Building bridges between environmental and political agendas is essential nowadays in face of the increasing human pressure on natural environments, including wetlands. Wetlands provide critical ecosystem services for humanity can generate a considerable direct or indirect income to local communities. To meet many sustainable development goals, we need move our trajectory from current destructive wiser wetland use. The article contain proposed agenda Pantanal aiming improvement public policy...
Bromeliaceae is a morphologically distinctive and ecologically diverse family originating in the New World. Three centers of diversity, 58 genera, about 3,140 bromeliad species are currently recognized. We compiled all studies related to reproductive biology, genetic population structure Bromeliaceae, discuss evolution conservation this family. Bromeliads preferentially pollinated by vertebrates show marked variation breeding systems, from predominant inbreeding outcrossing, as well...
Genetic diversity and population structure in plants are directly associated with the reproductive system gene flow by pollen seeds. We examined system, pollination biology, genetic structure, Bromelia hieronymi, an endemic species of humid Brazilian chaco. characterized hand-pollination experiments biology observations, both situ. For analysis we used nuclear plastid microsatellite markers. hieronymi is allogamous, self-incompatible clonal. The potential pollinators were hawkmoths...
Abstract The Brazilian region of Mato Grosso do Sul state, harbours a mosaic vegetation and ecotones, being an environmentally heterogeneous area that includes different biomes alongside various geological formations. In addition to conducive diversification processes, this provides ideal habitat for Dyckia. We used genetic diversity phylogeographic approaches gain insights into the process five narrow-range plus one widespread Dyckia species endemic such particular region. For that, we...
Seed dispersal, population structure and the mating system of plant species can have great consequences on genetic populations. Vriesea gigantea is a bromeliad from southeastern Brazil which self-compatible pollinator dependent for fruit set. Its populations are fertile in terms production flowers, pollen, fruits seeds. To assess importance seed supply gene flow, colonization distribution adult individuals, dispersal V. were studied. Seeds dispersed over short distances; most seeds land...
The patterns of genetic structure in plant populations are mainly related to the species life history and breeding system, knowledge these is necessary for management, use, conservation biological diversity. Polyploidy considered an important mode evolution plants, but few studies have evaluated polyploid populations. We studied morphological variation Bromelia antiacantha (Bromeliaceae) populations, a terrestrial species. •Microsatellite markers analyses were used explore diversity wild B....
Plant fertility is a central subject of many questions in plant evolutionary and conservation biology. Pollen availability, abiotic resources, flowering pattern can limit fruit seed production. Open pollination pollen supplementation studies are used to estimate any limitation natural populations. To study the impact these factors on reproductive success Vriesea gigantea , an epiphytic bromeliad Atlantic Rainforest Brazil, its four populations Itapuã State Park was assessed by considering...
The mating system is an important component of the complex set reproductive isolation barriers causing plant speciation. However, empirical evidence showing that may promote in co-occurring species limited. mechanisms by which can act as a barrier are also largely unknown.Here we studied progeny arrays genotyped with microsatellites and patterns stigma-anther separation (herkogamy) to understand role shifts promoting between two hybridizing taxa porous genomes, Pitcairnia albiflos P....
Abstract Eight microsatellite markers were isolated from Pitcairnia albiflos , an endangered endemic bromeliad species restricted to ‘inselberg’ rock outcrops in the state of Rio de Janeiro, Brazil. The number alleles observed for each locus ranged two 12. Average and expected heterozygosities 0.408 0.663, respectively. cross‐amplification test 16 taxa suggests that will be useful numerous related species. loci used study genetic structure reproductive biology fragmented inselberg...
Metabolomics strategies are important tools to get holistic chemical information from a system, but they scarcely applied endophytic fungi understand their profiles of biosynthesized metabolites. Here Penicillium sp. was cultured using One Strain Many Compounds (OSMAC) conditions as model system demonstrate how this strategy can help in understanding metabolic and determining bioactive metabolites with the application metabolomics statistical analyses, well molecular networking. fermented...
Abstract Cotton is socially and economically important worldwide. Notably, research on eco-friendly technologies that increase the sustainability of this production system increasing. We explored potential bacterial strains isolated from cotton roots to promote plant growth. Bacteria were by using a pasteurization method cultivated nutrient agar for strain purification selection. The subjected in vitro tests verify their ability solubilize calcium phosphate, producing indole-3-acid acetic,...
Abstract Reproductive biology and plant fertility are directly related to many aspects of evolution conservation biology. Vriesea friburgensis is an epiphytic terrestrial bromeliad endemic the Brazilian Atlantic rainforest. Hand‐pollination experiments were used examine reproductive system in a wild population V. . Plant was assigned considering flower production, fruit seed set, germination, pollen viability. Self‐sterility observed from spontaneous selfing manual self‐pollination...
Abstract Plant fertility can influence many aspects of population ecology and evolution. The quantity quality pollen produced by a plant is an important component reproductive success. was analyzed assessing: chromosome number, meiotic behavior viability seven native populations Vriesea gigantea . All plants presented 2n = 50 chromosomes. Most the mother cells showed regular with 25 bivalents segregation. In accordance, high (84–98%) recorded for all investigated populations. These results...
Abstract Dyckia is the third most diverse genus from Pitcairnoideae , pollinated mainly by insects and hummingbirds. In this study, we evaluated demography, reproductive biology pollination of excelsa a saxicolous species typical ironstone outcrops. It occurs in groupings composed genets, ramets seedlings bloomed several times, principally September, with fruiting dispersing seeds November. The anthesis diurnal flowers remain open for 2 days. Nectar volume decreased during anthesis, whereas...
Microsatellite markers were isolated in Dyckia distachya, an endangered bromeliad from southern Brazil, which will be useful to assess the population genetic structure and reproductive success introduced natural populations of this species. Twenty microsatellite loci developed enriched genomic library, nine these amplified. The characterized 43 individuals wild D. distachya populations. All polymorphic, with four ten alleles per locus. In observed expected heterozygosities ranged 0.136–0.667...
Abstract In this contribution the rediscovery of bromeliad Dyckia excelsa in Mato Grosso do Sul state, central-western Brazil, is reported. This species was first described based on a single individual from particular collection 1993 with no precise locality. Illustrations and brief discussion leaf anatomy are provided. One additional species, gracilis, which has been overlooked by previous authors, included list Bromeliaceae State. An updated key for region D. presented. The status State,...
Inbreeding depression is a reduction of fitness in the progeny closely related individuals and its effects are assigned to selfing or biparental inbreeding. Vriesea gigantea self-compatible bromeliad species distributed Brazilian Atlantic rainforest habitat destruction fragmentation collection have decreased natural populations. We aim describe occurrence inbreeding (δ) three populations V. correlate this phenomenon with previous studies fertility, genetic diversity, population structure,...
A checklist of 11 genera and 41 species Bromeliaceae occurring in the state Mato Grosso do Sul (MS) is presented. Of total number species, five are endemic belong to Dyckia Tillandsia. The subfamily Pitcairnioideae richest including taxa that rare Brazil (Deuterocohnia Fosterella). Tillandsioideae plus one infraspecific taxon; however, it only represented by Tillandsia, most widely distributed all over and/or nearby countries.
