“…The data on forage plants found around the cultivation areas was the basic data used for the process of identifying the potential forage of stingless The species of Bromeliaceae with short corollas of flowers were usually visited by bees (Freitas et al 2020). Previous studies showed that this family was one of the sources of pollen for the stingless bees on clypearis in all land types.…”

The success of stingless beekeeping was supported by site suitability and the availability of floral sources. Bee feed is an important requirement for the sustainability of stingless beekeeping because it determines the qualities and quantities of bee products. The study aimed to examine the level of feed preference for stingless bees. The research location was divided into three types, i.e., agroecosystems, forests, and settlements. Acetolysis of the pollen where came from the hive was used to examine the foraging preferences of stingless bees. The results of the study were four species of stingless bee were identified, i.e., Tetragonula fuscobalteata, Tetragonula laeviceps, Tetragonula clypearis, and Heterotrigona erythrogastra. Based on the results of the data analysis, T. fuscobalteata was mostly cultivated in the settlement areas, T. laeviceps and T. clypearis were mostly found at the sites that were close to the agroecosystems, while H. erythrogastra was cultivated near the forest areas. The pollen that be favorite feed plants of Tetragonula was Bromeliaceae and Cyperaceae, while for H. erythrogastra, Rubiaceae was the preference of forage plants. However, the PCA showed that the preference of forage plants for the beekeeping of stingless bees was influenced by the availability of feed sources around their hives.

“…Plant rarity is related to evolutionary and ecological processes, which are influenced by life-history features, interactions with other species and environmental conditions, and anthropogenic effects [ 1 – 4 ]. Reproduction is an essential and relatively fragile stage in the life cycle of plants, and it is key to evolution [ 5 ].…”

Background Plants in cliff habitats may evolve specific reproductive strategies to cope with harsh environments, and unraveling these reproductive characteristics can improve our understanding of survival strategies and lithophyte evolution. This understanding is especially important for efforts to protect rare and endemic plants. Here, we investigated the reproductive biology of Lonicera oblata, an endangered lithophytic shrub that is scattered in highly fragmented and isolated cliff habitats of the Taihang and Yan mountains in North China. Results Flowers of L. oblata are herkogamous and protandrous, characteristics that can prevent autogamy at the single-flower level, and insects are necessary for pollination. The outcrossing index, pollen/ovule ratio, and the results of hand pollination were measured and all revealed a mixed mating system for L. oblata, that combines cross-fertilization and partial self-fertilization. The floral traits of L. oblata of zygomorphic and brightly yellowish corolla, heavy fragrance, and rich nectar, suggest an entomophilous pollination system. Sweat bees were observed as the most effective pollinators but their visiting frequencies were not high. Pollen limitation may limit the reproductive success of L. oblata. Conclusions We determined the reproductive characteristics of L. oblata, a critically endangered species endemic to cliffs in North China, providing insight into its endangerment and suggesting conservation strategies. L. oblata has highly pollinator-dependent self-fertilization as part of a mixed mating system. Floral features such as low-flowering synchrony, asynchronous anthers dehiscence, and high duration of stigma receptivity, improve pollination efficiency in the case of low pollinator service. Our work provides reference information to understand the survival strategies and conservation of L. oblata and other lithophytes.

Background and aims – The Bromeliaceae family has great importance in the maintenance of neotropical communities. In the Brazilian Atlantic Forest, bromeliads are among the major groups responsible for maintaining the local flora and fauna and participate in important ecological interactions with insects, anurans, and hummingbirds. This work reports on aspects of the reproductive biology and the interactions between two endemic bromeliad species from the Atlantic Forest (Aechmea bruggeri and Quesnelia indecora) and their floral visitors to assess the impact of these relationships on the reproductive success and conservation of these plants.Material and methods – Reproductive phenology, floral biology, pollination experiments, and the reproductive success of both species were investigated. To determine the floral visitors, we made direct observations on flowers and collected floral visitors that could not be identified in the field.Key results – Aechmea bruggeri and Quesnelia indecora presented the individual and population flowering phenological pattern classified as annual with intermediate duration. The species are partially and totally self-incompatible, respectively. Both species presented a varied visitation guild, and although Q. indecora presented flowers with ornitofilous characteristics, no hummingbirds were recorded for this species. The hummingbird Thalurania glaucopis was the main visitor for Aechmea bruggeri and the bee Trigona cf. braueri was the main visitor for Quesnelia indecora. Nectar thieving by lepidopterans was observed for both species. Pollen robbing by beetles and nectar robbing by bees were registered for Aechmea bruggeri and Quesnelia indecora, respectively. Fruit and seed set of both species were highly affected by herbivory, which may negatively affect their reproductive success.Conclusion – Our work highlights the important role of bromeliads in neotropical communities, showing how floral visitors and plants interact by participating in maintaining biological diversity in the studied forest remnant.
