    Evolutionary flexibility in five hummingbird/plant mutualistic systems: testing temporal and geographic matching

    Journal of Biogeography.

    Aim Partners in co-evolutionary interactions must be ecologically interdependent and at least at some stage have matching traits and more or less overlapping ranges. As co-evolution is a process, neither the mutual dependence nor the trait and range matching are expected to be static or perfect. Here we investigate the extent of evolutionary flexibility in tight pollination mutualisms between hummingbirds and plants, ranging from straight-billed species to sicklebills. Location The Americas. Methods The five considered pollination mutualisms are between the following hummingbird and plant...

    Craniomandibular Variation in the Taxonomically Problematic Gerbil Genus Gerbillus (Gerbillinae, Rodentia): Assessing the Influence of Climate, Geography, Phylogeny, and Size

    Journal of Mammalian Evolution 1-16.

    The taxonomy of Gerbillus, the most speciose gerbil genus, is highly debated. Of particular contention is the relationship of Dipodillus to Gerbillus; some consider it to be a closely related genus, while others synonymize it with Gerbillus—either with or without recognizing it as a subgenus. The main objective of this study is to test the validity of common taxonomic groupings within the Gerbillus-Dipodillus species complex, which was achieved by using geometric morphometrics to examine cranial and mandibular variation in 34 out of the 52 Gerbillus-Dipodillus species. Craniomandibular size...

    Historical gene flow constraints in a northeastern Atlantic fish: phylogeography of the ballan wrasse Labrus bergylta across its distribution range

    Royal Society Open Science 4(2) 160773.

    The distribution and demographic patterns of marine organisms in the north Atlantic were largely shaped by climatic changes during the Pleistocene, when recurrent glacial maxima forced them to move south or to survive in northern peri-glacial refugia. These patterns were also influenced by biological and ecological factors intrinsic to each species, namely their dispersion ability. The ballan wrasse (Labrus bergylta), the largest labrid fish along Europe's continental margins, is a target for fisheries and aquaculture industry. The phylogeographic pattern, population structure, potential...

    A new species of Bertiella (Melanommataceae) from Brazil and a key to accepted species

    Mycosphere 8(4) 392-396.

    During an inventory of ascomycetes in the semi-arid region of Brazil, an undescribed specimen of Bertiella was found. It is described and illustrated as B. gelatinosa sp. nov., based on morphological data. The new fungus is distinguished by the size of the ascospores, which are surrounded by a gelatinous sheath. A synoptic table and a key to all known species of Bertiella are presented.

    A new species of the genus Bertholdia Schaus, 1896 (Lepidoptera: Erebidae: Arctiinae) from the Neotropical region: Bertholdia zoenia sp. n.

    Zootaxa 4238(1) 88.

    A new species of Bertholdia Schaus is described: Bertholdia zoenia sp. n., based on males and females from Argentina and Paraguay. This new species is closer to Bertholdia myosticta Hampson, 1901 from Costa Rica, Irazú. Bertholdia zoenia sp. n. can be recognized externally because its hyaline spot on forewing is the widest among all species of genus. Also, the shape of this hyaline spot is like a right triangle with smooth outer margin, different from other species of genus, which have an irregular spot. Habitus, male and female genitalia, and particular structures of B. zoenia sp. n. are...

    Changes in the realized niche of the invasive succulent CAM plant Furcraea foetida

    Austral Ecology.

    Furcraea foetida (Asparagaceae) is a native plant of Central America and northern South America but there is no information about its country of origin. The species was introduced into Brazil and is now considered invasive, particularly in coastal ecosystems. To date, nothing is known about the environmental factors that constrain its distribution and there is only inconclusive information about its location of origin. We used reciprocal distribution models (RDM) to assess invasion risk of F. foetida across Brazil and to identify source regions in its native range. We also tested the niche...

    Comparison of climate envelope models developed using expert-selected variables versus statistical selection

    Ecological Modelling 345 10-20.

    Climate envelope models are widely used to describe potential future distribution of species under different climate change scenarios. It is broadly recognized that there are both strengths and limitations to using climate envelope models and that outcomes are sensitive to initial assumptions, inputs, and modeling methods Selection of predictor variables, a central step in modeling, is one of the areas where different techniques can yield varying results. Selection of climate variables to use as predictors is often done using statistical approaches that develop correlations between...

    Taxonomy of Poa jubata and a new section of the genus (Poaceae)


    Poa jubata A. Kern. is an ephemeral, southeastern European species of which little is known. A molecular phylogenetic analysis of Poa L. including all previously identified major lineages, shows this species to be isolated, with a genotype here designated as J (plastid) J (nrDNA). It is assigned to the monotypic P. sect. Jubatae sect. nov. The section is differentiated from other Poa sections in having 5-nerved upper glumes, very narrow palea flanges, an annual habit, and erect solitary culms. Poa jubata occurs along coastal regions of the Balkans and is rather rare. Two new collections were...

    Detecting invertebrate species in archived collections using next-generation sequencing

    Molecular Ecology Resources.

    Invertebrate biodiversity measured at mostly family level is widely used in biological monitoring programmes to assess anthropogenic impacts on ecosystems. However, next-generation sequencing (NGS) could allow development of new more sensitive biomonitoring tools by allowing rapid species identification. This could be accelerated if archived invertebrate collections and environmental information from past programmes are used to understand species distributions and their environmental responses. In this study, we take archived macroinvertebrate samples from two sites collected on multiple...

    Migration corridors for alpine plants among the ‘sky islands’ of eastern Africa: do they, or did they exist?

    Alpine Botany 1-12.

    The tropical alpine ecosystem in eastern Africa is highly fragmented among biological ‘sky islands’, where populations of frost-tolerant organisms are isolated from each other by a ‘sea’ of tropical lowlands. One-third of the species in the afroalpine flora are exclusively alpine, but the other species can to varying degrees extend into grasslands and open forests of lower vegetation belts. A long-debated question is whether colonization of the alpine zone of these mountains and subsequent intermountain gene flow entirely depend on long-distance dispersal across unsuitable habitats, or...
