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. -
A Locality for Maxillaria Aureoglobula Christenson in Colombia
ISSN 2325-4785 New World Orchidaceae – Nomenclatural Notes Nomenclatural Note – Issue No. 21 June 5, 2016 www.newworldorchidaceae.com A Locality for Maxillaria aureoglobula Christenson in Colombia. Ruben P. Sauleda 22585 SW 187 Ave. Miami, FL. 33170 ABSTRACT Maxillaria aureoglobula Christenson was described from a cultivated plant without locality. A locality is given for this species. The transfer of M. aureoglobula to an “expanded” version of the genus Mormolyca Fenzl based on molecular analysis is questioned. Calima Lake is the largest artificial lake in Colombia with an area of 70 km². It is located in the municipality of Darién in the Valle del Cauca Department. The lake is part of a hydroelectric project for generating power for the department. Along the road that leads from the lake to the hydroelectric plant, at an elevation of 1480 m, a small flowered Maxillaria Ruiz & Pavon in the section Rufescens Christenson (Proc. 16 World Orchid Conf. 285-286. 2002) was discovered. The plant was Maxillaria aureoglobula Christenson (Orchids, Mag. Amer. Orchid. Soc. 71(2): 125-126. 2002). The species was described from a cultivated plant. No specific locality was given, only Colombia. This paper establishes a locality for Colombia. Maxillaria aureoglobula is also recorded from Venezuela by a color photograph (opposite page 161) in Dunsterville & Garay (1961) as Maxillaria rufescens Lindl. That plant was said to come from the cloud forests near Maracay. Dunsterville & Garay comment “This Maxillaria belongs to a species that is extremely variable both as to the size and appearance of its leaves as well as to the size and appearance of its flowers.” Subsequently several new species previously considered M. -

Orquideas Brasileiras E Abelhas
ORQUÍDEAS BRASILEIRAS E ABELHAS Texto e fotos: Rodrigo B. Singer Agradecimentos a Rosana Farias-Singer ORQUÍDEAS: DIVERSIDADE E MORFOLOGIA GERAL As orquídeas (família Orchidaceae) constituem um dos maiores (ca. 19.500 spp.) e mais diversos agrupamentos de angiospermas. Hoje são aceitas cinco subfamílias dentro de Orchidaceae (Cameron et al. 1999, Judd et al. 1999) (Figura 1). Como um todo, a família Orchidaceae é notável pela sua diversificada morfologia floral e vegetativa. No entanto, o estereótipo (flores grandes e muito ornamentais, presença de “pseudobulbos”, etc.) que a maioria das pessoas têm em relação à Orchidaceae diz respeito apenas a caracteres morfológicos próprios de uma das cinco subfamílias (Epidendroideae). No entanto, há caracteres comuns a todas as orquídeas: o ovário é ínfero, sincárpico (carpelos fusionados). O perianto consta de dois verticilos trímeros (3 sépalas e 3 pétalas) (Figura 2), sendo que a pétala mediana com freqüência é maior e apresenta glândulas (nectários, glândulas de óleo, osmóforos, etc.) ou ornamentações (calos) com funções relacionadas ao processo de polinização. Por ser morfologicamente diferenciada, a pétala mediana é denominada de “labelo” (lábio, em latim). A posição original do labelo (para cima) é modificada durante a ontogênese da flor. O pedicelo floral, o ovário ou ambos sofrem uma torção (ressupinação) que faz com que o labelo seja apresentado para baixo por ocasião da abertura da flor. Assim, o labelo pode atuar como plataforma de pouso ou guia mecânica para os polinizadores. Androceu e gineceu encontram-se fusionados em maior ou menor grau, formando uma estrutura única denominada coluna (Figuras 2 e 3). O número de anteras férteis em geral é muito reduzido (normalmente uma, mas raramente duas ou – muito mais raramente - três) (Figura 1). -

REGULAR PAPER COMPARATIVE ULTRASTRUCTURE OF THE MANDIBULAR GLAND IN Scaptotrigona postica (HYMENOPTERA, APIDAE, MELIPONINI) WORKERS AND MALES Luciana Fioretti Gracioli-Vitti1 and Fábio Camargo Abdalla2 1Department of Biology, Institute of Biosciences, Paulista State University (UNESP), Rio Claro and 2Department of Biology, Federal University of São Carlos (UFSCar), Sorocaba, SP, Brazil. ABSTRACT Differences in the ultrastructure and function of the mandibular glands in developing workers and mature males of the meliponine stingless bee Scaptotrigona postica suggest that there are age-dependent variations in the contents of the secretion and glandular functions. In this work, we used transmission (TEM) and scanning (SEM) electron microscopy to examine the mandibular glands of S. postica workers of different ages and compared them with those of mature males. The gland anatomy did not vary between workers and males. However, the ultrastructure of the gland cells changed according to the worker’s age, task, and sex. The mandibular gland cells in workers and males had a well developed smooth endoplasmic reticulum and pleomorphic mitochondria, indicating that the cells were involved in lipid synthesis. However, the secretion varied in morphology and electrondensity between workers and males, which suggested differences in its contents and, possibly, in glandular functions. Key words: Labor division, morphology, secretion, scanning electron microscopy, stingless bee, transmission electron microscopy INTRODUCTION reception and dehydration (21-45 days old), colony In eusocial bees, tasks are allocated to individuals defense (31-40 days old) and, finally, foraging (26- according to their capacity, which depends on their 60 days old) [29].

Entre ellos, las abejas constituyen un eslabón esencial en la polinización de angiospermas que durante millones de años desarrollaron estrategias cada vez más específicas para atraerlas. De esta forma se establece una relación muy fuerte entre am- bos, planta-polinizador, y cuanto mayor es la especialización, tal como sucede en un gran número de especies de orquídeas y cactáceas entre otros grupos, ésta se torna más vulnerable ante cambios ambientales naturales o producidos por el hombre. De esta forma, el estudio de este tipo de interacciones resulta cada vez más importante en vista del incremento de áreas perturbadas o modificadas de manera antrópica en las cuales la fauna y flora queda expuesta a adaptarse a las nuevas condiciones o desaparecer. -
