Abstract	Chronic anthropogenic disturbances and climate change have been recognized as drivers of biological reorganization across human‐modified tropical landscapes, also negatively affecting the reproductive output of some plant species. Here, we investigated to what extent these drivers affect the reproductive output of Cenostigma microphyllum, a disturbance‐adapted tree species endemic to the Caatinga dry forest. The production of flowers/inflorescence, fruits and seeds was estimated for 105 plants (≥3 cm diameter at soil height) across 11 forest stands (20 × 50 m each), covering gradients of chronic disturbances (e.g. goat and livestock herbivory; wood extraction; and removal of non‐timber forest products) and aridity at the Catimbau National Park. We documented that when the drivers were analysed in isolation, the fruit‐set was positively associated with increased wood extraction, and the fruit‐set and total number of seeds/plots were reduced under increasing aridity. We also verified a complex interaction between wood extraction and aridity emerged. In forest stands, the combination of high levels of aridity and wood extraction leads to a decrease in the fruit‐set and total number of seeds/plots. Conversely, the fruit‐set and total number of seeds/plots increased in stands exposed to lower aridity but high levels of wood extraction. Our results suggest that chronic disturbances and aridity affect plant fitness in a complex way including both negative and positive effects on attributes related to plant reproductive performance, which could result in both proliferation and population decline in the same landscape. Although C. microphyllum benefits from anthropogenic disturbances and is considered a disturbance‐adapted species, it apparently does not benefit from increases in aridity, which is an expected future scenario for the Caatinga dry forest.

Abstract	Climate change modifies geographic ranges, phenology, and biological interactions—key components of species ecological niche. Alterations in distribution ranges could decrease the size of the populations and thus threaten the persistence of the species. Here, we seek to test the Eltonian Noise Hypotheses (ENH), which states that biotic interactions do not affect species distribution at large geographical scales, using Tacinga palmadora (Cactaceae), an endemic species to the Caatinga dry forest in Brazil, as the case study. We first modeled the current distribution of T. palmadora and its pollinators, the hummingbird Chlorostilbon lucidus and the stingless bee Trigona spinipes, separately using only climatic variables. Then, we modeled T. palmadora current distribution using C. lucidus and T. spinipes distributions as input layers alongside the climatic variables. Afterwards, we projected the model to the future to predict climatic conditions for the year 2070 (average for 2061–2080), using optimistic (RCP4.5) and pessimistic (RCP8.5) greenhouse gas emission scenarios. We analyzed model performance and determined habitat suitability of the species for all models. In general, biotic interactions did not increase model performance and the best-supported models were the ones considering climatic variables only. We found that T. palmadora suitable habitats are most likely to be reduced by climate change. In this sense, our results supported the ENH and showed that T. palmadora may lose a part of its climatic envelope, already restricted by its endemism, generating negative cascade effects on the region.

Abstract	The spatial distribution of floral resources directly affects the foraging pattern of pollinators. In addition, plant–pollinator interactions are linked to a great diversity of visual, chemical, and morphological signals, which interfere with plant reproduction. Here, we aimed to understand how flower distribution of Jatropha mutabilis (Euphorbiaceae) affects the foraging behavior of its floral visitors. We hypothesized that an increase in the (i) number of flowering individuals, (ii) total number of open flowers, or (iii) floral display (number of open flowers/inflorescences) increases the number of floral visitors. The study was carried out in a Caatinga dry forest in Pernambuco, Brazil. The number of flowering individuals/plot, the total number of open flowers/plot, and the floral display/inflorescence/plot were counted in 37 plots. Those parameters were also analyzed separately for male and female flowers since the species is monoecious. We documented that the number of floral visits was positively correlated with the number of flowering individuals and the total number of open flowers/plot but did not correlate with floral display/inflorescence. We observed interactive effect of the number of open flowers/plot and floral display affecting visitors’ frequency, which was higher with both: increased number of open flowers/plot and lower floral display. Floral sex did not correlate with the analyzed parameters. Our findings show that plant-floral visitor interactions are sensitive to changes in the intraspecific number of open flowers/plot, independently of flower sex. High flower production scattered among individuals, as in Jatropha mutabilis, increases the chances of pollination and maintenance of plant species and floral visitors, which is especially important in seasonally dry tropical forests, such as the Caatinga dry forest.

