Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

New Phytologist, EarlyView.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

PRODUCTIVE BEHAVIOUR OF TWELVE THREELINEAL FORAGE CORN HYBRIDS IN A DRY TROPICAL REGION

Tropical and Subtropical Agroecosystems, 2018
Twelve threelineal corn hybrids and one commercial variety were evaluated at Ahuacatlán, Nayarit; distance between furrows was 75 cm and a seed every 15 cm. Fertilizer was applied at one dosagee of 160-60-00.

Traits and functions of alpine plant communities respond strongly but not always sufficiently to in situ climate change

New Phytologist, EarlyView.
Summary Increasing climate warming and summer droughts are known to affect mountain plant communities, their functional traits and life strategies. However, little is known about how strongly and efficiently communities respond to climate change, and how tightly plant responses are linked to responses of ecosystem functions.

Harnessing the benefits of herbarium specimen digitisation for inferring recent and ongoing plant extinctions

New Phytologist, EarlyView.
Summary Evidence for the ongoing biodiversity crisis rests on assessment of a small fraction of described species, with major knowledge gaps for most organisms, including plants. Here, we highlight how digitised herbarium specimens can be used to accelerate and improve estimates of recent and ongoing plant extinctions.

Molecular–physiological model integration revolutionizes cereal flowering prediction

New Phytologist, EarlyView.
Summary Rapid prediction and control of flowering time is essential for breeding crops resilient to changing climates. Current models often fail to predict flowering time in new cultivars because molecular models lack integration of environmental signals, while physiological models inadequately capture the interactions of vernalization, photoperiod and

Starch synthesis in Brachypodium distachyon endosperm occurs in dynamic, connected amyloplast compartments

New Phytologist, EarlyView.
Summary The morphology of starch granules is a major determinant of the functional and nutritional properties of starch and is highly variable among cereal species. Much of this morphological variation stems from differences in the spatial and temporal patterns of starch granule initiation in amyloplasts during grain development.
