Are We Witnessing a Speciation Continuum? Evidence From Current and Past Gene Flow in the Genus Oritrophium s.s. (Asteraceae) From the Tropical High Andes

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Determining species boundaries is key for appropriately assessing biodiversity. However, the continuity of the speciation process makes delimiting species a difficult task, especially for recently diverged taxa. Furthermore, past introgression may leave traces that result in reticulate evolutionary patterns, challenging the estimation of ...

Assessment Method for Leaf Litters Allelopathic Effect on Cyanobacteria [PDF]

open access: yes, 2005
A new bioassay technique combining leaf disk and softagar over-layer methods was developed to investigate the allelopathic effect of deciduous leaf litters on the growth of cyanobacteria ( Microcystis aeruginosa Kütz.).

Structural determinants for red‐shifted absorption in higher‐plants Photosystem I

open access: yesNew Phytologist, EarlyView.
Summary Higher plants Photosystem I absorbs far‐red light, enriched under vegetation canopies, through long‐wavelength Chls to enhance photon capture. Far‐red absorption originates from Chl pairs within the Lhca3 and Lhca4 subunits of the LHCI antenna, known as the ‘red cluster’, including Chls a603 and a609.

Bioelectrochemical detection of cyanobacteria for harmful bloom management [PDF]

open access: yes, 2019
High levels of nutrients and increasing temperatures favour the periodic proliferation of harmful cyanobacterial blooms with catastrophic effects for aquatic ecosystems. The production of toxins that occurs naturally as secondary metabolites is a major concern for public health.

Could photoperiodic responses have evolved before the emergence of circadian clocks?

open access: yesNew Phytologist, EarlyView.
Summary Plants use photoperiod (i.e. day length) as a seasonal cue for timing when to flower. This ability, known as photoperiodism, also underlies phenomena such as migration, seasonal reproduction, and hibernation in animals. Because a circadian (daily) clock underlies the day/night length timing mechanism in most organisms, it has been generally ...

Metagenomics reveals spatial variation in cyanobacterial composition, function, and biosynthetic potential in the Winam Gulf, Lake Victoria, Kenya

open access: yesApplied and Environmental Microbiology
The Winam Gulf in the Kenyan region of Lake Victoria experiences prolific, year-round cyanobacterial harmful algal blooms (cyanoHABs) which pose threats to human, livestock, and ecosystem health.

“Is This Edible Anyway?” The Impact of Culture on the Evolution (and Devolution) of Mushroom Knowledge

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Mushrooms are a ubiquitous and essential component in our biological environment and have been of interest to humans around the globe for millennia. Knowledge about mushrooms represents a prime example of cumulative culture, one of the key processes in human evolution.
