Developing a habitat suitability index with field data and hydraulic models

open access: yesRiver Research and Applications, Volume 40, Issue 10, Page 1903-1911, December 2024.
Abstract Linking habitat availability with hydraulic models integrates river engineering in the ecological field. Field observation for species presence and physical habitat availability mapping is inherently limited due to time and access constraints for field data collection.

Combining spaceborne lidar from the Global Ecosystem Dynamics Investigation with local knowledge for monitoring fragmented tropical landscapes: A case study in the forest–agriculture interface of Ucayali, Peru

open access: yesEcology and Evolution, Volume 14, Issue 8, August 2024.
We employed a co‐production approach leveraging spaceborne lidar and local knowledge to investigate the structural characteristics of the forest‐agriculture interface in Ucayali, Peru. Results indicated higher relative height ratios (RH50/RH95 and RH75/RH95) for mature forest compared to secondary forest (p < .0001), even after accounting for the ...

Net primary productivity and litter decomposition rates in two distinct Amazonian peatlands

open access: yesGlobal Change Biology, Volume 30, Issue 8, August 2024.
Our understanding of carbon cycling in tropical peatlands is limited by the lack of data on forest productivity and litter decomposition. Here we present measurements from two floristically distinct Amazonian peatland forests, a palm‐dominated swamp and a thin‐stemmed hardwood swamp.
