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.

Cuon Versus Canis: A Comparative Guide to the Morphological Distinction of Postcranial Bones and Its Archaeo‐Paleontological Implications

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The genera Cuon and Canis are part of the carnivore guild during the late Middle and Late Pleistocene in Europe. However, most identifications in archaeo‐palaeontological contexts are made on cranial and dental elements as these are taxonomically the most diagnostic anatomical regions.

The impact of gigafire on vegetation structure, terrestrial vertebrate abundance and diel activity

open access: yesOikos, EarlyView.
Fire regimes are shifting around the world due to climate and land‐use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood. Particularly lacking is an understanding of how fire affects animal behaviour.

Quantifying community keystoneness in metacommunities under disturbance

open access: yesOikos, EarlyView.
Understanding how metacommunities respond to natural and anthropogenic disturbances is a key objective in ecology. In this study, we introduce an analytical framework to identify communities whose extirpation triggers stronger (hereafter keystone communities) or weaker (hereafter idle communities) cascading effects on extinction and colonization events

Limited impacts of simulated soil disturbance by rewilded vertebrates on above‐ and below‐ground biodiversity

open access: yesOikos, EarlyView.
Rewilding with locally extinct terrestrial vertebrates has been a popular conservation initiative over the past few decades. Among the animals used for rewilding are the small‐ to medium‐sized vertebrates that forage in the soil and that have been lost from many ecosystems due to habitat destruction or predation by exotic species.
