Sensory and Cognitive Adaptations to Social Living in Insect Societies Tom Wenseleersa,1 and Jelle S
COMMENTARY COMMENTARY Sensory and cognitive adaptations to social living in insect societies Tom Wenseleersa,1 and Jelle S. van Zwedena A key question in evolutionary biology is to explain the solitarily or form small annual colonies, depending upon causes and consequences of the so-called “major their environment (9). And one species, Lasioglossum transitions in evolution,” which resulted in the pro- marginatum, is even known to form large perennial euso- gressive evolution of cells, organisms, and animal so- cial colonies of over 400 workers (9). By comparing data cieties (1–3). Several studies, for example, have now from over 30 Halictine bees with contrasting levels of aimed to determine which suite of adaptive changes sociality, Wittwer et al.

NHESP is responsible for the conservation and protection of hundreds of species that are not hunted, fished, trapped, or commercially harvested in the state. The Program's highest priority is protecting the 176 species of vertebrate and invertebrate animals and 259 species of native plants that are officially listed as Endangered, Threatened or of Special Concern in Massachusetts. Endangered species conservation in Massachusetts depends on you! A major source of funding for the protection of rare and endangered species comes from voluntary donations on state income tax forms.

ENH1308 Biology and Management of Spanish Needles (Bidens spp.) in Ornamental Crop Production1 Yuvraj Khamare, Chris Marble, Shawn Steed, and Nathan Boyd2 Introduction Family All eight species of Bidens in Florida are commonly referred Asteraceae (Compositae) to as Spanish needles or beggar-ticks (Wunderlin, 2019). This document focuses on Bidens alba and B. pilosa, which Other Common Names are common weeds in container nurseries and landscapes Blackjack, beggar-ticks, cobbler’s pegs, farmer’s friends in Florida. Both of these species are very similar in appear- ance and biology and are capable of interbreeding (Norton, Life Span 1991). Due to the similarity between these species, they are Both species are annual or short-lived perennials sometimes recognized as one in the literature (Wunderlin, 2019). Their differences are distinctive, however, as B. pilosa Habitat flowers usually do not have petals while B. alba usually does. B. alba is also more widely distributed throughout Spanish needles occur in many different habitats, ranging Florida than B. pilosa. For the purposes of this document, from moist fertile soil to dry and infertile soil and sandy we refer to both species as “Spanish needles.” This EDIS soils.

It is a 7.5 acre conservation area, owned by the City of Key West. The KWBG requested that The Institute for Regional Conservation (IRC) conduct a floristic evaluation of its natural areas and grounds and to provide recommendations. Study Design On August 9-10, 2005 an inventory of all vascular plants was conducted at the KWBG. All areas of the KWBG were visited, including the newly acquired property to the south. Special attention was paid toward the remnant natural habitats. A preliminary plant list was established. Plant taxonomy generally follows Wunderlin (1998) and Bailey et al. (1976). Results Five distinct habitats were recorded for the KWBG. Two of which are human altered and are artificial being classified as developed upland and modified wetland. In addition, three natural habitats are found at the KWBG. They are coastal berm (here termed buttonwood hammock), rockland hammock, and tidal swamp habitats. Developed and Modified Habitats Garden and Developed Upland Areas The developed upland portions include the maintained garden areas as well as the cleared parking areas, building edges, and paths. -

Insect pheromones are usually substances from multiple sources, store them in specialized tibial synthesized de novo or modified from dietary precursors (Roelofs, pouches and later expose them at display sites, presumably as 1995).

The Evolution of Sexual Signaling Is Linked to Odorant Receptor Tuning in Perfume-Collecting Orchid Bees
ARTICLE https://doi.org/10.1038/s41467-019-14162-6 OPEN The evolution of sexual signaling is linked to odorant receptor tuning in perfume-collecting orchid bees Philipp Brand 1,6*, Ismael A. Hinojosa-Díaz2, Ricardo Ayala3, Michael Daigle1, Carmen L. Yurrita Obiols4, Thomas Eltz5 & Santiago R. Ramírez 1* 1234567890():,; Sexual signaling is an important reproductive barrier known to evolve early during the for- mation of new species, but the genetic mechanisms that facilitate the divergence of sexual signals remain elusive. Here we isolate a gene linked to the rapid evolution of a signaling trait in a pair of nascent neotropical orchid bee lineages, Euglossa dilemma and E. viridissima. Male orchid bees acquire chemical compounds from their environment to concoct species-specific perfumes to later expose during courtship. We find that the two lineages acquire chemically distinct perfumes and are reproductively isolated despite low levels of genome-wide differ- entiation. Remarkably, variation in perfume chemistry coincides with rapid divergence in few odorant receptor (OR) genes. Using functional assays, we demonstrate that the derived variant of Or41 in E. dilemma is specific towards its species-specific major perfume compound, whereas the ancestral variant in E. viridissima is broadly tuned to multiple odorants. Our results show that OR evolution likely played a role in the divergence of sexual communication in natural populations. 1 Department of Evolution and Ecology, Center for Population Biology, University of California, 1 Shields Avenue, 95616 Davis, California, USA. 2 Departamento de Zoología, Instituto de Biología, Universidad Nacional Autónoma de México, Tercer Circuito s/n Ciudad Universitaria Delegación Coyoacán, Apartado Postal 70-153, Ciudad de México 04510, Mexico. -

Pollen samples were obtained from nests collected in the rainy season of three consecutive years (2006–2008). Solanum sp. (Solanaceae), Physalis sp. (Solanaceae), Ocimum sp., Ocimum micranthum (both Lamiaceae), and Senna sp. (Fabaceae) were the dominant taxa, accounting for 88 % of pollen volume across species. Other important pollen taxa were Croton spp. (Euphorbiaceae), Ipomoea sp. (Convolvulaceae), Solanum torvum, Vigna sp. (Fabaceae), Sida sp. (Malvaceae), and Randia aculeata (Rubiaceae). The predominantly buzz- pollinated family Solanaceae alone represented more than 77 % of total pollen volume. Multivariate analysis revealed significant effects of year but not of bee species on nest pollen composition. We conclude that pollen resources overlap substantially among these sibling species, with resource partitioning apparently absent or confined to periods of severe pollen scarcity. pollen provisions / resource partitioning / floral resource competition / acetolysis / pollen analysis 1. -
