Green's functions of the fractional Laplacian on a square: Boundary considerations and applications to the Lévy flight narrow capture problem
Published 2025-07-01“…This smooth problem can be solved for numerically using a basic finite difference scheme and leads directly to accurate extraction of the regular part of the Green's function (and its gradient, if so desired). Incorporating this new method for computing Green's functions into a matched asymptotic analysis framework enables us to provide new insights into the 2-D Lévy flight narrow capture problem beyond those of leading order theory. …”

Functional safeguards for conservation: Identifying climate change refugia for frugivorous and nectarivorous birds in a degraded area of Colombia.
Published 2025-01-01“…Two types of future climatic refugia (type 1: areas that will maintain the current climatic conditions and type 2: regions outside the current distribution area that will have the current climatic conditions) were identified to guide conservation efforts for these groups and associated ecosystem services. Of the 27 functional groups identified, 19 are projected to undergo range reductions of 1-75%, with an average upward shift of their climatic niches along the altitudinal gradient of 690 m. …”

Soil community history strengthens belowground multitrophic functioning across plant diversity levels in a grassland experiment
Published 2024-11-01“…Abstract Biodiversity experiments revealed that plant diversity loss can decrease ecosystem functions across trophic levels. To address why such biodiversity-function relationships strengthen over time, we established experimental mesocosms replicating a gradient in plant species richness across treatments of shared versus non-shared history of (1) the plant community and (2) the soil fauna community. …”

Climate and soil factors drive the functional and phylogenetic assembly of Qinghai-Tibetan grassland communities via multiple paths
Published 2025-03-01“…Despite their significance, the manner in which these structures change along environmental gradients has not been explored extensively. We estimated the phylogenetic diversity (PD) and community-weighted mean (CWM) and functional diversity (FD) values of four key functional traits in 558 grassland plots across the Qinghai-Tibetan Plateau (QTP) and assessed their relationship to climate and soil factors. …”
