Trypanosoma evansi, the agent of "surra," is a salivarian trypanosome, originating from Africa. It is thought to derive from Trypanosoma brucei by deletion of the maxicircle kinetoplastic DNA (genetic material required for cyclical development in tsetse flies). It is mostly mechanically transmitted by tabanids and stomoxes, initially to camels, in sub-Saharan area. The disease spread from North Africa towards the Middle East, Turkey, India, up to 53° North in Russia, across all South-East Asia, down to Indonesia and the Philippines, and it was also introduced by the conquistadores into Latin America. It can affect a very large range of domestic and wild hosts including camelids, equines, cattle, buffaloes, sheep, goats, pigs, dogs and other carnivores, deer, gazelles, and elephants. It found a new large range of wild and domestic hosts in Latin America, including reservoirs (capybaras) and biological vectors (vampire bats). Surra is a major disease in camels, equines, and dogs, in which it can often be fatal in the absence of treatment, and exhibits nonspecific clinical signs (anaemia, loss of weight, abortion, and death), which are variable from one host and one place to another; however, its immunosuppressive effects interfering with intercurrent diseases or vaccination campaigns might be its most significant and questionable aspect. © 2013 Marc Desquesnes et al.

Website are created for sharing information via internet, but today modern web browsers has the capability of catering features that our desktop computer applications and smartphone native applications can offer, that is why web applications are called as the future of both desktop and smartphone devices. Smartphone users are amazingly increasing in fast rate due to its lower prices and convenience, it has the capability to browse any web application which makes it a suitable device for documenting field data collection. In this article, we combined the promising features of web application (developed using Google Map API V3, jQuery, PHP & PostgreSQL) and the handiness of smartphones to achieve a real-time visualization of data collected during field surveys. The main objective of the presented application is to eliminate the time-consuming paper-based data collection during field surveys and speed up data delivery.

Climatic conditions are a prime candidate to explain local patterns of biodiversity and consequently there is great need of on-site climatic measurements. Among them, however, air humidity is notoriously difficult and time-consuming to measure, and it has been proposed that the epiphytic bryophyte cover can be used as an indicator of long-term air humidity conditions. Here we explore the utility of visually estimated epiphytic bryophyte cover on large canopy branches as a proxy for air humidity at 26 study sites in tropical forests where we measured microclimate for at least 12 months. Across all sites, bryophyte cover was weakly related to relative air humidity (R 2 = 0.17), but when we separated highland (1800-3500 m elevation) from lowland (<1800 m) sites, relative air humidity showed significant and distinct relations to bryophyte cover (R 2 = 0.36-0.62), whereas temperature was related to bryophyte cover only in the lowlands (R 2 = 0.36). We conclude that epiphytic bryophyte cover can be used as a proxy for air humidity if temperature and elevation are taken into account within a circumscribed study region, but might not be applicable for comparisons across extensive elevational gradients or wide differences in temperature. © 2012 Elsevier Ltd.

Acquisition of accurate forest biophysical parameters for forest management, inventory, biophysical modeling, and habitat analysis is labor intensive and time-consuming. Existence of airborne Light Detection and Ranging (LiDAR) data can supplement and supplant these. Derivatives produced from LiDAR such as Digital Terrain Model (DTM), Digital Surface Model (DSM), Normalized Digital Surface Model (nDSM) and Canopy Height Model (CHM) applied with algorithms are used to determine and estimate forest inventory parameters of Pine tree (Pinus carribean) plantation. This study was conducted to evaluate the capability of low dense LiDAR derived data to extract forest biophysical parameters from detecting and measuring individual trees in Compartment 87 of BFI, Siloo, Malitbog, Bukidnon. Using the inverse watershed segmentation in ArcGIS 10.2, 941 out of 961 (98%) actual standing trees in the field were detected. Results show that there is a positive relationship between the tree height and DBH at field measurement, thus tree height derived from LiDAR can supplement in estimating DBH. It was also observed that there is a relationship between the tree height and DBH derived from LiDAR and actual field measurement. Based on the findings, low dense LiDAR data shows the capability and limitations in extracting forest parameters.

The geomorphology of the watershed characterizes the formation of the river flood plains as it plays key roles on the dynamic hydrologic behavior in relation to flooding. To determine the extent of geomorphologic impact on the percent coverage of inundated area within the floodplain, this study analyzed 30 rivers across Mindanao with majority identified as critical base on the impaired biotic and biotic status due to socioeconomic roles and susceptibility, and potential threats to flooding by the Mindanao Rivers Reconstruction Task Force (MMRTF). Using ASTER Global DEM (ASTGTM) 30m Digital Elevation Model (DEM), watershed boundaries and river networks were determined using ArcGIS of Esri. Inundated areas of each watershed were likewise delineated based on the Mines and Geosciences Bureau (MGB) Maps. Regression analysis was conducted between inundated areas and the various geomorphologic values such as basin size, form factor, elongation ratio, circularity ratio, length of overland flow, basin relief, slope, number of stream, stream order, stream frequency, and stream density among others. Results revealed that inundated area is explained by the geomorphologic attributes of the watersheds. This implies that geomorphologic features of watershed are good indicators of flood prone zone within the landscape. Awareness on the geomorphologic characteristics of the watershed is helpful to the disaster risk reduction management council both at the local and national level particularly in prioritizing areas which need preventive mitigation measures and relief goods distribution for cost effective and efficient management operations.

The sporophyte and gametophyte development of Platycerium coronarium and P. grande were compared through ex situ propagation using in vitro culture technique and under greenhouse and field conditions. The morphology of the sporophyte and gametophyte, type of spore germination and prothallial development of P. coronarium and P. grande were documented. Gametophytes of P. coronarium and P. grande were cultured in vitro using different media. The gametophytes were then transferred and potted in sterile chopped Cyathea spp. (anonotong) roots and garden soil for sporophyte formation. Sporophytes (plantlets) of the two Platycerium species were attached on the slabs of anonotong and on branches and trunks of Swietenia macrophylla (mahogany) under greenhouse and field conditions. Sporophyte morphology of P. coronarium and P. grande varies but not their gametophyte morphology. P. coronarium and P. grande exhibited rapid spore germination and gametophyte development in both spore culture medium and Knudson C culture medium containing 2% glucose. Gametophytes of P. coronarium and P. grande transferred to potting medium produced more number of sporophytes while the gametophytes inside the culture media did not produce sporophytes. Sporophytes of P. grande attached on mahogany branches produced more number of leaves with bigger leaf area than those attached on anonotong slabs. Likewise, sporophytes of P. coronarium attached on mahogany branches and anonotong slabs did not develop new leaves during two weeks monitoring and are still in a period of adjustment to its environment. Sporophytes of P. grande grown or attached on the trunk of mahogany trees in the field and under shaded environment favored their growth. © 2009.
