“…The availability of flowers within a foraging patch is dynamic across time and is affected by change in micro-and macroclimatic conditions and the spatial heterogeneity of the landscape, with differences in light exposure which leads to changes in the growth and flowering phenology of plants (Alsanius et al, 2017;Ogilvie and Forrest, 2017;Swierszcz et al, 2019). These effects are easily illustrated in urban environments, where plants grow in small, heterogenous patches that are often located near anthropogenic structures such as roads and buildings, which create a variety of microclimatic conditions, resulting in differences in the growth and abundance of floral species (Habel et al, 2018;Jung et al, 2020). As such, some pollinators in highly fragmented urban environments may face favorable conditions for foraging on diverse flowers (Rollings and Goulson, 2019;Ropars et al, 2019;Staab et al, 2020;Tew et al, 2021).…”

Insect pollinators are affected by the spatio-temporal distribution of floral resources, which are dynamic across time and space, and also influenced heavily by anthropogenic activities. There is a need for spatial data describing the time-varying spatial distribution of flowers, which can be used within behavioral and ecological studies. However, this information is challenging to obtain. Traditional field techniques for mapping flowers are often laborious and limited to relatively small areas, making it difficult to assess how floral resources are perceived by pollinators to guide their behaviors. Conversely, remote sensing of plant traits is a relatively mature technique now, and such technologies have delivered valuable data for identifying and measuring non-floral dynamics in plant systems, particularly leaves, stems and woody biomass in a wide range of ecosystems from local to global scales. However, monitoring the spatial and temporal dynamics of plant floral resources has been notably scarce in remote sensing studies. Recently, lightweight drone technology has been adopted by the ecological community, offering a capability for flexible deployment in the field, and delivery of centimetric resolution data, providing a clear opportunity for capturing fine-grained information on floral resources at key times of the flowering season. In this review, we answer three key questions of relevance to pollination science – can remote sensing deliver information on (a) how isolated are floral resources? (b) What resources are available within a flower patch? And (c) how do floral patches change over time? We explain how such information has potential to deepen ecological understanding of the distribution of floral resources that feed pollinators and the parameters that determine their navigational and foraging choices based on the sensory information they extract at different spatial scales. We provide examples of how such data can be used to generate new insights into pollinator behaviors in distinct landscape types and their resilience to environmental change.

This study was carried out to assess the carbon budget of local governments in South Korea. The carbon budget was obtained from the difference between net ecosystem productivity (NEP) that the natural ecosystem displays, and carbon dioxide emissions calculated from energy consumption in each local government. NEP was obtained from the difference between net primary productivity, measured by an allometric method, and soil respiration, measured with EGM-4 in natural forests and artificial plantations. Heterotrophic respiration was adjusted to 55% level of the total soil respiration based on existing research results. A field survey to obtain information for components of the carbon cycle was conducted in Cheongju (central Korea) and Yeosu (southern Korea). Pinus densiflora, Quercus acutissima, and Quercus mongolica (central Korea) and P. densiflora and Q. acutissima (southern Korea) forests were selected as the natural forests. Pinus rigida and Larix kaempferi (central Korea) and P. rigida (southern Korea) plantations were selected as the artificial plantations. Vegetation types were classified by analyzing LandSat images by applying a GIS program. CO2 emissions were the highest in Pohang, Gwangyang, and Yeosu, where the iron and the petrochemical industrial complexes are located. CO2 emissions per unit area were the highest in Seoul, followed by Pohang and Gwangyang. CO2 absorption was the highest in the Gangwon province, where the forest area ratio to the total area is the highest, and the lowest in the metropolitan areas such as Seoul, Incheon, Daegu, Daejeon, and Gwangju. The number of local governments in which the amount of absorption is more than the emission amount was highest in Gangwon-do, where 10 local governments showed a negative carbon budget. Eight, seven, five, five, three, and three local governments in Gyeongsangbuk-do, Jeollanam-do, Gyeongsangnam-do, Jeollabuk-do, Gyeonggi-do, and Chungcheongbuk-do, respectively, showed a negative carbon budget where the amount of carbon absorption was greater than the emission amount. The carbon budget showed a very close correlation with carbon emission, and the carbon emission showed a significant correlation with population size. Moreover, the amount of carbon absorption showed a negative correlation with population size, population density, and non-forest area, and a positive correlation with the total area of the forest, coniferous forest area, and broad-leaved forest area. Considering the reality that carbon emissions exceed their absorption, measures to secure absorption sources should be considered as important as measures to reduce carbon emissions to achieve carbon neutrality in the future. As a measure to secure absorption sources, it is proposed to improve the quality of existing absorption sources, secure new absorption sources such as riparian forests, and efficiently arrange absorption sources.

“…Changes in climate conditions influence the energy and time budgets of individual organisms and thus can directly alter the timing of such events. Therefore, phenology is utilized as a valuable tool for diagnosing the biological impacts of climate change [8,18]. Climate changes may also influence phenology indirectly, as organisms use environmental cues, such as temperature or rainfall, to regulate the timing of specific events within their annual cycle [76].…”

“…In the phenological study, urban areas represent important study fields because their warmer conditions allow for an assessment of the future potential impacts of climate change on plant development [128] UHI-induced increases in temperature can affect vegetation phenology both within and around cities [49]. Lee et al [129] and Jung et al [18] reported that abnormal shoot growth appeared more frequently, and shoot length was longer, in the hotter urban center than in the urban fringe or the suburban greenbelt and the frequency of abnormal shoots and their lengths were closely correlated with the urbanized ratio (positively) and with the vegetation cover of land expressed as NDVI (Normalized difference vegetation index; negatively) in Seoul. A study carried out by Zipper et al [51] showed that the length of the urban growing season in Madison, Wisconsin of the USA is approximately five days longer than in the surrounding rural areas, and the UHI impacts on growing season length are relatively consistent from year to year.…”

“…Many of those studies have reported a correlation between earlier spring phenology and rising temperature but have showed different effects on the end of the growing season [1,[10][11][12][13][14][15]. Therefore, spring phenology is the most indisputable monitoring tools for the seasonality of plant species [5,13,[16][17][18]. Spring phenology is thought to greatly affect the productivity and carbon budget of temperate and boreal ecosystems [17,19].…”

This study aims to monitor spatiotemporal changes of spring phenology using the green-up start dates based on the accumulated growing degree days (AGDD) and the enhanced vegetation index (EVI), which were deducted from moderate resolution imaging spectroradiometer (MODIS) land surface temperature (LST) data. The green-up start dates were extracted from the MODIS-derived AGDD and EVI for 30 Mongolian oak (Quercus mongolica Fisch.) stands throughout South Korea. The relationship between green-up day of year needed to reach the AGDD threshold (DoYAGDD) and air temperature was closely maintained in data in both MODIS image interpretation and from 93 meteorological stations. Leaf green-up dates of Mongolian oak based on the AGDD threshold obtained from the records measured at five meteorological stations during the last century showed the same trend as the result of cherry observed visibly. Extrapolating the results, the spring onset of Mongolian oak and cherry has become earlier (14.5 ± 4.3 and 10.7 ± 3.6 days, respectively) with the rise of air temperature over the last century. The temperature in urban areas was consistently higher than that in the forest and the rural areas and the result was reflected on the vegetation phenology. Our study expanded the scale of the study on spring vegetation phenology spatiotemporally by combining satellite images with meteorological data. We expect our findings could be used to predict long-term changes in ecosystems due to climate change.
