Data from: Habitat fragmentation alters the properties of a host-parasite network: rodents and their helminths in South-East Asia

Frédéric 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: Copulation with immature females increases male fitness in cannibalistic widow spiders

M. Daniela Biaggio, Iara Sandomirsky, Yael Lubin, Ally R. Harari, Maydianne C.B. Andrade & Maydianne C. B. Andrade
Copulatory cannibalism of male ‘widow’ spiders (genus Latrodectus) is a model example of the extreme effects of sexual selection, particularly in L. hasselti and L. geometricus where males typically facilitate cannibalism by females and mate only once. We show that these males can increase their reproductive success by copulating with final-instar, immature females after piercing the female's exoskeleton to access her newly developed sperm storage organs. Females retain sperm through their final moult and have...

Short-term prediction through ordinal patterns

Yair Neuman, Yair Neuman, Yohai Cohen & Boaz Tamir
Prediction in natural environments is a challenging task, and there is a lack of clarity around how a myopic organism can make short-term predictions given limited data availability and cognitive resources. In this context, we may ask what kind of resources are available to the organism to help it address the challenge of short-term prediction within its own cognitive limits. We point to one potentially important resource: ordinal patterns, which are extensively used in physics...

Experimental evidence of multiple ecosystem services and disservices provided by ecological intensification in Mediterranean agro-ecosystems

Hila Segre, Michal Segoli, Yohay Carmel & Assaf Shwartz
1. Intensifying agricultural production in sustainable ways is pivotal to increasing food production while reducing environmental impacts. Ecological intensification is based on managing organisms that provide services underlying crop production to simultaneously intensify agricultural production and increase biodiversity. However, few studies address the interactions and trade-offs between biodiversity, multiple ecosystem services and crop production. 2. We experimentally quantified the effect of uncultivated field margins, a prominent practice of ecological intensification, on agricultural production, biodiversity, as...

Predation on Vachellia trees in the Evrona Nature Reserve following an oil spill

Marco Ferrante, Daniella Möller, Gabriella Möller, Esteban Menares, Yael Lubin & Michal Segoli
The Evrona Nature Reserve (southern Israel; 29°40′N, 35°00′E) was affected by two large oil spills in 1975 and 2014, respectively. Between Nov 2019 to Oct 2019, we recorded invertebrate and vertebrate predation rates using the artificial caterpillar method (Howe et al. 2009, Entomol Exp App) in oil-polluted and unpolluted Vachellia trees.

Rolle-Kampczyk, Sven-Bastiaan Haange, Kieran M. Tuohy, Camilla Diotallevi, Ilan Shelef, Frank B. Hu, Meir J. Stampfer & Iris Shai
Abstract Background Mediterranean (MED) diet is a rich source of polyphenols, which benefit adiposity by several mechanisms. We explored the effect of the green-MED diet, twice fortified in dietary polyphenols and lower in red/processed meat, on visceral adipose tissue (VAT). Methods In the 18-month Dietary Intervention Randomized Controlled Trial PoLyphenols UnproceSsed (DIRECT-PLUS) weight-loss trial, 294 participants were randomized to (A) healthy dietary guidelines (HDG), (B) MED, or (C) green-MED diets, all combined with physical activity....

Social and structural determinants of emergency department use among Arab and Jewish patients in Jerusalem

Shifra Unger, Zvika Orr, Evan Avraham Alpert, Nadav Davidovitch & Ilana Shoham-Vardi
Abstract Background A growing body of research demonstrates that economic conditions and racial and ethnic disparities result in excessive overuse of emergency departments (EDs) by a small group of socioeconomically marginalized residents. Knowledge and understanding of these issues on the part of the healthcare team can promote equality by providing structurally competent care. This study aims to identify the major social and structural factors related to patterns of ED visits by Arab and Jewish patients...

Characterization of diazotrophic root endophytes in Chinese silvergrass (Miscanthus sinensis)

Yongbin Li, Rui Yang, Max M. Häggblom, Mengyan Li, Lifang Guo, Baoqin Li, Max Kolton, Zhiguo Cao, Mohsen Solemani, Zheng Chen, Zhimin Xu, Wenlong Gao, Bei Yan & Weimin Sun
Abstract Background Phytoremediation is a potentially cost-effective way to remediate highly contaminated mine tailing sites. However, nutrient limitations, especially the deficiency of nitrogen (N), can hinder the growth of plants and impair the phytoremediation of mine tailings. Nevertheless, pioneer plants can successfully colonize mine tailings and exhibit potential for tailing phytoremediation. Diazotrophs, especially diazotrophic endophytes, can promote the growth of their host plants. This was tested in a mine-tailing habitat by a combination of field...

Data from: Alternative paths to success in a parasite community: within-host competition can favor higher virulence or direct interference

Farrah Bashey-Visser, Hadas Hawlena & Curtis M. Lively
Selection imposed by coinfection may vary with the mechanism of within-host competition between parasites. Exploitative competition is predicted to favor more virulent parasites, while interference competition may result in lower virulence. Here, we examine whether exploitative or interference competition determines the outcome of competition between two nematode species (Steinernema spp.), which in combination with their bacterial symbionts (Xenorhabdus spp.), infect and kill insect hosts. Multiple isolates of each nematode species, carrying their naturally associated bacteria,...

