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 ... -
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 ... -
Corrección filológica de nombres de las especies de fauna existentes en la Reserva
(2001-11-30)Glosario didáctico sobre los animales que se localizan en la Reserva Natural Absoluta Cabo Blanco, Costa Rica. -
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, land of endless orchids
(2013-07)With almost 1,600 reported species (Karremans et al. 2012), Costa Rica has one of the richest orchid floras in tropical America, currently surpassed in total species number only by Brazil, Colombia, Ecuador and Peru (Govaerts ... -
Costa rican international cooperative biodiversity group: using insects and other arthropods in biodiversity prospecting
(Pharmaceutical Biology 37(Supplement):55–68. 1999, 1999)This paper describes the Costa Rican International Collaborative Biodiversity Group (ICBG), which was designed to introduce insects and other arthropods as a source of pharmaceutical compounds, and to generate knowledge ... -
Coupling a bio-accumulator organism and MALDI-TOF MS: an early warning detection system for microcystins in water bodies
(2017)Microcystins produced by freshwater cyanobacteria pose serious threats to human health and are a growing problem in drinking water supplies worldwide. Toxin detection and identification in water reservoirs when cyanobacterial ... -
Courtship behavior and copulation in Tengella radiata (Araneae, Tengellidae)
(2008)The first description of the courtship behavior and copulation is provided for Tengella radiata (Kulczynski 1909). The male courts the female by rocking his body and vibrating his abdomen. These behaviors seem to induce ... -
Courtship behavior of different wild strains of Ceratitis Capitata (Diptera: Tephritidae)
(Florida Entomologist 90(1) March 2007, 2007-03)Este estudio documenta diferencias en el comportamiento de cortejo de cepas silvestres de Ceratitis capitata (Wied.) provenientes de Madeira (Portugal), Hawaii (Estados Unidos de Norte América), Costa Rica y Patagonia ... -
Courtship, egg sac construction, and maternal care in Kukulcania hibernalis, with information on the courtship of Misionella mendensis (Araneae, Filistatidae)
(2013)Morphological and behavioural traits place Filistatidae basally within Araneomorphae, although some features, such as their continuing to moult after reaching adulthood, are reminiscent of mygalomorph spiders. This paper ... -
Co‑occurring epiphytic orchids have specialized mycorrhizal fungal niches that are also linked to ontogeny
(2023)Mycorrhizal symbiosis has been related to the coexistence and community assembly of coexisting orchids in few studies despite their obligate dependence on mycorrhizal partners to establish and survive. In hyper-diverse ... -
Crecimiento de Mytella guyanensis (Bivalvia: Mytilidae) en balsas flotantes
(1998)Growth of the mytilid species Mytella guyanensis was studied on a floating raft in Chira Island, inner Gulf of Nicoya, Costa Rica. Natural seed collection was done with 1.5 m long spat collectors suspended from a wooden ... -
Crecimiento y reproducción de Strombus galeatus (Gastropoda: Strombidae) en el Pacífico de Costa Rica
(1998)Strombus galeatus is a gastropod distributed from the Gulf of California in Mexico to the Galapagos Islands in Ecuador, and as other strombid species, in the costarican coast is a resource of high overfishing with no ... -
Crossoglossa sotoana (Orchidaceae: Malaxideae), a new species honoring the late Mexican botanist, Miguel Ángel Soto Arenas
(2010)Crossoglossa sotoana, a new species from Costa Rica, is described and illustrated. It is compared with Ecuadorian C. barfodii, from which it differs by the strongly undulate margins of the leaves, the resupinate flowers, ...
