“…In Colombia, the highest plant diversity and most agricultural crops are in the Andean region (Gonzalez & Engel, 2004 ; Rangel‐Ch, 2015 ), and bumble bees are among the few bee species that are present year‐round due to their perennial nests with oscillating monogyny and polygyny (one or multiple active queens) colony cycles (Gonzalez et al, 2004 ). In addition, bumble bees visit a wide range of plants (Pinilla‐Gallego & Nates‐Parra, 2015 ; Riaño‐Jiménez et al, 2020 ) and can fly at low temperatures, when other bees are unable to do so, because of their large body and thermoregulation capabilities (Bishop & Armbruster, 1999 ; Heinrich, 1979 ). Unfortunately, tropical bumble bees are expected to be more vulnerable to climate change than those from other latitudes, as tropical organisms appear to be living close to their maximum tolerable temperature and may have limited acclimation capacities (Deutsch et al, 2008 ; Kingsolver et al, 2013 ).…”

Bumble bees are key pollinators with some species reared in captivity at a commercial scale, but with significant evidence of population declines and with alarming predictions of substantial impacts under climate change scenarios. While studies on the thermal biology of temperate bumble bees are still limited, they are entirely absent from the tropics where the effects of climate change are expected to be greater. Herein, we test whether bees' thermal tolerance decreases with elevation and whether the stable optimal conditions used in laboratory‐reared colonies reduces their thermal tolerance. We assessed changes in the lower (CT Min ) and upper (CT Max ) critical thermal limits of four species at two elevations (2600 and 3600 m) in the Colombian Andes, examined the effect of body size, and evaluated the thermal tolerance of wild‐caught and laboratory‐reared individuals of Bombus pauloensis . We also compiled information on bumble bees' thermal limits and assessed potential predictors for broadscale patterns of variation. We found that CT Min decreased with increasing elevation, while CT Max was similar between elevations. CT Max was slightly higher (0.84°C) in laboratory‐reared than in wild‐caught bees while CT Min was similar, and CT Min decreased with increasing body size while CT Max did not. Latitude is a good predictor for CT Min while annual mean temperature, maximum and minimum temperatures of the warmest and coldest months are good predictors for both CT Min and CT Max . The stronger response in CT Min with increasing elevation, and similar CT Max , supports Brett's heat‐invariant hypothesis, which has been documented in other taxa. Andean bumble bees appear to be about as heat tolerant as those from temperate areas, suggesting that other aspects besides temperature (e.g., water balance) might be more determinant environmental factors for these species. Laboratory‐reared colonies are adequate surrogates for addressing questions on thermal tolerance and global warming impacts.

“…En Colombia se encuentra comúnmente entre 2100 y 2650 m s. n. m., en zonas de moderada a altamente intervenidas (Nates-Parra et al 2006). Es la especie neotropical más estudiada, por lo que se conoce bastante su biología y ecología; son pocket makers y es la única especie en Latinoamérica que ha sido domesticada para polinizar cultivos (Sakagami et al 1967;Matos and Garófalo 1995;Cameron and Jost 1998;González et al 2004;Padilla et al 2017;Riaño-Jiménez et al 2020). Por su parte, B. hortulanus se extiende desde el norte de Colombia hasta el oriente de Ecuador, entre 760 y 3660 m s. n. m. (Abrahamovich and Díaz 2002;Abrahamovich et al 2004).…”

“…Si comparamos lo que observamos hoy con lo reportado en trabajos antiguos (Osorno and Osorno 1938), es claro que las especies de abejorros aquí estudiadas, que eran habitantes comunes de la ciudad de Bogotá (e.g., B. rubicundus y B. hortulanus) han restringido mucho su rango y se han localizado en zonas mejor conservadas. El análisis del polen corporal a partir de técnicas palinológicas ha sido particularmente útil en estudios ecológicos en diferentes comunidades de abejas, ya que ofrece información amplia y detallada sobre los recursos florales usados como alimento y facilita el desarrollo de planes de manejo de la flora (Alarcón 2010;Rech and Absy 2011;Morandin and Kremen 2013;Jones 2014;Ballantyne et al 2017;Egerer et al 2020;Riaño-Jiménez et al 2020). Sin embargo, una de las limitantes más importantes en los estudios eco-palinológicos es la falta de catálogos polínicos que faciliten la identificación del polen presente en el cuerpo de los polinizadores, por lo que generalmente es necesario hacer un catálogo polínico de las plantas que se encuentren florecidas durante los estudios, exigiendo tiempo y dinero (Jones 2014).…”

“…De acuerdo con nuestras observaciones, B. pauloensis no superó los 2700 m s. n. m., encontrándose en zonas muy transformadas de la Cordillera Oriental de los Andes colombianos y asociada a plantas exóticas. La capacidad adaptativa de B. pauloensis tanto a ambientes altamente perturbados como al uso amplio de recursos florales exóticos fue descrita en Colombia y en otras regiones (Abrahamovich et al 2001;Telleira 1998;Cavigliasso et al 2019;Riaño-Jiménez et al 2020) Ecología Austral 32:567-580 C�� ₅₇₇ moderada, utilizó principalmente recursos polínicos nativos, diferentes a los utilizados por B. pauloensis cuando se solaparon. Por otro lado, B. rubicundus se encontró en zonas poco intervenidas y utilizó recursos polínicos similares a los que usó B. hortulanus.…”

