Comparing sample bias correction methods for species distribution modeling using virtual species

open access: yesEcosphere, Volume 12, Issue 3, March 2021., 2021
Abstract A key assumption in species distribution modeling (SDM) with presence‐background (PB) methods is that sampling of occurrence localities is unbiased and that any sampling bias is proportional to the background distribution of environmental covariates.

Estimating rates and patterns of diversification with incomplete sampling: a case study in the rosids

open access: yesAmerican Journal of Botany, Volume 107, Issue 6, Page 895-909, June 2020., 2020
Premise Recent advances in generating large‐scale phylogenies enable broad‐scale estimation of species diversification. These now common approaches typically are characterized by (1) incomplete species coverage without explicit sampling methodologies and/or (2) sparse backbone representation, and usually rely on presumed phylogenetic placements to ...

Elaiophores: their taxonomic distribution, morphology and functions

open access: yesActa Botânica Brasílica
Elaiophores are floral glands that secrete non-volatile oils as a reward for their pollinators. Their secretions mediate a specialized interaction between oil-producing plants and a few species of oil-collecting bees - Apidae and Melittidae.
