“…In contrast, our results showed that insect assemblages vary spatially and temporally and may be shaped by beekeeping activities, to some degree. Apart from human activity, including beekeeping, also other factors, such as the immediate surroundings, type of habitat and population size of P. caeruleum , as well as the presence and abundance of other groups of insects, and meteorological conditions in a given year, probably influenced the spatial and temporal diversity of insects visiting P. caeruleum flowers ( Somme et al, 2014 ; Paajanen and Cronk, 2020 ; Rohde and Pilliod, 2021 ).…”

Spatiotemporal Variations in Seed Set and Pollen Limitation in Populations of the Rare Generalist Species Polemonium caeruleum in Poland

A vast majority of angiosperms are pollinated by animals, and a decline in the number and diversity of insects often affects plant reproduction through pollen limitation. This phenomenon may be particularly severe in rare plant species, whose populations are shrinking. Here, we examined the variability in factors shaping reproductive success and pollen limitation in red-listed Polemonium caeruleum L. During a 5-year study in several populations of P. caeruleum (7–15, depending on year), we assessed the degree of pollen limitation based on differences in seed set between open-pollinated (control) and hand-pollinated flowers. We analysed the effects of flower visitors, population size, and meteorological data on plant reproductive success and pollen limitation. Our study showed that pollen limitation rarely affected P. caeruleum populations, and was present mainly in small populations. Pollen limitation index was negatively affected by the size of population, visitation frequency of all insects, and when considering the visitation frequency of individual groups, also by honeybee visits. Seed production in control treatment was positively influenced by the population size, average monthly precipitation in June and visits of hoverflies, while visits of honeybees, average monthly temperature in September, and average monthly precipitation in August influenced seed production negatively. As generalist plant P. caeruleum can be pollinated by diverse insect groups, however, in small populations their main visitors, the honeybees and bumblebees, may be less attracted, eventually leading to the disappearance of these populations. In pollination of P. caeruleum managed honeybees may play a dual role: while they are the most frequent and efficient flower visitors, their presence decreases seed set in open-pollinated flowers, which is most probably related to efficient pollen collection by these insects.

Global warming has been predicted to cause big changes in terrestrial natural ecosystems and processes. Forests, being a part of terrestrial ecosystems, help in the regulation of biogeochemical processes and functions. Insect pollination is one function that is useful to the forest ecosystem as well as to the associated agroecosystems. Climate change is thought to be a principal factor that can influence the activities, distribution, and abundance of insect pollinators dwelling in the forest. Overall, elevated temperature level could affect the insect pollinators present in the forests. The present paper reviews the possible impact of climate change on insect pollination services provided by the forests, highlighting the importance of insect pollinators present in the forest, the dependence of linked agro-ecosystems on the forest, and various indicators of climate change with the species present in the forest. The paper finally concludes with some key recommendations for the conservation of forest insect pollination function with respect to climate change.

“…Toward this aim, we require accurate and continuous observations of plant phenology (e.g., flowering, leaf flush, leaf coloring, and leaf fall), which serve as proxies of the responses of organisms and ecosystems to the environment (Tang et al, 2016;Piao et al, 2019), and of land-cover and land-use change. Data on plant phenology, and land-cover and land-use change help to explain the spatiotemporal variability of ecosystem properties (e.g., photosynthesis and evapotranspiration, carbon stocks and flows, the land surface's albedo, and energy balances; Penþuelas et al, 2009;Kumagai et al, 2013;Richardson et al, 2013;Wu et al, 2016), emission of biogenic volatile organic compounds (BVOCs; Penþuelas et al, 2009;Richardson et al, 2013;IPCC, 2021), cultural ecosystem services (e.g., festivals and recreation opportunities; Sakurai et al, 2011;Sparks, 2014;Nagai et al, 2019), regulating ecosystem services (e.g., pollinator abundances and pollination; Lautenbach et al, 2012;Rohde and Pilliod, 2021), environmental changes in various habitats (Muraoka et al, 2012;Gray and Ewers, 2021), and biodiversity conservation (Morisette et al, 2009;Secades et al, 2014;Morellato et al, 2016). Phenological mismatch between plants and their animal pollinators and consumers caused by the changes of the timing of each phenology due to climate change, reduces the biodiversity (Visser and Gienapp, 2019; Secretariat of the Convention on Biological Diversity, 2020).…”

Recent advances in satellite-borne optical sensors led to important developments in the monitoring of tropical ecosystems in Asia, which have been strongly affected by recent anthropogenic activities and climate change. Based on our feasibility analyses conducted in Indonesia in Sumatra and Sarawak, Malaysia in Borneo, we discuss the current situation, problems, recent improvements, and future tasks regarding plant phenology observations and land-cover and land-use detection. We found that the Multispectral Instrument (MSI) on board the Sentinel-2A/2B satellites with a 10-m spatial resolution and 5-day observational intervals could be used to monitor phenology among tree species. For the Advanced Himawari Imager (AHI) on board the Himawari-8 geostationary satellite with a 1,000-m spatial resolution and 10-min observational intervals, we found that the time-series in vegetation indices without gaps due to cloud contamination may be used to accurately detect the timing and patterns of phenology among tree species, although the spatial resolution of the sensor requires further improvement. We also found and validated that text and pictures with geolocation information published on the Internet, and historical field notes could be used for ground-truthing land cover and land use in the past and present time. The future development of both high frequency (≤ 10 min) and high spatial resolution (≤ 10 m) optical sensors aboard satellites is expected to dramatically improve our understanding of ecosystems in the tropical Asia.
