Range expansion results from complex eco-evolutionary processes where range dynamics and niche shifts interact in a novel physical space and/or environment, with scale playing a major role. Obligate symbionts (i.e. organisms permanently living on hosts) differ from free-living organisms in that they depend on strong biotic interactions with their hosts which alter their niche and spatial dynamics. A symbiotic lifestyle modifies organism-environment relationships across levels of organisation, fr...

1.The role of biotic interactions in shaping the distribution and abundance of species should be particularly pronounced in symbionts. Indeed, symbionts have a dual niche composed of traits of their individual hosts and the abiotic environment external to the host, and often combine active dispersal at finer scales with host‐ mediated dispersal at broader scales. The biotic complexity in the determinants of species distribution and abundance should be even more pronounced for hypersymbionts (sym...

Natural enemies, that is, species that inflict harm on others while feeding on them, are fundamental drivers of biodiversity dynamics and represent a substantial portion of biodiversity as well. Along the life history of the Earth, natural enemies have been involved in probably some of the most productive mechanisms of biodiversity genesis; that is, adaptive radiation mediated by enemy-victim coevolutionary processes. At ecological timescales, natural enemies are a fundamental piece of food webs...

Here we analyse in detail, for the first time, the growth pattern of the endangered freshwater mussel Margaritifera auricularia in the Ebro basin, a life history trait essential for conservation purposes. We combined information on size and age from captive bred juveniles, together with growth annuli from living preadults studied in the field, and empty shells of preadult and adult individuals. We compared the fit of six types of (asymptotic and sigmoid) non-linear growth models and, in terms of...

Do host invaders and their associated symbiont co-invaders have different genetic responses to the same invasion process? To answer this question, we compared genetic patterns of native and exotic populations of an invasive symbiont-host association. This is an approach applied by very few studies, of which most are based on parasites with complex life cycles. We used the mitochondrial genetic marker cytochrome oxidase subunit I (COI) to investigate a non-parasitic freshwater ectosymbiont with d...

Symbiont spillover involves the emergence of new interactions that can influence both the symbiont and the host invasion processes. Here we aimed at experimentally testing the transmission of an exotic ectosymbiont, Ankylocythere sinuosa (Ostracoda, Entocytheridae), from a crayfish invader (Procambarus clarkii) to a native European crayfish (Austropotamobius italicus). Crayfish transmitter and receiver were placed in the same container during 4 days. Three experimental treatments were designed: ...

Summary Symbiosis represents a widespread and successful lifestyle, but research on symbiotic associations has been mainly focused on parasites. Three general patterns in parasite ecology have been proposed: (i) aggregation, (ii) positive and tight correlation between mean symbiont abundance and its variance and (iii) positive correlation between abundance and prevalence of symbionts. The factors affecting abundance and prevalence within symbiont species can be grouped into host features and env...

Understanding why host species differ so much in symbiont loads and how this depends on ecological host and symbiont traits is a major issue in the ecology of symbiosis. A first step in this inquiry is to know whether observed differences among host species are species-specific traits or more related with host-symbiont environmental conditions. Here we analysed the repeatability (R) of the intensity and the prevalence of feather mites to partition within- and among-host species variance componen...

correspondence ISSN 1948-6596 The shoemaker’s son always goes barefoot: intercontinental dis- persal of Ostracoda (Crustacea) by scientists attending an IBS excursion Human activity is one of the main mechanisms through which alien species are dispersed, often unintentionally. Freshwater alien species com- monly are transported between continents by vectors such as ballast water or ship transport of commercial stocks for aquaculture or agriculture (Amat et al. 2005, Escriva et al. 2012, Strayer ...
