Abstract Although mutualistic associations between animals and microbial symbionts are widespread in nature, the mechanisms that have promoted their evolutionary persistence remain poorly understood. A vertical mode of symbiont transmission (from parents to offspring) is thought ensure partner fidelity stabilization, although efficiency has rarely been investigated, especially cases where hosts harbour a diverse community. Here we evaluated rates cellulolytic gut oxymonad parabasalid...
Abstract As native ranges are often geographically structured, invasive species originating from a single source population only carry fraction of the genetic diversity present in their range. The invasion process is thus associated with drastic loss resulting founder event. However, brought to range may vary under different histories, increasing size propagule, number reintroduction events, and/or total represented by various populations multiple‐introduction scenario. In this study, we...
Elasticity is the intrinsic element that differentiates Cloud computing from traditional paradigm, since it allows service providers to rapidly adjust their needs for resources absorb demand and hence guarantee a minimum level of Quality Service (QoS) respects Level Agreements (SLAs) previously defined with clients. However, due non-negligible resource initiation time, network fluctuations or unpredictable workload, becomes hard QoS levels SLA violations may occur. This paper proposes...
Abstract Background Although much research has been carried out into European Reticulitermes taxonomy in recent years, there is still discussion about phylogenetic relationships. This study investigated the evolution from intra- to interspecific phylogeny island subspecies lucifugus corsicus and threw new light on this phenomenon. An integrative approach based microsatellites mitochondrial nuclear DNA sequences was used analyze samples taken a wide area around Tyrrhenian sea showed how...
Abstract Parental care is a major component of reproduction in social organisms, particularly during the foundation steps. Because investment into parental often costly, each parent predicted to maximize its fitness by providing less than partner. However, this sexual conflict expected be low species with lifelong monogamy, because typically tied other's input. Somewhat surprisingly, outcomes tug‐of‐war between maternal and paternal investments have received important attention vertebrate...
In spite of the indubitable advantages elasticity in Cloud infrastructures, some technical and conceptual limitations are still to be considered. For instance, resource start up time is generally too long react unexpected workload spikes. Also, billing cycles' granularity existing pricing models may incur consumers suffer from partial usage waste. We advocate that software layer can take part process as overhead reconfigurations usually considered negligible if compared infrastructure one....
Abstract A long‐standing goal of evolutionary biology is to understand how paleoclimatic and geological events shape the geographical distribution genetic structure within among species. Using a diverse set markers (cuticular hydrocarbons, mitochondrial nuclear gene sequences, microsatellite loci), we studied Reticulitermes grassei R. banyulensis, two closely related termite species in southwestern Europe. We sought clarify current populations that formed following postglacial dispersal from...
The microbes residing within the gut of an animal host often increase their own fitness by modifying host's physiological, reproductive and behavioural functions. Whereas recent studies suggest that they may also shape sociality therefore have critical effects on social evolution, impact microbiota maternal care remains unexplored. This is surprising, as this behaviour widespread among animals, determines both juveniles parents, essential in evolution complex societies. Here, we tested...
Depositing eggs in an area with adequate temperature is often crucial for mothers and their offspring, as the are immobile therefore cannot avoid exposure to sub-optimal temperatures. However, importance of on oviposition site selection less clear when can these potential adverse effects by both moving after providing other forms egg care. In this study, we addressed question European earwig, insect which care during several months winter, frequently them period. We set up 60 females from...
In population genetics studies, detecting and quantifying the distribution of genetic variation can help elucidate ecological evolutionary processes. social insects, population-level variability is generally linked to colony-level structure. It thus especially crucial conduct complementary analyses on such organisms examine how spatial constraints interact shape patterns intraspecific diversity. this study, we sequenced mitochondrial COII gene for 52 colonies subterranean termite...
Termites are social insects that can also be major pests. A well-known problem species is the subterranean termite, Reticulitermes flavipes. It invasive in France and thought to have arrived from Louisiana during 18th century. While putative source of French populations has been identified, little known about how termite spread following its establishment. Here, we examined expansion patterns at different spatial scales urban areas clarify R. flavipes France. Based on our analyses...
1. Being able to detect a predator before any physical contact is crucial for individual survival. Predator presence can be detected thanks several types of signal, such as chemical cues. Chemical signals are produced by predators their protection against desiccation, communication, or possibly side‐effect activity. In insects, communication plays key role in diverse biological processes, including prey‐predator plant‐insect interactions, courtship behaviour, and kin species recognition. 2....
Invasive species cause severe environmental and economic problems. The invasive success of social insects often appears to be related their ability adjust organization new environments. To gain a better understanding the biology termites, this study investigated subterranean termite, Reticulitermes urbis, analyzing breeding structure number reproductives within colonies from three introduced populations. By using eight microsatellite loci determine genetic structure, it was found that all...
Summary In many animals, male weapons are large and extravagant morphological structures that typically enhance fighting ability reproductive success. It is generally assumed growing carrying costly, thus only males in the best condition can afford it. European earwig, carry form of forceps-like cerci, which vary widely size within populations. While long forceps appear to increase male’s access females, it unknown whether also correlates with other important lifen-history traits. This...
The co-evolutionary pathways followed by hosts and parasites strongly depend on the adaptive potential of antagonists its underlying genetic architecture. Geographically structured populations interacting species often experience local differences in strength reciprocal selection pressures, which can result a geographic mosaic co-evolution. One example such system is boreo-montane social wasp Polistes biglumis parasite atrimandibularis, have evolved defense counter-defense mechanisms to...

This invasion pathway is thus associated with drastic loss resulting founder event. However, brought to range may vary under different histories, increasing size propagule, number re-introduction events, and/or total represented by various populations multiple-introduction scenario.
