniana (A. Murr.) Parl.; and western juniper, Juniperus occidentalis (Hook)--were evaluated against adult Aedes aegypti (L.) (Diptera: Culicidae) and Xenopsylla cheopis (Rothchild) (Siphonaptera: Pulicidae) and nymphal Ixodes scapularis Say ...
