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...

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: The cutaneous lipid composition of bat wing and tail membranes: a case of convergent evolution with birds

Miriam Ben-Hamo, Agusti Muñoz-Garcia, Paloma Larrain, Berry Pinshow, Carmi Korine & Joseph Williams
The water vapour permeability barrier of mammals and birds resides in the stratum corneum (SC), the outermost layer of the epidermis. The molar ratio and molecular arrangement of lipid classes in the SC determine the integrity of this barrier. Increased chain length and polarity of ceramides, the most abundant lipid class in mammalian SC, contribute to tighter packing and thus to reduced cutaneous evaporative water loss (CEWL). However, tighter lipid packing also causes low SC...
