Data from: Projecting pest population dynamics under global warming: the combined effect of inter- and intra-annual variations

Royi Zidon, Hirotsugu Tsueda, Efrat Morin & Shai Morin
The typical short generation length of insects makes their population dynamics highly sensitive not only to mean annual temperatures but also to their intra-annual variations. To consider the combined effect of both thermal factors under global warming, we propose a modeling framework that links general circulation models (GCMs) with a stochastic weather generator and population dynamics models to predict species population responses to inter- and intra-annual temperature changes. This framework was utilized to explore future...

Data from: Composite collective decision making

Tomer J. Czaczkes, Benjamin Czaczkes, Carolin Iglhaut & Jürgen Heinze
Individual animals are adept at making decisions and have cognitive abilities, such as memory, which allow them to hone their decisions. Social animals can also share information. This allows social animals to make adaptive group-level decisions. Both individual and collective decision-making systems also have drawbacks and limitations, and while both are well studied, the interaction between them is still poorly understood. Here, we study how individual and collective decision-making interact during ant foraging. We first...

Data from: Colonization of the Mediterranean Basin by the vector biting midge species Culicoides imicola: an old story

Stephanie Jacquet, Claire Garros, Eric Lombaert, Catherine Walton, Johana Restrepo, Xavier Allene, Thierry Baldet, Catherine Cetre-Sossah, Alexandra Chaskopoulou, Jean-Claude Delecolle, Amelie Desvars, Mouloud Djerbal, Moussa Fall, Laetitia Gardes, Michel De Garine-Wichatitsky, Maria Goffredo, Yuval Gottlieb, Assane Gueye Fall, Muo Kasina, Karien Labuschagne, Youssef Lhor, Javier Lucientes, Thibaud Martin, Bruno Mathieu, Miguel Miranda … & J.-C. Delecolle
Understanding the demographic history and genetic make-up of colonizing species is critical for inferring population sources and colonization routes. This is of main interest for designing accurate control measures in areas newly colonized by vector species of economically important pathogens. The biting midge Culicoides imicola is a major vector of orbiviruses to livestock. Historically, the distribution of this species was limited to the Afrotropical region. Entomological surveys first revealed the presence of C. imicola in...

Data from: Sensitivity analysis of conservation targets in systematic conservation planning

Noam Levin, Tessa Mazor, Eran Brokovich, Pierre-Elie Jablon & Salit Kark
Systematic conservation planning has rapidly advanced in the past decade and has been increasingly incorporated in multiple studies and conservation projects. One of its requirements is a quantitative definition of conservation targets. While the Convention on Biological Diversity aims to expand the world's protected area network to 17% of the land surface, in many cases such uniform policy-driven targets may not be appropriate for achieving persistence of various species. Targets are often set arbitrarily, often...

Data from: Natural habitat does not mediate vertebrate seed predation as an ecosystem dis-service to agriculture

Jessica Schäckermann, Yael Mandelik, Noam Weiss, Henrik Von Wehrden & Alexandra-Maria Klein
1. Spillover of beneficial organisms from natural habitats to croplands can improve agro-ecosystem services, but wildlife can also negatively influence agricultural production. When managing agricultural landscapes to conserve biodiversity, we need to understand if the availability of natural habitats increases ecosystem dis-services such as vertebrate seed predation to avoid risking higher costs than benefits. 2. We studied whether vertebrates and their impact in crop seed predation are related to the percentage of natural (Chaparral) and...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: Heterochromatin Protein 1β (HP1β) has distinct functions and distinct nuclear distribution in pluripotent versus differentiated cells

Anna Mattout, Yair Aaronson, Badi Sri Sailaja, Edupuganti V. Raghu Ram, Arigela Harikumar, Jan-Philipp Mallm, Kae Hwan Sim, Malka Nissim-Rafinia, Emmanuelle Supper, Prim B. Singh, Siu Kwan Sze, Susan M. Gasser, Karsten Rippe & Eran Meshorer
Background: Pluripotent embryonic stem cells (ESCs) have the unique ability to differentiate into every cell type and to self-renew. These characteristics correlate with a distinct nuclear architecture, epigenetic signatures enriched for active chromatin marks and hyperdynamic binding of structural chromatin proteins. Recently, several chromatin-related proteins have been shown to regulate ESC pluripotency and/or differentiation, yet the role of the major heterochromatin proteins in pluripotency is unknown. Results: Here we identify Heterochromatin Protein 1β (HP1β) as...

Data from: Novel evidence suggests that a \"Rickettsia felis-like\" organism is an endosymbiont of the desert flea, Xenopsylla ramesis

Sabine 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...
