Book Synopsis The Laguna Madre of Texas and Tamaulipas, Revised Edition by : Kim Withers
Download or read book The Laguna Madre of Texas and Tamaulipas, Revised Edition written by Kim Withers and published by Texas A&M University Press. This book was released on 2024-06-03 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Laguna Madre is the only hypersaline coastal lagoon on the North American continent and only one of five worldwide. The lagoon is renowned for its vast seagrass meadows, huge wintering redhead population, and bountiful fishing grounds. In 2000, the Nature Conservancy, whose mission is the conservation of biodiversity through protection of habitat, recognized the need to amass all known information about the Laguna Madre and implement a science-based conservation agenda. From those efforts came the first edition of this book. Now completely revised and updated, this second edition of The Laguna Madre of Texas and Tamaulipas is the culmination of two decades of additional research and continued conservation efforts in the region. Nearly 100 years of literature on the Laguna Madre and surrounding environments has been synthesized here. With 150 figures and illustrations, the book takes a broad and comprehensive look at both the Texan and Tamaulipan Laguna Madre. The value of this book for scientists, conservationists, resource managers, and policy makers involved in the future of the Texas and Mexico coasts is clear. Coastal residents, birders, anglers, and nature lovers who want to learn about and take care of the Laguna Madre will find this to be an indispensable guide.
Book Synopsis Comparison of Fine Scale Vegetative Parameters at Active and Inactive Gulf Coast Kangaroo Rat Burrow Sites by : Meagan Marie Bell
Download or read book Comparison of Fine Scale Vegetative Parameters at Active and Inactive Gulf Coast Kangaroo Rat Burrow Sites written by Meagan Marie Bell and published by . This book was released on 2017 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulf Coast kangaroo rat (Dipodomys compactus) is an endemic Texas species belonging to the family Heteromyidae. Many heteromyid species, especially kangaroo rats, are highly specialized nocturnal granivorous rodents with external fur lined cheek pouches, bipedal cursorial locomotion, and adaptations for arid and desert conditions. Despite being one of six Texas endemic mammals, few studies have been conducted on habitat requirements, movement, and basic ecology of the Gulf Coast kangaroo rat with no long-term research. From April 2016 to March 2017, I have seasonally monitored burrowing activity of Gulf Coast kangaroo rats and recorded vegetative parameters at 63 randomly selected sites on a working cattle and wildlife ranch located in Guadalupe County, Texas. Sites with active burrows or a history of occupancy were monitored monthly. Within a 10-m radius plot at each site and using the Daubenmire frame cover estimate technique, I recorded percent cover of the following cover classes: bare ground, standing dead vegetation, litter, living grass, and living forbs. Additionally, I identified to the lowest taxonomic level the dominant live green grass and forb species in each Daubenmire frame and recorded the height of the tallest live grass, live forb, and standing dead vegetation. Using a spherical densitometer, I determined the percent woody canopy coverage at each Daubenmire frame. Twenty-two of 63 sites were occupied. Using Nested ANOVA, I found significantly greater cover of litter, taller standing dead, and taller grass (p

This book was released on 2011 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulf-coast kangaroo rat (Dipodomys compactus) is characteristic of the arid ecosystems of South Texas and the barrier islands. It is listed by Texas Parks and Wildlife Department as a species of concern and is the only member of the family Heteromyidae found on Mustang Island, North and South Padre islands, Texas, and the barrier islands of Tamaulipas, Mexico. I conducted my study at Padre Island National Seashore, to investigate this poorly understood species. I estimated population density and distribution, characterized burrow microhabitat, and used Geographic Information Systems (GIS) to compare transects with different kangaroo rat densities. Live-trapping using mark-recapture methodology was conducted for two periods between April 2010 and October 2010 along 12 transects. A variety of microhabitat characteristics of burrows were measured on active burrows. Trap success for the entire sampling period was 5%, but more individuals were caught during the spring sampling period than the fall sampling period. Using the Lincoln-Peterson index, I estimated a population density of 3.6 individuals per hectare. Active burrows differed significantly in slope, type of vegetative cover, and percent vegetative cover compared to paired random locations. Burrows were found in areas with a higher slope and less vegetative cover. Low trap success and coarse scale ecogeographical layers made development of a habitat suitability model difficult. A more intensive study over a longer time frame will be essential to effectively delineate habitat and predict population sizes--Abstract.

Phillips and published by . This book was released on 2012 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulf Coast kangaroo rat (Dipodomys compactus) is a rarely studied species endemic to southern Texas. Throughout its range, it is intermittently distributed because of its presumed dependence on deep, sandy soils with sparse vegetation. I conducted my study in Guadalupe County, Texas, the northernmost limit of the species' distribution. I collected mark-recapture data during April, July, and September 2011 in order to estimate population density.

This book was released on 2012 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: I conducted a habitat assessment on an inland population of the Gulf Coast kangaroo rat (Dipodomys compactus) located in Guadalupe County, Texas. Previous research on the Padre Island population of the Gulf Coast kangaroo rat has shown the species to inhabit open areas with deep sand and little vegetation, essentially barren sand dunes. However, this distinct habitat type does not occur inland and yet the species is found in certain areas of inland south Texas. The goal of my study was to determine if the northernmost known population of D. compactus retains the species affinity for deep sparsely-vegetated sand habitat. My study site was the Diamond Half Ranch consisting of approximately 2303.3 ha, located 16 km south of Seguin, Texas. In order to assess the habitat associations of this inland Gulf Coast kangaroo rat population, 57 points were semi-randomly located across the study site. At each of these points, I used the Daubenmire frame technique to record the percent of ground cover for grass, forbs, small woody plants, litter (dead herbaceous material), and bare substrate (soil, rock) within a 10 m circle centered on the point. I also recorded the average height of the tallest plants, the average tree canopy present at each point using a spherical densiometer, and the number of active (uncluttered opening, feces, tracks, etc) burrow openings. Data were collected in May 2011, August 2011, November 2011, and February 2012.

This book was released on 2016 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population increases worldwide, urbanization, habitat destruction, and habitat modification also increase. Recently the urbanization rate in Central Texas has become one of the highest in the nation. The consequential loss of natural habitat could jeopardize native wildlife species that are already somewhat limited in their distribution. Based on specialized life-history traits that limit large-scale mobility, kangaroo rats (Dipodomys spp.) have been found to be especially sensitive to urbanization-induced habitat modification and fragmentation. Dipodomys compactus is one of five kangaroo rat species found in Texas; this species has narrow, specific habitat requirements. Using a geographic information system (GIS)-based habitat suitability model, I determined that due to isolation among suitable habitat patches, actual D. compactus range in south-central Texas is highly fragmented, and the particular population in south-central Texas may be more isolated than currently thought. The assessment strategy of GIS habitat mapping can be broadly applied to other vulnerable species with similarly narrow habitat parameters to predict current and future management requirements.
