Bumblebees' Bombus Impatiens
Bumblebees’ Bombus impatiens (Cresson) Learning: An Ecological Context by Hamida B. Mirwan A Thesis Presented to The University of Guelph In partial fulfillment of requirements for the degree of Doctor of Philosophy in School of Environmental Biology Guelph, Ontario, Canada © Hamida B. Mirwan, August, 2014 ABSTRACT BUMBLEBEES’ BOMBUS IMPATIENS (CRESSON) LEARNING: AN ECOLOGICAL CONTEXT Hamida B. Mirwan Co-Advisors: University of Guelph, 2014 Professors Peter G. Kevan & Jonathan Newman The capacities of the bumblebee, Bombus impatiens (Cresson), for learning and cognition were investigated by conditioning with increasingly complex series of single or multiple tasks to obtain the reinforcer (50% sucrose solution). Through operant conditioning, bumblebees could displace variously sized combinations of caps, rotate discs through various arcs (to 180°), and associate rotation direction with colour (white vs. yellow). They overcame various tasks through experience, presumably by shaping and scaffold learning. They showed incremental learning, if they had progressed through a series of easier tasks, single caps with increasing displacement complexity (to left, right, or up) or of balls with increasing masses, but could not complete the most difficult task de novo. They learned to discriminate the number of objects in artificial flower patches with one to three nectary flowers presented simultaneously in three compartments, and include chain responses with three other tasks: sliding doors, lifting caps, and rotating discs presented in fixed order. Pattern recognition and counting are parts of the foraging strategies of bumblebees. Multiple turn mazes, with several dead ends and minimal visual cues, were used to test the abilities of bumblebees to navigate by walking and remember routes after several days. -
Malpighiaceae De Colombia: Patrones De Distribución, Riqueza, Endemismo Y Diversidad Filogenética

C., Colombia; [email protected] (autor corresponsal). Abstract. Giraldo-Cañas, D. 2021. Malpighiaceae from Colombia: Patterns of distribution, richness, endemism, and phylogenetic diversity. Darwiniana, nueva serie 9(1): 39-54. Malpighiaceae constitutes a family of 77 genera and ca. 1300 species, distributed in tropical and subtropical regions of both hemispheres. They are mainly diversified in the American continent and distributed in a wide range of habitats and altitudinal gradients. For this reason, this family can be a model plant group to ecological and biogeographical analyses, as well as evolutive studies. In this context, an analysis of distribution, richness, endemism and phylogenetic diversity of Malpighiaceae in natural regions and their altitudinal gradients was undertaken. Malpighiaceae are represented in Colombia by 34 genera and 246 species (19.1% of endemism). Thus, Colombia and Brazil (44 genera, 584 species, 61% of endemism) are the two richest countries on species of this family. The highest species richness and endemism in Colombia is found in the lowlands (0-500 m a.s.l.: 212 species, 28 endemics); only ten species are distributed on highlands (2500-3200 m a.s.l.). Of the Malpighiaceae species in Colombia, Heteropterys leona and Stigmaphyllon bannisterioides have a disjunct amphi-Atlantic distribution, and six other species show intra-American disjunctions. -

The Conservation Management and Ecology of Northeastern North
THE CONSERVATION MANAGEMENT AND ECOLOGY OF NORTHEASTERN NORTH AMERICAN BUMBLE BEES AMANDA LICZNER A DISSERTATION SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY GRADUATE PROGRAM IN BIOLOGY YORK UNIVERSITY TORONTO, ONTARIO September 2020 © Amanda Liczner, 2020 ii Abstract Bumble bees (Bombus spp.; Apidae) are among the pollinators most in decline globally with a main cause being habitat loss. Habitat requirements for bumble bees are poorly understood presenting a research gap. The purpose of my dissertation is to characterize the habitat of bumble bees at different spatial scales using: a systematic literature review of bumble bee nesting and overwintering habitat globally (Chapter 1); surveys of local and landcover variables for two at-risk bumble bee species (Bombus terricola, and B. pensylvanicus) in southern Ontario (Chapter 2); identification of conservation priority areas for bumble bee species in Canada (Chapter 3); and an analysis of the methodology for locating bumble bee nests using detection dogs (Chapter 4). The main findings were current literature on bumble bee nesting and overwintering habitat is limited and biased towards the United Kingdom and agricultural habitats (Ch.1). Bumble bees overwinter underground, often on shaded banks or near trees. Nests were mostly underground and found in many landscapes (Ch.1). B. terricola and B. pensylvanicus have distinct habitat characteristics (Ch.2). Landscape predictors explained more variation in the species data than local or floral resources (Ch.2). Among local variables, floral resources were consistently important throughout the season (Ch.2). Most bumble bee conservation priority areas are in western Canada, southern Ontario, southern Quebec and across the Maritimes and are most often located within woody savannas (Ch.3). -

Epilist 1.0: a Global Checklist of Vascular Epiphytes
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 EpiList 1.0: a global checklist of vascular epiphytes Zotz, Gerhard ; Weigelt, Patrick ; Kessler, Michael ; Kreft, Holger ; Taylor, Amanda Abstract: Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vas- cular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes evenwrong. -
Nest Construction and Architecture of the Amazonian Bumble Bee (Hymenoptera: Apidae)

CAMERONb* a Department of Biology, University of Victoria, PO Box 1700 STN CSC Victoria, BC, V8W 2Y2 Canada b Department of Entomology, University of Illinois, Urbana-Champaign, 320 Morrill Hall, 505 S. Goodwin Ave., Urbana, IL 61801, USA (Received 8 February 2002; revised and accepted 1 November 2002) Abstract – The Amazonian bumble bee, Bombus transversalis, is mostly restricted to tropical rain forest of the Amazon Basin. Little is known of its biology, in part because its surface nests are cryptic and hard to find. Here we examine nest site characteristics, nest architecture and construction behavior from 16 colonies observed in different regions of Amazonia. We quantify structural features of the nest habitat and external and internal characteristics of the nests. We ascertain that nests are constructed on terra firme, on the surface of the ground and incorporate elements of growing vegetation as physical support. Nests consist of a thatched canopy of tightly woven leaves and rootlets, beneath which lies the brood and food storage pots. To build the nest, workers cut and transport leaves from the surrounding forest floor. Nests are dry inside, despite torrential rainfall and external relative humidity levels near 100%. Nests may be reused although a colony appears to persist for only one season. corbiculate -
