@article{fdi:010046348, title = {{H}ost-parasite determinants of parasite population structure : lessons from bats and mites on the importance of time}, author = {{M}c{C}oy, {K}aren}, editor = {}, language = {{ENG}}, abstract = {{B}y definition, parasitic organisms are strongly dependant on their hosts, and for a great majority, this dependence includes host-to-host transmission. {C}onstraints imposed by the host's spatial distribution and demography, in combination with those of the parasite, can lead to a metapopulation structure, where parasite populations are highly stochastic (i.e. prone to frequent extinctions and re-colonizations) and where drift becomes a major force shaping standing genetic variation. {T}his, in turn, will directly affect the observed population structure, along with the ability of the parasite to adapt (or co-adapt) to its host. {H}owever, only a specific consideration of temporal dynamics can reveal the extent to which drift shapes parasite population structure; this is rarely taken into account in population genetic studies of parasitic organisms. {T}he study by {B}ruyndonckx et al. in this issue of {M}olecular {E}cology does just this and, in doing so, illustrates how a comparison of host-parasite co-structures in light of temporal dynamics can be particularly informative for understanding the ecological and evolutionary constraints imposed by the host. {M}ore specifically, the authors examine spatial and temporal population genetic data of a parasitic mite {S}pinturnix bechsteini that exclusively exploits the {B}echstein's bat {M}yotis bechsteinii and consider these data in relation to host-parasite life histories and the population structure of the host.}, keywords = {co-evolution ; drift ; ectoparasite ; {M}yotis bechsteinii ; population dynamics ; social behaviour ; {S}pinturnix bechsteini}, booktitle = {}, journal = {{M}olecular {E}cology}, volume = {18}, numero = {17}, pages = {3545--3547}, ISSN = {0962-1083}, year = {2009}, DOI = {10.1111/j.1365-294{X}.2009.04300.x}, URL = {https://www.documentation.ird.fr/hor/fdi:010046348}, }
