Abstract The status of wild bees has received increased interest following recent estimates of large-scale declines in their abundances across the United States. However, basic information is limited regarding the factors affecting wild bee communities in temperate coniferous forest ecosystems. To assess the early responses of bees to bark beetle disturbance, we sampled the bee community of a Douglas-fir, Pseudotsuga menziesii (Mirb.), forest in western Idaho, United States during a Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins (Coleoptera: Curculionidae), outbreak beginning in summer 2016. We resampled the area in summer 2018 following reductions in forest canopy cover resulting from mortality of dominant and codominant Douglas-fir. Overall, results from rarefaction analyses indicated significant increases in bee diversity (Shannon’s H) in 2018 compared to 2016. Results from ANOVA also showed significant increases in bee abundance and diversity in 2018 compared to 2016. Poisson regression analyses revealed percent tree mortality from Douglas-fir beetle was positively correlated with increases in total bee abundance and species richness, where community response variables displayed a cubic trend with percent tree mortality. Percent reduction in canopy cover from 2016 to 2018 was also correlated with bee species richness and diversity. These findings suggest that wild bee communities may benefit from changes in forest structure following bark beetle outbreaks.

Abstract. Purwayantie S, Suryadi UE. 2020. Plant diversity and nutrient substances of native edible plant: Case study in Suka Maju and Tamao Villages, Kapuas Hulu District, West Kalimantan, Indonesia. Biodiversitas 21: 842-852. The existence of plant diversity which is wild, indigenous and edibles, needs to be preserved. The research locations in Suka Maju and Tamao Village, Kapuas Hulu District, West Kalimantan, Indonesia were chosen based on population density. The purpose of this study was to determine the plant diversity and nutritional potential from both of regions. The study method used sampling survey and the data were analyzed descriptively. The results showed that from a total of 110 plants, the three local plant names were subjected to one species and nine species were found in both locations. So that from 98 plants consisting of 44 fruits (14 of table fruits and 30 fruits of suka-suka), 30 vegetables and mushrooms, 14 seasonings, 7 nuts, 3 cereals, and tuber. The discovery of rare genera reported from West Kalimantan, they are Hydnocarpus sp, Hodgsonia sp, and Hypoxylon spp. The highest proximate content of carbohydrate is from joluk kusuk seeds (C. lacryma jobil), fats from kepayang seeds (P. edule) and dangkuk seeds (Hydnocarpus sp), protein from sengkubak leaves (A. papuana), ash from keranji (Hypoxylon spp) and dangkuk. The highest Fe and Zn mineral content were found from sengkuang fruit (D. dao) and tepus leaves (E. foetidum), respectively. The results of this survey became an initial recommendation in the development of local wisdom for local food security.

Functional Trait Diversity

Urbanization is one of the major anthropogenic processes contributing to local habitat loss and extirpation of numerous species, including wild bees, the most widespread pollinators. Little is known about the mechanisms through which urbanization impacts wild bee communities, or the types of urban green spaces that best promote their conservation in cities. The main objective of this study was to describe and compare wild bee community diversity, structure, and dynamics in two Canadian cities, Montreal and Quebec City. A second objective was to compare functional trait diversity among three habitat types (cemeteries, community gardens and urban parks) within each city. Bees were collected using pan traps and netting on the same 46 sites, multiple times, over the active season in 2012 and 2013. A total of 32,237 specimens were identified, representing 200 species and 6 families, including two new continental records,Hylaeus communisNylander (1852) andAnthidium florentinum(Fabricius, 1775). Despite high community evenness, we found significant abundance of diverse species, including exotic ones. Spatio-temporal analysis showed higher stability in the most urbanized city (Montreal) but low nestedness of species assemblages among the three urban habitats in both cities. Our study demonstrates that cities are home to diverse communities of wild bees, but in turn affect bee community structure and dynamics. We also found that community gardens harbour high levels of functional trait diversity. Urban agriculture therefore contributes substantially to the provision of functionally diverse bee communities and possibly to urban pollination services.

Glacial Landforms

Understanding how plant community assemblage is affected by spatial and temporal patterns is crucial to understanding forest ecosystem responses to disturbance, including future climate change. In this article, we tracked how diversity and composition are distributed through space and time in a midsuccessional mixed hardwood forest in northern lower Michigan, United States. This region’s geographically and abiotically distinct glacial landforms influence both the spatial and temporal dynamics of its forest communities. Vegetation sampling plots (n = 87) were established at the University of Michigan Biological Station in 1990 and resampled in 2015. Vegetation in the overstory, sapling, and groundcover layers was censused. Abiotic variables, including elevation, pH, and soil nutrients, were measured in a subset of plots (n = 40). There were strong differences in diversity and community composition among glacial landforms, with the moraine having a 31% greater species richness in the groundcover layer compared with those of the other glacial landforms. Surprisingly, plant communities across all three vegetation layers showed little change over the 25-year period, and we found no evidence of differences in successional rates among glacial landforms. Our findings indicate that glacial landforms have a large influence on the production and maintenance of local plant diversity and community composition in this area and suggest that successional dynamics may manifest themselves over much longer time periods in these northern biomes.

AbstractWe investigated changes in a wild bee community by repeating a detailed historical study of bee biodiversity in Ontario. In 1968 and 1969 (period 1), an inventory of bee species was taken from an old field habitat in southern Ontario. We resampled the bee fauna in 2002 and 2003 (period 2), following the same methods. Bee species richness, diversity, and evenness were significantly greater in period 2, and this was observed in all functional guilds except wood-nesting, pollen specialist, and nonnative bees. In period 2, a total of 150 bee species were found (2002, 98 species; 2003, 143 species), whereas in period 1, a total of 105 species were found (1968, 98 species; 1969, 76 species). Although 90 bee species collected in period 1 were re-collected in period 2, bee community composition was remarkably different between periods, with an estimated community similarity of only 7.5%. Changes in the bee fauna, specifically the increase in the proportions of pollen specialist and wood-nesting bees, might be best explained by changes in the habitat as a result of succession over the intervening 34 years. We compare and contrast our findings of bee community change with the published literature and discuss the possible factors driving the change.
