Data from: Habitat fragmentation alters the properties of a host-parasite network: rodents and their helminths in South-East AsiaFrédéric Bordes, Serge Morand, Shai Pilosof, Julien Claude, Jean-François Cosson, Yannick Chaval, Alexis Ribas, Kittipong Chaisiri, Kim Blasdell, Annelise Tran, Stéphane Dupuy & Boris R. Krasnov
1. While the effects of deforestation and habitat fragmentation on parasite prevalence or richness are well investigated, host–parasite networks are still understudied despite their importance in understanding the mechanisms of these major disturbances. Because fragmentation may negatively impact species occupancy, abundance and co-occurrence, we predict a link between spatiotemporal changes in habitat and the architecture of host–parasite networks. 2. For this, we used an extensive data set on 16 rodent species and 29 helminth species...
Data from: Assessing the distribution of disease-bearing rodents in human-modified tropical landscapesSerge Morand, Frédéric Bordes, Kim Blasdell, Shai Pilosof, Jean-François Cornu, Kittipong Chaisiri, Yannick Chaval, Jean-François Cosson, Julien Claude, Tristan Feyfant, Vincent Herbreteau, Stéphane Dupuy & Annelise Tran
1. We tested how habitat structure and fragmentation affect the spatial distribution of common murine rodents inhabiting human-dominated landscapes in southeast Asia. The spatial distribution patterns observed for each rodent species were then used to assess how changes in habitat structure may potentially affect the risk of several major rodent-borne diseases. 2. For this analysis, we used an extensive geo-referenced database containing details of rodents trapped from seven sites in Thailand, Cambodia and Lao PDR....
Data from: Structure and extent of DNA methylation-based epigenetic variation in wild emmer wheat (T. turgidum ssp. dicoccoides) populationsAnna Venetsky, Adva Levy-Zamir, Vadim Khasdan, Katherine Domb & Khalil Kashkush
Background: The genetic structure and differentiation of wild emmer wheat suggests that genetic diversity is eco-geographically structured. However, very little is known about the structure and extent of the heritable epigenetic variation and its influence on local adaptation in natural populations. Results: The structure and extent of the heritable methylation-based epigenetic variation were assessed within and among natural populations of Triticum turgidum ssp. dicoccoides. We used methylation sensitive amplified polymorphism (MSAP) and transposon methylation display...
Data from: Novel evidence suggests that a \"Rickettsia felis-like\" organism is an endosymbiont of the desert flea, Xenopsylla ramesisSabine Rzotkiewicz, Ricardo Gutiérrez, Boris R. Krasnov, Danny Morick, Irina S. Khokhlova, Yaarit Nachum-Biala, Gad Baneth & Shimon Harrus
Fleas are acknowledged vectors and reservoirs of various bacteria that present a wide range of pathogenicity. In this study, fleas collected from wild rodents from the Negev desert in southern Israel were tested for RickettsiaDNA by targeting the 16S rRNA (rrs) gene. Thirty-eight Xenopsylla ramesis, 91 Synosternus cleopatrae and 15 Leptopsylla flea pools (a total of 568 fleas) were screened. RickettsiaDNA was detected in 100% of the X. ramesis and in one S. cleopatrae flea...
Data from: Predicting the maximum earthquake magnitude from seismic data in Israel and its neighboring countriesMark Last, Nitzan Rabinowitz & Gideon Leonard
This paper explores several data mining and time series analysis methods for predicting the magnitude of the largest seismic event in the next year based on the previously recorded seismic events in the same region. The methods are evaluated on a catalog of 9,042 earthquake events, which took place between 01/01/1983 and 31/12/2010 in the area of Israel and its neighboring countries. The data was obtained from the Geophysical Institute of Israel. Each earthquake record...
The evolution of sex is one of the greatest mysteries in evolutionary biology. An even greater mystery is the evolution of obligate sex, particularly when competing with facultative sex and not with complete asexuality. Here, we develop a stochastic simulation of an obligate allele invading a facultative population, where males are subject to sexual selection. We identify a range of parameters where sexual selection can contribute to the evolution of obligate sex: Especially when the...
