The birth and death of toxins with distinct functions: a case study in the sea anemone Nematostella.

Molecular biology and evolution, 2019
The cnidarian Nematostella vectensis has become an established lab model, providing unique opportunities for venom evolution research. The Nematostella venom system is multimodal: involving both nematocytes and ectodermal gland cells, which produce a ...

Predicting protein decomposition: the case of aspartic-acid racemization kinetics [PDF]

, 1999
The increase in proportion of the non-biological (D-) isomer of aspartic acid (Asp) relative to the L- isomer has been widely used in archaeology and geochemistry as a tool for dating. The method has proved controversial, particularly when used for bones.

Functions of Bidirectional Sex Change and Simultaneously Hermaphroditic Phase Gonads in the Monogamous Goby Lubricogobius exiguus

Ethology, EarlyView.
Many fishes can change their sex. The remarkable example, Lubricogobius exiguus, is a goby that can undergo bidirectional sex change with hermaphroditic gonads, containing both developed ovaries and testes (simultaneously hermaphroditic phase gonad). Based on field observations, we demonstrate that the goby experiences frequent social changes, such as ...

On the Nematocysts of Sea Anemones [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1929
The main object of this paper has been to determine whether or no it is possible to differentiate the species and genera of Actinians by employing as criteria the characteristics of their nematocysts.

The Kunitz-Type Protein ShPI-1 Inhibits Serine Proteases and Voltage-Gated Potassium Channels

Toxins, 2016
The bovine pancreatic trypsin inhibitor (BPTI)-Kunitz-type protein ShPI-1 (UniProt: P31713) is the major protease inhibitor from the sea anemone Stichodactyla helianthus.

Signatures of Interchange Reconnection: STEREO, ACE and Hinode Observations Combined [PDF]

, 2009
Combining STEREO, ACE and Hinode observations has presented an opportunity to follow a filament eruption and coronal mass ejection (CME) on the 17th of October 2007 from an active region (AR) inside a coronal hole (CH) into the heliosphere.

Between the Poles: Rethinking Global Patterns in Sea Anemone Biodiversity

Journal of Biogeography, EarlyView.
ABSTRACT Aim To assess global sampling coverage of sea anemones and global species richness across four different spatial resolutions, and analyse these along latitudinal gradients to investigate true bimodality and the extent to which these patterns have been influenced by uneven sampling efforts. Location The study encompasses a global scale.

British Sea Anemones [PDF]

Nature, 1929
WHILST in some branches of science, especially physics, there are so many workers in the field that monographs can be continually revised, in others many years must pass by before an expert can bring our knowledge up-to-date. Dr. T. A. Stephenson, one of the two leading workers on anemones at the present time, is to be congratulated on his effort to ...

Disturbance-effect relationships applied in an integral Ecological Risk Analysis for the human use of the North Sea [PDF]

, 2009
The relationship between the intensity of seven types of human based disturbances and their resulting effects on survival and reproduction of 30+ species were described as a function of increased mortality or reduced reproduction in the report of Jak et ...

Novel behavioural assays reveal sex‐specific behavioural syndromes in anemonefish

Journal of Fish Biology, EarlyView.
Abstract Individual differences in behaviour and behavioural plasticity have been extensively studied in a variety of animals across the phylogenetic spectrum. Amphiprion species bring distinct insight into the topic because of their unique life history, mating system, and extraordinary degree of behavioural plasticity associated with protandrous (male‐
