An eDNA Survey of Plant Biodiversity in a Local Dam Within South Africa's Largest City. [PDF]

Ecol Evol
Ecological information is needed to establish, implement and monitor such biodiversity management plans. This study employs environmental DNA to provide a good overview of plant community structure in an urban dam in Johannesburg, South Africa. It further reveals a gap in the taxonomic coverage of South African plants on public DNA databases.

Ecological Isolation Maintains the Species Boundaries Between Two Sympatric <i>Cycas</i> From Southwest China. [PDF]

Ecol Evol
The study reveals that sympatric Cycas species (C. pectinata and C. simplicipinna) maintain strict species boundaries without hybridization, driven by reproductive isolation mechanisms (divergent coning times and pollinator specificity) and ecological niche differentiation (habitat preferences, soil pH differences).

Cryptic signals: substomatal architecture influences stomatal responses to red light and CO2 [PDF]

new phytologist
Summary The mesophyll provides a critical signal for stomatal responses to red light (RL) and CO2 in angiosperms. By contrast, the stomatal response to blue light (BL) is largely guard cell‐specific. It is not known whether substomatal or mesophyll anatomy influences the effectiveness of the mesophyll signal driving stomatal responses to RL and CO2 ...

Eobowenia gen. nov. from the early Cretaceous of Patagonia: indication for an early divergence of Bowenia? [PDF]

, 2017
Background: Even if they are considered the quintessential "living fossils", the fossil record of the extant genera of the Cycadales is quite poor, and only extends as far back as the Cenozoic.

Zamia inermis, the more threatened cycad of Mexico [PDF]

, 2017
Zamia inermis (Zamiaceae) es una cícada rara, endémica y actualmente listada en Peligro Crítico de Extinción. De la misma, sólo se conoce una población compuesta de tres subpoblaciones, que se encuentra distribuido en tan sólo 2,5 km2 de pastizales y ...

Pollen morphology of the Megamexican cycads reveals the potential of morphometrics to identify cycad genera

Botan‪ical Sciences, 2020
Background: Although pollen morphology has always been an important tool in plant systematics, the possibility of distinguishing between related taxa is still debated. A difficult case is the cycads, where their morphology and small size is very similar.

Fighting their last stand? A global analysis of the distribution and conservation status of gymnosperms [PDF]

, 2015
Aim: Gymnosperms are often described as a marginal and threatened group, members of which tend to be out-competed by angiosperms and which therefore preferentially persist at higher latitudes and elevations.
