Phylogeny of Saxifragales (Angiosperms, Eudicots): Analysis of a Rapid, Ancient Radiation [PDF]
Rapid, ancient radiations pose one of the most difficult challenges for phylogenetic estimation. We used DNA sequence data of 9,006 aligned base pairs from five genes (chloroplast atpB, matK, rbcL, and 18S and 26S nrDNA) to elucidate relationships among major lineages of Saxifragales (angiosperms, eudicots). These relationships were poorly supported in

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Stéréostructure de l'exine des Saxifragales: proposition d'une description logique et schématique [PDF]
ResumeUne methodologie descriptive schematique est proposee pour la traduction des informations nombreuses apportees par les micrographies M.E.B. Elle devrait eviter une terminologie contestable, trop souvent illogique (description desordonnee), surchargee de paraphrases et limitee par les barrieres linguistiques.

A new species of aphid of the genus Nipponaphis (Hemiptera: Aphididae: Hormaphidinae) from China, inducing galls on the trunk of a witch-hazel (Hamamelidaceae) [PDF]
Plants and insects have co-existed for millions of years. Although research has been conducted on various insect species that induce galls on various plant tissues, information is particularly scarce when it comes to insects that form galls on the tough ...

Unraveling Biogeographic Boundaries Within the Sierra Madre Oriental, México: An Endemicity Analysis Using a Taxonomically Diverse Dataset. [PDF]
We provide boundaries of the Sierra Madre Oriental in Mexico through a multi‐taxa endemicity analysis. ABSTRACT The Sierra Madre Oriental (SMO) is a significant mountain range and one of Mexico's 14 biogeographical provinces. Its delimitation has been debated.

Pollinators can play an important role in production improvement in organic farming. It is, therefore, essential to ensure their year-round availability, particularly in winter season in Sikkim Himalaya. Thus, attempts were made to explore resources which could support and provide switching over platforms to pollinators during the winter season ...

Dual Isotope Analysis Reveals Phylogenetic Patterns and Novel Insights Into Methoxy Group Synthesis of Structural Biomolecules in Leaf and Woody Plant Tissues. [PDF]
ABSTRACT Stable carbon and hydrogen isotopes of wood methoxy groups (δ2Hmeth, δ13Cmeth), mainly sourced by structural biomolecules like lignin and pectin, provide important insights into climatic, hydrological and physiological conditions. This study systematically investigated species‐specific δ2Hmeth and δ13Cmeth variations in leaves and woody twigs ...
