Climate change and dispersal

DISPERSAL EVOLVE UNDER CLIMATE CHANGE Instructor: Mai Anh Khoa Member of group : Nguyễn Thị Phương Nguyễn Hải Nam Ngô Thị Thanh Quế Nông Thị Hương Thơ Lê Đức Trung Đào Thị Phương Thanh OUTLINE I Introduction II The effects of climate change to the dispersion III The way dispersion evolve under climate change IV Conclusion II The effects of climate change to the dispersion • • • •• • • Decrease flight probability in moths butterflies and sparrows dispersal likelihood Increase piping plovers Decrease butterfly flight time move length & Reduce takeoff of ballooning spiders Increase fish movement between rivers Increase advanced departure uplift of wind dispersal seeds of seal pups Reduce distance of wind dispersal seeds • Decrease dispersal4.probability of spiders & lizards afternoon optimal temperatures • Decrease departure of smaller individuals • Decrease asynchrony with ant dispersal of Increase distances shift in spider dispersal modes Decrease departure smaller individuals •• Decrease ofofsmaller individuals Increase seeds dispersal probability of water birds Increase seed distances from taller plants • Decrease distances of smaller individuals • Increase songbird distances • Decrease distances of fast developing plankton III The way dispersion evolve under climate change Increased emigration rates, even when local populations are at low densities Promote risky movement behaviours, enhancing the possibility of long distance dispersal even if mortality is increased Foster investment in dispersal traits at the expense of other life-history attributes Stationary ranges, including kin competition and inbreeding depression III The way dispersion evolve under climate change In context of Vietnam: Plants Bloom earlier Insects Appeared earlier than in the northern hemisphere • Birds Migration season Animal earlier shifted Fish has started Breeding earlier in the season Northward Tropical fish increased Subtropical fish species decrease to • Higher ground IV Conclusion Climate change has many effects on the evolution of dispersal in many aspect and individuals also have responses to this change However, interventions seem essential to avoid species extinctions under climate change Reference Anderson B J et al 2009 Dynamics of range margins for metapopulations under climate change Proc R Soc B 276:1415– 1420 Balanyá J et al 2006 Global genetic change tracks global climate warming in Drosophila subobscura Science 313:1773– 1775 Bartoń K A et al 2012 Risky movement increases the rate of range expansion Proc R Soc B 279: 1194–1202 Battisti A et al 2006 A rapid altitudinal range expansion in the pine processionary moth produced by the 2003 climatic anomaly Global Change Biol 12: 662–671 Bell G and Gonzalez A 2011 Adaptation and evolutionary rescue in metapopulations experiencing environmental deterioration Science 332: 1327–1330 Berg M P et al 2010 Adapt or disperse: understanding species persistence in a changing world Global Change Biol.16: 587– 598 Minh P.B et al 2009 Biến đổi khí hậu ảnh hưởng biến đổi khí hậu Nong Lam university [...]...Reference 1 Anderson B J et al 2009 Dynamics of range margins for metapopulations under climate change Proc R Soc B 276:1415– 1420 2 Balanyá J et al 2006 Global genetic change tracks global climate warming in Drosophila subobscura Science 313:1773– 1775 3 4 Bartoń K A et al 2012 Risky movement increases... processionary moth produced by the 2003 climatic anomaly Global Change Biol 12: 662–671 5 Bell G and Gonzalez A 2011 Adaptation and evolutionary rescue in metapopulations experiencing environmental deterioration Science 332: 1327–1330 6 Berg M P et al 2010 Adapt or disperse: understanding species persistence in a changing world Global Change Biol.16: 587– 598 7 Minh P.B et al 2009 Biến đổi khí hậu
