Integrating petrology, biogeochemistry, hyperspectral and thermal remote sensing for constraining the shallow hydrology of geothermal systems: Waiotapu Geothermal Field, Taupo Volcanic Zone, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 3, Page 493-506, September 2025.
ABSTRACT Studying geothermal areas can require significant resources, especially in areas densely covered by vegetation. This study integrates remote sensing techniques, including hyperspectral, thermal infrared and LiDAR with petrology and biogeochemistry of rock, soil and plant samples to develop a new shallow hydrogeological conceptual model of ...

Cryo‐SEM and large volume FIB‐SEM of Arabidopsis cotyledons: Degradation of lipid bodies, biogenesis of glyoxysomes and reorganisation of organelles during germination

Journal of Microscopy, Volume 299, Issue 3, Page 242-267, September 2025.
Abstract Until recently, the lack of three‐dimensional visualisation of whole cells at the electron microscopic (EM) level has led to a significant gap in our understanding of the interaction of cellular organelles and their interconnection. This is particularly true with regard to the role of the endoplasmic reticulum (ER).

Response of cytokinins and nitrogen metabolism in the fronds of Pteris sp. under arsenic stress.

PLoS ONE, 2020
Given the close relationship between cytokinins (CKs), photosynthesis and nitrogen metabolism, this study assessed the effect of arsenic (As) contamination on these metabolic components in the As-hyperaccumulators Pteris cretica L. var.

Was the Dry Diagonal of South America a Barrier for Dispersing Pteridaceae (Polypodiopsida) Species Between the Brazilian Atlantic Forest and Amazon Forest?

Journal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim We sought to assess how phylogenetic patterns within the fern family Pteridaceae are related to the history of the Amazon Forest and the Brazilian Atlantic Forest, as well as the Dry Diagonal of South America. The age of taxa present in these regions was estimated, as well as those found in previously identified areas of endemism for the ...
