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.

Two new species of Calea ser. Multiplinerviae (Asteraceae: Neurolaeneae) from Brazil

Nordic Journal of Botany, EarlyView.
Detailed studies of specimens from Rondônia and Mato Grosso do Sul showed that two new species have been misidentified: Calea micropappa resembles Calea pilosa, but differs by leaf apex obtuse to acuminate (versus acute), paleae present (versus paleae absent), disc corolla lobes 1.2–1.3 mm long (versus 0.7–0.8 mm), and pappus scales 0.1–0.25 mm long ...

The Trèmols Herbarium: A European Herbarium from the End of the 19th Century

Diversity
The herbarium Trèmols, preserved in the Botanical Institute of Barcelona (IBB), was created during the second half of the 19th century by the Catalan chemist and botanist Frederic Trèmols Borrell (Cadaqués 1831–1900). He was a member of important scientific institutions, including the Real Acadèmia de Ciències i Arts de Barcelona, the Societat Botànica

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.

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

Nordic Journal of Botany, EarlyView.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

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.

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

Oikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

Botanical diversity as a reservoir of resilience: The emergence of new uses of wild plants under acute food shortages in Karamoja, Uganda

People and Nature, EarlyView.
Abstract Agro‐pastoralist communities in Karamoja, Uganda, face food insecurity driven by climate variability, declining livestock numbers and crop failures. In this context, local ethnobotanical knowledge systems play a central role in subsistence and adaptation.
