Phenological Predictability Index in BRAHMS: a tool for herbarium‐based phenological studies

open access: yesEcography, 2012
Phenological Predictability Index (PPI) is a tool for analysing phenological patterns incorporating herbarium data within BRAHMS (Botanical Research and Herbarium Management System). PPI produces a maximum‐activity period and associated event predictability index between ∼0 and 1.

Revisiting the taxonomy and nomenclature of Phyla, a small genus of Verbenaceae

open access: yesNordic Journal of Botany, EarlyView.
Phyla is unique within Verbenaceae due to the presence of malpighiaceous hairs. Its taxonomy has long been marked by difficulties in defining species boundaries. The most recent revision of the genus recognized five species and three varieties. In this study, however, we recognize only two species and no varieties: P.

Small collections, great findings: three new species and two new state records for Asteraceae from Brazil

open access: yesNordic Journal of Botany, EarlyView.
The BHZB herbarium was founded in 1993 with about 16 787 registers – a number that has to be considered as small when compared to larger herbaria in Brazil. In the BHZB, 97.5% of the vouchers are from the Minas Gerais state (ca 16 372 specimens), with Asteraceae being the best represented family.

Phenological response to climatic change depends on spring warming velocity

open access: yesCommunications Earth & Environment
Climatic change is dramatically altering phenology but generalities regarding tempo and mode of response remain limited. Here we present a general model framework incorporating spring temperature, velocity of spring warming, and species’ thermal ...

Roadkill risk in European birds: the role of detection and plumage colouration

open access: yesOikos, EarlyView.
Wildlife–vehicle collisions (WVCs) are a significant cause of mortality among European birds. This poses a threat to the conservation of birds because pervasive human‐related structures, such as road networks, are expected to expand over the continent in the next few decades.
