Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

Nordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Leaf Economics and Local Adaptation: Genetic and Plastic Responses Within Mediterranean Annual Species to Macro‐ and Microclimatic Aridity Gradients [PDF]

Ecol Evol
This study examined how Mediterranean annual plants adjust leaf traits (SLA and LDMC) across rainfall gradients and microclimates, considering both genetic differentiation and plasticity under drought and competition. Contrary to expectations from the Leaf Economics Spectrum, populations from drier macroclimates evolved more acquisitive leaves (higher ...

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]

, 2016
Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, EarlyView.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

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
