Since the launch of Ecology Letters in 1998, the field of Pollination Ecology has changed considerably in its focus. In this review, we discuss the major discoveries across the past two decades. We quantitatively synthesise the frequency by which different concepts and topics appeared in the peer-reviewed literature, as well as the connections between these topics. We then look forward to identify pressing research frontiers and opportunities for additional integration in the future. We find that there has been a shift towards viewing plant-pollinator interactions as networks and towards understanding how global drivers influence the plants, pollinators and the ecosystem service of pollination. Future frontiers include moving towards a macroecological view of plant-pollinator interactions, understanding how ecological intensification and urbanisation will influence pollination, considering other interactions, such as plant-microbe-pollinator networks, and understanding the causes and consequences of extinctions. Pollination Ecology is poised to advance our basic understanding of the ecological and evolutionary factors that shape plant-animal interactions and to create applied knowledge that informs conservation decision making.

“…As the activity of the microorganisms turns organic to mineral matter, thereby increasing the amount of nutrients available for the plants, disturbances caused by contaminants that limit microbial activity can lead to decreases in plant growth, reproduction, and highquality seed production. In sum, mine exploitation and resulting contamination can have a signi cant negative impact above-and belowground, affecting growth, owering and pollination, on plant seed production and quality (Booth et al 2003), and ultimately survival and regeneration (Waser et al 2017).…”

Destructive mining operations are affecting large areas of natural ecosystems, especially in arid lands.The present study aims at investigating the impact of iron mine exploitation on vegetation and soil in Nodoushan (Yazd province, central Iran). Based on the dominant wind, topography, slope, vegetation and soil of the area, soil and vegetation parameters close to the mine were recorded and analyzed according to the distance from the mine. In order to obtain the vegetation cover, a transect and plot on the windward and leeward side of the mine, with 100 m intervals and three replicates at each sampling location was used, yielding 96 soil samples. The amount of dust on the vegetation, the seed weight and seed germination rate of Artemisia sp. as the dominant species within the area, and the soil microbial respiration were measured. The relationship between vegetation cover and distance from the mine was not linear, which was due to an interplay between pollution from the mine and local grazing, while other factors did increase or decrease linearly. The results showed that, as the distance from the mine increased, the weight of 1000 seeds of Artemisia sp. was signi cantly increased from 271 to 494 mg and seed germination rate and soil microbial respiration were signi cantly increased from 11.7 to 48.4 % and from 4.5 to 5.9 mg CO 2 g − 1 soil day − 1 respectively, while the amount of dust signi cantly decreased from 43.5 to 6 mg (g plant) −1 between the distance of 100 to 600 m from the mine in the leeward direction. A similar trend was observed in the windward side, though negative effects were lower compared to the same distance along the leeward sample locations. The direct and indirect effects on plant growth and health from mining impacts generally decreased linearly with increasing distance from the mine, up to at least 600 m. Our study serves as a showcase for the potential of bio-indicators as a cost-effective method for assessing impacts of mining activities on the surrounding environment.

“…During the dry winter season, when trees are dormant, because of the reduced solar radiation reaching the orchard floor in combination with a reduced wind speed, the irrigation input was greatly reduced ( Table 2 ). Another factor that could affect the longevity of the female flowers and interfere with the pollination process, especially in field condition, was the presence of dust ( Waser et al, 2017 ; Zhang et al, 2019 ). Hazelnut is a wind pollinated plant and the sticky style exposed to air can be polluted by dust.…”

Hazelnut (Corylus avellana L.) is one of the most appreciated nut crops, which is motivating the cultivation outside its historical production areas. Despite that, there is still limited knowledge about the floral biology of the species and its developmental fruiting stages under different environments. Adverse climatic conditions can threaten the pollination process and fruit development. In South Africa, the deciduous fruit industry identified the net shading as a tool to mitigate the effects of unfavorable abiotic events. The objective of this work was to investigate the effects of photo-selective nets on the pollination process and nut development of C. avellana. Mature hazelnut trees were maintained under netting and compared with the ones in open field. Microscopic examination of female flower and developing nuts were conducted in order to observe the pollen tube growth and the pattern of disodium fluorescein transport into the funiculus and ovule. The results showed differences in pollen tubes growth and timing between the treatments. Generally, trees under nets showed higher rate in pollen tubes developing and reaching the base of the style. On the contrary, the tests carried out in open field showed a higher ratio of pollen tubes arrested in the style. The results also indicated differences in ovules abortion. Developing fruits that showed an interruption point at the funicle level or at junction point of the ovule were classified as aborting fruits (blank nuts at harvest time). A higher rate of abortion was detected in open field compared to the plants under netting. In conclusion, the shade nets influenced the pollen tube growth and the nut development, principally due to micro-climate modification. Therefore, further investigations are needed to analyze the influence of light spectra and to determine the sustainability of photo-selective nets over several years.
