Phenological shifts of abiotic events, producers and consumers across a continent

Seasonality in Human Interest in Berry Plants Detection by Google Trends

“…Such a keyword with relatively clear associations with specific phenomena enables temporal and spatial variation in RSV to be validated with biological observation (Proulx et al, 2014). However, time series or statistics data usable for a validation source for the seasonal pattern of human interest in berry species were the indirect explanatory factor: for example, supply in the agricultural markets and retail stores, routine observation at botanical gardens or institutes (e.g., Roslin et al, 2021), and climate conditions affecting berry growth (e.g., Krebs et al, 2009;Nestby et al, 2019;Tahvanaian et al, 2019) in the target area. Event dates that cue people to make an internet search for berries (e.g., festivals featuring specific berries and announcement of wild berry harvesting periods from local government in Russia) are considered a regionally specific condition.…”

Synergistic effects of warming and eutrophication alert zooplankton predator–prey interactions along the benthic–pelagic interface

“…Warming has been shown to favor superior competitors for nutrients (Falkowski & Oliver, 2007) and alter species compositions (Winder et al, 2009; Yvon‐Durocher et al, 2010). Warming can also exert differential responses of organisms at different trophic levels (Hansson et al, 2013; Roslin et al, 2021; Thackeray et al, 2010; Yvon‐Durocher et al, 2010), which may alter interaction strengths and change consumer–resource dynamics (Vasseur & Mccann, 2005). Previous studies have suggested that changes in temperature can have strong effects on the termination of diapause and establishment of both rotifers and cyclopoid copepods, thereby affecting their phenology and abundances (Adrian et al, 2006; Diovisalvi et al, 2018; Gilbert, 2020; Winder & Schindler, 2004b; Zhang et al, 2018).…”

Temperature and nutrient conditions modify the effects of phenological shifts in predator-prey communities

“…The relative timing of phenologies within a community determines what species and stages co-occur and thus can interact directly, when interactions start, and how long they last (Yang and Rudolf 2010). However, the relative timing of phenologies naturally vary across time and space (Carter et al 2018, Rudolf 2018, Roslin et al 2021) and is further altered by ongoing climate change (Parmesan and Yohe 2003, Visser and Both 2005, Cohen et al 2018, Kharouba et al 2018). While recent studies indicate that these changes in the relative timing of phenologies can alter the outcome of interactions and change long-term conditions for persistence and coexistence (Rudolf 2019), we are still lacking a general understanding of how important the environmental context (e.g.…”

“…abiotic conditions) is for mediating the effects of phenological shifts. Yet environmental conditions vary across space and time (including climate change), and these differences are often (Visser and Holleman 2001, Durant et al 2007, Dijkstra et al 2011, Ovaskainen et al 2013, Cohen et al 2018), but not always (Roslin et al 2021), the driver of phenological shifts. Thus, elucidating how the effects of phenological shifts vary across environmental conditions is not only essential to understand community dynamics across heterogeneous landscapes, but also key to predict how they will change in the future with ongoing climate change.…”
