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...
The Pantanal is characterised by a diversity of environments with areas ranging from periodic or permanent heavy flooding to low flood levels, and even that never flood. Plant species which inhabit the floodplain are distributed in specific niches, influence various phytogeographic domains, including Seasonal Semi-deciduous Forest, Amazon Rainforest, Cerrado Chaco, as well rocky remnants, wide ecological span their components. In intensely flooded areas, aquatic macrophytes widely...
This paper proposes a new interpretation for primary thickening in monocotyledons. The anatomy of the vegetative organs following species was examined: Cephalostemon riedelianus (Rapataceae), Cyperus papyrus (Cyperaceae), Lagenocarpus rigidus, L. junciformis Echinodorus paniculatus (Alismataceae) and Zingiber officinale (Zingiberaceae). endodermis with meristematic activity observed root all species, stem Cyperus, Cephalostemum leaf trace Echinodorus. Considering continuity tissues through...
Seed shape, dimensions, surface texture, sculpture, hilum and position were recorded for five Aeschynomene L. species (Fabaceae): A. denticulata, fluminensis, histrix, rudis, sensitiva from Pantanal, Brazil, using a scanning electron microscope. The shared similar seed characteristics such as color, surface, apex base, face side, hilar fissure, sculpture aril micropylar pore position, testa sculpture. differed in measurements (seed length width, elevation). exhibited the microsculpture,...
The tree-shrub species Pouteria glomerata (Miq.) Radlk. (Sapotaceae) occurs in periodically flooded areas marked by periods of drought. It has the potential for use ecological restoration riparian forests; however, seed germination strategies were not fully understood. In this study, we aimed to evaluate morphology, anatomy, and physiological aspects identify possible factors related low germination. morphoanatomical analysis was assessed according routine procedures. For assessment,...
O presente estudo teve como objetivos descrever a riqueza e diversidade em espécies analisar os aspectos fitossociológicos de um trecho da mata ciliar do rio Prata, localizado na Fazenda Nossa Senhora Aparecida no município Jardim, MS. Seis transectos 150 m cada foram distribuídos aleatoriamente perpendiculares à margem subdivididos 90 parcelas 10 m×10 m. Em parcela amostrados todos indivíduos com diâmetro 1,30 altura solo (DAP) > 3,18 cm, totalizando 661 pertencentes 33 famílias, 57...
Studies on Neotropical aquatic macrophytes have increased in recent decades, however species richness wetlands of South America is far from being fully known. In addition, studies having an ecological approach are scarce the Pantanal. Rapid assessments essential for gaining knowledge biodiversity region. This study was performed five sites Baía do Castelo, western border Brazilian Pantanal, which included wild-rice patches, floating mats and meadows. At each site, plots 0.5 × m were set (n =...
The goal of this study was to compare the vegetation structure macrophytes in an anabranch-lake system. Sampling carried out at flood three types aquatic vegetation, (wild-rice, floating meadow and Polygonumbank) anabranch Bonfim (lotic) lake Mandioré (lentic) plots along transects, estimate percent coverage record life forms species. We collected 59 species 50 genera 28 families. Fabaceae Poaceae were most representative emergent plants predominated (62%). In anabranch, with 48 species,...
We present the leaf anatomy of seven amphibious species Aeschynomene L. (Papilionoideae, Leguminosae), interpreting their structures and ecological functions, also, providing information on which taxonomy can be based, especially morphologically similar species. evaluated americana, A. ciliata, evenia, denticulata, fluminensis, rudis sensitiva. The corroborates separation series Americanae, Fluminenses, Indicae Sensitivae, with shape petiole, types trichomes quantity vascular units in...
The phenology of macrophytes in response to environmental stressing factors is easily evidenced wetlands under seasonal floods, such as the Pantanal. In these environments, survival and establishment seedlings aquatic plants are restricted, limited episodes with presence water, resulting posterior sexual propagation for dispersal seeds adapted hydrochory, overcoming dry period dormant sediment. We described reproductive macrophyte community relation phases flooding between species life...
After synonymization of Araujia and Morrenia (Asclepiadoideae, Apocynaceae), there are 12 spp., with the Chaco region, including Argentina, Bolivia, Brazil Paraguay, as their centre diversity. If recognized independently, neither genus is monophyletic, but consensus on this circumscription remains unclear. Therefore, to improve our understanding taxonomy relationships, research aimed (1) find new characters based leaf morphology anatomy (2) investigate how these distributed in most recent...
To minimize the effects of abiotic factors in aquatic systems, plants feature efficient anatomical structures which are essential for successful colonization. The macrophytes show great plasticity vegetative organ development, and such reflects environmental changes. Specifically, since Nymphaea gardneriana can inhabit completely different environments, featuring fully submerged leaves rivers floating lakes, this work aimed to compare anatomy these two kinds leaves. Submerged reddish with a...
This study aimed to characterize and compare the stem root anatomy of Echinopsi calochloraand E. rhodotricha (Cactaceae) occurring in Central–Western Region Brazil, Mato Grosso do Sul State. Three individuals each species were collected, fixed, stored prepared following usual techniques, for observation light scanning electronic microscopy. All revealed uniseriated epidermis, thick cuticle, parallelocytic stomata at epidermis level, well-developed hypodermis. Cortical medullary bundles are...
In flood-driven environments the life cycles of organisms are regulated in function water regime. The objective this work is to analyse phenophases flowering and fructification two species amphibious aquatic macrophytes, Polygonum hispidum Kunth P. punctatum Elliott, with regard flooding cycle Brazilian Pantanal. We collected monthly data 26 plots 20 ponds during years. phases were classified as drought, rising, flood, receding. periods an abundance (rising, flooding, receding) most...
Our objective was to inventory the flora of aquatic macrophytes and their life forms, determine species similarity in different water bodies. Sampling vegetation carried out 333 plots 0.5 x m along ten transect lines on a boat best cover studied areas. Poaceae (18.9%), Cyperaceae (9.4%), Fabaceae, Onagraceae, Pontederiaceae (7.5% each) were most represented families. Emergent (56.6%), free floating (20.8%), rooted amphibious (13.2%) common forms. We observed dissimilarity between sampled...
Resumo Neste estudo é descrita a composição florística e analisada influência do pulso de inundação sobre biomassa quatro espécies macrófitas aquáticas, Eichhomia azurea, E. crassipes, Pistia stratiotes Salvinia auriculata, ao longo um ciclo hidrológico, em uma lagoa meandro no Pantanal Mato Grosso Sul.

Abstract Phylogenetic analyses of early-diverging Faboideae have indicated that genera previously positioned in distinct tribes are instead closely related, e.g. the Amburaneae clade, and relatively recent rearrangements many into clades has hampered identification morphological synapomorphies for unrecognized clades. Our aims to evaluate anatomical vegetative characters leaflets attached reproductive features identify new clade subclades, supporting intergeneric relationships diagnostic...
Nymphaea has seven species already catalogued in the flood prone areas of Brazilian Pantanal. However, some remain difficult to identify and descriptions anatomy vegetative organs are an important tool for infrageneric separation aid group taxonomy. The collected Pantanal prepared according usual techniques anatomical studies showed similar structural characteristics, data on arrangement vascular bundles midrib petiole, as well form distribution sclereids, were consistent. oxypetala stands...
