Download or read book Texans on the Brink written by Brian R. Chapman and published by Texas A&M University Press. This book was released on 2019-03-27 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: What good is a rattlesnake? What purpose do animals serve? All species play a vital role in their biological communities, and the removal of just one can have a noticeable and catastrophic ripple effect. Yet social and political pressures frequently pit species conservation against economic progress and prosperity, and scientists fear that we may be in the midst of a mass extinction event. Brian R. Chapman and William I. Lutterschmidt make the case that the effort to preserve animals is the responsibility of every Texan and that biodiversity contributes enormous economic value to the citizens of Texas. Texans on the Brink brings together experts on eighty-eight endangered and threatened animal species of Texas and includes brief descriptions of the processes that state and federal agencies employ to list and protect designated species. Species accounts include a description of the species accompanied by a photograph, an easy-to-read account of the biology and ecology of the species, and a description of efforts underway to preserve the species and its required habitat. Sobering examples of species that were once part of the Texas fauna but are now extinct or extirpated are also given to further demonstrate just how vulnerable biodiversity can be. All species require healthy habitats, and every species—even a rattlesnake—provides important services for the biotic communities in which they live. It is imperative to learn as much as we can about these animals if we are to preserve biodiversity successfully in Texas.
Download or read book Systematics conservation and morphology of the spider genus Tayshaneta Araneae Leptonetidae in Central Texas Caves written by Joel Ledford and published by PenSoft Publishers LTD. This book was released on 2012-01-23 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spider genus Tayshaneta is revised based on results from a three gene phylogenetic analysis (Ledford et al. 2011) and a comprehensive morphological survey using scanning electron (SEM) and compound light micros-copy. The morphology and relationships within Tayshaneta are discussed and five species-groups are supported by phylogenetic analyses: the anopica group, the coeca group, the myopica group, the microps group and the sandersi group. Short branch lengths within Tayshaneta contrast sharply with the remaining North American genera and are viewed as evidence for a relatively recent radiation of species. Variation in troglomorphic morphology is discussed and compared to patterns found in other Texas cave invertebrates. Several species previously known as single cave endemics have wider ranges than expected, suggesting that some caves are not isolated habitats but instead form part of interconnected karst networks. Distribution maps are compared with karst faunal regions (KFR?s) in Central Texas and the implications for the conservation and recovery of Tayshaneta species are discussed. Ten new species are described: T. archambaulti sp. n., T. emeraldae sp. n., T. fawcetti sp. n., T. grubbsi sp. n., T. madla sp. n., T. oconnorae sp. n., T. sandersi sp. n., T. sprousei sp. n., T. vidrio sp. n. and T. whitei sp. n. The males for three species, T. anopica (Gertsch, 1974), T. devia (Gertsch, 1974) and T. microps (Gertsch, 1974) are described for the first time. Tayshaneta furtiva (Gertsch, 1974) and T. uvaldea (Gertsch, 1974) are declared nomina dubia as the female holotypes are not diagnosable and efforts to locate specimens at the type localities were unsuccessful. All Tayshaneta species are thoroughly illustrated, diagnosed and keyed. Distribution maps are also provided highlighting areas of taxonomic ambiguity in need of additional sampling.
