A concept map for taking biodiversity to school is proposed here using a novel approach that combines systematics, evolutionary biology, and the nature of science. The concept map is tied to the recently published next generation science standards (NGSS). The problem of biodiversity is presented as...
Together, these studies (5–7) initiated a debate on why the average number of species in local communities has not (yet) been negatively affected by the global erosion of biodiversity (5–9, 11). A key lesson learned from this debate is that biodiversity change represents much more than ...
Freshwater Biodiversity The biodiversity of freshwater ecosystems is much more threatened than that of terrestrial ecosystems. More than 10,000 species, or 20% of the world’s freshwater fish, have become extinct, threatened, or endangered in recent decades. Physical alteration, habitat loss, and de...
functional processes can be highly context dependent and difficult to generalize, it is clear that response diversity is an important tool to safeguardtrophic functions. This is a distinction that is important to make not to confuse the message on the importance of biodiversity for ecosystem ...
Several theoretical studies propose that biodiversity buffers ecosystem functioning against environmental fluctuations, but virtually all of these studies ... E Thébault,M Loreau - 《American Naturalist》 被引量: 216发表: 2005年 Diversity without representation Since the 1992 United Nations 'Earth Summit...
In summer they want to go to shallow water so that they can reproduce,” he adds.Mark Heukelum came up with the doorbell idea while working with wildlife ecologist Anne Nijs on a project to highlight the biodiversity in Utrecht’ s canals. At that time they noticed how the lock keeper ...
showing that continued biodiversity loss would result in an accelerating decline in forest productivity worldwide. The value of biodiversity in maintaining commercial forest productivity alone—US$166 billion to 490 billion per year according to our estimation—is more than twice what it would cost to...
They [at EwA] are doing the conservation work that matters – that changes lives – and that people should know more about – they are changing the course of how we understand open spaces and biodiversity in the greater Boston area. –Colleen Hitchcock | Chair, Environmental Studies, Biology ...
Restoring vegetation in degraded ecosystems is an increasingly common practice for promoting biodiversity and ecological function, but successful implementation is hampered by an incomplete understanding of the processes that limit restoration success. By synthesizing terrestrial and aquatic studies globally (25...
The problem, he said, is that many mangrove systems have been converted to shrimp farms, leaving the land vulnerable tostorm surgesand devoid of biodiversity. LIVING PLANET People may think of biodiversity orendangered speciesas something detached from their daily lives. But those people don't und...