Abstract	Ecological interactions in tropical ecosystems are being modified by chronic anthropogenic disturbances (CAD) and climate change. Pollination is a key mutualistic interaction that can be affected by disturbance and climate change due to alterations in the composition, diversity, and distribution of plants, floral resources, and pollinators. We tested if increasing CAD and aridity induces changes in pollen traits and female reproductive success of Tacinga palmadora, a self-compatible cactus that performs as an important food source for nectar-feeding and fruit-eating animals, in the Caatinga dry forest. The study was carried out in eight plots at the Catimbau National Park, northeastern Brazil. Each plot had a different level of disturbance and aridity, used as predictor variables against pollen traits (total pollen production, pollen viability, and pollen-ovule ratio) and female reproductive success (fruit- and seed-set by both open and spontaneous self-pollination) in generalized linear models. All pollen traits were negatively associated with increasing CAD and aridity intensity, while the seed- and fruit-set by open pollination were positively associated with increasing CAD and aridity, respectively. Spontaneous self-pollination was not influenced by increasing CAD and aridity. Our results revealed that even though pollen traits decrease with higher CAD and aridity, pollination of T. palmadora is maintained or even increased in the most arid and disturbed areas of the park. We conclude that, in terms of pollination effectiveness, T. palmadora might be thriving under disturbances and aridity in the Caatinga dry forest.

Abstract	In mixed-ploidy populations, newly formed polyploids initially occur at low frequencies when compared to diploids. However, polyploidy may lead to morphological and phenological changes, which promote reproductive isolation and favor polyploid establishment and reproductive success. Additionally, previous studies have shown that polyploidy can confer some adaptive advantages to organisms in stressful environments. Here, we investigate variation in reproductive phenology, floral traits and reproductive success between diploid and autotetraploid trees of Libidibia ferrea (Mart. Ex Tul.) L.P. Queiroz (Leguminosae) in a mixed tropical urban population, a stressful environment. We assessed ploidy levels, flowering and fruiting phenology, flowering synchrony, floral and reproductive biology, pollination and fruit and seed set. We tested the hypothesis that autotetraploid individuals have a higher frequency of pollinators and higher fruit and seed set per inflorescence (as a proxy of reproductive success) than diploids in an urban green space. Libidibia ferrea is a good model to test our hypothesis because it is self-incompatible (i.e. relies on pollinators to set fruits). In the urban ecosystem studied, we found that diploids flowered for 6-7 months/year and autotetraploids for 3-5 months/year. Flowering synchrony was low between and within cytotypes and even though autotetraploids and diploids exhibited some overlap in flowering period, diploids flowered alone for 2-3 months. Autotetraploids had significantly more flowers per inflorescences, larger flowers and larger pollen grains (as expected for polyploids), but also a higher frequency of visits by legitimate pollinators including two exclusive ones, and higher fruit and seed set per inflorescence when compared to diploids, despite having a shorter flowering period. Our findings reveal some advantages for polyploids over their related diploids in a tropical urban green space. Also, our results highlight the need for more studies that seek to understand abiotic mechanisms affecting reproductive output of polyploids in urban ecosystems.

Abstract	Urbanization has rapidly increased in recent decades and the negative effects on biodiversity have been widely reported. Urban green areas can contribute to improving human well-being, maintaining biodiversity, and ecosystem services (e.g. pollination). Here we examine the evolution of studies on plant–pollinator interactions in urban ecosystems worldwide, reviewing also research funding and policy actions. We documented a significant increase in the scientific production on the theme in recent years, especially in the temperate region; tropical urban ecosystems are still neglected. Plant–pollinator interactions are threatened by urbanization in complex ways, depending on the studied group (plant or pollinator [generalist or specialist]) and landscape characteristics. Several research opportunities emerge from our review. Research funding and policy actions to pollination/pollinator in urban ecosystems are still scarce and concentrated in developed countries/temperate regions. To make urban green spaces contribute to the maintenance of biodiversity and the provision of ecosystem services, transdisciplinary approaches (ecological–social–economic–cultural) are needed.

