Abstract An understanding of the evolutionary history and dynamics invasive species is required for construction predictive models future spread design biological management measures. The black rat ( Rattus rattus ) a major vertebrate invader with worldwide distribution. Despite severe ecological, economic health impacts this species, its has been little studied. We carried out extensive specimen sampling in Senegal, West Africa, used microsatellite markers to describe pattern processes...
Abstract The worldwide intensification of human‐associated exchanges favours the multiplication biological invasions. Among mammals, rodent species, including house mouse M us musculus , are identified as major invaders with profound impacts on native biodiversity, human health and activities. Though contemporary invasions described several islands, there few data describing ongoing in continental areas. We first outline known picture distribution A frica. then describe range expansion S...
Animals are faced with a range of ecological constraints that shape their behavioural decisions. Habitat features affect resource abundance will also have an impact, especially as regards spatial distribution, which in turn associations between the animals. Here we utilised network approach, using and genetic data, to describe patterns use space (foraging sites) by free-ranging Egyptian fruit bats (Rousettus aegyptiacus) at Dakhla Oasis Egypt. We observed decrease home size during spring,...
Abstract An understanding of recent evolutionary processes is essential for the successful conservation and management contemporary populations, especially where they concern introduction or invasion species outside their natural range. However, potentially negative implications intraspecific introductions invasions have attracted less attention, although also represent a potential threat to biodiversity, are commonly facilitated through human activities. The European bitterling ( Rhodeus...
Abstract Two sibling species of the rodent genus Praomys occur in West African forests: P. tullbergi and rostratus . By sampling across their geographical ranges (459 individuals from 77 localities), we test hypothesis that climatic oscillations during Quaternary made an impact on observed pattern cytochrome b sequence variation. We show that, although these two have parapatric distributions, phylogeographical histories are dissimilar, which could be related to distinct ecological...
Abstract Rodents of the Praomys daltoni complex are typical inhabitants Sudanian savanna ecosystem in western Africa and represent a suitable model for testing effects Quaternary climatic oscillations on extant genetic variation patterns. Phylogeographical analyses mitochondrial DNA sequences (cytochrome b ) across distribution range revealed several well‐defined clades that do not support division clade into two species currently recognized basis morphology, i.e. P. (Thomas, 1892) derooi (...
Understanding the invasive potential of species outside their native range is one most pressing questions in applied evolutionary and ecological research. Admixture genotypes from multiple sources has been implicated successful invasions, by generating novel genetic combinations that facilitate rapid adaptation to new environments. Alternatively, adaptive evolution on standing variation, exposed phenotypic plasticity selected accommodation, can invasion success. We investigated population...

Lecanosticta acicola is a heterothallic ascomycete that causes brown spot needle blight on native and nonnative Pinus spp. in many regions of the world. In this study we investigated origin European L. populations estimated level random mating pathogen affected areas. Part elongation factor 1-α gene was sequenced, 11 microsatellite were screened, type idiomorphs determined for 201 isolates collected from three continents 17 host species. The Mexico Guatemala unique, highly diverse could...
Dothistroma septosporum, the primary causal agent of needle blight, is one most significant foliar pathogens pine worldwide. Its wide host and environmental ranges have led to its global success as a pathogen severe economic damage forests in many regions. This comprehensive population study elucidated historical migration pathways reveal Eurasian origin fungus. When over 3800 isolates were examined, three major clusters revealed: North America, Western Europe, Eastern with distinct...
Exotic forest insects and their symbionts pose an increasing threat to health. This is apparently true for the red turpentine beetle (Dendroctonus valens), which was unintentionally introduced China, where has killed millions of healthy native pine trees. Previous population genetics studies that used cytochrome oxidase I as a marker concluded source D. valens in China western North America. In contrast, surveys fungi associated with demonstrated more fungal species are shared between...
Abstract Aim This study aims to reconstruct the evolutionary history of Crocidura poensis species complex and identify factors driving diversification within it. We tested whether: (a) there is a pattern allopatric differentiation coincident with location hypothesized Pleistocene forest refugia, (b) sister taxa are separated by broad rivers, (c) occupy adjacent but distinct habitat. Location Sub‐Saharan African forests savanna. Taxon Shrews. Methods Analyses were based on 247 specimens...
We describe two new species of white-toothed shrews from south-western and central Ethiopia, based on recent collections an application morphological genetic methods, Crocidura similiturba sp. nov. makeda Comparisons are provided with other known to occur in the country. Both currently only Ethiopian Highlands. Furthermore, we provide geographical records discuss biogeographical patterns New molecular data, even if primarily mitochondrial cytochrome b, suggests substantial divergence within...
Abstract Moths (Lepidoptera) are major agricultural and forest pests in many parts of the world, including Europe, with causing great economic damage to crops, horticultural plants, stored items, wool products. Here, we focus on two ecologically similar inchworms, Operophtera brumata Erannis defoliaria , known for their high foliage consumption during spring emergence caterpillars. We hypothesise that bats could play a role reducing such as caterpillars by switching this abundant emerging...
We isolated and characterized 10 microsatellite loci in the black rat Rattus rattus (Muridae, Rodentia), a widespread invasive species largely known to cause serious problems agriculture human health. Polymorphism was studied two populations, one from Madagascar Senegal. It ranged three 12 alleles Madagascar, five Together with previously adapted norvegicus, this set of markers should allow conduct thorough studies on genetic structure natural populations R. rattus.
Abstract The crucial steps in biological invasions, related to the shaping of genetic architecture and current evolution adaptations a novel environment, usually occur small populations during phases introduction establishment. However, these processes are difficult track nature due invasion lag, large geographic temporal scales compared with human observation capabilities, frequent depletion variance, admixture other phenomena.
