Geographic isolation, gene flow and population differentiation in Goodea atripinnis (Pisces: Goodeidae)An allozyme survey of thirty-four loci from seventeen populations of the goodeid fish Goodea atripinnis was conducted to examine the extent of differentiation between continuous and isolated populations...
Lower awareness of COVID-19 may result in less attention paid to personal mitigation techniques and lower compliance with non-pharmaceutical interventions5, which together may put deprived populations at greater risk of contracting COVID-19. Due to the lower incidence and mortality of COVID-19 in...
However, in recent years, the predictive applicability of pollination syndromes has been frequently questioned. The accuracy of the syndromes among the closely related plant species may vary temporally and spatially. This suggests the need for the standardized, comprehensive evaluation of factors ...
Overall, our results indicate that geographic isolation, and potentially other factors such as shallow water habitats to rest and socialise, may be important drivers of the genetic population structure of insular spinner dolphins in this region. 展开 ...
Genetic isolation and divergence in sexual traits: evidence for the northern rockhopper penguin Eudyptes moseleyi being a sibling species The taxonomic status of populations of rockhopper penguins ( Eudyptes chrysocome ) is still enigmatic. Northern populations differ from southern ones in br... P Jouv...
However, the mean pairwise Fst is more than doubled to 0.055 when genotypes are instead partitioned by region of isolation, indicating moderate genetic differentiation. Together, this suggests geographic origin accounts for a greater portion of signal for population differentiation than variety in ...
is always similar to the fauna of the nearest continent. It differs mainly in the absence of certain species (the so-called rule of island impoverishment) and a greater number of endemic species, which is the result of speciation during geographical isolation. In general, the farther an island...
Geographical isolation, combined with a reduction in habitat range and small population size, is expected to cause a decline in a population [9,10]. This can form a barrier to gene flow that can result in an increased impact of genetic drift, rising inbreeding rates, local adaptation and ...
根据最后一段中At a party with colleagues,I was going on about everything I couldn't stand in our town when I noticed that they were silent and shifting uncomfortably.That moment forced a change in me.Complaining may offer relief,but so does acceptance.There is no perfect...
Isolation by distance exists across the archipelago with limited influence of fragmentation by brackish seawater. The extremely low genetic diversity in all-hybrid populations, compared with adjacent populations, may be responsible for the maintenance of their special breeding system. We also show large ...
