Wave exposure shapes reef community composition and recovery trajectories at a remote coral atollNARA Subscribed
In a time of unprecedented ecological change, understanding natural biophysical relationships between reef resilience and physical drivers is of increasing importance. This study evaluates how wave forcing structures coral reef benthic community composition and recovery trajectories after the major 2015/2016 bleaching event in the remote Chagos Archipelago, Indian Ocean. Benthic cover and substrate rugosity were quantified fro...
A shift from phenol to silica‐based leaf defences during long‐term soil and ecosystem developmentNARA Subscribed
The resource availability hypothesis predicts that plants adapted to infertile soils have high levels of anti‐herbivore leaf defences. This hypothesis has been mostly explored for secondary metabolites such as phenolics, whereas it remains underexplored for silica‐based defences. We determined leaf concentrations of total phenols and silicon (Si) in plants growing along the 2‐million‐year Jurien Bay chronosequence, exhibiting...
Newly discovered cichlid fish biodiversity threatened by hybridization with non‐native speciesNARA Subscribed
Invasive freshwater fishes are known to readily hybridize with indigenous congeneric species, driving loss of unique and irreplaceable genetic resources. Here we reveal that newly discovered (2013–2016) evolutionarily significant populations of Korogwe tilapia ( Oreochromis korogwe ) from southern Tanzania are threatened by hybridization with the larger invasive Nile tilapia ( Oreochromis niloticus ). We use a combination of m...
Soil nutrients influence the distribution of tree species in lowland tropical forests, but their effect on productivity, especially at local scales, remains unclear. We used tree census, canopy occupancy, and soil data from the Barro Colorado Island (BCI; Panama) 50‐ha forest dynamics plot to investigate the influence of soil nutrients and potential toxins on aboveground tree productivity. Growth was calculated as the increase...
Climate and soils together regulate photosynthetic carbon isotope discrimination within C 3 plants worldwideNARA Subscribed
Aim Within C 3 plants, photosynthesis is a balance between CO 2 supply from the atmosphere via stomata and demand by enzymes within chloroplasts. This process is dynamic and a complex but crucial aspect of photosynthesis. We sought to understand the spatial pattern in CO 2 supply–demand balance on a global scale, via analysis of stable isotopes of carbon within leaves (Δ 13 C), which provide an integrative record of CO 2 drawd...
