Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

Nordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

PREDICTING POTENTIAL ASCOSPORE DOSE OF VENTURIA INAEQUALIS (CKE) WINT IN COMMERCIAL APPLE ORCHARDS OF NEW HAMPSHIRE (MODELING, EPIDEMIOLOGY, DISEASE MANAGEMENT) [PDF]

, 1984
A theoretical model (Prot. Ecol. 5:103-125) was the framework of a study of factors affecting the number of Venturia inaequalis ascospores per m(\u272) orchard floor per season (PAD) in New Hampshire apple orchards.

Ice storm effects on the canopy structure of a northern hardwood forest after 8 years [PDF]

, 2009
Ice storms can cause severe damage to forest canopies, resulting in differential mortality among tree species and size classes and leading to long-lasting changes in the vertical structure and composition of the forest.

Resource limitation and competition shape reproductive allocation and synchrony

Oikos, EarlyView.
The dynamics of reproductive allocation (RA) in herbaceous plant communities, particularly in response to varying environmental conditions such as drought stress and competitive interactions, remain underexplored. This study aims to fill this gap by hypothesising that both belowground resource limitation and the presence of dominant species ...

The role of forest genetic resources in responding to biotic and abiotic factors in the context of anthropogenic climate change [PDF]

, 2015
The current distribution of forest genetic resources on Earth is the result of a combination of natural processes and human actions. Over time, tree populations have become adapted to their habitats including the local ecological disturbances they face ...

Prospective of indigenous African wild food plants in alleviation of the severe iron deficiency anaemia in Sub‐Saharan Africa

PLANTS, PEOPLE, PLANET, EarlyView.
Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

The Romantic Discovery of Radiolaria in the Ocean. [PDF]

J Eukaryot Microbiol
ABSTRACT Radiolaria are unicellular marine organisms (protists) that have been drifting in oceanic plankton for hundreds of millions of years. These mineral architects can build extraordinarily complex skeletons, which fascinated and puzzled naturalists observing water samples through rudimentary microscopes.

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

Phytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Typifications in the tribe Browallieae (Cestroideae: Solanaceae)

TAXON, EarlyView.
Abstract The tribe Browallieae is a monophyletic group comprising Browallia and Streptosolen. These genera are of significant interest in the horticulture industry due to their ornamental potential. Despite their clear placement in Solanaceae, the tribe presents several taxonomic, phylogenetic, and nomenclatural challenges.
