Over centuries of plant morphological research, biologists have enthusiastically explored
how distinct vascular arrangements have diversified. These investigations have focused on …

Secondary growth from a vascular cambium, present today only in seed plants and
isoetalean lycophytes, has a 400‐million‐yr evolutionary history that involves considerably …

Evidence for secondary growth extends into the Early Devonian, 407 million years ago,
raising questions about tempo and mode of origination of this key developmental feature. To …

Los censos de fauna son fundamentales para conservar la biodiversidad de una región o
área determinada. Además, frente a problemáticas de conservación de los ecosistemas …

The occurrence of conducting vascular tissue in the pith (CVTP) of tracheophytes is
noteworthy. Medullary bundles, one of the remarkable examples of CVTP, evolved multiple …

Studies of anatomically preserved fossils provide a wealth of information on the evolution of
plant vascular systems through time, from the oldest evidence of vascular plants more than …

We studied degradation patterns and microorganisms preserved in permineralized stems of
Rhexoxylon piatnitzky, Protojuniperoxylon ischigualastense, and Agathoxylon argentinum …

Earth's land plants have been shaped by tectonic, climatic and atmospheric evolution for at
least 400 million years. The rift basins of Argentina record a continuous record of Triassic …

Secondary growth from a vascular cambium (woody growth), like other complex
developmental processes, is regulated in a modular fashion (Tomescu and Groover, 2019; …

El propósito de este trabajo es analizar la anatomía y determinar sistemáticamente las
maderas pro cedentes de las sedimentitas del Triásico Superior de la Formación Llantenes …
