Data from: Ecological consequences of parasite host shifts under changing environments: more than a change of partner

Ana Mellado
(1) Parasitic plants, among many other parasitic organisms, are shifting in their geographic distribution in response to global change, establishing novel interactions with susceptible but previously unexposed host plants. Projections of future species assemblages in increasingly changing environments frequently overlook the strong capacity of these parasites to transform ecological systems, and host switching is considered a mere change of partner with no subsequent impact on ecosystem properties. (2) We explore the ecological consequences of parasite...

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...

Data from: Great spotted cuckoo eggshell microstructure characteristics can make eggs stronger

Manuel Soler, Alejandro Rodriguez-Navarro, Tomás Pérez-Contreras, Juan García-Ruiz & Juan Soler
Obligate avian brood parasites lay stronger eggs than their hosts or non-parasitic relatives because they are rounder and have a thicker eggshell. Additionally, some other characteristics of the brood parasitic eggshells related to their microstructure such as size and orientation of calcite crystal units could also contribute to generating even stronger shells. An eggshell microstructure formed by small randomly oriented calcite crystal units can increase the robustness of the eggshells of birds. Here, the eggshell...

Data from: Great spotted cuckoos show dynamic patterns of host selection during the breeding season

Manuel Soler, Tomás Perez-Contreras & Juan José Soler
Avian brood parasites depend entirely on their hosts to raise their nestlings until independence. Thus, parasite females should select suitable host nests for egg laying according to traits that enhance offspring survival. Availability of nests of certain characteristics influencing survival of parasitic offspring is however temporally dynamic and, thus, patterns of host selection should be evaluated considering characteristics of available host nests the day of parasitism. This allows detecting possible seasonal changes and, therefore, a...

Age-related brood parasitism and egg rejection in magpie hosts

Juan Gabriel Martinez Suarez, Mercedes Molina-Morales, Marta Precioso & Jesus Miguel Avilés
When the strength or nature of a host -parasite interaction changes over the host life cycle, the consequences of parasitism can depend on host population age structure. Avian brood parasites reduce hosts’ breeding success, and host age may play a role in this interaction if younger hosts are more likely parasitized and/or less able to defend themselves. We analyzed whether the age of female magpies (Pica pica) hosts is associated with parasite attack or their...
