A note on three “new” species of Xylobium (Orchidaceae; Maxillariinae) from Ruiz and Pavon’s Peruvian collections
(2016)The recent transfer to the genus Xylobium of three orchid species originally described by Ruiz and Pavón as members of Maxillaria is challenged on the basis of the extant evidence found in the herbarium and the archives ... -
A preliminary report of aquatic hyphomycetes isolated from Anzali lagoon (Gilan province, North of Iran)
(2019)Aquatic hyphomycetes equipped with a rich array of extracellular enzymes are involved in bioremediation of anthropogenic pollutants, plastics, aromatic contaminants and petroleum hydrocarbons. The current study contributes ... -
A reappraisal of Neotropical Vanilla. With a note on taxonomic inflation and the importance of alpha taxonomy in biological studies
(2020-12-23)Despite the long-standing cultural importance and botanical interest in Vanilla, many taxa belonging to the genus remain poorly understood. Vanilla species generally have broad geographical and ecological distributions. ... -
A reconsideration of the empusellous species of Specklinia (Orchidaceae: Pleurothallidinae) in Costa Rica
(2012-08-22)This paper focuses on the systematics of the Specklinia endotrachys species complex in Costa Rica. Traditionally considered a variable species, S. endotrachys is here treated as one of at least four, albeit closely related, ... -
A reexamination of Monstera oreophila Madison (Araceae: Monsteroideae) and description of two new pinkish-spathed species of Monstera from Costa Rica and Panama
(2021)Monstera gentryi from Panama and M. mittermeieri from Costa Rica are newly described, illustrated and compared with M. oreophila. The differences between the novelties and similar species are presented and an amended ... -
A review of Acianthera subgenus Brenesia (Orchidaceae, Pleurothallidinae), with a new species from Mexico
(2023)Background and Aims: Brenesia was originally proposed to accommodate an odd taxon among the Orchidaceae subtribe Pleurothallidinae. This species is characterized by its sessile leaves, secondary stems covered by inflated ... -
A Review of Breeding Systems in the Pineapple Family (Bromeliaceae, Poales)
(2023-07-05)Breeding systems play an essential role in plant sexual reproduction and influence speciation and extinction processes. However, our understanding of the breeding systems for particular neotropical angiosperm families is ... -
A review of the Costa Rican myxomycetes (Amebozoa)
(2010)There has not been a comprehensive review of the taxonomic composition of the assemblage of myxomycetes known from Costa Rica since 1975. As a result of a series of studies carried out in the country during the last decade, ... -
A revision of Axinaea (Melastomataceae)
(2015-09)Se comenta un libro (Cotton, Borchsenius & Balslev, 2014) sobre sistemática, ecología y distribución geográfica del género melastomatáceo neotropical Axinaea, que pertenece a la tribu Merianieae. Este estudio reconoce 41 ... -
A revision of the genus Muricea Lamouroux, 1821 (Anthozoa, Octocorallia) in the eastern Pacific. Part II
(2016-04-14)The species of the genus Muricea were mainly described from 1846 to 1870. After that very few contributions were published. Although the highest richness of Muricea species is in the eastern Pacific shallow waters, a ... -
A Salinity Threshold Separating Fungal Communities in the Baltic Sea
(2019)Salinity is a significant factor for structuring microbial communities, but little is known for aquatic fungi, particularly in the pelagic zone of brackish ecosystems. In this study, we explored the diversity and composition ... -
A study case of two myxomycete surveys in a fir forest of central Mexico
(2021-07-13)Field collections and laboratory isolation in moist chamber cultures are two complementary techniques widely used to record sporocarps of myxomycetes. The species recorded using either method tend to be different due to ... -
A Synecological Classification of Tropical Terrestrial Ecosystems: A first approach
(UNED, 1995)Classification of terrestrial ecosystems is a very important task in the understanding process of vegetation patterns. It is a tool of mathematical organize the available information in understandable entities without ... -

A test of color-based taxonomy in nudibranchs: Molecular phylogeny and species delimitation of the Felimida clenchi (Mollusca: Chromodorididae) species complex
(2016)Traditionally, species identification in nudibranch gastropods relies heavily on body color pattern. The Felimida clenchi species complex, a group of brightly colored Atlantic and Mediterranean species in the family ... -
A test of the Acoustic Adaptation Hypothesis in three types of tropical forest: degradation of male and female Rufous-and-white Wren songs
(2016)Many animals produce complex vocalizations that show pronounced variation between populations. The Acoustic Adaptation Hypothesis helps to explain this variation, suggesting that acoustic signals are optimized for transmission ... -
A time- and cost-effective strategy to sequence mammalian Y Chromosomes: an application to the de novo assembly of gorilla Y
(2016-02)The mammalian Y Chromosome sequence, critical for studying male fertility and dispersal, is enriched in repeats and palindromes, and thus, is the most difficult component of the genome to assemble. Previously, expensive ... -
