Ecology and Evolution of Gall-Inducing Arthropods: The Pattern From the Terrestrial Fossil Record
Insect and mite galls on land plants have a spotty but periodically rich and abundant fossil record of damage types (DTs), ichnotaxa, and informally described gall morphotypes.

Phylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...

Surveillance of Levofloxacin Resistance in Helicobacter pylori Isolates in Bogotá-Colombia (2009-2014). [PDF]
Increased resistance of Helicobacter pylori to clarithromycin and metronidazole has resulted in recommendation to substitute fluoroquinolones for eradication therapy.

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 ...

Wildfire and intensive site preparation influence beetle assemblages by shaping habitat heterogeneity, with wildfire fostering biodiversity while disc trenching leads to long‐term species declines due to habitat homogenization. Post‐fire beetle succession follows a predictable trajectory, with early successional species dominating open habitats and ...

Behaviour of European Spruce Bark Beetle—Ips typographus (L.) on Poisoned Traps
ABSTRACT Deployment of poisoned trap trees/logs is an efficient suppressive method to fight Ips typographus (L., 1758) (Coleoptera: Curculionidae: Scolytinae), a calamity pest of spruce stands in the European area during the gradation period. Logs from Picea abies (L.) H.

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration
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‐

Abstract Eriocaulaceae is a pantropical family of approximately 1200 species across 18 genera, with its highest diversity in the Neotropical region. Traditionally, the family has been divided into two subfamilies, Eriocauloideae and Paepalanthoideae, based on floral traits. Here, we use target‐capture sequencing of nuclear markers to test the monophyly

NGATHA carpel development genes evolved in the common ancestor of seed plants
SUMMARY The evolution of the carpel, the defining feature of angiosperms, remains a fundamental question in plant biology. Understanding how this organ originated is crucial because it underpins the reproductive success and diversity of flowering plants.
