Population‐level plant pollination mode is influenced by Quaternary climate and pollinators

چکیده
Patterns in ecology are the products of current factors interacting with history. Nevertheless, few studies have attempted to disentangle contribution historical and factors, such as climate change pollinator identity behavior, on plant reproduction. Here, we separate relative importance processes geographical patterns mating system tree species Curatella americana (Dilleniaceae). Specifically, asked following: (a) How do Quaternary affect system? (b) does abundance diversity relate (c) fruit/seed quantity quality C. americana? We recorded pollinators (richness, frequency, body size) performed pollination tests ten populations spread over 3,000 km Brazilian savannah. The frequency self-pollination absence was strongly influenced by climatic instability not present-day pollinators. In contrast, seed set from hand-cross natural were affected (especially large bees) temperature, indicating out-cross pollination. Two at Southern edge species’ distribution showed high level hand-cross-pollination flower visitation bees, but also a autogamy resulting recent colonization. Our results indicate that has favored autogamy, most likely reproductive insurance strategy facilitating colonization population maintenance time, while currently modulating cross-pollination.

Climate-driven spatial mismatches between British orchards and their pollinators: increased risks of pollination deficits
Understanding how climate change can affect crop-pollinator systems helps predict potential geographical mismatches between a crop and its pollinators, and therefore identify areas vulnerable to loss of pollination services. We examined the distribution of orchard species (apples, pears, plums and other top fruits) and their pollinators in Great Britain, for present and future climatic conditio...
متن کاملclimate change and pollinators
abstract this chapter describes how the climate change is potentially the mostsevere threat to pollinator biodiversity. mounting evidence demonstrates that therehave already been biotic responses to the relatively small climate changes that haveoccurred this century. pollinators such as birds, bees, butterflies, moths, flies, wasps,beetles bats and even mosquitoes are essential for food product...
متن کاملPollination syndromes in a specialised plant-pollinator interaction: does floral morphology predict pollinators in Calceolaria?
Pollination syndromes are defined as suites of floral traits evolved in response to selection imposed by a particular group of pollinators (e.g., butterflies, hummingbirds, bats). Although numerous studies demonstrated their occurrence in plants pollinated by radically different pollinators, it is less known whether it is possible to identify them within species pollinated by one functional pol...
متن کاملHairiness: the missing link between pollinators and pollination
BACKGROUND Functional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, traits are widely used in ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species that are at best only weakly associated with functions. Animal-mediated pollination is a key ecosystem function and is likely to be i...
