Phenology, which is mostly related to climate, plant, and animal’s life, is the study of cyclical and seasonal natural occurrences (Taylor and White, 2020). Climate change influences the phenology, local abundance and population dissemination of plants and pollinators (Hegland et al., 2009a). Numerous experts have gathered a wealth of data about how seasonal behavior in plants and animals is impacted by global change (Abrahms et al., 2023; Covert et al., 2023; Halupka et al., 2023; Harvey et al., 2023; Ozgul et al., 2023; Peñuelas and Filella, 2001; Root et al., 2005; Singh et al., 2023; Walther et al., 2001). The change in plant phenology affects not just the health of individual plants but also the living forms that depend on them. As a result of the cascade effects from the individual to the environment, phenological changes in plants can negatively affect demography (McKinney et al., 2012; Stucky et al., 2018; Wudu et al., 2023). Widespread phenological change additionally influence human prosperity through agriculture, tourism, and human wellbeing (García-Mozo, 2017; Liu et al., 2019; Minoli et al., 2019; Shen et al., 2022; Song, 2023). Ecological interactions are a crucial component in maintaining the diversity of life on Earth. Mutualistic interaction between species exists in every ecosystem, and plant-pollinator interactions are excellent examples of mutualism (Kawata and Takimoto, 2023; St-Onge et al., 2022). Approximately 85% of angiosperm plant species and 33% of the world's cultivated crops are pollinated by animals; insects play the largest part in this ecological service (Burkle, Marlin andKnight, 2013b; Buxton et al., 2022; Potts et al., 2016).
Response diversity is a phenomenon where differences in phenological shift rates are seen across several species within the same group. Because of this, there are mismatches between interacting species when the phenological overlap between them decreases (Cook, Wolkovich andParmesan, 2012; Primack et al., 2009). Despite the fact that precipitation also profoundly influences phenology by regulating soil moisture, it is thought that temperature is the primary factor causing the shift in phenoevents. Examples of such phenological mismatches may be found in a wide range of biological systems, mainly in temperate and arctic locations (Kudo and Ida, 2013; Post and Forchhammer, 2008; Yin et al., 2023). With the exception of a few isolated instances when plants and pollinators interact negatively, generalist plants and insect pollinators demonstrate generally similar rates of phenological progress in response to global warming because of their adaptable relationships (Bartomeus et al., 2011; Burkle, Marlin andKnight, 2013b; Ovaskainen et al., 2013). Because the plants that are the only source of food for herbivores in alpine locations are impacted by early or late flowering/ phenology changes, it eventually affects how they forage. In many cases, herbivores seem to be adapting to climate change more quickly than their host plants, which has modified the selection pressure and created unusual ecological connections in their new environments (de Sassi and Tylianakis, 2012; Hamann et al., 2021; Lu et al., 2013). Few experiments showed that 17–50% of pollinators were observed to be affected due to disruption in food supply and temporal mismatch changing the pollinator’s demography (Memmott et al., 2007a; Ren et al., 2020).
Bibliometric analysis referred as quantitative and qualitative evaluation of the published literature in a particular research area by using mathematical and statistical tools. Bibliometric analysis is a useful technique for providing an overview of national and global contributions of the available literature in a specific field, and finding research gaps that may be addressed in future studies (Ellegaard and Wallin, 2015). Throughout recent years, various examinations have led bibliometric researches in different scholarly subjects (Belter, 2015; Semwal et al., 2023). Rather than comprehensive reviews, which endeavor to dissect a specific examination issue in few set of publications, bibliometric analysis give a total assessment of the writing in a specific region (Møller and Myles, 2016). This study intends to gain insight into the research trends on climate change impact on plant-pollinator interactions and provide references for future research by examining the worldwide correlations between the research trends and hotspots in this field. In addition, policymakers and funding organizations can decide where to allocate resources by obtaining information about current research trends and hotspots in the field.
