The phenological growth stages, heat unit requirement and anti‐tyrosinase activity of Greyia radlkoferi Szyszyl

open access: yesAnnals of Applied Biology, Volume 188, Issue 2, Page 549-560, March 2026.
Phenological growth stages of Greyia radlkoferi: The phenological growth stages of Greyia radlkoferi were monitored for a period of 3 years from 2018, 2019 and 2020. The flower budding, bud burst, flowering, fading, fruiting, seeding, leaf senescence and vegetative stage were recorded. The tyrosinase inhibitory activity of G.

Terrestrial climate variability and seasonality changes in the Mediterranean region between 15 000 and 4000 years BP deduced from marine pollen records [PDF]

open access: yes, 2009
Pollen-based climate reconstructions were performed on two high-resolution pollen marines cores from the Alboran and Aegean Seas in order to unravel the climatic variability in the coastal settings of the Mediterranean region between 15 000 and 4000 ...

Welcome Pathogens: Transient Heat Dampens Immune Responses to Acibenzolar‐S‐Methyl in Apple Plants

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1229-1248, March 2026.
ABSTRACT Climate change affects plant‐pathogen interactions, with disease outcome varying depending on the pathosystem and environmental scenario. In Arabidopsis, a thermo‐sensitive module of salicylic acid (SA) signalling makes immunity vulnerable to heat.

Pollination and Growth of Pollen Tubes in Common Juniper (Juniperus communis L.: Cupressaceae Rich. ex Bartl.) [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2019
Pollination and fertilization are crucial stages in sexual reproduction of coniferous plants. The period of high concentrations of airborne juniper pollen in the pollination season lasts no more than 4-6 hours within one calendar day.

Holocene fire regimes, fire‐related plant functional types, and climate in south‐coastal British Columbia forests

open access: yesEcosphere, 2023
Paleoecological records of past fire events and forest composition provide long‐term ecological context for modern changes in fire regimes and forest dynamics. Here, we use pollen and contiguous macroscopic charcoal analyses of lake sediments from Pender

LSTM‐Based Recurrent Neural Network Predicts Influenza‐Like‐Illness in Variable Climate Zones

open access: yesImmunity, Inflammation and Disease, Volume 14, Issue 2, February 2026.
ABSTRACT Background Influenza virus is responsible for a recurrent, yearly epidemic in most temperate regions of the world. Flu has been responsible for a high disease burden in recent years, despite the confounding presence of SARS‐CoV‐2. However, the mechanisms behind seasonal variance in flu burden are not well understood. This study seeks to expand

Extreme Potomac Floods at Washington D.C. During the Past 500 Years

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Washington D.C. faces one of the highest 100‐year flood risks of any major city along the U.S. East Coast. In addition to storm‐surge inundation during hurricanes and nor'easters, water‐level observations for Washington are strongly skewed by major floods on the Potomac River.

Intensification of the Southern Hemisphere westerly winds during the last deglaciation (18.5–14.0 cal ka BP): Evidence from Pearly Beach wetland on the southern Cape coast of South Africa

open access: yesJournal of Quaternary Science, Volume 41, Issue 1, Page 25-35, January 2026.
ABSTRACT The southwestern Cape of South Africa experiences a complex and dynamic climate, shaped by the interplay between the temperate Southern Hemisphere westerly winds and the subtropical easterlies. Despite the climatic sensitivity of the region, relatively few studies have examined how conditions have varied since the last deglaciation in response
