The Brazilian state of Piauí is one of the largest producers of organic honey in the country. Although the product is made from nectar collected from natural vegetation, including several species endemic to the Caatinga, knowledge of the beekeeping potential of semiarid vegetation remains scarce, particularly in Piauí. As such, the present study aimed to map the flora of honey-producing areas of the Alto Médio microregion in Piauí. A survey was conducted of apiaries in the region and bee production in four beekeeping communities, using data provided by the Simplício Mendes Microregion Beekeeping Cooperative (COMAPI). Geographic coordinates were used to generate a map to analyze vegetation in the region and excursions were carried out in previously defined areas to survey plants visited by honeybees. The beekeeping communities in areas with greater floral density had the highest honey production. Forty plant species were collected, with the most representative family being Fabaceae, followed by Euphorbiaceae and Anacardiaceae. Most of the plants surveyed were visited by bees with the sole purpose of collecting nectar and were flowering in months with the highest honey production. Thus, creating a flowering calendar could help beekeepers make better use of the local flora.

The Impact

Land-use changes have huge impacts on natural vegetation, especially megaprojects, as the vegetation layer is destroyed in the course of construction works affecting the plant community composition and functionality. This large-scale disturbance might be a gateway for the establishment of invasive plant species, which can outcompete the natural flora. In contrast, species occurring in the area before the construction are not able to re-establish. In this study, we analyzed the impact of a pipeline construction on a wetland nature reserve located in northern Egypt. Therefore, we analyzed the plant species occurrence and abundance and measured each plant species’ traits before the construction in 2017 as well as on multiple occasions up to 2 years after the construction had finished on altogether five sampling events. We found that the construction activity led to the establishment of an invasive species which previously did not occur in the area, namely, Imperata cylindrica, whereas five species (Ipomoea carnea, Pluchea dioscoridis, Polygonum equisetiforme, Tamarix nilotica, and Typha domingensis) could not re-establish after the disturbance. The functionality of ecosystems assessed via the analysis of plant functional traits (plant height, specific leaf area, and leaf dry matter content) changed within species over all sampling events and within the community showing a tendency to approximate pre-construction values. Functional dispersion and Rao’s quadratic diversity were higher after the megaproject than before. These findings are important to capture possible re-establishment and recovery of natural vegetation after construction and raise awareness to the impact of megaprojects, especially in areas which are high priority for conservation.

AbstractThe conversion of natural systems into farms and agroecosystems is the main cause of biodiversity loss. In human-dominated landscapes, understanding the interactions between agroforestry systems and adjacent natural vegetation is fundamental to developing sustainable agricultural systems. Species can move between these two systems with natural systems providing the regional pool of species that shape the agricultural values and conservation value of the agroforestry systems. We investigated the influence of neighboring natural habitats on traditional agroforestry systems in the buffer zone of Pendjari Biosphere Reserve in Benin to understand the contribution of regional processes on the quality of agroforestry systems. We expected that agroforestry parklands adjacent to natural vegetation with high species diversity will also have higher plant species diversity. We found no similarity in plant species composition between agroforestry systems and adjacent natural habitats. A small proportion of species in adjacent natural habitats were found in agroforestry systems. The proportion of shared species was not significantly influenced by plant diversity in adjacent natural habitats or the distance from the agroforestry systems to the natural adjacent habitat. However, plant diversity in agroforestry systems was strongly associated with site ethnobotanical values indicating that farmers act as a supplemental but severe environmental filter of the regional species pool. Our study suggests that promoting the plantation of plants with high ethnobotanical use-value is a potentially viable strategy for sustainable agriculture and ecological restoration in Biosphere reserves.

Floral Syndrome

Pollinator preference has been demonstrated to depend on floral morphology in some plant groups. We tested bee preference for Amelanchier nantucketensis, which has pollen-bearing petals or andropetals, over Amelanchier humilis with its normal petals when these flower together at two Maine sites. In an array experiment with equal floral display for Amelanchier nantucketensis and Amelanchier humilis, almost twice as many bees approached the latter first. Bees responded to some aspect of the larger flowers of Amelanchier humilis when number of inflorescences and height above the ground were similar. We captured 539 bees in 43 species individually on flowers, in malaise traps, and in sweeps; most were common, widely distributed solitary and eusocial bees. Bee species diversity differed slightly between plant species, and guilds differed; 11 bee species were unique to Amelanchier nantucketensis, including 39 individuals of Andrena milwaukiensis, and three species were unique to Amelanchier humilis. For 29 bee species shared by both plant species, abundance on Amelanchier nantucketensis was greater than on Amelanchier humilis for 62%, less for 14%, and the same for 24%. Bees might be attracted to Amelanchier nantucketensis less by andropetaly than by proximity of flowers to the ground, floral density, or unidentified features. Key words: Amelanchier, bees, foraging, morphology, Maine, species diversity.

