*** Marine Biodiversity and Ecosystem Function in a Warming Ocean ***
\nMarine biodiversity is dynamic; species\u2019 abundance and distribution are shifting
\nwith climate, human-facilitated transport, disturbance, and natural causes.
\nDespite concern globally for biodiversity loss, recent analyses have
\nsuggested that locally species richness is relatively stable despite changes
\nin species composition. The future in marine ecosystems will reflect both
\nchanges in species biodiversity, as well as how the constraints on
\nbiodiversity and its functional consequences change with changing climate.
\nHere, I consider the implications of current trends in marine biodiversity
\nfor marine ecosystems given projections of ocean warming using climate
\nvelocity metrics. Trends in biodiversity will occur within the context of
\nmarine ecosystem function, which reflects the fundamental constraints of
\ntemperature on the biomass and energy flow of food webs. Experimental work
\nin aquatic food webs suggests that functional responses to climate change
\nwill reflect constraints independent of shifts in biodiversity. A major
\nchallenge is to identify ecosystem change that constrains biodiversity
\nchange, and the feedbacks then between biodiversity and ecosystem function.<\/p>\n
*** Kelp Forests in the Era of Climate Change ***
\nKelps have the potential to dominate roughly one quarter of the world\u2019s coastlines. These temperate-water large brown algae provide a wide variety of key ecosystem
\nservices. They provide habitat and food for many fish and invertebrate
\nspecies. They are harvested themselves for food and chemicals.
\nTheir structure can alter coastal hydrodynamics. Changes in kelp populations
\ncan have large effects cascading through an ecosystem. We know that kelps
\nhave the potential to be susceptible to climate change driven shifts in the
\nocean environment. Here I discuss recent models and meta-analyses examining
\nour current knowledge about the future of kelp forest ecosystems. I show
\nthat models of kelp forest interaction webs incorporating climate drivers
\nsuggest kelp declines in many systems around the globe. I present evidence
\nfrom a meta-analysis of extant time-series demonstrating that some regions
\nare already experiencing kelp declines, but that this pattern is not
\nuniform. Using meta-analysis of kelp removal experiments, I show that kelp
\nlosses have potentially very different effects on fish at different trophic
\nlevels. I close with possibilities for future research, both from the
\nscientific community and citizen scientists, to help us better understand
\nhow kelp forests across the globe might shift in the era of climate change.<\/p>\n","protected":false},"excerpt":{"rendered":"
