Theoretical framework Evolutionary rescue

-


the theoretical characterization of evolutionary rescue may u-shaped curve.


it may easier find quantifiable evidence evolutionary rescue in rapidly shifting environments versus gradually shifting environments (climate change, ocean acidification, etc). high localization , source-sink biogeographic demographic dynamics may increase likelihood of evolutionary rescue. evolutionary rescue may highly characterized u-shaped curve, in population declines sharply until passes stochastic threshold, @ adaptive allele frequency rapidly increases, population rebounding @ slower rate well. vulnerable part of evolutionary rescue process, theoretically, should time point during population beyond stochastic threshold, exposes population random outcomes not determined genetic or evolutionary mechanisms.

Deep sea mining Marine pollution

deep sea mining relatively new mineral retrieval process takes place on ocean floor. ocean mining sites around large areas of polymetallic nodules or active , extinct hydrothermal vents @ 1,400 – 3,700 meters below ocean s surface. vents create sulfide deposits, contain precious metals such silver, gold, copper, manganese, cobalt, , zinc. deposits mined using either hydraulic pumps or bucket systems take ore surface processed. mining operations, deep sea mining raises questions environmental damages surrounding areas because deep sea mining relatively new field, complete consequences of full-scale mining operations unknown. however, experts removal of parts of sea floor result in disturbances benthic layer, increased toxicity of water column, , sediment plumes tailings. removing parts of sea floor disturbs habitat of benthic organisms, possibly, depending on type of mining , location, causing permanent disturbances. aside direct impact of mining area, leakage, spills, , corrosion alter...
