BioTIME: A database of biodiversity time series for the Anthropocene.

Motivation: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series.

A new species of Diadumene (Actiniaria: Diadumenidae) from the subtropical coast of Brazil.

Diadumene paranaensis n. sp., collected from the Yacht Club of Paranaguá (Paranaguá Bay, Paraná State, southern Brazil), is described as a new species of sea anemone, based on external and internal morphology, cnidome, and molecular data for 16S/CO3 mitochondrial DNA.

A new species of Pachycerianthus (Cnidaria, Anthozoa, Ceriantharia) from Tropical Southwestern Atlantic.

A new species of Pachycerianthus (Cnidaria: Ceriantharia) is described from the Brazilian coast of the southwestern Atlantic Ocean. Pachycerianthus schlenzae sp. nov.

An outbreak of Portuguese man-of-war (Physalia physalis - Linnaeus, 1758) envenoming in Southeastern Brazil.

Introduction: Portuguese man-of-war, Physalia physalis (Linnaeus, 1758), are cnidarians capable of discharging intracellular organelles filled with venom, resulting in severe envenomation in humans.

Methods: We report the clinical and therapeutic aspects of 331 accidents involving Portuguese man-of-war in an outbreak on the coast of the State of São Paulo, Brazil.

Results: The clinical manifestations of envenomation were rare and mild and mostly local, systemic reactions; there was a low rate of late complications.

Evolutionary diversification of banded tube-dwelling anemones (Cnidaria; Ceriantharia; Isarachnanthus) in the Atlantic Ocean.

The use of molecular data for species delimitation in Anthozoa is still a very delicate issue. This is probably due to the low genetic variation found among the molecular markers (primarily mitochondrial) commonly used for Anthozoa. Ceriantharia is an anthozoan group that has not been tested for genetic divergence at the species level.

Skin lesions in envenoming by cnidarians (Portuguese man-of-war and jellyfish): etiology and severity of accidents on the Brazilian coast.

This work attempts to establish dermatological identification patterns for Brazilian cnidarian species and a probable correlation with envenoming severity. In an observational prospective study, one hundred and twenty-eight patients from the North Coast region of São Paulo State, Brazil were seen between 2002 and 2008. About 80% of these showed only local effects (erythema, edema, and pain) with small, less than 20 cm, oval or round skin marks and impressions from small tentacles.

[Occurrence of Cryptosporidium spp. in a dairy cattle herd from Caçapava Municipality, São Paulo State, Brazil].

Occurrence of Cryptosporidium spp. was investigated in a Brazilian dairy farm over the course of 1 year. Cattle of different aged were employed and divided into seven groups: 0-2 months; 2-4 months; 4-6 months; 6- 10 months; 10-16 months; 16-24 months; > 24 months.

Genetic variation and population structuring in two brooding coral species (Siderastrea stellata and Siderastrea radians) from Brazil.

Siderastrea stellata and S. radians are scleractinian coral species that present a remarkable overlap of diagnostic characteristics and sympatric distribution. Moreover, both are viviparous with similar reproductive strategies and with a gregarious larval behavior.

A report of 49 cases of cnidarian envenoming from southeastern Brazilian coastal waters.

Forty-nine accidents caused by jellyfish (Cnidaria) were observed during a period of 5 years on the southeastern coast of Brazil. Most of them involved male patients (65.3%), the injured areas being mainly the legs (71.
