The gastropod fauna of Bushehr Province intertidal zone at the Persian Gulf were identified following an investigation starting spring 2009 until winter 2011. Bushehr coastline is a 673.62 km stretch along the northern and northeastern coast of the Persian Gulf. Sampling took place from Deylam at Bushehr-Khuzestan borderlines, extending southeastward through Genaveh, Bushehr, Bolkheyr, Kab...

The Ruyang (Mesoproterozoic; Pt2) and Luoyu (Neoproterozoic; Pt3) groups in the southern North China Platform are dominated by peritidal siliciclastic rocks and contain abundant microbially induced sedimentary structures (MISS), including multidirected and mat-protected ripple marks, mat chips, mat-smoothed ripple marks, various sand cracks, and irregular growth ridges. These MISS can be groupe...

Recent reports have presented meta-analyses of global biological impacts of climate change (1, 2). However, there is debate as to the level of confidence ascribed to the certainty that global climate change has caused the observed biological changes (3). Two important considerations in the assessment of how climate change will impact organisms are (i) how close organisms are to their thermal li...

There is mounting evidence that parasites can influence the composition and structure of natural animal communities. In spite of this, it is difficult to assess just how important parasitism is for community structure because very few studies have been designed specifically to address the role of parasites at the community level, no doubt because it is difficult to manipulate the abundance of p...

Here, we report a draft 5.58-Mb genome sequence of Pseudoalteromonas sp. strain R3, isolated from an intertidal-zone sludge sample, which has l-amino acid oxidase activity. The genomics information of this strain will facilitate the study of l-amino acid oxidase, quorum sensing, and the relationship of the two.

Animals with habitats in the intertidal zone often display biological rhythms that coordinate with both the tidal and the daily environmental cycles. Two recent studies show that the molecular components of the biological clocks mediating tidal rhythms are likely different from the phylogenetically conserved components that mediate circadian (daily) rhythms.
