1 2 Quantification of forest structure is important for developing a better 3 understanding of how forest ecosystems function. Additionally, estimation of 4 forest structural attributes such as aboveground biomass is an important step in 5 identifying the amount of carbon in terrestrial vegetation pools and is central to 6 global carbon cycle studies.(More)
Advances in remote sensing and space-based imaging have led to an increased understanding of past settlements and landscape use, but e until now e the images in tropical regions have not been detailed enough to provide datasets that permitted the computation of digital elevation models for heavily forested and hilly terrain. The application of airborne(More)
Intestinal nematodes affecting dogs, i.e. roundworms, hookworms and whipworms, have a relevant health-risk impact for animals and, for most of them, for human beings. Both dogs and humans are typically infected by ingesting infective stages, (i.e. larvated eggs or larvae) present in the environment. The existence of a high rate of soil and grass(More)
Spatial patterns of forest canopies are fractal as they exhibit variation over a continuum of scales. A measure of fractal dimension of a forested landscape represents the spatial summation of physiologic (leaf-level), demographic (population-level), and abiotic (e.g., edaphic) processes, as well as exogenous disturbances (e.g., ®re and hurricane) and thus(More)
Dirofilaria repens is the causative agent of subcutaneous dirofilariosis of dogs, other animals and humans. This nematode is transmitted by mosquitoes of Aedes, Anopheles and Culex genera. In dogs, the parasite may cause subclinical infection or cutaneous signs. Recently, D. repens has emerged and spread in different geographical areas, with an increase of(More)
This survey examines the experience and opinion of veterinarians with canine heartworm (HW; Dirofilaria immitis) infection in non-endemic and endemic areas of Europe. A questionnaire was distributed by e-mail to veterinary practitioners within non-endemic countries including UK, Germany, and Netherlands,non-endemic regions of France, Spain, Italy and(More)
The current BAR catalogue with details of all titles in print, prices and means of payment is available free from Hadrian Books or may be downloaded from www. Abstract To understand the social, political, economic, and ecological implications of historic land use patterns of Caracol, one of the largest (~200 sq km) Maya archaeological sites, we are(More)
This study used an affordable ground-based portable LiDAR system to provide an understanding of the structural differences between old-growth and secondary-growth Southeastern pine. It provided insight into the strengths and weaknesses in the structural determination of portable systems in contrast to airborne LiDAR systems. Portable LiDAR height profiles(More)
Dogs with chronic inflammation, including those with heartworm being managed with macrocyclic lactones and doxycycline (slow kill, SK), may develop immune complexes that block detection of Dirofilaria immitis antigen on commercial tests. To determine if SK could result in development of false-negative antigen tests, we collected serum samples from dogs that(More)
Previous studies have shown that canopy metrics from lidar data are highly correlated with aboveground biomass in a variety of closed-canopy forests, however the generality of these site-specific relationships has remained untested. In this study, we compare relationships between lidar canopy metrics and forest structural summaries from a tropical wet(More)