Our research took place on karstic area in Aggtelek National Park in Hungary. The heavy metal content of soils with three different texture and in the plants of the natural vegetation (oak- , hornbeam-, corn leaves, greenery) were studied. Ratio of total (acid soluble) metal contents and bioavailable metal contents of the soils were calculated. Based on these results we determined the mobility of the metals in different soils. Used the metal contents of the soils and the vegetation we set up a sequence of the mobility of the metals between the soil and the most frequent plant species.

The aim of this study is to describe interactions between hummingbirds and ornithophilous species at Serra da Bodoquena in midwest Brazil, with focus on flowering phenology and pollination of these plant species. In two habitats, gallery forest and semi-deciduous forest, data on flowering phenology of ornithophilous species were collected monthly over 14 months. In addition, data on morphology and floral biology, as well as visitor frequency and hummingbird behavior, were recorded. The studied community contained eight ornithophilous plant species and six hummingbird species. The ornithophilous species flowered throughout the year, and the greatest abundance of flowers was at the end of the rainy season and the beginning of the dry one. The herit huingbird Phaethornis pretrei and feales of Thalurania furcata, were the most similar in floral resource use. Acanthaceae is the most representative family of ornithophilous plant species in Serra da Bodoquena and, thus, represents the main food source for hummingbirds. Ruellia angustiflora is especially important because it flowers continuously throughout the year and is a significant food resource for P. pretrei, which is the main visitor for this plant guild.

AbstractThe plants foraged by bees for honey production vary from place to place in the diverse flora of India. This paper reports a palynological study of honey from eight sites of agriculture and urbanisation in the Gangetic Plain of Uttar Pradesh (UP), and presents data from similar studies done in India. Pollen grains of 55 species were recorded in the honey from south-western, central and eastern parts of Uttar Pradesh, whereAgeratum conyzoides, a noxious invasive weed, is a very dominant plant taxon. The second plant community used for foraging by honeybees consists ofSyzygium cumini,Feronia limonia,Eucalyptus globulus,Prosopis spicigera,Prosopis juliflora,Brassica campestris,Pimpinella tomentosa,Xanthium strumarium, andZiziphussp. The third plant community foraged by honeybees includes diverse plant species such asCapparissp.,Ficussp.,Murraya koenigii,Aegle marmelos, andTinospora cordifolia, as well as Caryophyllaceae and nectarless families. The last group of plants foraged by honeybees comprises ca 37 species sparsely present in the vicinity. If honeybees have access to their preferred plant species they rarely visit non-preferred species, but in the urban and rural agricultural areas where the vegetation is sparse they are forced to forage several other plants including invasive species. The quality and character of honey, whether multifloral, monofloral, or bifloral, largely indicates the changing pattern of vegetation in a particular area, and can furnish decadal to century-scale information about the vegetational changes induced by climate or anthropopression. Palynological data also shed light on medicinally important or allergenic pollen protein present in honey (valuable information for consumers) and the details about plant taxa foraged by honeybees can be used for branding and marketing particular types of honey.

In Parbat district, tribal communities rear livestock mostly cattle, buffalo, goats, sheep etc. Most of the time animal diseases are treated by the uses of local herbal medicines extracted from the plants. All together 21 plant species belonging to 19 families are being identified having used to treat different veterinary diseases like; injury, poisoning, foot and mouth, wounds, stomach disorder, antiworms and bone facture of animals. These ethnoveterinary plants species are normally collected from nearby forest or natural vegetation. Some of them like, Acorus calamus, Cuscuta reflexa, Schima wallichii, Fraxinus floribunda etc are even domesticated by them in nearby cropland therefore such plants are readily available at any time.

Using Data

When species within guilds perform similar ecological roles, functional redundancy can buffer ecosystems against species loss. Using data on the frequency of interactions between fish and fruit, we assessed whether co-occurring frugivores provide redundant seed dispersal services in three species-rich Neotropical wetlands. Our study revealed that frugivorous fishes have generalized diets; however, large-bodied fishes had greater seed dispersal breadth than small species, in some cases, providing seed dispersal services not achieved by smaller fish species. As overfishing disproportionately affects big fishes, the extirpation of these species could cause larger secondary extinctions of plant species than the loss of small specialist frugivores. To evaluate the consequences of frugivore specialization for network stability, we extracted data from 39 published seed dispersal networks of frugivorous birds, mammals and fish (our networks) across ecosystems. Our analysis of interaction frequencies revealed low frugivore specialization and lower nestedness than analyses based on binary data (presence–absence of interactions). In that case, ecosystems may be resilient to loss of any given frugivore. However, robustness to frugivore extinction declines with specialization, such that networks composed primarily of specialist frugivores are highly susceptible to the loss of generalists. In contrast with analyses of binary data, recently developed algorithms capable of modelling interaction strengths provide opportunities to enhance our understanding of complex ecological networks by accounting for heterogeneity of frugivore–fruit interactions.
