Birds are islands for parasites.
Understanding the mechanisms driving the extraordinary diversification of parasites is a major challenge in evolutionary biology. Co-speciation, one proposed mechanism that could contribute to this diversity is hypothesized to result from allopatric co-divergence of host-parasite populations. We found that island populations of the Galápagos hawk (Buteo galapagoensis) and a parasitic feather lo...
متن کاملAre parasites “prudent” in space?
There has been a renewed controversy on the processes that determine evolution in spatially structured populations. Recent theoretical and empirical studies have suggested that parasites should be expected to be more ''prudent'' (less harmful and slower transmitting) when infection occurs locally. Using a novel approach based on spatial moment equations, we show that the evolution of parasites ...
متن کاملDigestive tract parasites in rhynchoteuthion squid paralarvae, particularly in Illex argentinus (Cephalopoda: Ommastrephidae)
Cephalopods play an important role in the transfer of parasites through the food web. They are second and third intermediate hosts for larval stages of digeneans, cestodes, and nematodes. The final hosts are usually fishes, sea birds, and marine mammals (Hochberg, 1990). Nevertheless, the interactions of cephalopods and their parasites are still poorly understood, and almost nothing is know abo...
متن کاملPds Watches : How Dangerous Are These “ Particularly Dangerous Situations ? ”
Such watches are known as “PDS” watches. PDS tornado (TOR) watches are issued when the forecaster has high confidence that multiple strong (F2-F3 on the Fujita Scale) or violent tornadoes (F4-F5 on the Fujita Scale) will occur in the watch area, while PDS severe thunderstorm (SEV) watches are issued when there is a threat of a high end “derecho” (e.g. Johns and Hirt 1987, Coniglio et al. 2004) ...
متن کاملAre unequal clade priors problematic for Bayesian phylogenetics?
Although Bayesian phylogenetic methodologies were first developed in the 1960s (Felsenstein, 1968, 2004), the approach remained relatively obscure until the initial release of the software application MrBayes (Huelsenbeck and Ronquist, 2001). Since that time, the popularity of Bayesian phylogenetics has increased tremendously, and it now must be considered a primary method of analysis on par wi...
