Background Functional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, widely used ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species that at best only weakly associated with functions. Animal-mediated pollination is a key function and likely to be influenced by pollinator traits, but date no one has identified functional simple measure have good predictive power. Methods Here,...
There is increasing concern about the decline of pollinators worldwide. However, despite reports that pollinator declines are widespread, data scarce and often geographically taxonomically biased. These biases limit robust inference any potential crisis. Non-structured opportunistic historical specimen collection provide only source information which can serve as a baseline for identifying declines. Specimens historically collected preserved in museums not on where when species were...
Abstract Globally, plants display enormous variation in life‐history strategies and trait combinations. However, evidence suggests that evolutionary physiological constraints limit the number of plant ecological strategies. Although there have been recent advances understanding correlations among traits, reproductive traits are rarely considered, despite their key role shaping interactions with pollinators. Here, using a global dataset 18 for 1506 species, we investigate spectrum flowering...
1. The decomposition of biological material produces a plethora volatile organic compounds ( VOC s), which are implicated in the foraging behaviour coprophagous and necrophagous insects. Dung beetles C oleoptera: S carabaeidae: carabaeinae) have an acute olfactory system used to locate food resources. Accordingly, identification resource s potentially location is integral understanding dung beetle ecology. 2. In this study, emissions from carrion native introduced animals N ew Z ealand were...
Abstract Globally, conversion of natural habitat to agricultural land is a primary driver declines in critical ecosystem services, including pollination. However, exotic species are often well‐adapted human‐modified environments and could compensate for services that lost when native decline. We measured pollination (pollen delivery stigma) provided by wild insects mass flowering crop, pak choi Brassica rapa at 12 sites across gradient increasing use (agricultural expansion) New Zealand....
Abstract Aim Understanding how climate conditions influence plant–pollinator interactions at the global scale is crucial to understand pollinator communities and ecosystem function respond environmental change. Here, we investigate whether drives differences in network roles of main insect orders: Diptera, Coleoptera, Lepidoptera Hymenoptera. Location Global. Time period 1968–2020. Major taxa studied Methods We collated networks from 26 countries territories across five Köppen–Geiger zones....
Two main mechanisms may buffer ecosystem functions despite biodiversity loss. First, multiple species could share similar ecological roles, thus providing functional redundancy. Second, respond differently to environmental change (response diversity). However, function would be best protected when functionally redundant also show response diversity. This linkage has not been studied directly, so we investigated whether native and exotic pollinator with traits (functional redundancy) differed...
Abstract Worldwide, anthropogenic change is causing biodiversity loss, disrupting many critical ecosystem functions. Most studies investigating the relationship between and functioning focus on species richness, predominantly within context of productivity‐related Consequently, there limited understanding how other measures, such as evenness (the distribution abundance among species), affect complex multitrophic functions pollination. We explore effect function pollination using a controlled...
Pollination services from animals are critical for both crop production and reproduction in wild plant species. Accurately measuring the relative contributions of different animal taxa to pollination service delivery is essential identifying key pollinators. However, widely used measures pollinator effectiveness (e.g., single visit pollen deposition) may be inaccurate where strongly constrained by quality. Here, we test efficacy multiple visits performance a model species (apple, Malus...
Priority effects occur when the order of species arrival affects subsequent ecological processes. The that pollinator visit flowers may affect pollination through a priority effect, whereby first visitor reduces or modifies contribution visits. We observed floral visitation to blueberry from honeybees, stingless bees mixture both and investigated how (i) initial visits differed in duration later visits; (ii) sequences different taxa influenced fruit weight. Stingless visited for...
Tree pathogens threaten the survival of many forest foundation tree species worldwide. However, there is limited knowledge how dieback may other components ecosystems, such as soil biodiversity and associated ecosystem functions. Kauri ( Agathis australis ), threatened by root-borne pathogen Phytophthora agathidicida , are culturally ecologically significant that exert great influence on properties. We aimed to characterise mesofauna community structure energy fluxes in kauri forests assess...
Abstract Bees provide pollination services to managed and wild ecosystems but are threatened globally due multiple stressors, including exposure contaminants. Perfluorooctane sulfonate (PFOS) is a widely detected persistent contaminant that accumulates biomagnifies in food chains. In this effect study, small whole colonies of Apis mellifera (1000 bees) were exposed PFOS using purpose‐built cage system over 4‐week period. The concentrations provided bees sugar syrup at the environment,...
Flower visitors use different parts of the landscape through plants they visit, however these connections vary within and among land uses. Identifying which flower-visiting insects are carrying pollen, from where in landscape, can elucidate key pollen-insect interactions identify most important sites for maintaining community-level across We developed a bipartite meta-network, linking with occur in. used this to land-use types at site- landscape-scale (within 500 m site) conserving...

Plant life-history strategies are constrained by cost-benefit trade-offs that determine plant form and function. However, despite recent advances in the understanding of for vegetative physiological traits, little is known about reproductive economics how they constrain shape interactions with floral visitors. Here, we investigate these drive visitors using a dataset 17 traits 1,506 species from 28 plant-pollinator studies across 18 countries. We tested whether plant’s strategy predicts its...
<title>Abstract</title> Human pressures, particularly urbanisation and agricultural expansion, profoundly affect biodiversity by reshaping species functional trait distributions, with critical consequences for ecosystem resilience multifunctionality. Yet, the extent strength of these impacts across diverse taxa ecosystems remain poorly understood. Here, we analyse 160 spatial datasets, encompassing over 13,000 local communities nine major in freshwater terrestrial worldwide. Our results...
