Mosses have often been used for biomonitoring because of their diversity habitats, structural simplicity, and rapid multiplication rate. This research aimed to study the tolerance heavy metal in 3 species terricolous mosses i.e., Barbula consanguinea, Hyophila apiculata, H. involuta. The gametophores were immersed at 4 concentrations each metals Cd, Pb, Zn as well controls with no metal. After ...

Karyotypic diversity is critical to catalyzing change in the evolution of all plants. By resulting meiotic incompatibility among sets homologous chromosomes, polyploidy and aneuploidy may facilitate reproductive isolation potential for speciation. Across plants, karyotypic variants form allopolyploids receive greater taxonomic attention relative autopolyploids aneuploids. In particular, prevale...

Biological soil crusts (BSC) are associations among cyanobacteria, green algae, lichens, mosses and particles, which contribute to multiple ecosystem functions such as nitrogen fixation stabilization. The present work aims evaluate propagation conditions of different functional types BSC (dominated by cyanolichens, phycolichens mosses) potentially useful for the recovery degraded soils. In gree...

Let us know how access to this document benefits you. Abstract Mosses display a number of hallmark life history traits that influence their ecology at the population and community level. The long lived separation of sexes observed in the haploid gametophyte (dioicy) is one such feature of particular importance, as it is observed in the majority of bryophytes and creates intraspecific specializa...

The metropolitan area of the Toluca Valley (MATV) extends over an area of 1208.55 km(2) and has 1,361,500 inhabitants making it the fifth highest populated area in the country and the second highest in the state. The MATV has several environmental problems, with regards to the air quality. Particles PM10 and PM2.5 are considered to be the main pollutant due to these particles frequently exceedi...

Stomatal pores evolved more than 410 million years ago [1, 2] and allowed vascular plants to regulate transpirational water loss during the uptake of CO(2) for photosynthesis [3]. Here, we show that stomata on the sporophytes of the moss Physcomitrella patens [2] respond to environmental signals in a similar way to those of flowering plants [4] and that a homolog of a key signaling component in...

PREMISE OF THE STUDY Mosses, very diverse in modern ecosystems, are currently underrepresented in the fossil record. For the pre-Cenozoic, fossil mosses are known almost exclusively from compression fossils, while anatomical preservation, which is much more taxonomically informative, is rare. The Lower Cretaceous of Vancouver Island (British Columbia, Canada) hosts a diverse anatomically preser...

Mosses are an understudied group of plants that can potentially confirm or expand principles of plant function described for tracheophytes, from which they diverge strongly in structure. We quantified 35 physiological and morphological traits from cell-, leaf- and canopy-level, for 10 ground-, trunk- and branch-dwelling Hawaiian species. We hypothesized that trait values would reflect the disti...

Vascular plants serve as target species for the evaluation of restoration success as they account for most of the plant species diversity and vegetation cover. Although bryophytes contribute considerably to the species diversity of meadows, they are rarely addressed in restoration projects. This project is a first step toward making recommendations for including mosses in alluvial floodplain re...

Background Molecular phylogeny has resolved the liverworts as the earliest-divergent clade of land plants and mosses as the sister group to hornworts plus tracheophytes, with alternative topologies resolving the hornworts as sister to mosses plus tracheophytes less well supported. The tracheophytes plus fossil plants putatively lacking lignified vascular tissue form the polysporangiophyte clade...
