Homogeneity assessment of phenological records from the Swiss Phenology Network

International Journal of Biometeorology, 2019
Phenological data have become increasingly important as indicators of long-term climate change. Consequently, long-term homogeneity of the records is an important aspect. In this paper, we apply a breakpoint detection algorithm to the phenological series from the Swiss Phenology Network (SPN).

Rotala myanmarensis sp. nov. (Lythraceae) from Myanmar and taxonomic reassessment of Rotala occultiflora var. leichhardtii

Nordic Journal of Botany, EarlyView.
A new species of Rotala, viz. R. myanmarensis is described from Myanmar. It is characterized by 4‐merous flowers, lanceolate petals, linear‐ligulate nectary glands, and ovate seeds. Additionally, R. occultiflora var. leichhardtii is elevated to the rank of species as R. leichhardtii, based on morphological evidence, and is lectotypified.

Biotic and thermal drivers alter zooplankton phenology in western Lake Erie

Limnology and Oceanography Letters
Environmental change, particularly warming and eutrophication, can alter phenology in aquatic systems. Understanding controls on zooplankton phenology is important due to their central role in food webs.
