| Somatic embryogenesis system to propagate pine hybrids able to tolerate water stress Posted: 11 Jun 2014 07:21 AM PDT The high water stress tolerance of hybrids of the Radiata Pine (Pinus radiata X Pinus attenuata) has been under study by researchers, who note that these trees appear to be a very interesting alternative for the forestry sector in view of the modifications ecosystems are undergoing and will be undergoing as a result of climate change. |
| Colonial-era dams trigger parallel evolution of Connecticut fish Posted: 10 Jun 2014 05:53 PM PDT Decisions made by Colonial era settlers to dam Connecticut waterways triggered sudden and parallel evolutionary changes in two species of fish competing for food, a new study shows. Earlier studies documented the decrease in size and changes in gill structure of members of the alewife species cut off from access to the sea in newly dammed lakes. The new study found similar changes in feeding habits of the bluegill, which also showed greater ability to feed on smaller zooplankton found in landlocked lakes the species shared with the alewife. |
| Coho salmon: Pinks' and chums' eating cousin Posted: 10 Jun 2014 11:47 AM PDT Juvenile coho salmon benefit from dining on the distant remains of their spawning pink and chum cousins. While juvenile coho salmon feed directly on spawning pink and chum salmon carcasses and eggs, even coho with no direct contact with spawning pink and chum benefit from their nutrient contributions to stream ecosystems. |
| New formula assigns dollar value to natural resources Posted: 10 Jun 2014 11:43 AM PDT A first-of-its-kind, interdisciplinary equation to measure the monetary value of natural resources has been developed by researchers. The equation uses principles commonly used to value other capital assets. In assigning natural capital monetary value, the approach will have widespread implications for policymakers and various stakeholders, and will also advocate for the creation of robust asset markets for natural capital, a much-needed advance. |
