Convergent and complementary selection shaped gains and losses of eusociality in sweat bees
(2023-03-20)Sweat bees have repeatedly gained and lost eusociality, a transition from individual to group reproduction. Here we generate chromosome-length genome assemblies for 17 species and identify genomic signatures of evolutionary ... -
Convergent evolution of floral signals underlies the success of Neotropical orchids
(2013-08)The great majority of plant species in the tropics require animals to achieve pollination, but the exact role of floral signals in attraction of animal pollinators is often debated. Many plants provide a floral reward to ... -
Converging science and literature cultures: learning physics via The Little Prince novella
(2018)Primary level education follows a pedagogy model where literature and science have been historically separated. Natural children processes are disrupted, as learning based on play curiosity is completely transformed by a ... -
Cooperative elastic fluctuations provide tuning of the metal-insulator transition
(2019)Metal-to-insulator transitions driven by strong electronic correlations occur frequently in condensed matter systems, and are associated with remarkable collective phenomena in solids, including superconductivity and ... -
Cooperative signaling behavior of roost location in a leaf-roosting bat
(2010-11)Research suggests that social calls are important for conveying information about food and roost location in bats. However, no studies have specifically documented calls that are used to actively attract conspecifics to ... -
Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)
(2019)Studies of mixed-species groups of animals can reveal emergent complexities of collective behaviors. In this study we collected data on mixed-species hunting groups composed primarily of piscivorous fishes (species ... -
Copulation behaviour of Glossina pallidipes (Diptera: Muscidae) outside and inside the female, with a discussion of genitalic evolution
(Bulletin of Entomological Research (2007) 97, 1–18, 2007-04-26)If species-specific male genitalia are courtship devices under sexual selection by cryptic female choice, then species-specific aspects of the morphology and behaviour of male genitalia should often function to stimulate ... -
Copulatory behaviour and the process of intromission in Anastrepha ludens (Diptera: Tephritidae)
(Rev. Biol. Trop. 59 (1): 291-297. Epub 2011 March 01., 2011-03)Complex genitalia occur in many arthropods and in some species extreme female morphologies lead to serious mechanical difficulties for males. Tephritid flies offer examples of such complex genitalia. Because of their ... -
Copulatory dialogue: female spiders sing during copulation to influence male genitalic movements
(Animal Behaviour, 2006, 72, 413-421, 2006)Female behaviour during copulation that could function as communication with the male is probably more common than previously appreciated, but its functional significance remains little studied. Stridulation during copulation ... -
Coral Reef Bioerosion in the Eastern Tropical Pacific
(2017)Bioerosion, the weakening and erosion of hard substrates by boring, etching, and grazing organisms, is a major structuring force on coral reefs of the Eastern Tropical Pacific (ETP). Bioerosional processes are the main ... -
Coral Reef Conservation in the Eastern Tropical Pacific
(2017)This chapter reviews and evaluates coral reef conservation strategies along the eastern tropical Pacific (ETP), a narrow biogeographic region on the Pacific American coast that extends from southern Baja California, Mexico ... -

El corredor seco Centroamericano en perspectiva histórica
(2019)El artículo aborda, mediante una revisión bibliográfica, los procesos económicos y sociales desarrollados en el Corredor Seco Centroamericano, ubicado en la vertiente pacífica de América Central. Desde tiempos antiguos, ... -
La corriente en chorro de bajo nivel sobre los Llanos Venezolanos de Sur América
(2010)Utilizando observaciones del PACS-SONET (2001-2006), de radiosondeo (2007), de estaciones meteorológicas de superficie y datos del NCEP-NCAR, se analiza y documenta la estructura y variabilidad espacio-temporal de la ... -
La Corriente en Chorro del Caribe: Observaciones, modelado multifísica, interacciones multiescala e impacto regional
(2018-06)El tema central de la propuesta es el estudio de la Corriente en Chorro del Caribe (CLLJ por sus siglas en inglés). El CLLJ es uno de los mecanismos físicos más importantes para entender el clima, la variabilidad climática ... -
Corrientes marinas en algunas playas de Costa Rica
(2009)La mayoría de las muertes accidentales en Costa Rica son las muertes por sumersión, superando aún, las muertes accidentales por accidentes de tránsito. Los ríos constituyen la primera causa de muertes por sumersión, seguida ... -
Cosmological Exact Solutions Set of a Perfect Fluid in an Anisotropic Space-Time in Petrov Type D
(2016-06)In this document a set of exact solutions is obtained by using the model of a perfect fluid on an homogeneous and anisotropic space-time that belongs to (Local Rotational Symmetry) Petrov’s type D. This solutions represent ... -
Costa Rica
(2014)Costa Rica is a country with abundant and diverse freshwater ecosystems, which are influenced and characterized by different orographic precipitation regimes. This variety of habitats harbors great biological diversity, ... -
Costa Rica en el mundo: Conferencia Internacional del Meridiano (Washington, 1884)
