OBJECTIVES (1) To determine the effect of age, height, weight, breed, sex, and specific use on the prevalence of idiopathic left laryngeal hemiplegia (ILH) in a population of draft performance horses; (2) to determine the association between tracheal mucus and laryngeal dysfunction, and the prevalence of exercise-induced pulmonary hemorrhage (EIPH) in a population of draft performance horses. ...

The seven cases presented here were diagnosed at the Equine Clinic, University of Veterinary and Pharmaceutical Sciences, Brno, Czech Republic between the years 2002 and 2008. The age range of affected horses was from 10 months to 10 years and included four Thoroughbreds and three warm blooded horses. The horses showed different clinical signs – recurrent or acute colic, poor appetite, frequent...

the aim of this study was to determine the seroprevalence of toxoplasma gondii in mares and stallionsin the province of ankara. sera from 168 clinically healthy horses were tested for the presence oftoxoplasma gondii antibodies using the sabin feldman dye test. toxoplasma gondii infection wasdetermined in 62 (36.9%) of 168 horses with the titers ranging from 1:16 to 1:256.

Water use and carbon exchange of a red oak-dominated (Quercus rubra L.) forest and an eastern hemlock-dominated (Tsuga canadensis L.) forest, each located within the Harvard Forest in north-central Massachusetts, were measured for 2 years by the eddy flux method. Water use by the red oak forest reached 4 mm day(-1), compared to a maximum of 2 mm day(-1) by the eastern hemlock forest. Maximal ca...

Fuel-reduction/forest restoration treatments that consist of thinning followed by prescribed burning are becoming increasingly important land management actions that likely affect various wildlife species. To assess potential effects on bark-gleaning birds, we compared the foraging patterns of five cavity-nesting species in thinned and burned ponderosa pine (Pinus ponderosa) forest sites and co...

Differential habitat use and intraguild competition are both thought to be important drivers of animal population sizes and distributions. Habitat associations for individual species are well-established, and interactions between particular pairs of species have been highlighted in many focal studies. However, community-wide assessments of the relative strengths of these two factors have not be...

Wildfire size, frequency, and severity are increasing in the Alaskan boreal forest in response to climate warming. One of the potential impacts of this changing fire regime is the alteration of successional trajectories, from black spruce to mixed stands dominated by aspen, a vegetation composition not experienced since the early Holocene. Such changes in vegetation composition may consequently...

Increasing interest in non-timber forest products (NTFPs) has led to their greater recognition in sustainable forest management planning. This is evident in local resource management plans for the Robson Valley in east-central British Columbia, where public input shows strong support for the sustainable development of NTFP harvesting. However, information needed to develop sustainable managemen...

Techniques are presented to progressively approximate and compress in a lossless manner two-colored (i.e. binary) 3D objects (as well as objects of arbitrary dimensionality). The objects are represented by a region octree implemented using a pointerless representation based on locational codes. Approximation is achieved through the use of a forest. This method labels the internal nodes of the o...
