Canopy structure and understorey light availability in Nothofagus and podocarp‐broadleaf stands in a New Zealand forest

open access: yesNew Zealand Journal of Botany, Volume 62, Issue 4, Page 549-559, December 2024.
ABSTRACT The ability of some ectomycorrhizal fungi to access organic sources of nitrogen is known to influence decomposition, nitrogen mineralisation and soil carbon storage. The consequences for aboveground ecosystem structure and processes are less well‐documented. We used the LAI‐2200C Plant Canopy Analyzer to compare leaf area index and understorey

Diet of Andean Leaf‐Eared Mice (Phyllotis) Living at Extreme Elevations on Atacama Volcanoes: Insights From Metagenomics, DNA Metabarcoding, and Stable Isotopes

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
On the flanks of > 6000 m Andean volcanoes that tower over the Atacama Desert, leaf‐eared mice (Phyllotis vaccarum) live at extreme elevations that surpass known vegetation limits. We used a combination of metagenomics, DNA metabarcoding, and stable isotope analyses to investigate the diet of mice living in these extreme environments.
