Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

open access: yes, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Multispectral Approach for Identifying Invasive Plant Species Based on Flowering Phenology Characteristics

open access: yesRemote Sensing, 2019
Invasive plant species (IPS) are the second biggest threat to biodiversity after habitat loss. Since the spatial extent of IPS is essential for managing the invaded ecosystem, the current study aims at identifying and mapping the aggressive IPS of Acacia

Combined effects of prohexadione‐calcium and growing environment on sweet cherry fruit quality and postharvest performance

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sweet cherry (Prunus avium L.) is a high‐value fruit crop, but its commercial success is often limited by poor pigmentation, reduced firmness, and short shelf life. This study evaluated the effects of preharvest applications of prohexadione‐calcium (1.5 L ha−1) on fruit quality and storage performance in lowland and hilly orchards ...

Effect of intra-urban temperature variation on tree flowering phenology, airborne pollen, and measurement error in epidemiological studies of allergenic pollen.

open access: yesScience of the Total Environment, 2019
Temperature gradients in cities can cause inter-neighborhood differences in the timing of pollen release. However, most epidemiological studies examining allergenic pollen utilize daily measurements from a single pollen monitoring station with the ...

Flowering phenology of Campanula on Mt Olynipos, Greece

open access: yesEcography, 2001
We studied the fowering phenology of the genus Campanula (represented by nine species) along the elevation gradient of Mt Olympos (Greece) in order to assess whether there are elevation patterns at the genus level and whether these relate to patterns previously observed along such gradients at the community level.

Contrasted habitat selection among Eurasian curlew populations according to landscape heterogeneity and breeding stage

open access: yesThe Journal of Wildlife Management, EarlyView.
This study aimed to quantify the spatio‐temporal use of breeding environments by the Eurasian curlew in 5 contrasting agricultural landscapes. To this end, 64 individuals were tagged with GPS devices to assess their space use according to their breeding stages and define their foraging habitat selection.

Interactive Effects of Arbuscular Mycorrhizal Fungi and Copper Stress on Flowering Phenology and Reproduction of Elsholtzia splendens.

open access: yesPLoS ONE, 2015
Plant responses to heavy metal contamination may depend on the presence of arbuscular mycorrhizal fungi (AMF). Elsholtzia splendens is an indicator species for the presence of copper (Cu) mines because both its flowering phenology and reproduction are ...
