Summary The evolution of green plants from aquatic to terrestrial environments is thought to have been facilitated by the acquisition of gametangia, specialized multicellular organs housing gametes. Antheridia and archegonia, responsible for producing and protecting sperm and egg cells, undergo formative cell divisions to produce a cell to ...

Positive species interactions structure rhodolith bed communities at a global scale
ABSTRACT Rhodolith beds are diverse and globally distributed habitats. Nonetheless, the role of rhodoliths in structuring the associated species community through a hierarchy of positive interactions is yet to be recognised. In this review, we provide evidence that rhodoliths can function as foundation species of multi‐level facilitation cascades and ...

The taxonomic status of the genus Stylactaria Stechow, 1921 (Hydroidomedusae, Anthomedusae, Hydractiniidae), with the description of a new species [PDF]
The status of all the species ascribed in the literature to Stylactaria is discussed, that nominal genus is considered a congener of Hydractinia and a new species (Hydractinia calderi n. sp.) is described. The medusae of the medusa-based genera Hansiella

An analysis of the community composition of the Xiphophora gladiata dominated subzone of the Tasmanian sublittoral fringe [PDF]
The rocky shore sublittoral fringe of the oceanic coasts of Tasmania contains a subzone dominated by the large brown alga Xiphophora gladiata. The community composition of this subzone is here examined at fourteen sites. The phytal and faunal assemblages

ABSTRACT Chironomidae, so‐called non‐biting midges, are considered key bioindicators of aquatic ecosystem variability. Data derived from morphologically identifying their chitinous remains in sediments document chironomid larvae assemblages, which are studied to reconstruct ecosystem changes over time.

Approximately 150 years of research on freshwater jellyfish globally have resulted in a considerable amount of information. However, this is not comprehensively available to most researchers worldwide. Scattered information allows only for a fragmented view of the research field, which mediated by climate change received increasing importance.

Intrapopulation Sex Ratio Variation in the Salt Grass Distichlis spicata [PDF]
In many dioecious plant populations, males and females appear to be spatially segregated, a pattern that is difficult to explain given its potentially high costs.

Update of the risk assessment of brominated phenols and their derivatives in food
Abstract The European Commission asked EFSA to update its 2012 risk assessment on brominated phenols and their derivatives in food, focusing on five bromophenols and one derivative: 2,4,6‐tribromophenol (2,4,6‐TBP), 2,4‐dibromophenol (2,4‐DBP), 4‐bromophenol (4‐BP), 2,6‐dibromophenol (2,6‐DBP), tetrabrominated bisphenol S (TBBPS), tetrabromobisphenol S
