The network structure of plant-arbuscular mycorrhizal fungi.
TLDR
The plant-AMF interaction pattern is interpreted in the context of how plant- AMF associations can be underlying mechanisms shaping plant community assemblages, and both plants and AMF show a nested structure, although AMFs have lower nestedness than plants.
Late Cretaceous–Early Eocene origin of yams (Dioscorea, Dioscoreaceae) in the Laurasian Palaearctic and their subsequent Oligocene–Miocene diversification
TLDR
Fossil records from both the Northern and Southern Hemispheres were used to test hypotheses about the origin of the genus Dioscorea, and to examine potential macroevolutionary processes that led to its current distribution.
Allozyme and chloroplast DNA variation in island and mainland populations of the rare Spanish endemic, Silene hifacensis (Caryophyllaceae)
TLDR
The geographical distribution of allozymes and cpDNAhaplotypes is discussed in terms of population history, dispersal and, speculatively, in termsof the possibility that there has beenocumented translocation of material betweenpopulations.
BURNING PHYLOGENIES: FIRE, MOLECULAR EVOLUTIONARY RATES, AND DIVERSIFICATION
TLDR
It is found that seeders had neither higher molecular rates nor higher diversification than resprouters, which means that fire acting as a throttle for diversification is by no means the rule in fire-prone ecosystems.
On the verge of extinction: genetics of the critically endangered Iberian plant species, Borderea chouardii (Dioscoreaceae) and implications for conservation management
TLDR
Genetic diversity and population structure have been investigated through the analysis of neutral hypervariable markers such as simple sequence repeats (SSRs) and randomly amplified polymorphic DNAs (RAPDs) to unravel the impact of life history traits in the differentiation of the two subpopulations.
The fewer and the better: prioritization of populations for conservation under limited resources, a genetic study with Borderea pyrenaica (Dioscoreaceae) in the Pyrenean National Park
TLDR
Genetic structuring of populations and representativity values derived from regression analyses of probabilities of loss of rare alleles together support differentiation of the B. pyrenaica populations into different management units.
Two approaches for the selection of Relevant Genetic Units for Conservation in the narrow European endemic steppe plant Boleum asperum (Brassicaceae)
TLDR
A combination of two methods based on population genetic structure estimators and on probabilities of loss of rare alleles to identify the Relevant Genetic Units for Conservation (RGUCs) of the endemic steppe plant B. asperum.
Secondary compounds enhance flammability in a Mediterranean plant
TLDR
The results suggest that the capacity to produce and store terpenes can be considered a flammability-enhancing trait and could have an adaptive value in fire-prone ecosystems.
In vitro micropropagation of rare and endangered moss Entosthodon hungaricus (Funariaceae) = Micropropagação in vitro do musgo raro Entosthodon hungaricus, ameaçado de extinção (Funariaceae)
TLDR
The first axenical culture of E. hungaricus was successfully established, the first in vitro micropropagation of this rare and endangered species was achieved, and the study contributes to the conservation biology and for the potential use of this moss species in biotechnological research.
