pollination,   etc   ; floral characteristics; niches; pollinators;     Show all 4 Subjects
Abstract:
... Ecological niches are crucial for species coexistence and diversification, but the niche concept has been underutilized in studying the roles of pollinators in plant evolution and reproduction. Pollination niches can be objectively characterized using pollinator traits, abundance, and distributions, as well as network topology. We review evidence that floral traits represent adaptations to pollina ...

Abstract:
... Reports on whether typical apertures occur in pollen of Althenia (Potamogetonaceae) are controversial. The question is of interest because relatively few submerged aquatic angiosperms possess localised apertures, and the phylogenetic placement of Potamogetonaceae suggests an ancestral nature for the inaperturate condition in this family. Pollen grains from two Eurasian-African Althenia species, A. ...

Abstract:
... The function of orbicules has been a matter of speculation for a long time and until now no satisfactory answer has been put forward. We propose two hypotheses that could contribute to the elucidation of their function: (1) that anemophilous and ‘buzz pollination’ species have microechinate orbicules; and (2) that microechinate orbicules are advantageous for pollen release in both pollination mode ...

Abstract:
... Related plants are often hypothesized to interact with similar sets of pollinators and herbivores, but this idea has only mixed empirical support. This may be because plant families vary in their tendency to share interaction partners. We quantify overlap of interaction partners for all pairs of plants in 59 pollination and 11 herbivory networks based on the numbers of shared and unshared interact ...

Abstract:
... Predicting concentrations of pollen is of great importance both for patients and for public health institutions. In this paper, we present a forecasting approach which relies on data and makes no assumptions on the underlying phenomena affecting the plants and the pollination process. Machine learning is used to build a model and to select the most important variables for prediction. Through nonpa ...

To expand the availability of intergeneric allopolyploids between Brassica rapa and Raphanus sativus beyond BB#1, a stable xBrassicoraphanus koranhort (baemoochae) cultivar (2n = 38, aAARR genome), we developed four intergeneric hybrids between different materials from B. rapa and R. sativus. These hybrids produced neither self-pollinated seeds nor embryos in microspore culture. The hybrids, howev ...

Abstract:
... Growing evidence of global declines in pollinator abundance and diversity has raised concerns about the resilience of pollination systems. When subjected to stressors, each nested component of the pollination system (communities, populations, and colonies) can respond in either a smooth linear fashion, or in an abrupt nonlinear manner. Threshold and tipping point responses to stress are of particu ...

Abstract:
... The distance travelled by pollinators between successive flower visits can affect the quality of pollen transferred among plants. In cropping environments, especially monoculture systems, pollinators that travel between plants or rows may increase cross-pollination and consequently crop yield. However, the most commonly utilized crop pollinator, Apis mellifera L., tends to forage consecutively on ...

Most research has focused on FFD whereas LFD, FD and second flowering events were neglected although they are crucial events. To assess whether flowering patterns change species-specifically with changing abiotic conditions and whether these are re ...

Abstract:
... Flowers have developed different strategies to attract pollinators through visual or olfactory signals. Most flowers offer pollinators a reward (e.g. nectar and pollen) for the pollination service. However, one‐third of Orchidaceae have been shown not to provide a reward. Calanthe are terrestrial orchids distributed throughout China, Nepal, Japan and tropical Asia. Despite its high diversity, the ...
