Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

Nordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

A new species and a synonym in Centaurea sect. Microlophus (Asteraceae, Cardueae–Centaureinae) from the Khuzestan Province, southwestern Iran

Nordic Journal of Botany, EarlyView.
A new species, Centaurea baghmalekensis Negaresh (Asteraceae) in C. sect. Microlophus (Cass.) DC., is described and illustrated from the Khuzestan Province, southwestern Iran. The new species is morphologically most similar to Centaurea pabotii Wagenitz, a recently described species from the Khuzestan Province.

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands

Nordic Journal of Botany, EarlyView.
Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network

Oikos, EarlyView.
In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.