Abstract	Animal pollination services provide multiple benefits to humanity as they contribute to 35% of global food production and directly account for up to 40% of the dietary nutrient supply to humanity worldwide. Population declines of vertebrate and invertebrate pollination vectors may threaten human nutrition and well-being, particularly where agriculture relies heavily on animal pollinators. We examined the relative differences in nutrient concentrations of 45 leading crops produced throughout Brazil, the world's largest tropical agricultural producer and exporter. We also estimated the overall reductions in nutrient yields under different scenarios of pollinator declines, based on annual agricultural production. Of the 45 top-ranking crops, 29 and 16 were classified as pollinator-dependent and non-dependent, respectively. Pollinator-dependent crops provided 47% of all dietary nutrients supplied in 2017, which had significantly higher concentrations of lipids, vitamin B9, and potassium, while pollinator non-dependent crops provided higher carbohydrate content. Under either a best- or worst-case pollinator declines scenario, we estimate overall nutritional losses of 7.9% and 29.5%, respectively. These losses ranged from 4% to 18% for all macronutrients, 6.8%–26.2% for all minerals, and 2.4%–31.5% for all vitamins. We emphasize the need for land-use strategies that sustain, if not increase pollinator abundance and species diversity to ensure agricultural viability and future food security.

Abstract	Chronic anthropogenic disturbances and climate change are the main threats to biodiversity, acting as potential drivers of assembly reorganization in human-modified tropical landscapes. We aimed to understand how the reproductive traits of edible fruit plant assemblages respond to chronic disturbances and aridity in the Caatinga, a dry forest in northeastern Brazil housing a human population that greatly depends on natural resources for subsistence and is threatened by increasing aridity. The study was carried out across 20 permanent plots of Caatinga, covering gradients of chronic disturbances (livestock grazing, wood extraction and non-timber product exploitation) and aridity (1051 mm to 664 mm). We registered 24 native plant species with fruits that are edible for humans, which were classified according to their flowering/fruiting pattern, floral size and reward, sexual and reproductive systems, pollination systems, and fruit types. They were also grouped into two categories of reproductive strategies (generalists and specialists). We documented that chronic disturbances and aridity pose more negative than positive effects on the reproductive traits of edible fruit plants in terms of trait richness (negative: 29% of the traits; positive: 3.2%) and abundance (negative: 19.3%; positive: 3.2%). In general, we observed that 79.2% of the studied species had at least one reproductive trait that was negatively reduced by increased chronic disturbance and/or aridity in terms of trait richness and abundance. Overall, 75% of the edible fruit species have specialized reproductive strategies that were negatively affected by chronic disturbances and/or aridity. Specifically, individual or combined effects of chronic anthropogenic disturbances or aridity negatively impacted the richness and abundance of specialized reproductive traits such as supra-annual flowering and fruiting patterns and obligatory cross-pollinated edible fruit species. Also, in terms of richness, the reproductive functional diversity of specialized reproductive strategies was negatively affected by increasing aridity. Our findings indicate that in the expected future scenarios of increased land-use and climate change, the Caatinga could face a collapse in the offer of edible fruits to local human communities by impacting the provision of this ecosystem service.

Abstract	Urbanization affects the occurrence, abundance and distribution of pollinators worldwide. Although urban green spaces support many pollinators, global estimates of urban pollinator diversity are still lacking. Here, we present a global overview of urban pollinators, characterizing the most frequently recorded species and functional groups, as well as the types of urban green spaces where these pollinators were most frequently recorded. A systematic review of the literature revealed a total of 11,560 pollinator records in urban green areas. These comprised 3148 species from 255 cities in 46 countries, with more than half of the studies (~67 %) carried out in non-tropical cities. Hymenoptera was the main pollinator group recorded, especially bees, followed by Lepidoptera and Diptera worldwide. However, birds were more commonly reported in tropical than non-tropical regions, highlighting their importance as pollinators in the tropics. The most frequently recorded species were social and generalist bees, including invasive and managed species. Hence, while some bees may be able to persist in urban areas, other groups may face challenges that need to be considered when planning urban pollinator conservation. Considering the urban habitat types where pollinators were sampled, university campuses and gardens were the most common types investigated in tropical and non-tropical regions, respectively. These results may reflect regional differences in urban landscape characteristics, as well as a research bias caused by greater investment in urban ecology research in non-tropical countries. Our review synthetizes the diversity of urban pollinators worldwide and highlights the gaps and challenges in promoting their conservation more inclusively.
