Study: Temperature influences bird diversity loss in Mexico
July 7, 2015 02:22 PM - The University of Kansas

A wide-ranging study of gains and losses of populations of bird species across Mexico in the 20th century shows shifts in temperature due to global climate change are the primary environmental influence on the distributions of bird species. “Of all drivers examined … only temperature change had significant impacts on avifaunal turnover; neither precipitation change nor human impacts on landscapes had significant effects,” wrote the authors of the study, which appeared recently in the peer-reviewed journal Science Advances. Using analytical techniques from the field of biodiversity informatics, researchers compared current distributions with distributions in the middle 20th century for 115 bird species that are found only in Mexico. They then compared those bird community changes to patterns of change in climate and land use.

Característica de las plantas ayuda a conservar el agua potable
July 7, 2015 07:50 AM - American Society of Agronomy.

Las plantas necesitan agua. La gente necesita agua. Por desgracia, sólo hay una cantidad limitada de agua limpia para todos, por lo que se inicia el esfuerzo para encontrar una solución.

Por suerte para las personas, algunas plantas son capaces de arreglárselas sin agua que sea perfectamente limpia, por lo que nos queda más agua buena para beber. Una de las estrategias es utilizar agua residual tratada, que contiene restos de sal de los procesos de limpieza, para regar grandes extensiones de césped. Estas áreas incluyen campos deportivos y campos de golf. Sólo los campos de golf utilizan aproximadamente 750 mil millones de galones de agua al año en las regiones áridas.

Sin embargo, la mayoría de las plantas no pueden tolerar una gran cantidad de sal. Conforme algunas áreas de los Estados Unidos se están quedando sin agua limpia, los criadores de plantas están tratando de obtener plantas que sean más tolerantes a la sal. Esto significa conservar agua limpia, manteniendo el césped saludable.

Se puede ver realmente el efecto individual de lo que cada planta madre hereda a su descendencia porque los genes añaden intensidad a este rasgo o característica. Estos son efectos aditivos. Los criadores pueden seleccionar más fácilmente esas características cuando observan esas diferencias.

Breeders select trait to conserve drinkable water

Plants need water. People need water. Unfortunately, there’s only so much clean water to go around — and so the effort begins to find a solution.

Luckily for people, some plants are able to make do without perfectly clean water, leaving more good water for drinking. One strategy is to use treated wastewater, containing salt leftover from the cleaning process, to water large areas of turf grass. These areas include athletic fields and golf courses. Golf courses alone use approximately 750 billion gallons of water annually in arid regions.

However, most plants cannot tolerate a lot of salt. As some areas of the United States run low on clean water, plant breeders are trying to breed plants that are more salt tolerant. This would conserve clean water while maintaining healthy turf.

Plant breeders can actually see the individual effect of what each parent plant passes on because the genes add intensity to the trait. These are additive effects. Breeders can more easily select for those features when they observe those differences.
