“…was chosen as a food item for Lytechinus for several reasons: (1) Ulva sp. are one of the most abundant macroalgal species, along with turf, crustose coralline algae, and Sargassum , in the Galápagos nearshore habitats (Vinueza et al, 2006; Vinueza, 2009); (2) ephemeral species, like Ulva , are highly palatable for herbivores (Carpenter, 1986); and (3) sea urchin fronts in the Galápagos appear to consume all macroalgal species except for brown species (e.g., Padina ) (L. Carr personal observation ) and damselfish turfs (Irving & Witman, 2009). …”

Warming increases the top-down effects and metabolism of a subtidal herbivore

Ecological theory and experiments indicate that warming can increase the relative strength of top-down effects via alterations to metabolic rates in several different systems, thereby resulting in decreased plant biomass at higher temperatures. However, the general influence of increased environmental temperature on top-down effects is not well understood in systems where organisms experience relatively large variation in temperature. Rapid ocean temperature changes are pervasive throughout the Galápagos Islands due to upwelling and downwelling of internal waves, ENSO events and seasonality. We measured the effect of large, but not uncommon, water temperature variation on the metabolism and grazing rate of a common subtidal herbivore and on photosynthesis of their algal prey in the Galápagos Islands in July 2012. We found that green urchin consumption and metabolism were greater at the higher temperature treatment (28°C), resulting in significantly less algal biomass. Our result that warming increased green urchin metabolic rates, even in a highly dynamic system, provides further support for a mechanistic link between environmental temperature and feeding rates. And further, our findings suggest individual response to temperature results in changes in top-down effects. And if this response is maintained over longer-time scales of days to weeks, this could translate to alterations of larger-scale ecological patterns, such as primary producer community composition and structure.

“…Southern Australia, including Tasmania (Fulton et al, 2014) and the Galápagos Islands (Castrejón and Charles, 2013;Vinueza et al, 2014) may be considered two of the first well-documented examples of the EAF in practice globally. These initiatives have been using a wide range of ecological, economic and social indicators, in contrast to the 8-fjords initiative, which only has some indicators and thereby a limited monitoring.…”

“…Indicators that describe other important aspects of ecosystem structure and function, such as water transparency, nutrient and toxin loads and concentrations (Håkanson and Blenckner, 2008;Fleming-Lehtinen et al, 2015;Lang et al, 2015), are available to some extent. Economic and social indicators are wanted while being of comparable importance as ecological ones (Leslie and McLeod, 2007;Fulton et al, 2014;Vinueza et al, 2014). It is possible that relevant economic and social indicators are already extractable from statistics collected by the municipalities surrounding the fjords, and merit further investigations.…”

“…Ideally, there should be ecological, economic and social indicators (Leslie and McLeod, 2007). Examples of ecological indicators are the proportion of habitat coverage, the biomass of fish species (Fulton et al, 2014), the number of species, the species composition in the ecosystem (Vinueza et al, 2014), the mean length of species and their slope size spectrum (Link, 2005). For discussions on optimal quantitative indicators for the impact of fisheries on ecosystems, see e. g. Link (2005) and Methratta and Link (2006).…”

. (2017) AbstractThe coastal marine environment in the 8-fjords area on the Swedish west coast has been subjected to various stakeholder co-management initiatives since 1999. Stakeholders and authorities have acted by supporting and implementing gradually stricter fishing restrictions following the collapse in the 1970s of several demersal fish stocks and their apparent lack of recovery. Moreover, concerns have been raised regarding a locally sharp depletion of eelgrass meadows, in addition to an apparent increase in the number of seals and cormorants. The present 8-fjords

The Galápagos archipelago: a natural laboratory to examine sharp hydroclimatic, geologic and anthropogenic gradients

et al. 2016

Poor understanding of the water cycle in tropical ecosystems has the potential to exacerbate water shortages and water crises in the region. We suggest that the Galápagos Islands provide an excellent proxy to regions across the tropics as a result of sharp hydroclimatic, anthropogenic, and pedohydrologic gradients across the archipelago. Hydroclimatic and pedohydrologic gradients are found across different elevations on single islands, as well as across the archipelago, whereas anthropogenic gradients reflect land use and land cover change across islands as population and growth in tourism have affected individual islands differently. This article highlights specific opportunities to further examine our understanding of the interactions between water and critical zone processes in tropical ecosystems, making connections between the Galápagos archipelago and much of the understudied tropics. The Galápagos archipelago offers a natural laboratory through which we can examine current threats to freshwater security as well as the dynamics of coupled natural and human systems.
