Phyllocephalum keralense (Asteraceae) a new species from southern Western Ghats of Kerala, India

Nordic Journal of Botany, EarlyView.
A new species of Phyllocephalum is described and illustrated from Palakkad district of Kerala, India. The new species shows similarity to P. rangacharii but differs with respect to key floral traits, viz. ovoid shape of the capitula, involucral bracts in 3 series, inflated receptacle and ovoid 6‐ribbed ovary with 5–6 densely barbellate pappus setae ...

Yearly fluctuations of flower landscape in a Mediterranean scrubland: Consequences for floral resource availability.

PLoS ONE, 2018
Species flower production and flowering phenology vary from year to year due to extrinsic factors. Inter-annual variability in flowering patterns may have important consequences for attractiveness to pollinators, and ultimately, plant reproductive output.

Escape from floral herbivory by early flowering in Arabidopsis halleri subsp. gemmifera [PDF]

, 2018
Natural selection on flowering phenology has been studied primarily in terms of plant-pollinator interactions and effects of abiotic conditions. Little is known, however, about geographic variation in other biotic factors such as herbivores and its ...

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

Tetrataenium paikadae (Apiaceae), a new species from the Western Ghats, India

Nordic Journal of Botany, EarlyView.
A new species, Tetrataenium paikadae C.Rekha, Manudev & Prasanth (Apiaceae), is described from the State of Kerala, India. The new species is characterised by its hirsute to hispid stems, broadly ovate or rounded leaflets, long petioles with hirsute leaf sheaths, tomentose rays, symmetric flowers, ovate‐lanceolate involucel bracteoles, and mericarp ...

Reinstatement and generic reassignment of Phyllanthus asteranthos Croizat (Phyllanthaceae) based on living plant observations and specimen analysis

Nordic Journal of Botany, EarlyView.
Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Urbanization, environmental stabilization and temporal persistence of bird species: A view from Latin America [PDF]

, 2018
Background. A scarcely studied consequence of urbanization is the effect of temporal stabilization of the environment on bird communities. This alteration is thought to dampen environmental variations between day and night, seasons and years, promoting a

Reinstatement of the name Anisochilus eriocephalus Benth. (Lamiaceae) supported by micromorphological and molecular data

Nordic Journal of Botany, EarlyView.
In 2019, A. J. Paton et al. proposed a new taxonomic combination, transferring Anisochilus carnosus (L.f.) Wall. ex Benth. to Coleus strobilifer (Benth.) A.J.Paton, and including Anisochilus eriocephalus Benth. within this broader circumscription.

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 ...

Reproductive biology of "Helianthemum apennium" (L.) Mill. and "H. caput-felis" Boiss. (Cistaceae) from Mallorca (Balearic Island, Spain) [PDF]

, 1997
El estudio de la biología reproductiva de poblaciones naturales de Helianthemum apenninum y H. caput-felis en Mallorca ha demostrado que son básicamente entomófilos, aunque también producen numerosos frutos por auto-polinización. Las flores de H.
