Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Filter feeders living on suspension feeders: New insights into the lifestyle and distribution of Arcturidae Dana, 1849 (Crustacea: Isopoda) around Iceland

Marine Ecology, EarlyView.
Abstract The focus of the present study was on arcturid isopods occurring in the subarctic region around Iceland. Data from two decades of sampling with an epibenthic sledge (EBS) during numerous expeditions of the BIOICE (Benthic Invertebrates of Icelandic Waters; 1992–2004) and IceAGE (Icelandic marine Animals: Genetics and Ecology; 2011—ongoing ...

Incipient sexual isolation in Laupala cerasina: Females discriminate population-level divergence in acoustic characters

Current Zoology, 2012
Sexual selection by female choice can shape the evolution of male traits within populations, since the most attractive males experience an increase in fitness through elevated mating success. Speciation by sexual selection occurs when evolution in traits

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, EarlyView.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Ecological change may be a common initiator of evolutionary pollinator shifts

New Phytologist, EarlyView.
Summary Although evolutionary pollinator shifts are accepted as major sources of floral and species diversity in angiosperms, the mechanisms triggering pollinator shifts remain largely unexplored. In 1970, Stebbins proposed that ecological change may be a common initiator of evolutionary pollinator shifts, but empirical tests of Stebbins' hypothesis ...

Photosynthetic primary production in the Mesoproterozoic

New Phytologist, EarlyView.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Chromosome‐Level Genome Assembly of the Allotetraploid Gynostemma pentaphyllum Provides Novel Insights Into the Biosynthesis of Ginsenoside and Gypenoside LVI

Plant Biotechnology Journal, EarlyView.
ABSTRACT Gynostemma pentaphyllum, a herb used in tea and traditional Chinese medicine, shows geographic variation in its production of valuable dammarane‐type ginsenosides and gypenoside LVI between populations from Suining (SN) and Nanning (NN). To elucidate the mechanisms underlying this differential metabolite accumulation, a chromosome‐level genome

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.
