Book Description

Lakeside Recreation is the most complete and up-to-date book available on the lakes constructed by the US Army Corps of Engineers. The book describes nearly 150 lakes and reservoirs in the western United States. Surrounding the lakes are more than 1,200 recreation areas, including more than 800 campgrounds and over 35,000 campsites. Detailed descriptions in Lakeside Recreation include maps of each lake that show the location of all campgrounds and recreation areas. Facilities such as restrooms, showers, dump stations, swimming beaches, trails, and picnic areas are also covered in the 280-page book. Anglers will find information about the types of fish in each lake and the location of boat ramps, fishing piers, and marinas. Lakeside Recreation includes projects in: Alaska, Arizona, California, Colorado, Idaho, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, and Washington. ...

Book Description

One hundred years ago, Chesapeake Bay swarmed with one thousand unique vessels. They were called Skipjacks, powered by the wind and used to harvest as many as ten million oysters in a single season. The harvest today has fallen to less than one-tenth of that. And the Skipjack is almost extinct, with no more than ten still used in dredging for oysters.

The history of the Skipjacks, the men who sailed them, and the Chesapeake oyster industry are documented in thislarge 142-page coffee table book with more than 170 color and many black-and-white photographs, perhaps the largest private collection of Skipjack photos in existence. ... Read more

Book Description

Several cyanobacterial species can produce powerful toxins that provide a serious threat for water quality, other aquatic organisms, and human health. These harmful cyanobacteria are especially prominent in freshwater ecosystems, and are a major concern for water managers.

From a scientific perspective, there are many recent advances in this research area:
- Owing to the scientific revolution in genomics, new molecular techniques have been developed that enable the detection of toxic cyanobacteria at a very early stage.
- New laboratory culture techniques have enabled eco-physiological studies of toxin production at a detailed scale that was beyond reach until recently.
- Remote sensing of freshwater cyanobacteria is a rapidly expanding field, owing to the increased spectral resolution of airborne data.
- New computational techniques have led to advanced models on the population dynamics of cyanobacteria.

From a management perspective, recognition of the toxins produced by harmful cyanobacteria has recently led to new environmental policies with respect to toxic cyanobacteria in many western countries.

The purpose of this work is to provide an up-to-date overview of the advances in our knowledge of harmful cyanobacteria. The work is directed towards graduate students and scientists in aquatic microbiology, aquatic ecology, environmental toxicology, and water management, and academic professionals in water management and environmental policy.

"This is an outstanding volume that should be a 'must-see' reference for all scientists and environmental professionals who are interested in cyanobacterial ecology and water quality management." Val H. Smith, University of Kansas, USA

 

Book Description

Twelve months of visits to a mountain lake tells more than twelve tales. The solitude found during a Wednesday in the winter is completely different than the chaos found on a Saturday in the summer. The seasons make one set of changes. We make the other. The combination produces a much more interesting set of experiences that can't be revealed in one visit or in a page of some guidebook.

(Spanish)Un muy buen libro de genetica para acuicultores
REVIEW IN SPANISH

Este es un excelente libro introductorio para la genética de peces, especialmente para acuaristas, acuicultores y biólogos marínos. En general presenta un ingles simple que permite que sea leído por casi cualquier público que domine algunos terminos técnicos, característica que será muy apreciada por los lectores de habla hispana. El autor hace una muy buena división de la genética en fenotipos cualitativos y cuantitativos la cual resulta muy didáctica.

La genética mendeliana (fenotipos cualitativos) está tratada con exelente claridad enfocando todos los topicos (principios mendelianos, epistasis, penetrancia, expresividad, pleiotropía, etc) con ejemplos de peces, principalmente peces ornamentales (se las recomiendo a los acuaristas que deseen saber más acerca del control genético de los rasgos de sus peces ornamentales de interes).

La genética cuantitativa (fenotipos cuantitativos) es de las más simples y lúcidas explicaciones que he leido. Este tópico esta dividido en explotación de la varianza aditiva por selección y en la explotación de la varianza de dominancia por hibridizacíon. Aqui el autor expone parte de su experiencia en programas selectivos con tilapia. Finalmente el libro trae un pequeño capítulo introductorio a la biotecnologia, corto pero preciso. Aquí se exponen temas como inducción de triploides, gimnogenesis y androgenesis, ADN recombinante, etc.

El libro además de incluir un glosario de términos técnicos que facilita la lectura a las personas no especilistas en el tema, incluye además un anexo con estadistica básica y uno de nombres científicos y comunes de los peces mencionados en el texto, muy útil para los lectores.

En resumen un excelente libro introductorio para quienes le interese la genética en la cria y producción de peces. CRISTIAN ARANEDA T. ICBM - Programa de Genética Humana Facultad de Medicina Universidad de Chile Casilla 70061 Correo 7 - Santiago de Chile ... Read more
