Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Long‐term trends in global flowering phenology

New Phytologist
Summary Flowering phenology is an indicator of the impact of climate change on natural systems. Anthropogenic climate change has progressed over more than two centuries, but ecological studies are mostly short in comparison.

Flower power: tree flowering phenology as a settlement cue for migrating birds

Journal of Animal Ecology, 2008
1. Neotropical migrant birds show a clear preference for stopover habitats with ample food supplies; yet, the proximate cues underlying these decisions remain unclear. 2. For insectivorous migrants, cues associated with vegetative phenology (e.g. flowering, leaf flush, and leaf loss) may reliably predict the availability of herbivorous arthropods. Here

Begonia quadricornualata sp. nov. (Begoniaceae) from India

Nordic Journal of Botany, EarlyView.
A new species of Begonia L. (Begoniaceae) belonging to sect. Platycentrum is described from the Papum Pare District of Arunachal Pradesh, India. This new species is distinguished by its dense, long, red to brown hispid hairs on the adaxial leaf surface of female plants, caducous stipules and bracts, and solitary‐flowered female inflorescence ...

Predicting reproductive phenology of wind-pollinated trees via PlanetScope time series

Science of Remote Sensing
Airborne pollen triggers allergic reactions, which can have public health consequences. Accurate airborne pollen concentration modeling and prediction rely on understanding plant reproductive phenology, particularly the timing of flowering and pollen ...

Petrocosmea wentsaii sp. nov. (Gesneriaceae) from Guizhou, China

Nordic Journal of Botany, EarlyView.
Petrocosmea wentsaii M.Q. Han, Miao.M. Wang & Yan Liu, a new species from Guizhou, China, is described and illustrated. Petrocosmea wentsaii was found on damp walls in a huge limestone cave. It is most similar to Petrocosmea hexiensis S.Z. Zhang & Z.Y. Liu in the conformation of the corolla.

Lasianthus phucanhensis sp. nov. (Rubiaceae) from Vietnam

Nordic Journal of Botany, EarlyView.
Lasianthus phucanhensis (Rubiaceae), a new species from Hoa Binh Province, northwestern Vietnam, is described and illustrated. In addition, the opportunity is taken to review the typification of all Lasianthus spp. from Vietnam. Three lectotypes are selected for Lasianthus kamputensis Pierre ex Pit., Lasianthus dinhensis Pierre ex Pit.

Additions to the Acanthaceae of the Flora of Tropical East Africa: two new species from northern Kenya

Nordic Journal of Botany, EarlyView.
The new species Barleria kulalensis I.Darbysh. & Q.Luke and Dicliptera huriensis I.Darbysh. & Q.Luke are described and illustrated and their extinction risk is assessed provisionally. The former is based on Barleria sp. G of the Flora of Tropical East Africa (FTEA), with recent field observation and collection of this species from the foothills of ...

Estimation of true dates of various flowering stages at a centennial scale by applying a Bayesian statistical state space model.

PLoS ONE
Evaluation of long-term detailed cherry flowering phenology is required for a deep understanding of the sensitivity of spring phenology to climate change and its effect on cultural ecosystem services.

VARIATION IN THE FLOWERING PHENOLOGY OF AN EPIPHYTIC BROMELIAD ALONG AN ELEVATIONAL GRADIENT

Acta Biológica Colombiana, 2020
Elevational patterns in flowering phenology have been reported for trees, shrubs and herbs. However, for vascular epiphytes that rely on atmospheric sources for humidity and nutrients, and depend on phorophyte microhabitat, elevational patterns of ...
