Types of Pollination: Abiotic vs. Biotic Various types of pollination have also been identified based on the vectors of pollen grains or agents of pollination. These pollinators are described under two main classifications: (1)abiotic, i.e, nonliving pollinators, and (2)biotic, i.e., living...

Ecosystem services such as pollination and biocontrol may be severely affected by emerging nano/micro-plastics (NMP) pollution. Here, we synthesize the little-known effects of NMP on pollinators and biocontrol agents on the organismal, farm and landscape scale. Ingested NMP trigger organismal changes...
Up to today, our knowledge of many crop-pollinator systems (e.g. for cacao, oil palm) is not exhaustive, including knowledge gaps on the identity of pollinator agents, pollination ecology, and how land-use affects pollinator species and communities (Li et al., 2019; Senapathi, Goddard, ...
Bat-pollinated, Chiropterophilae. - A Freycinetia, native of Java, and a species of Bauhinia in Trinidad are visited by bats which transfer the pollen. b. Bird-pollinated, Ornithophilae Humming-birds and honeysuckers are agents of pollination in certain tropical plants; they visit the ...
Wind and water are the abiotic agents of pollination. Wind pollination is the dominant type of abiotic pollination, comprising perhaps 98 percent of all known examples and prevailing in several families: Gramineae, Cyperaceae, Juncaceae, and within the orders of Amentiferae and in Urticales. In ...
. Protection from SNP apoptosis by UO126 was also confirmed by immune blotting Conclusions: We show for the first time that: ERK activation, frequently found in many cancer types, sensitize melanoma cells to SNP-mediated cell death. Athough inhibiting ERK activation enhances tumor cell response ...

Types of Self-Pollination and Cross-Pollination 1. Autogamy Autogamy is a kind of self-pollination. In this, microspores move from the anther to the stigma within the same flower. Requirements for autogamy: When the pollen is discharged, the stigma should be prepared to take it. ...
