Mosses as spore traps for myxomycetes
(2020-07-06)Small-mesh nylon bags filled with autoclaved samples of mosses were placed out in the field in northwest Arkansas and central Costa Rica to assess the extent to which mosses could serve as spore traps for myxomycetes. The ... -
Movements and morphology under sexual selection: tsetse fly genitalia
(Ethology Ecology & Evolution 22: 385–391, 2010, 2010-04-17)SHÖN (2009, Ethology Ecology & Evolution 21: 161–172) pointed out that in order to understand the functional morphology of sexually selected structures that are used as signaling devices in birds, it is crucial to ... -
Multilocus Sequence Analysis for Assessment of the Biogeography and Evolutionary Genetics of Four Bradyrhizobium Species That Nodulate Soybeans on the Asiatic Continent
(2008)A highly supported maximum-likelihood species phylogeny for the genus Bradyrhizobium was inferred from a supermatrix obtained from the concatenation of partial atpD, recA, glnII, and rpoB sequences corresponding to 33 ... -

Muscarinic and glutamatergic regulation of self-grooming behavior and ultrasonic vocalizations in the context of open-field habituation in rats
(2019)We tested whether pharmacological impairment of OF-habituation after the administration (i.p.) of scopolamine (SCP; muscarinic antagonist) or MK-801 (MK; NMDA antagonist) was able to disrupt or alter grooming syntaxes. ... -
Mycelial inhibition of Trichoderma spp. (Hypocreaceae) isolated from the cultivation of Pleurotus ostreatus (Pleurotaceae) with an extract of Pycnoporus sp. (Polyporaceae)
(2020-01-07)Background and Aims: The production of edible fungi is affected by bacterial, fungal and viral diseases, which very often cause large losses. In the production of mushrooms of the genus Pleurotus, the fungi of Trichoderma ... -
Mycorhizal diversity of epiphytic orchids in a hyperdiverse tropical forest: insights on temporal and life stage changes
(2018)Few studies have examined the diversity of fungal communities of epiphytic orchids from hyperdiverse tropical forests and its temporal dynamics. This study aims to describe the fungal diversity associated with three tropical, ... -
Mycorrhizal and endophytic richness and colonization in Cedrela odorata L., in agroforestry systems and secondary forest from southeastern Costa Rica
(2023-01-25)The roots of different forest species showmixed colonization by arbuscular mycorrhizal fungi(AMF) and dark septate fungi (DSE). In temper-ate ecosystems, AMF colonization and communitystructure change according to plantation ... -
Myoxanthus Poepp. & Endl.
(2020)The genus Myoxanthus was created by Eduard Poeppig and Stephan Endlicher in 1836 when they described M. monophyllus on the basis of a plant collected by Poeppig during his journey to South America, in the region of Huánuco, ... -
Myoxanthus vittatus (Orchidaceae), a new species from Costa Rica
(2001-10)The taxonomic position of Myoxanthus Poepp. & Endl. (Orchidaceae: Pleurothallidinae) is discussed and Silenia Luer is maintained as a subgenus of Myoxanthus. A new species of Myoxanthus is described and illustrated. ... -
Mysidopsis gemina n. sp. (Crustacea: Mysida: Mysidae) from the northern Pacifc coast of Costa Rica
(2019-12-02)Mysidopsis gemina n. sp. is described from protected and exposed beach habitats in the provinces of Puntarenas and Guanacaste on the northern Pacifc coast of Costa Rica. Morphologically, M. gemina most closely resembles ... -
The mystery of how spiders extract food without masticating prey
(2006)Standard accounts of how spiders obtain food without masticating their prey are probably largely wrong. Species in the families Uloboridae, Thomisidae, Araneidae and Theridiidae do not inject digestive fluid into the prey’s ... -
Myxomycete assemblage turnover across a moisture and elevation gradient in Costa Rica
(2021-07-13)The formation of sporocarps in myxomycetes depends on environmental characteristics, among which, moisture and temperature seem to be relevant in tropical areas. Since temperature is linked to elevation, the effect of both ... -
Myxomycete colonization on translocated and non-translocated dead leaves from temperate and tropical forests
(2020-11)Samples of dead leaves on the forest floor were collected from a locality in central Costa Rica and another locality in northwest Arkansas in the United States and then were placed in fine-mesh nylon bags, autoclaved and ... -

(2018-04)An updated analysis of myxomycete diversity in Costa Rica is provided herein as a product of an extensive data mining-based study intended to normalize the information on myxomycetes from that country. Within the context ... -
Myxomycete ecology along an elevation gradient on Cocos Island, Costa Rica
(2008)The marine biota of Cocos Island is well known; however, the terrestrial biota is poorly understood. In an effort to document the myxomycetes of the island and to determine their ecological distribution along an elevation ... -
Myxomycete ecology in urban areas: rapid assessment from two cities
(2021-02-25)Urban ecology has been an understudied topic in myxomycete research. For that reason, the present investigation aimed to generate data related to myxomycetes in urban areas of the Neotropical region. With an approach of ...
