Wasp florivory decreases reproductive success in an epiphytic bromeliad
(2009)Flower predation or florivory may alter the sexual expression, floral display, and reduce the reproductive success in plants. In this article, we estimated the effect of florivory on the reproductive success of the epiphytic ... -
Water quality conditions on coral reefs at the Marino Ballena National Park, Pacific Costa Rica
(2009)Marino Ballena National Park is located in an area thought to be chronically affected by high terrigenous sediment and nutrient loads, and high temperatures. Five coral reefs at MBNP were monitored monthly between August ... -
Web building behavior in a wall spider (Oecobiidae) suggests a close relationship with orb-weavers
(2022)Behavior is often phylogenetically informative and detailed descriptions of behavior have been used to support taxonomic relationships in several groups, such as birds, lizards, and arthropods. Web building behavior has ... -
What can myxomycetes tell us about floricolous microbial systems?
(2017-02)The study described herein was conducted in Costa Rica in an effort to generate baseline data on the association between tropical inflorescences and a group of microorganisms known as myxomycetes. The assemblage structure ... -
What’s the date?
(2022)Rafaël Govaerts, Adam P Karremans and Julian Shaw go to lengths to establish the effective publication dates of some orchid names in the journal Revista Guatemalensis -
When a little is enough: cocoon web of Kapogea cyrtophoroides (Araneae: Araneidae) induced by Hymenoepimecis heidyae (Ichneumonidae: Pimplinae)
(2018)The final instar larvae of the koinobiont ectoparasitoids in the Polysphincta group of genera induce their host spiders to construct webs that protect the wasp pupa during its development. It has been hypothesized that ... -
When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor
(2013-11)For species characterized by philopatry of both sexes, mate selection represents an important behaviour for inbreeding avoidance, yet the implications for gene flow are rarely quantified. Here, we present evidence of male ... -
When the absence of evidence is not the evidence of absence: Nasa (Loasaceae) rediscoveries from Peru and Ecuador, and the contribution of community science networks
(2023)Documentation of plant taxa has long been subject to the temporal and spatial selectivity of professional research expeditions, especially in tropical regions. Therefore, rare and/or narrowly endemic species are sometimes ... -
Widespread Occurrence of Black-Orange-Black Color Pattern in Hymenoptera
(2019)Certain color patterns in insects show convergent evolution reflecting potentially important biological functions, for example, aposematism and mimicry. This phenomenon has been most frequently documented in Lepidoptera and ... -
Widespread tropical agrowastes as novel feedstocks for biochar production: characterization and priority environmental uses
(2020)Biochar, a carbon-rich pyrolytic product, has demonstrated positive results as a soil improver and carbon sequestration agent. Its production could be an appropriate and innovative practice for agricultural waste management ... -
William C. Burger (1932-2022), uno de los grandes en la florística de Costa Rica
(2023-10-06)El botánico estadounidense William C. Burger (1932-2022) fue uno de los principales estudiosos de la flora de Costa Rica en el siglo XX. Él trabajó en Field Museum, Chicago. En Costa Rica hizo numerosos viajes de exploración ... -
Wind creates crown shyness, asymmetry, and orientation in a tropical montane oak forest
(2020)In a cloud forest dominated by Quercus costaricensis, the gap size between the crowns was consistent and crowns were asymmetrical, being elongated perpendicular to the prevailing wind direction. A wind storm of 20 m/s ... -
With great biodiversity comes great responsibility: The underestimated diversity of Epidendrum (Orchidaceae)
(2021-12-31)Epidendrum (orchidaceae) has been suggested to be a promising model system for evolutionary and ecological studies in the neotropical region. given its species diversity, the broad biogeographical and ecological range, and ... -
x Cochlezella costaricensis, a name for a rare natural hybrid in the Zygopetalinae (Orchidaceae)
(2015)A new nothospecies in the subtribe Zygopetalinae (Orchidaceae), × Cochlezella costaricensis, representing a cross between Cochleanthes aromatica and Warczewiczella discolor, is described and illustrated from Costa Rica, ... -
Xantismo en peces cíclidos (Cichliformes: Cichlidae) costarricenses, y variación ontogenética en Parachromis dovii
(2021)Introducción: El xantismo o xantocromismo es una anomalía fenotípica que se evidencia por la producción predominante de xantina, un pigmento que le da al organismo una coloración amarillenta. En Costa Rica existen pocos ... -
Xylobium Lindl.
(2022)Xylobium derives from the Greek words xylon, wood, and bios, life, meaning “life on the wood or tree”. Though, it seems contradictory that Lindley chose a name referring to the epiphytic habit of the plant because the ... -
