Spatial and temporal variation of community composition and species cover following dune restoration in the Devesa de Albufera (Valencia, Spain).
2015
Plant populations were reintroduced to the coastal dune bar of the Devesa de Albufera from 1988 to 2004; different coastline sections received different species composition and cover. With the aim to detect spatial and temporal variation of floristic diversity, we compared current species composition and cover across the length of the Devesa and across the dune bar with those imposed at the time of restoration. Non-metric multidimensional scaling (NMDS) detected significant differences both across the dune faces and across the coast sections. Differences across the dune faces reflect the sea-inland ecological gradient and resulted from a spatial rearrangement of plant populations: Calystegi…
What do leaf anatomy and micromorphology tell us about the psammophilous Pancratium maritimum (Amaryllidaceae) in response to sand dune conditions?
2015
Abstract The present study aimed at verifying the morphological variation in leaf traits among different populations of Pancratium maritimum (sea daffodil) and the correlation between leaf diversity and climate conditions at different sites. Eleven populations of P. maritimum from Mediterranean coastal sand dunes were investigated with respect to leaf surface micro-morphology, leaf anatomy, and vascular pattern. Morphometric analysis was based on 29 quantitative foliar parameters. One-way analysis of variance (ANOVA), principal component analysis (PCA), discriminant function analysis (DFA), and clustering by Ward’s method were used for the statistical evaluation. Results revealed a rather u…
Endosphere microbial community assemblage of an inland sand dune colonizing plant
2016
Plant-associated microbes could play a role in plant colonization of sand dune ecosystems, but microbes associated with plants colonizing those ecosystems in the arctic are poorly known. I characterized Deschampsia flexuosa-associated microbiomes in two successional stages (early and late) of arctic inland sand dune differ in their plant species richness and soil physiochemical properties. The work based on culturable microbes showed that different plant parts harbour generalist and specific groups of endosphere microbes and most of the endosphere bacteria were closely related to other cold habitat microbes. Also, most of the endosphere bacteria possessed an important plant growth promoting…

Macrobiotus naginae sp. nov., a New Xerophilous Tardigrade Species from Rokua Sand Dunes (Finland)
2022
Animals that colonize soil show specific adaptations to soil. Compared to closely related species living on the surface, the limbs of soil-dwelling animals are often shortened, reduced, or absent to allow a less restricted passage through cavities between soil particles. This pattern of limb reduction has also been observed in tardigrades, where multiple lineages that colonized the below-ground habitat show independent reduction and/or loss of legs and claws. In the tardigrade superfamily Macrobiotoidea, leg and claw reductions are a common trait found in the Macrobiotus pseudohufelandi complex. This rarely found species complex currently contains four nominal taxa. Here we describe, with t…
The role of symbiotic arbuscular mycorrhizal fungi (Glomeromycota) in roots of the host plant Deschampsia flexuosa in vegetation succession of inland…

Suurin osa maalla elävistä putkilokasvilajeista ja -heimoista elää symbioosissa mykorritsasienten kanssa. Mykorritsatyyppejä on useita, ja näistä yleisin ja vanhin on arbuskelimykorritsasymbioosi, jossa Glomeromycota-sienet muodostavat arbuskelimykorritsaa (AM) kasvien juurien sisällä. Tämä kasvin ja sienen välinen tiivis suhde on molempia osapuolia hyödyttävä symbioosi. Toisenvarainen AM sieni on riippuvainen kasvin tuottamasta orgaanisesta hiilestä, ja vastapalveluksena sieni voi parantaa kasvin ravinteiden- ja vedenottokykyä, sekä suojata tätä taudinaiheuttajilta, tuhohyönteisiltä ja laiduntajilta, sekä parantaa kasvin kuivuudensietokykyä. Vaikuttamalla isäntäkasvien kasvuun ja resurssie…
