Opportunistic exploitation: an overlooked pathway to extinction.
Trends Ecol Evol. 2013 Apr 4;
Authors: Branch TA, Lobo AS, Purcell SW
How can species be exploited economically to extinction? Past single-species hypotheses examining the economic plausibility of exploiting rare species have argued that the escalating value of rarity allows extinction to be profitable. We describe an alternative pathway toward extinction in multispecies exploitation systems, termed ‘opportunistic exploitation’.
Riding the crimson tide: mobile terrestrial consumers track phenological variation in spawning of an anadromous fish.

When resources are spatially and temporally variable, consumers can increase their foraging success by moving to track ephemeral feeding opportunities as these shift across the landscape; the best examples derive from herbivore-plant systems, where grazers migrate to capitalize on the seasonal waves of vegetation growth.

Research on food webs increasingly relies on sampling biomarkers (stable isotopes and fatty acids) in consumers and their potential prey. In studies of macroalgal and seagrass biomarkers in the northeast Pacific, Dethier and coworkers found substantial variation in biomarkers across dates and sites.

Branch TA, Hively DJ, Hilborn R (2013) Is the ocean food provision index biased? Nature 495:E5-E6
How close to maximum sustainable food provision is current seafood harvest from the world’s oceans? Halpern et al.  suggest that the answer is 25% from a global index of food provision, part of their multifaceted index of ocean health. Rigorous methods used for management, however, demonstrate that their food provision index is uncorrelated with actual food provision, and that global ocean food provision is in the range of 71–95%.
