Abstract In recent years, an extended body of literature has focused on the importance either temporal or spatial dynamics in shaping structure interacting plant and pollinator communities. This improvement from a previously static aggregated perspective allowed us to understand many ecological processes that shape community assembly. However, fewer are studies have simultaneously dynamics, even those collect data across different habitat types assess generality their findings. Here, we used dataset collected weekly throughout full flowering season for two consecutive years within contrasting N SW Spain: mountain grassland area understory sparse pine forests. We evaluated species interaction persistence through space time, fidelity, turnover patterns composition while providing potential mechanistic explanation observed. Our results show although generalization does not explain persistence, moderately generalist showing greatest fidelity subset they visit time. Further, find time is mostly driven by changes composition, it rewiring resulting indirect competitive interactions between species. help shed light mechanisms driving assembly beyond niche neutral adding within‐trophic‐level can modify preferences.

Current methods for studying the effects of climate change on plants and pollinators can be grouped into two main categories. The first category involves using species distribution models (SDMs) to generate habitat suitability maps, followed by applying scenarios predict future separately. second constructing interaction matrices between then either randomly removing or selectively generalist specialist species, as a way estimate how might affect plant–pollinator network. primary limitation approach is that it examines plant pollinator distributions separately, without considering their interactions within context pollination weakness does not accurately impacts, arbitrarily selects remove knowing which will truly shift, decline, increase in due change. Therefore, new needed bridge gap these while avoiding specific limitations. In this context, we introduced an innovative requires creation binary maps pollinators, based SDMs, both current periods. This step aligns with mentioned earlier. To assess network framework, consider co-overlapping geographic matrix. For purpose, developed Python program overlays generating matrices. These represent potential interactions, ‘0’ indicating no overlap ‘1’ where coincide same cell. As result, each cell study area, construct present means cell, analyze at least networks co-overlap. By comparing topology over time, infer fine spatial scale. We applied our methodology Chile case study, 187 171 resulting 2906 networks. evaluated could across cell-by-cell basis. Our findings indicated effect likely manifest more significantly through extinctions, rather than major changes topology.

. The study of ecological stability continues to fill the pages scientific journals almost seven decades after first ecologists initiated this line research. many advances in field have focused on understanding populations, communities or functions within single guilds trophic levels, with less research conducted across multiple levels and considering different interactions that relate species each other. Here, we review recent literature dimensions specifically plant-pollinator communities. We then focus one stability´s dimensions, temporal invariability, adapt an existing partitioning framework bridges invariability synchrony measures spatial scales organizational accommodate between plants their pollinators. Finally, use analyse plant reproductive success, it components pollinator populations communities, as well interactions, using a well-resolved dataset encompasses data for two years.

Pollinator choices when selecting flowers for nectar or pollen collection are crucial in determining the effectiveness of pollination services provided to plants. From plant's perspective, this is a phenomenon shaped by factors at both species‐ (e.g. pollinator density and flower morphology) community‐level, including diversity plant competition pollinators. At species level, individual influenced foraging choices, identity, resulting flow within between species. In natural ecosystems, these coexist complex community, where various interactions can modify alter flows, giving rise community‐level effectiveness, less explored aspect effectiveness. This study investigates drivers across two areas flowering seasons. It also assesses received different species, considering indirect plants through shared pollinators evaluating their impact on reproductive success. Our results show that determinants consistent habitats, with floral constancy abundance playing pivotal roles all sites. Foraging shift throughout season as composition changes, significantly impacting The overlap service use individuals same decreases fruit set, whereas sharing other increases set. support significant, positive biodiversity–ecosystem functioning associations driven richness, suggesting fosters facilitative rather than competition. likely more stable supplies under high conditions existence mechanisms mitigate negative impacts heterospecific deposition.
