Data from: Spider webs, stable isotopes and molecular gut content analysis: multiple lines of evidence support trophic niche differentiation in a community of Hawaiian spiders
1. Adaptive radiations are typically characterized by niche partitioning among their constituent species. Trophic niche partitioning is particularly important in predatory animals, which rely on limited food resources for survival. 2. We test for trophic niche partitioning in an adaptive radiation of Hawaiian Tetragnatha spiders, which have diversified in situ on the Hawaiian Islands. We focus on a community of nine species belonging to two different clades, one web building and the other actively hunting, which co-occur in wet forest on East Maui. We hypothesize that trophic niches differ significantly both 1) among species within a clade, indicating food resource partitioning, and 2) between the two clades, corresponding with their differences in foraging strategy. 3. To assess niches of the spider species, we measure a) web architecture, the structure of the hunting tool, and b) site choice, the physical placement of the web in the habitat. We then test whether differences in these parameters translate into meaningful differences in trophic niche by measuring c) stable isotope signatures of carbon and nitrogen in the spiders' tissues, and d) gut content of spiders based on metabarcoding data. 4. We find significant interspecific differences in web architecture and site choice. Importantly, these differences are reflected in stable isotope signatures among the five web-building species, as well as significant isotopic differences between web-builders and active hunters. Gut content data also show interspecific and inter-clade differences. Pairwise overlaps of web architecture between species are positively correlated with overlaps of isotopic signature. 5. Our results reveal trophic niche partitioning among species within each clade, as well as between the web-building and actively hunting clades. Based on the correlation between web architecture and stable isotopes, it appears that the isotopic signatures of spiders' tissues are influenced by architectural differences among their webs. Our findings indicate an important link between web structure, microhabitat preference and diet in the Hawaiian Tetragnatha.
Reassessment of Chirita umbrophila (Gesneriaceae) based on molecular and morphological evidence
<p><em>Chirita umbrophila</em> C.Y.Wu ex H.W.Li is a species endemic to Yunnan, China, and its exact systematic position remains a mystery since it was treated as a species with uncertain generic affiliation in the taxonomic revision of <em>Chirita</em> Buch.-Ham. ex Don in 1985. In the present study, the phylogenetic relationships between <em>C. umbrophila</em> and its allied species were inferred using two nuclear ribosomal DNA regions (ETS and ITS) and three chloroplast regions (<em>rpl16</em>, <em>rps16</em>, and <em>trnL-F</em>). Additionally, the type locality of <em>C. umbrophila</em> was re-visited and flowering specimens were collected and examined. Our phylogenetic analyses showed that <em>Chirita umbrophila</em> is imbedded in three accessions of <em>Loxostigma kurzii</em> with strong support. Morphological observations revealed that <em>C. umbrophila</em> can be characterized as perennial herbs with somewhat tufted leaves at the top of the aerial stem, large ventricose corollas with yellow-brown spotted interior surfaces, four anthers cohering in pairs, and two equal or subequal stigmas. Detailed morphological analyses suggested that <em>C. umbrophila</em> is indistinguishable from <em>Loxostigma kurzii </em>(C.B.Clarke) B.L.Burtt (<em>Didymocarpus? kurzii</em> C.B.Clarke). Therefore, both molecular phylogenetic results and morphological evidence support that <em>Chirita umbrophila</em> is conspecific with <em>Loxostigma kurzii</em>, and a taxonomic treatment is provided<em> </em>herein.</p>

A range-wide postglacial history of Swiss stone pine based on molecular markers and palaeoecological evidence
<p><strong><span>Aim: </span></strong><span>Knowing a species' response to historical climate shifts helps understanding its perspectives under global warming.<strong> </strong>We infer the hitherto unresolved postglacial history of <em>Pinus cembra.</em> Using independent evidence from genetic structure and demographic inference of extant populations, and from palaeoecological findings, we derive putative refugia and re-colonisation routes.</span></p> <p><strong><span>Location: </span></strong><span>European Alps and Carpathians.</span></p> <p><strong><span>Taxa: </span></strong><em><span>Pinus cembra.</span></em></p> <p><strong><span>Methods: </span></strong><span>We genotyped nuclear and chloroplast microsatellite markers in nearly 3,000 individuals from 147 locations across the entire natural range of <em>P. cembra</em>. Spatial genetic structure (Bayesian modelling) and demographic history (Approximate Bayesian Computation) were combined with palaeobotanical records (pollen, macrofossils) to infer putative refugial areas during the Last Glacial Maximum (LGM) and re-colonisation of the current range.</span></p> <p><strong><span>Results: </span></strong><span>We found distinct spatial genetic structure, despite low genetic differentiation even between the two disjunct mountain ranges. Nuclear markers revealed five genetic clusters aligned East–West across the range, while chloroplast haplotype distribution suggested nine clusters. Spatially congruent separation at both marker types highlighted two main genetic lineages in the East and West of the range. Demographic inference supported early separation of these lineages dating back to a previous interstadial or interglacial <em>c.</em> 210,000 years ago. Differentiation into five biologically meaningful genetic clusters likely established during post-glacial re-colonisation.</span></p> <p><strong><span>Main conclusions: </span></strong><span>Combining genetic and palaeoecological evidence suggests that <em>P. cembra</em> primarily survived the LGM in "cold period" refugia south of the Central European Alps and near the Carpathians, from where it expanded during the Late Glacial into its current Holocene "warm period" refugia. This colonisation history has led to the distinct East–West structure of five genetic clusters. The two main genetic lineages likely derived from ancient divergence during an interglacial or interstadial. The respective contact zone (Brenner line) matches a main biogeographic break in the European Alps also found in herbaceous alpine plant species.</span></p>
Data from: Three newly described species of Ziziphus from Maharashtra, India based on morphological and molecular evidence
<p>Three new species of <em>Ziziphus</em> (Rhamnaceae) from Maharashtra, India, <em>Z. bhandarii</em> Gholave & S.P.Gaikwad, <em>Z. naikii</em> Gholave & S.P.Gaikwad, and <em>Z. bhansalii</em> Gholave & S.P.Gaikwad are described here. These species occur in isolated fragments of the Deccan thorn scrub forest ecoregion on the Deccan plateau. Their placement in <em>Ziziphus</em> is confirmed by molecular analyses combining ITS and <em>trnL-F</em> regions. Given this phylogeny is the most robust to date of <em>Ziziphus</em>, a previously proposed intrageneric classification was tested, and the classification was not supported suggesting a need for additional investigations in this genus. The new species are most closely related to three Indian species, <em>Z. horrida</em> Roth, <em>Z. xylopyrus</em> (Retz.) Willd., and <em>Z. caracutta</em> Buch.-Ham. ex Roxb, respectively, which are morphologically similar and sympatric, and are distinguishable from known species based on several vegetative and reproductive characteristics presented here. A diagnostic key to the <em>Ziziphus</em> species known to occur in Maharashtra is provided.</p>
