Workshop on Protection of Endangered Birds

DAMASCUS, (ST) -The Minister of State for Environmental Affairs Dr. Nazira Sarkis underlined that the government had given marsh Jabboul a great importance to the great richness in biodiversity and its importance as a world site exposed to many different threats.

Dr. Sarkis, during a workshop to protect endangered birds in the marsh Jabboul, explained that the project aims to improve the status of protection for endangered species of birds and biodiversity conservation in the marsh Jabboul through the promotion of fishing laws and spreading awareness among locals and fishermen to preserve the birds and their habitats. The workshop carried out by the Ministry of State for Environmental Affairs and the Syrian Society for the Protection of Wildlife in cooperation with the Small Grants Program (SGP).

Geologists confirm oxygen levels of ancient oceans

Geologists in the College of Arts and Sciences have discovered a new way to study oxygen levels in Earth's oldest oceans.

Zunli Lu and Xiaoli Zhou, an assistant professor and Ph.D. student, respectively, in the Department of Earth Sciences, are part of an international team of researchers whose findings have been published by the journal Geology (Geological Society of America, 2014). Their research approach may have important implications for the study of marine ecology and global warming.

Astronomers discover two new worlds orbiting ancient star next door

An international team of astronomers, including five Carnegie scientists, reports the discovery of two new planets orbiting a very old star that is near to our own Sun. One of these planets orbits the star at the right distance to allow liquid water to exist on its surface, a key ingredient to support life.

Water goes 'missing' with snow loss

 A new study finds that if temperatures rise and more precipitation falls as rain rather than snow, it will reduce the total amount of water in rivers.

It is a surprising observation. One might expect the timing of water flow to change but not the overall volume.

The researchers report their work in the journal Nature Climate Change.

Environmental conditions may impact bird migration

Wind conditions during spring migration may be a predictor of apparent annual survival and the timing of breeding in yellow warblers, according to results published May 14, 2014, in the open access journal PLOS ONE by Anna Drake from Simon Fraser University, Canada and colleagues.

Migratory birds play a critical role in the ecosystem, pollinating plants, dispersing seeds, and consuming insects and small mammals. Yellow warblers breed in western Canada and overwinter in Mexico, making them difficult to study during all stages of their annual cycle. Scientists used data collected from 380 birds over seven breeding seasons to examine how climatic conditions during the winter migratory and breeding season influenced survival and reproduction. They found that of the climatic models tested, wind speeds on migration best predicted apparent annual adult survival, male arrival date at the breeding site, female egg laying, and annual productivity.
