Cyperus prophyllatus, an endangered new species of Cyperus (Cyperaceae) from an aquatic ecosystem of the Atlantic Forest, Espírito Santo State, southeastern Brazil, is described and illustrated. The spikelet morphology of Cyperus prophyllatus is unique among the c. 950 species of Cyperus in having both a conspicuous spikelet prophyll and a corky ra...

Global patterns of species and evolutionary diversity in plants are primarily determined by a temperature gradient, but precipitation gradients may be more important within the tropics, where plant species richness is positively associated with the amount of rainfall. The impact of precipitation on the distribution of evolutionary diversity, howeve...

List of 2,025 tree community surveys used in this study with their respective metadata, including sources, genus and species richness, lineage diversity (standardised effect size of phylogenetic diversity), climatic variables, protection status, and loss of native area over the last 30 years in the municipality where these communities occur.

List of angiosperm clades (nodes) used to date the phylogeny via fossil-derived calibrations, taxa assigned as a reference for fossil placement, minimum age used as offset, mean age of the clades, and their respective sources. Ages in myrs.

List of 1,100 angiosperm genera used in the phylogenetic reconstructions, their respective sources of rbcL and matK sequences, GenBank accession numbers, when applicable; collectors, collector numbers and herbaria where vouchers were deposited, when applicable. RBG = Royal Botanic Garden Edinburgh. Asterisk indicates the 852 genera used in the comm...

Mineral soils are usually considered inappropriate for pollen analysis because of the poor quality of pollen and spore preservation and the disturbed stratigraphy. However, here we present a 57 cm core, collected from a waterlogged sandy soil in the lowland Atlantic Forest of SE Brazil, which shows good stratigraphy and good preservation of pollen...

Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vas...

Mansoa minensis M.M.Silva-Castro is reported for the first time for the state of Espírito Santo, Brazil. We provide an updated description, comparisons with closely related species, and suggest a revised conservation status for this species. We also present an identification key for all species of Mansoa that occur in Espírito Santo.

Since its description, almost 100 years ago, the genus Dinizia has been treated as monospecific, comprising the single canopy-emergent species Dinizia excelsa Ducke which grows in non-flooded Amazonian forests of Guyana, Suriname and seven states of northern and central-western Brazil. Dinizia jueirana-facao G. P. Lewis & G. S. Siqueira, which grow...

Simira robusta (Rubiaceae), a new species from the Atlantic Rainforest of the Espírito Santo state, south-eastern Brazil, is here described and illustrated, and compared with similar species. It most resembles S. grazielae, from which it differs by the larger inflorescences, antrorse pubescent flowers and fruits, and by its larger fruits. Its habit...

This paper provides the first record of Eschweilera compressa (Lecythidaceae) in Espírito Santo state,Brazil. According to IUCN criteria and the Brazilian government,this species is assigned as Critically Endangered globally and Endangered nationally,respectively. Herein,E. compressa is regionally assigned as Critically Endangered in Espírito Santo...

Lecythis marcgraaviana (Lecythidaceae), a species previously placed in synonymy of L. pisonis, is resurrected and described in detail for the first time. A neotype, discussion of the history of this species, taxonomic notes, images, and an identification key to the species of the Lecythis pisonis clade from eastern Brazil are provided. This tree or...

Estudos paleoambientais desde ~50.000 anos na costa do Brasil e, em particular, no litoral do Espírito Santo, são ainda insuficientes para servir de base a reconstituições da dinâmica da vegetação, de oscilações do nível relativo do mar e de flutuações climáticas e respectivas influências sobre a ação humana milenar. Para obter essas informações, u...

Interdisciplinary palaeoenvironmental studies in the late Quaternary on the Brazilian coast and, in particular, on the Espirito Santo coast, Southeastern region, are still insufficient to serve as a basis for the reconstruction of the dynamics of vegetation, of relative sea level oscillations and climatic fluctuations and their respective influence...

Some of the modern patterns found in the Neotropical biodiversity may have been influenced by processes related with climatic changes during the late Quaternary. The Atlantic Rainforest in the States of Espírito Santo and Bahia presents modern characteristics that may be related with such historical events, like the centers of endemism and the occu...

A sediment core was studied to characterize the influences of Holocene sea-level variations in the Barra Seca River valley, in the Atlantic rainforest, Linhares, Espírito Santo, southeastern Brazil. Biological proxies (pollen, spores, and sponge spicules), 14 C dating, granulometry,  13 C,  15 N, C/N and major chemical elements revealed the estab...

Analysis of biological proxies in lake sediment and geochemical analysis of soil profiles reveal natural vege-tation dynamics, with climate inferences, since the late Pleistocene in a fragment of the pristine lowland Atlantic Forest of southeastern Brazil. Carbon isotopes from soil organic matter and 14 C ages from the humin fraction indicate the d...

We present 25 records of sightings, feathers and nests of the Harpy Eagle Harpia harpyja in the last 27 years and also the first detailed description of a nest of a Harpy Eagle in the Brazilian Atlantic Forest, found at the “Reserva Natural Vale” (RNV), Linhares, Espírito Santo, Brazil. Most Harpy Eagle records were obtained along the RNV roads by...
