The functional implications of tracheary connections across growth rings in four northern hardwood trees. [PDF]
Ann Bot, 2019 BACKGROUND AND AIMS Deciduous angiosperm trees transport xylem sap through trunks and branches in vessels within annual growth rings. Utilizing previous growth rings for sap transport could increase vessel network size and redundancy but may expose new ...

Growth rings of Brazil nut trees (Bertholletia excelsa) as a living record of historical human disturbance in Central Amazonia. [PDF]
PLoS One, 2019 The Brazil nut tree (Bertholletia excelsa) is an iconic and economically valuable species that dominates vast swathes of the Amazon Basin. This species seems to have been an important part of human subsistence strategies in the region from at least the ...

First record of growth rings for 11 native subtropical anuran species of South America [PDF]
Anais da Academia Brasileira de Ciências, 2019 : Skeletochronology is the most accurate method to estimate a population age structure. The methodology is based on the analysis of secondary bone tissue in order to count growth rings.

Fingerprinting snakes: paleontological and paleoecological implications of zygantral growth rings in Serpentes [PDF]
PeerJ, 2018 We introduce a new non-destructive source of skeletochronological data with applications to species identification, associating disarticulated remains, assessing minimum number of individuals (MNI), and collection management of fossil snakes, but with ...

Occurrence of annual growth rings in Rhizophora mangle in a region with low climate seasonality
Anais da Academia Brasileira de Ciências, 2016 The formation of annual growth rings has been confirmed for several mangrove species in the last decade, among which is the Rhizophora mangle. However, the record of annual rings for this species was made in a region with high hydric seasonality, a ...

Experimental Induction of Extreme Indented Growth Rings (Hazel Wood) in Pinus halepensis Miller by Wide and Long Parallel Bark and Vascular Cambium Woundings [PDF]
PlantsIndented growth rings were found long ago to be experimentally induced in Pinus halepensis Miller by thin parallel axial scratching of the bark up to the vascular cambium with a sharp blade.

Oligarchic Growth of Protoplanets in Planetesimal Rings
The Astrophysical JournalIn the standard planet formation scenario, planetesimals are assumed to form throughout the protoplanetary disk and to be smoothly distributed in the radial direction except for the snowline.

Isotopic comparison and correlation of δ13C between bulk wood and cellulose of Vitis vinifera L.
OENO One, 2023 This study aims to compare the δ13C isotopic signal between bulk wood and α-cellulose in wood samples from the main trunk of Vitis vinifera L. to verify whether α-cellulose extraction is necessary for ecophysiological studies in this species.