R��.En América del Sur se reportan más de 20 especies de abejorros, nueve de ellas en la Cordillera Oriental de los Andes colombianos. Se las conoce como polinizadores importantes, pero su distribución fue disminuyendo debido al creciente cambio en el uso del suelo; esto ha causado el empobrecimiento de los ecosistemas andinos. Identificar y proteger los recursos florales que usan las abejas silvestres resulta clave en el manejo de áreas silvestres para mitigar el impacto de las actividades humanas en áreas muy intervenidas (e.g., ciudades o cultivos). El análisis de polen es una herramienta clave para conservar los recursos florales que utilizan las abejas, pero depende de contar con catálogos polínicos que permitan identificaciones taxonómicas adecuadas. El objetivo de este estudio fue desarrollar un catálogo de polen de las plantas que utilizan tres de los abejorros andinos más comunes, Bombus rubicundus, B. hortulanus y B. pauloensis. Los muestreos se realizaron en seis localidades de la sabana de Bogotá, cubriendo un gradiente de altitud entre 2600 y 3500 m s. n. m. Se prepararon muestras florales de todas las localidades mediante acetólisis, y luego se las analizó. Se digitalizó un catálogo de referencia a partir del polen extraído del cuerpo de obreras de cada especie de abejorro. Los granos de polen se describieron según su tamaño y morfología. La similitud de los recursos utilizados por las diferentes especies de abejorros se comparó mediante el índice de similitud y distancia de Jaccard. Se aislaron, identificaron y describieron granos de polen de 99 plantas, de las cuales Taraxacum officinale, Vallea stipularis, Senna multiglandulosa, Trifolium pratense y Trifolium repens fueron las fuentes de polen compartidas por todas las especies. La especie más generalista y que utilizó más plantas exóticas fue B. pauloensis. Se proporciona un catálogo ilustrado de polen con todos los recursos utilizados por las abejas.[Palabras clave: polinización, palinología, abejas nativas, polen] A��. Pollen catalogue of plants used by three bumblebees of the genus Bombus (Hymenoptera: Apidae) in the Eastern Cordillera of the Colombian Andes. More than 20 species of bumblebees are reported in South America, nine of them in the Eastern Cordillera of the Colombian Andes. They are known to be important pollinators, but their distribution has been decreasing due to increasing land use change; this has caused an impoverishment of Andean ecosystems. Identifying and protecting the floral resources used by wild bees is key in the management of wild areas to mitigate the impact of human activities in highly intervened areas such as cities or crops. Pollen analysis is an important tool to preserve floral resources used by bees, but it depends on having pollen catalogs that allow adequate taxonomic identifications. The objective of this study was to develop a pollen catalog of plants used by three of the most common Andean bumblebees, Bombus rubicundus, B. hortulanus and B. pauloensis. Sampling was conducted in six localities o...

Animal pollination is a regulating ecosystem service as it is the basis for plant reproduction, fruits and seeds production, thus essential for human wellbeing and ecosystem health (IPBES 2016). Around 87% of plant species in the world depend on animals (insects, birds, mammals) to some degree for pollination. In the tropical regions this percentage may reach 94% (Ollerton et al 2011). Moreover, 75% of the world's agricultural crops depends, at least partially, on animal pollination and the annual value of global crops directly affected by pollinators ranges from US$235 to US$577 billion (IPBES 2016). In Brazil, pollinators contribution to agriculture is estimated in US$14 billion per year (Wolowski et al 2019). The vast majority of pollinator species are wild insects, including species of bees, some species of flies, butterflies, moths, wasps, beetles, and thrips. Due to their dependence on floral resources such as pollen and nectar, bees, with approximately 20,000 species described worldwide, and around 5000 of which occurring in the Neotropics, represent the main group of pollinators of wild and cultivated plant species. Pollination by bees significantly contributes to the production of 1/3 of world food crops. However, the importance of other insect groups in maintaining the pollination services in natural and agricultural environments cannot be neglected (Rader et al 2016). Despite recent advances in knowledge, studies related to the role of bees and other groups of insects as pollinators remain poorly understood (Dirzo et al 2014, Eisenhauer et al 2019). To further complicate matters, in recent decades, losses of managed bee colonies in North America (BIP 2020) and many European countries (COLOSS 2020), and severe declines in wild insect populations (Eisenhauer et al 2019, Montgomery et al 2019, Sánchez-Bayo & Wyckhuys 2019) have been reported, which are of great concern to researchers, beekeepers and the general public alike. The loss of insect species is extremely worrying, especially in the tropical regions of the globe, where the vast majority of species are still unknown and the rates of deforestation and forest degradation, one of the major factor of species extinction, Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
