Connecting biology, optics and nanomechanical properties in micro-wasps
(2020)Coloration in insects provides a fruitful opportunity for interdisciplinary research involving both physics and biology, and for a better understanding of the design principles of biological structures. In this research ... -
Connectivity, population structure, and conservation of Ecuadorian green sea turtles
(2017)Studies of highly migratory species that increase our understanding of the dynamics of genetic diversity, migratory routes, and genetic connectivity are essential for informing conservation actions. Genetic data for green ... -
Conservación de orquídeas en una reserva privada de Palmares, Costa Rica
(2016-12)Madre Verde Private Preserve, located in Palmares (Alajuela, Costa Rica) protects a forest relict surrounded by pastures, bushes and abandoned agriculture grounds. An inventory was conducted in this preserve to determine ... -
Conspecific and predator perception of the Red Oophaga pumilio Morph from the Central Caribbean of Costa Rica
(2020-11-04)Strawberry Poison Frogs (Oophaga pumilio) are common members of leaf litter lowland communities in Central America and exhibit several color morphs throughout their distribution. Color plays a determinant role during intra- ... -
Construction and function of the web of Tidarren sisyphoides (Araneae: Theridiidae)
(2009)In this paper, we describe the construction and function of the double sheet and tangle web of Tidarren sisyphoides (Walckenaer 1842). Web construction includes several stages: construction of the scaffolding that serves ... -
Contact calling in context: intra- and intergroup variation in vocalization rates depend on a call’s function
(2020)To maintain group cohesion while coordinating group movements, individuals might use signals to advertise the location of a route, their intention to initiate movements, or their position at a given time. In highly mobile ... -
Contrasting Patterns of Population History and Seed-mediated Gene Flow in Two Endemic Costa Rican Oak Species
(2018)Lower Central America is an important area to study recent population history and diversification of Neotropical species due to its complex and dynamic geology and climate. Phylogeographic studies in this region are few ... -
Contrasting Thermal Strategies of Montane Neotropical Bats at High Elevations
(2018)In the Neotropics, captive vespertilionid bats substantially reduce their metabolic rate at low ambient temperatures, similar to their temperate counterparts, whereas the ability of phyllostomids to lower metabolic rate ... -
Contribution to the knowledge of Costa Rican oribatid mite fauna, with supplementary descriptions of Pergalumna silvatica and P. sura (Acari: Oribatida: Galumnidae)
(2014-06)An annotated checklist of oribatid mites collected from Costa Rica in 2012 is provided. We have registered 10 species in 8 genera and 6 families. Archegozetes magnus, Kokoppia euramosa, Neoamerioppia cocuyana, Xenillus ... -
Contribution to the phylogeny and a new species of Coccodiella (Phyllachorales)
(2017-11-04)Coccodiella is a genus of plant-parasitic species in the family Phyllachoraceae (Phyllachorales, Ascomycota), i.e., tropical tar spot fungi. Members of the genus Coccodiella are tropical in distribution and are ... -
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 ... -
Coral communities of San Juan del Sur, Pacific Nicaragua
(2011)There are few environments conducive to coral growth along the Pacific coast of Nicaragua, due mostly to strong upwelling toward the south and the lack of adequate substrates toward the north. We visited 10 localities along ...
