A practical prioritization strategy for vegetation-focused restoration of anthropogenic wastelands

By Erika Stewart, Joshua Grinath & Kathryn Turner

doi.org/10.1002/ajb2...

#botany #plantscience #ecology

An anthropogenic wasteland restoration framework depicted as a heatmap for assessing priorities and management strategies for wastelands in local proximity to high-quality habitats from low to high (x-axis), and landscapes that are unfragmented (low fragmentation) to highly fragmented (y-axis).

From ice age to present: Clonal expansion & genetic variation in the world's oldest #conifer stand

New #AJB research by James Marthick, Andrew Phipps, Gregory Jordan, Daiki Takahashi, Yoshihisa Suyama & James Worth

doi.org/10.1002/ajb2...

#botany #plantscience #genetics

In vitro propagation of woody semi-mangrove species is often constrained by explant contamination, browning and stage-specific morphogenic responses. The authors examined how explant developmental state, basal-medium strength and plant growth regulators affected in vitro establishment and regeneration responses in Heritiera littoralis.

"Ferns, marsupials, and Darwin's Wedge: Does competitive displacement really explain macroevolutionary patterns in #ferns?"

#botany #plantscience

Unfurling fronds of Struthiopteris spicant in Northern California. Many lineages of ferns went extinct in the Paleozoic, but as a whole ferns have persisted for nearly 400 million years, and extant ferns have expanded into nearly all terrestrial ecosystems. Does competitive displacement really explain their Paleozoic evolutionary patterns? (Credit: Jacob Suissa.)

Describing the cones & seeds of extinct #conifer species---using CT and 3D visualization---that co-existed with the dinosaurs 150 million years ago in what is today the state of Utah.

#botany #paleobotany #fossils

Using an industrial-strength CT scanner, the authors of this study were able to look inside a new species of a 151-million-year-old conifer cone from Utah to see the three spirals of seeds preserved inside, without having to cut open the precious fossil.

Bird #pollination in three species of #Phlogacanthus & its broader implications for bird–flower interactions in Asia

#botany #plantscience #Acanthaceae #sunbirds #spiderhunters

In the morning sunshine, using its long bills, a streaked spiderhunter is starting to enjoy the nectar concealed in the long pink corolla tubes of Phlogacanthus curviflorus, which depends exclusively on spiderhunters for pollination. This scene takes place in the monsoon forest in southwestern China.

Exposure to heat waves & #drought improves subsequent leaf heat tolerance for five #oak species in southern California

By Casey Wisely et al.
doi.org/10.1002/ajb2...

#climatechange #botany #Quercus

A figure summariing leaf heat tolerance, represented by T 50 (the temperature at which the maximum quantum efficiency of photosystem II is reduced by 50%), for five species of oak tree native to Los Angeles County, California, USA that received either regular watering (plain bars) or reduced watering (diagonal bars). Measurements were made before (April) and after (September) multiple summer heat waves, which increased the leaf heat tolerance of all five species, particularly those with evergreen leaves.

#Abortifacients in Mesoamerica & the Southwest United States: Botanical & sociocultural perspectives

By Guadalupe Maldonado Andrade

#botany #ethnobotany #plantsciences

A moment captured by Mahé Elipe (@mahelipe) of an ethnographic storytelling session with abortion companions through shared stories, objects, plants, and experiences. This session created space to reflect on abortion care, accompaniment, embodied knowledge, and the ways reproductive knowledge is held and passed between communities.

At the edge of change: Native #Phragmites persistence & nonnative arrival along the dam-regulated #ColoradoRiver

New #AJB research by Emily Palmquist, Joel Sankey, Claudia DiMartini, Tayan Benson, Brooke Damon et al.

#botany #plantscience #conservation #Poaceae

Native common reed - Phragmites australis subsp. americanus Saltonst., P.M. Peterson & Soreng, Colorado River, Grand Canyon National Park, Mohave County, Arizona, September 7, 2021. Present in the Grand Canyon for more than 40,000 years, native Phragmites has established itself as a key ecological component of desert wetlands and an important cultural species for many southwestern Native American Tribes. At present, the Grand Canyon region and a hydropower dam are supporting large, diverse native Phragmites populations, but these are threatened by the recent arrival of the invasive subspecies, Phragmites australis subsp. australis (Cav.) Trin. ex Steud. (Image credit: E. Palmquist.)
