How forest debris affects freshwater food chains
June 11, 2014 12:39 PM - Allison Winter, ENN

While one may think that forest and lake ecosystems are two separate networks, new research shows how forest debris is an important contributor to freshwater food chains. How? Debris in the form of organic carbon from trees washes into freshwater lakes, which consequently supplements the diets of microscopic zooplankton and the fish that feed on them. Researchers at the University of Cambridge conducted a study at Daisy Lake in Ontario, Canadian by observing Yellow Perch fish from different parts of the water body with varying degrees of surrounding forest cover. Carbon from forest debris has a different elemental mass than carbon produced by algae in the aquatic food chain. By analyzing the young Perch that had been born that year, scientists were able to determine that at least 34% of the fish biomass comes from vegetation, increasing to 66% in areas surrounded by rich forest. Essentially, the more forest around the edge of the lake, the fatter the fish in that part of the lake were. Similarly, the sparser the forest leaves, the smaller the fish.

La UNESCO y la Fundación Navegación Oceánica Barcelona unen esfuerzos para la conservación del océano

El viernes pasado en las Naciones Unidas en Nueva York, la Comisión Oceanográfica Intergubernamental de la UNESCO (COI) y la Fundación Navegación Oceánica Barcelona (FNOB) tomaron importantes pasos hacia la conservación del océano mediante la presentación de su compromiso conjunto para la investigación oceanográfica. El anuncio se produjo apenas dos días antes del inicio de la regata transatlántica IMOCA Masters del Océano de Nueva York a Barcelona. Con los miembros de la comunidad de navegantes actuando como agentes del uso sostenible y la protección de los mares y océanos del planeta y el cambio climático como una de las principales prioridades de las organizaciones miembros de las Naciones Unidas para la agenda de 2015-2016, esta asociación representa una alianza sin precedentes entre la vela y las comunidades científicas. La asociación es parte de los esfuerzos de la UNESCO COI para construir una base de conocimientos sobre los océanos y las zonas costeras y aplicar ese conocimiento para mejorar la protección y la gestión sostenible del medio marino y promover comunidades sostenibles.

UNESCO and the Barcelona Foundation for Ocean Sailing Join Forces in Ocean Conservation Effort

Last Friday at the United Nations in New York, the Intergovernmental Oceanographic Commission of UNESCO (IOC) and the Barcelona Foundation for Ocean Sailing (FNOB) took major steps toward Ocean Conservation by presenting their joint commitment for ocean research. The announcement comes just two days before the start of the IMOCA Ocean Masters New York to Barcelona transatlantic sailing race. With members of the sailing community already acting as agents of sustainable use and protection of the world’s seas and oceans and with climate change listed as one of the key priorities of the member organizations of the United Nations for the 2015-16 agenda, this partnership represents an unprecedented alliance between the sailing and scientific communities. The partnership is part of ongoing efforts of UNESCO IOC to build a knowledge base about the oceans and coastal areas and to apply this knowledge to improve the protection and sustainable management of the marine environment and to promote sustainable communities. The formation of this partnership started at the 2011 Barcelona World Race; a two-handed, non-stop around the world race. During the race the teams pledged to collect data in the Southern Ocean, an area for which data is still lacking. The region is considered key in monitoring climate change.
