SECONDARY POLLEN PRESENTATION, PSYCHOPHILY AND ANEMOCHORY IN Lagascea mollis Cav. (ASTERACEAE)

Biotropia: The Southeast Asian Journal of Tropical Biology, 2017
Information on pollination ecology and seed dispersal aspects is essential to understand sexual reproduction in Lagascea mollis Cav. The study was aimed at providing details of pollen presentation system, pollination syndrome, pollinators and seed ...

Pump mechanism, secondary pollen presentation, psychophily and anemochory in Emilia sonchifolia (L.) DC. (Asteraceae)

Journal of BioScience and Biotechnology, 2017
Emilia sonchifolia flowers profusely during August-November. The plant produces capitulum inflorescence with only disc florets presenting nectar and pollen as rewards.

Entomophily, ornithophily and anemochory in the self-incompatible Boswellia ovalifoliolata Bal. & Henry (Burseraceae), an endemic and endangered medicinally important tree species

Journal of Threatened Taxa, 2012
Boswellia ovalifoliolata (Burseraceae) is a narrow endemic and endangered deciduous tree species. Its flowering, fruiting and seed dispersal events occur in a leafless state during the dry season.

Temporal dioecism, melittophily and anemochory of Wendlandia glabrata (Rubiaceae) [PDF]

TAPROBANICA: The Journal of Asian Biodiversity, 2013
Wendlandia glabrata is a massive bloomer during February–March. Floral characteristics such as diurnal anthesis, white coloured, odorless, tubular flowers with deep seated sucrose-rich nectar conform to psychophily. Nectar is a source of essential and non-essential amino acids for butterflies, inconsistent foragers due to nectar traces in open flowers.

Anemochory of diapausing stages of microinvertebrates in North American drylands [PDF]

Freshwater Biology, 2019
Abstract Dry, ephemeral, desert wetlands are major sources of windblown sediment, as well as repositories for diapausing stages (propagules) of aquatic invertebrates. Zooplankton propagules are of the same size range as sand and dust grains. They can be deflated and transported in windstorm events. This study provides evidence that dust storms aid in

A phylogeographic study of the stoneplantConophytum(Aizoaceae; Ruschioideae; Ruschieae) in the Bushmanland Inselberg Region (South Africa) suggests anemochory

Systematics and Biodiversity, 2019
The Bushmanland Inselberg Region (BIR) of South Africa provides an ideal system to study population interactions, as these inselbergs function as islands of Succulent Karoo surrounded by Nama Karoo...

Monoecy, anemophily, anemochory and regeneration ecology of Hildegardia populifolia (Roxb.) Schott. & Endl. (Malvaceae), an economically important endemic and endangered dry deciduous tree species of southern Eastern Ghats, India

Journal of Threatened Taxa, 2014
Hildegardia populifolia est une espèce d'arbre en danger critique d'extinction. Tous les événements phénologiques - bouffées de chaleur, excrétion, floraison, dispersion des fruits - se produisent les uns après les autres pendant la saison sèche. Elle est morphologiquement andromonoïque mais fonctionnellement monoïque. Elle produit un rapport de fleurs

Wing and Pappus Appendages Decrease Seed Terminal Velocity: A Meta‐Analysis

Ecology and Evolution
Seed dispersal by wind regulates plant species distribution in natural vegetation and can be applied in forest management and aerodynamic engineering. The terminal velocity of seeds is a fundamental variable for predicting anemochory seed dispersal, but ...

Seed dispersal limitation causes negative legacy effect on restoration of grassland plant diversity on ski slopes [PDF]

Ecology and Evolution
Past forest use often has a long‐term negative impact on the recovery of the original plant composition of semi‐natural grasslands, which is known as a legacy effect.
