Este libro es el producto del trabajo colegiado que han desarrollado los profesores, investigadores, y estudiantes que conforman la Red Temática de Calidad Ambiental y Desarrollo Sustentable, a través del macroproyecto “Evaluación del impacto ambiental por actividades antropogénicas: Alternativas de mitigación”. El cual fue apoyado con recursos financieros por parte del Programa para el Desarrollo Profesional Docente (PRODEP), de la Secretaria de Educación Pública (SEP) en México. Las instituciones de educación superior y cuerpos participantes en la red temática son la Universidad Autónoma del Estado de Hidalgo (Uso, Manejo y Conservación de la Biodiversidad UAEHCA- 10; Ciencias Ambientales UAEH-CA-59); Universidad …

Introduced species of amphibians and reptiles are of growing conservation concern (Bury and Luckenbach 1976; Krysko et al. 2011; Meshaka 2011). Unintentional introductions result largely from individuals escaping from enclosures or hitch-hiking in cargo or on vehicles, whereas intentional introductions occur primarily because a species is perceived to be of value to humans or from deliberately releasing sick or unwanted animals, including pets (Kraus 2009; Krysko et al. 2011). In Florida, most known introductions are directly related to the pet trade, but about 12% are related to the cargo pathway (Krysko et al. 2011). In this paper, we report the …

Mammalian distributions are constantly changing. Some distributional shifts reflect habitat change, climate change, and human transplantations; thus, such shifts are due to actual expansions or contractions of populations. However, other species ranges that appear to shift as the result of new records being added to known distributional limits actually might reflect populations that previously were undetected due to a lack of past surveys or species that are difficult to detect. In 2013, multiple techniques were employed to document mammalian distributional records in southwestern Kansas and northwestern Oklahoma. We discovered three new county records in Morton County, Kansas (Crawford’s Desert Shrew, …
Ecology And Management Of Superabundant Fish Populations, Nathaniel T. Stewart
Ecology And Management Of Superabundant Fish Populations, Nathaniel T. Stewart
School of Natural Resources: Dissertations, Theses, and Student Research
Fish population biomasses can reach extreme levels; we term these populations superabundant fish populations. Superabundant fish populations may negatively affect aquatic communities and anglers, necessitating the effective management of the superabundant fish populations. However, there are gaps in our understanding of these populations. The gaps in our understanding hamper our ability to predict effects on valuable sportfisheries and to effectively manage superabundant fish populations. The overall goal of my thesis research is to provide further insight into the ecology of superabundant fish populations and to provide information that will aid in their effective management. First, we described a new method …
Genetic And Morphological Variation In Ecuadorian Astroblepid Catfishes, Katherine M. Lawry
Genetic And Morphological Variation In Ecuadorian Astroblepid Catfishes, Katherine M. Lawry
School of Natural Resources: Dissertations, Theses, and Student Research
The Andean ichthyofauna remains a poorly understood component of Neotropical biodiversity, and stands in stark contrast to the lowland ichthyofauna in terms of number of species and range of distribution. The Climate Variability Hypothesis (CVH) predicts rapid turnover of species along elevational gradients in tropical climates, but it remains unclear whether stream fishes follow this pattern. Astroblepid catfishes represent a distinctive assemblage of species that inhabit high elevation streams throughout the Andes from Panama to Bolivia, and constitute the only native fish family present in the Ecuadorian highland region. In this research, population samples of Astroblepids collected throughout Ecuador’s Napo …
Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard
Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard
Zea E-Books Collection
Based on an analysis of 47 years (1967–2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root’s 1988 Atlas of North American Wintering Birds. Root’s landmark study provided a baseline for evaluating the nationwide winter distributions of 253 North American birds in the mid-20th century, using data from the National Audubon Society’s …
