Rediscovery of Strobilanthes panichanga and discovery of Strobilanthes parryorum (Acanthaceae): two endangered species from the hills of Dima Hasao, Assam, India

open access: yesNordic Journal of Botany, EarlyView.
We report on two species of Strobilanthes Blume. Strobilanthes panichanga (Nees) T.Anderson has been rediscovered in the Dima Hasao district of Assam, India, after a very long gap of 150 years, and Strobilanthes parryorum C.E.C.Fisch has been discovered for the first time in Assam, India.

VARIABILIDAD EN RASGOS POLINICOS EN EL COMPLEJO MIMULUS LUTEUS L. (PHRYMACEAE) EN CHILE CENTRAL VARIABILITY OF POLLEN TRAITS IN THE MIMULUS LUTEUS L. (PHRYMACEAE) COMPLEX IN CENTRAL CHILE

open access: yesGayana: Botanica, 2004
We quantified the variability of pollen morphology and life history traits among three natural populations of two taxa in the Mimulus luteus complex and a group of putative hybrids that coexist in the Andean ranges of central Chile.

Hechtia mixtecana sp. nov. (Hechtioideae; Bromeliaceae), from Oaxaca, Mexico

open access: yesNordic Journal of Botany, EarlyView.
Botanical explorations carried out in the state of Oaxaca, Mexico, led to the discovery of a new Bromeliaceae: Hechtia mixtecana,which is here described and illustrated. The new taxon is compared with the morphologically similar Hechtia fragilis, Hechtia lyman‐smithii, and Hechtia minuta.

Reconstructing Early Human Subsistence in Near Oceania: New Insights From Matenkupkum and Matenbek

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The colonization of New Ireland ~44–40,000 years ago represents the earliest evidence of human occupation in Near Oceania. Yet, the precise impacts of climatic changes on subsistence strategies during the Late Pleistocene, Last Glacial Maximum, and Holocene remain poorly understood.

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

open access: yesOikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

open access: yesOikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

The fate of pollen in two morphologically contrasting buzz-pollinated Solanum flowers

open access: yesJournal of Pollination Ecology
Pollen transfer efficiency (PTE) and pollen deposition patterns on a pollinator’s body significantly influence plant reproductive success. However, studies on pollen fates (i.e., the destination of pollen grains after anther dehiscence) in animal ...

The Age and Origin of Block Deposits in the Victorian Alps, Australia

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in
