Researchers shed light on moths & butterflies' evolution, conservation needs, and diverse feeding habits. Discoveries suggest that these insects obtained plant-digesting abilities from fungi, while mandibled moths were once more diverse but largely extinct.
A recent study from the University of Guam found that cycad cotyledons contribute to successful seedling growth through photosynthesis. The research reveals a robust cotyledon strategy for improving seedling persistence and biodiversity in competitive forest communities.
Researchers have discovered a novel type of wood that is highly efficient at carbon storage, thanks to its unique macrofibril structure. This discovery may lead to the development of new plantation forests capable of capturing large quantities of carbon dioxide.
A new fossil discovery in California has rewritten the scientific understanding of cycad plants, revealing a more dynamic evolutionary history than previously thought. The 80-million-year-old pollen cone found in Silverado Canyon is distinct from modern cycads, with differences in morphology and anatomy.
Researchers found that trees in tropical forests produce significantly more seeds than those in boreal regions, challenging the assumption that larger seeds mean fewer offspring. The studies also reveal that seed production is not constrained by seed size and provide new guidance for forest management and replanting.
A study on gymnosperm diversification reveals that gene duplications are linked to major pulses of phenotypic evolution. The researchers found that ecological opportunity and environmental heterogeneity drove a resurgence of gymnosperm diversification since the rise of angiosperms.
A new study reveals genome duplication events in ancient gymnosperms led to the origin of pines and other conifers, enabling them to adapt to changing ecosystems. The research suggests that duplicated DNA gave rise to unique traits such as diverse cone structures and egglike roots.
A new species of wasp-mimicking fly from South Korea has been discovered, with members twice the size of common house flies. The ancient insect, named after PSY's 'Gangnam Style', had distinct yellowjacket-like patterns on its abdomen.
Recent reports on gymnosperms' slow photosynthetic use of sunflecks prompted a call for cycad species study. Experimental protocols should be defined from natural habitats to accurately represent species behavior.
A newly discovered beetle, Darwinylus marcosi, provides direct evidence of a fourth major gymnosperm-insect pollination mode during the mid-Mesozoic era. The beetle's jaw-like mouthparts and chewing feeding style suggest that it was involved in pollination before flowering plants emerged.
A new study uses proteomics to analyze the composition of gymnosperm pollination drops, revealing species-specific germination media and anti-microbial proteins. This research provides a metabolic fingerprint, enabling further research into seed plant evolution and pollen-ovule interactions.
Genetic analysis suggests a single common ancestor triggered the emergence of flowers from pine cone-like structures, with water lilies as potential 'genetic fossils'. This discovery challenges expectations of distinct genetic instructions for each floral organ in early angiosperms.
The study compares genetic structures of Arabidopsis thaliana and Persea americana to understand how the first flowering plants evolved from non-flowering plants. Researchers found significant overlap among organ types, suggesting a genetic 'fossil' that allowed for flower transformation.
