Optimal Dimensionality Selection Using Hull Heatmaps for Single‐Cell Analysis

open access: yesComputer Graphics Forum, EarlyView.
We propose two types of hull heatmaps to assist in selecting the optimal dimensionality in single‐cell analysis: the cell type heatmap, displaying overlaps between cell types, and the cluster heatmap, comparing cell clustering results. In quantitative evaluations, ours yielded downstream analysis results that were comparable to or better than others ...

Finding floral and faunal species richness optima among active fire regimes

open access: yesConservation Biology, EarlyView.
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

The what, how, and why of trait‐based analyses in ecology

open access: yesEcography, EarlyView.
Functional diversity is increasingly used alongside taxonomic diversity to describe populations and communities in ecology. Indeed, functional diversity metrics allow researchers to summarise complex occupancy patterns in space and/or time across communities and/or populations in response to various stressors.

Assessing the effects of mowing intensity on the overwintering stem‐dwelling insect community of Solidago altissima L. (Asterales: Asteraceae)

open access: yesInsect Conservation and Diversity, EarlyView.
Overwintering stem‐dwelling insects exhibit a non‐random spatial structure within individual stems and within different subsections of an urban meadowscape. Low intensity mows lead to higher survival rates of overwintering stem‐dwelling insects than no mowing and high intensity mows.

Species traits modulate ecological release in island red devil spiders (Araneae: Dysderidae)

open access: yesInsect Conservation and Diversity, EarlyView.
We studied the species ability to undergo an ecological release process in the red devil spiders (Araneae: Dysderidae) when colonising species‐depauperate environments, focusing on different aspects of their niche. We have found that the ability to expand their niche is highly dependent on the species trophic strategy, with specialist species being ...