Data from: Structure and extent of DNA methylation-based epigenetic variation in wild emmer wheat (T. turgidum ssp. dicoccoides) populations

Anna 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: Temporal dynamics of direct reciprocal and indirect effects in a host-parasite network

Shai Pilosof, Miguel A. Fortuna, Maxim V. Vinarski, Natalia P. Korallo-Vinarskaya & Boris R. Krasnov
1. Temporal variation in the direct and indirect influence that hosts and parasites exert on each other is still poorly understood. However, variation in species’ influence due to species and interactions turnover can have important consequences for host community dynamics and/or for parasite transmission dynamics, and eventually for the risk of zoonotic diseases. 2. We used data on a network of small mammals and their ectoparasites surveyed over six years to test hypotheses exploring (1)...

Data from: Good reasons to leave home: proximate dispersal cues in a social spider

Reut Berger-Tal, Na'ama Berner Aharon, Shlomi Aharon, Cristina Tuni & Yael Lubin
Natal dispersal is a successful tactic under a range of conditions in spite of significant costs. Habitat quality is a frequent proximate cause of dispersal, and studies have shown that dispersal increases both when natal habitat quality is good or poor. In social species kin competition, favoring dispersal, may be balanced by the benefits of group living, favoring philopatry. We investigated the effect of changes in the local environment on natal dispersal of adult females...

Data from: Various competitive interactions explain niche separation in crop-dwelling web spiders

Itai Opatovsky, Efrat Gavish-Regev, Phyllis G. Weintraub & Yael Lubin
Competition for resources is a major organizing principle in communities of organisms that share similar ecological niches. Niche separation by means of exploitation or interference competition was investigated in two taxa of crop-inhabiting spiders that overlap in microhabitat use and have similar web design. Competition for prey and web sites was tested in microcosm experiments with the most common species that build sheet-webs: Enoplognatha gemina (Theridiidae) and Alioranus pastoralis (Linyphiidae). A field survey over the...

Data from: Energy exchanges at contact events guide sensorimotor integration across intermodal delays

Ali Farshchian, Alessandra Sciutti, Assaf Pressman, Ilana Nisky & Ferdinando A Mussa-Ivaldi
The brain must consider the arm's inertia to predict the arm's movements elicited by commands impressed upon the muscles. Here, we present evidence suggesting that the integration of sensory information leading to the representation of the arm's inertia does not take place continuously in time but only at discrete transient events, in which kinetic energy is exchanged between the arm and the environment. We used a visuomotor delay to induce cross-modal variations in state feedback...

Data from: Palaeobiogeography and evolutionary patterns of the larger foraminifer Borelis de Montfort (Borelidae)

Davide Bassi, Juan Carlos Braga, Giovanni Di Domenico, Johannes Pignatti, Sigal Abramovich, Pamela Hallock, Janine Koenen, Zoltan Kovacs, Martin R. Langer, Giulio Pavia & Yasufumi Iryu
The palaeobiogeography of the alveolinoid Borelis species reveals the evolutionary patterns leading to the two extant representatives, which occur in shallow-water tropical carbonate, coral reef-related settings. Type material and new material of fossil Borelis species, along with Recent specimens were studied to assess their taxonomic status, species circumscriptions (based on proloculus size, occurrence of Y-shaped septula, and the index of elongation), palaeobiogeography and evolutionary dynamics. The species dealt with here are known from exclusively fossil...

FragSAD: A database of diversity and species abundance distributions from habitat fragments

Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non‐standardized sampling methodology and analyses of notoriously scale‐dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation...

Data from: Contrasting global patterns of spatially periodic fairy circles and regular insect nests in drylands

Stephan Getzin, Hezi Yizhaq, Michael D. Cramer & Walter R. Tschinkel
Numerical analysis of spatial pattern is widely used in ecology to describe the characteristics of floral and faunal distributions. These methods allow attribution of pattern to causal mechanisms by uncovering the specific signatures of patterns and causal agents. For example, grassland‐gap patterns called fairy circles (FCs) in Namibia and Australia are characterized by highly regular and homogenous distributions across landscapes that show spatially periodic ordering. These FCs have been suggested to be caused by both...

Harrison’s rule scales up to entire parasite assemblages but is determined by environmental factors

Renan Maestri, Maico Fiedler, Georgy Shenbrot, Elena Surkova, Sergei Medvedev, Irina Khokhlova & Boris Krasnov
Harrison’s rule states that parasite body size and the body size of their hosts tend to be positively correlated. After it was proposed a century ago, a number of studies have investigated this trend, but the support level has varied greatly between parasite/host associations. Moreover, while the rule has been tested at the individual species level, we still lack knowledge on whether Harrison’s rule holds at the scale of parasite and host communities. Here, we...

Computational quantification and characterization of independently evolving cellular subpopulations within tumors is critical to inhibit anti-cancer therapy resistance

Heba Alkhatib, Ariel M. Rubinstein, Swetha Vasudevan, Efrat Flashner-Abramson, Shira Stefansky, Sangita Roy Chowdhury, Solomon Oguche, Tamar Peretz-Yablonsky, Avital Granit, Zvi Granot, Ittai Ben-Porath, Kim Sheva, Jon Feldman, Noa E. Cohen, Amichay Meirovitz & Nataly Kravchenko-Balasha
Abstract Background Drug resistance continues to be a major limiting factor across diverse anti-cancer therapies. Contributing to the complexity of this challenge is cancer plasticity, in which one cancer subtype switches to another in response to treatment, for example, triple-negative breast cancer (TNBC) to Her2-positive breast cancer. For optimal treatment outcomes, accurate tumor diagnosis and subsequent therapeutic decisions are vital. This study assessed a novel approach to characterize treatment-induced evolutionary changes of distinct tumor cell...
