In flow tank experiments, I tested the relative importance of active and passive processes to larvae settling on manufactured casts that were hydrodynamically rough at a small scale (mm to <1 cm). I predefined two distinct regions of small-scale flow that I used to manipulate larval settlement behaviour of the red abalone Haliotis rufescens Swainson. The larvae show a stringent settlement respo...
Abstract. Arsad S, Putra KT, Latifah N, Kadim MK, Musa M. 2021. Epiphytic microalgae community as aquatic bioindicator in Brantas River, East Java, Indonesia. Biodiversitas 22: 2961-2971. One way to monitor water quality is by using biological indicators, namely epiphytic (periphyton). This study aims analyze the periphyton structure and river health status a saprobic index. The research locati...
The valorization of seaweeds has generated unprecedented interest in recent years due to their unique chemical characteristics. taxonomic differentiation between Chlorophyta, Rhodophyta, and Ochrophyta is often supported by contrasting Polar lipids are the most abundant class several species labelled as valuable phytochemicals. Nevertheless, little still known about how polar lipidome varies wi...
Phycobilins function as light-harvesting pigments in most cyanobacteria and red algae. Although green cyanobacteria of the genus Prochlorococcus express genes encoding enzymes that direct the synthesis of phycobilins, these pigments do not appear to play a role in light harvesting in Prochlorococcus. Now, it is shown that cyanophages infecting Prochlorococcus also contain genes for phycobilin-s...
Reef ecosystems built during successive periods of Pleistocene sea level rise have shown remarkable persistence in coral community structure, but little is known of the ecological characteristics of reef communities during periods of low sea stands or sea level falls. We sampled the relative species abundance of coral, benthic foraminifera, and calcareous red algae communities from eight submer...
Marine biologists and biogeographers have long been puzzled by apparently non-dispersive coastal taxa that nonetheless have extensive transoceanic distributions. We here carried out a broad-scale phylogeographic study to test whether two widespread Southern Hemisphere species of non-buoyant littoral macroalgae are capable of long-distance dispersal. Samples were collected from along the coasts ...
Algae are simple photosynthetic eukaryotes which—owing to their colonization of the oceans—are responsible for up to 50% of the planet’s atmospheric carbon fixation (22). They comprise a diverse group that can broadly be defined as unicellular (microalgae) or multicellular (macroalgae) photosynthetic organisms that lack roots, stems, leaves, conducting vessels, and complex sex organs (55). A si...
