Abstract:

The vegetation of South Texas has changed from mesquite savanna to mixed mesquite–acacia (Prosopis–Acacia) shrubland over the last 150 years. Fire reduction, due to lack of fine fuel and suppression of naturally occurring fires, is cited as one of the primary causes for this vegetation shift. Fire behavior, primarily rate of spread and fire intensity, is poorly understood in these communities, so fire prescriptions have not been developed. We evaluated two current fire behavior systems (BEHAVE and the CSIRO fire spread and fire danger calculator) and three models developed for shrublands to de

Abstract:

Honey mesquite (Prosopis glandulosa Torr.) canopy responses to fire were measured following 20 single winter fires conducted in north Texas. Weather conditions during the fires, understory herbaceous fine fuel (fine fuel) amount and moisture content, fire temperature at 0 cm, 10-30 cm and 1-3 m above ground, and canopy responses were compared. Ten fires occurred on a site where fine fuel was a mixture of cool and warm season grasses (mixed site). The other 10 fires occurred on a site dominated by warm season grasses (warm site). When both sites were included in regressions, peak fire temperatu

Abstract:

While piñon woodlands cover much of arid North America, surprisingly little is known about the role of fire in maintaining piñon forest structure and species composition. The lack of region-specific fire regime data for piñon–juniper woodlands presents a roadblock to managers striving to implement process-based management. This study characterized piñon–juniper fire regimes and forest stand dynamics in Big Bend National Park (BIBE) and the Davis Mountains Preserve of the Nature Conservancy (DMTNC) in west Texas. Mean fire return intervals were 36.5 and 11.2 years for BIBE and DMTNC, respective

Abstract:

Wildfires are responsible for several civilians deaths and millions of dollars in property losses every year, on average. Wildfire containment is the result of an effectively performed initial attack. We formulate a two-stage stochastic integer programming standard response model for initial attack. The model assumes a known standard response needed to contain a fire of given size. The goal of the model is to contain as many fires as possible while minimizing the fixed rental and travel costs and the expected future operational costs.

Abstract:

In recent decades, the frequency of wildland fire incidents near residential areas has decreased but the number of acres burned has increased, in large part due to changes in forest management methods and further human encroachment in forested regions. There is much debate about whether the wood ash generated by these wildfires can significantly affect residential buildings outside the fire zone perimeter. This study investigates the distribution of ash, soot and char that are generated from wildfires and migrate into adjacent residential regions. For this purpose, a wildland fire in Bastrop,

Abstract The impacts of high-intensity wildfires on red imported fire ant Solenopsis invicta abundances in forest systems are currently unknown. The purpose of this study was to evaluate the effects of a high-intensity wildfire around pond edges on red imported fire ant captures in the Lost Pines ecoregion of Texas, which provides habitat for most of the remaining endangered Houston toads Bufo houstonensis. The red imported fire ant is a known predator of Houston toads, and thus there is interest in understanding the potential and realized impacts of this species on Houston toad survivorship.

Abstract:

Abstract. Phytoplankton taxonomy, pigment composition and photo-physiological state were studied in Galveston Bay (GB), Texas (USA), following the extreme flooding associated with Hurricane Harvey (25–29 August 2017) using field and satellite ocean color observations. The percentage of chlorophyll a (Chl a) in different phytoplankton groups was determined from a semi-analytical IOP (inherent optical property) inversion algorithm. The IOP inversion algorithm revealed the dominance of freshwater species (diatom, cyanobacteria and green algae) in the bay following the hurricane passage (29 Septem

Abstract:

Many studies have proposed resource dispersion as the main determinant of territory size in coyotes ( Canis latrans Say, 1823), but few have considered contender pressure as an alternative hypothesis. We tested for differences in rates of intra-territorial visitation, movement, and extra-territorial excursions between two populations of coyotes with large differences in territory sizes. We collected fine-scale (15 min) movement data of coyotes in southeastern Texas and south-central Idaho. Both populations were active for similar lengths of each day, but coyotes in Idaho had territories 10× la

Abstract:

ABSTRACT Olivella minuta is an abundant neogastropod on sandy beaches from Texas (USA) to southern Brazil. This study aimed to characterize and compare the feeding activity and diet of a Brazilian population of O. minuta in different tidal zones (intertidal and subtidal), and different tidal levels (high and low tides), with three combinations of tidal zone and level being studied (intertidal during low tide, intertidal during high tide and subtidal). The results showed that diet composition was generally similar among tidal conditions, with O. minuta being a generalist, feeding on 45 differen
