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 ... -
Myxomycete diversity in Costa Rica
(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 ... -
Myxomycetes associated with bryophyte mats in San Ramón, Costa Rica
(2022)Myxomycete-bryophyte associations have been studied mostly in temperate regions of the world. Data from tropical regions are much more limited. The interesting landscape configuration of the San Ramón area in Costa Rica, ... -
Myxomycetes associated with three different types of Neotropical urban landscapes
(2022-12-05)Urban ecology is a research field gaining momentum due to contextual pressures to study macroecological effects on biodiversity. Herein, we evaluated the occurrence of myxomycetes in three urban Neotropical environments ... -
Myxomycetes collected in the eastern United States and patterns of relative biodiversity
(2020-01-05)A total of 68 315 digitised records of myxomycetes from the eastern United States were compiled from all readily available sources. After cleaning the database for inconsistencies, 58 594 records remained that were ... -
Myxomycetes of Thailand
(2010)After the first report of myxomycetes from Thailand in 1902, there were only a few papers dealing specifically with these organisms over the following 85 years. In 2004, intensive ecological studies of myxomycetes began ... -
Myxomycetes within ecotones in temperate and tropical forests
(2021)Ecotones are interesting portions of forests where microorganisms can be studied for monitoring and diversity purposes. Given the faster life cycle of these organisms, their study in such a context is important to develop ... -
N-[3-(Prop-1-yn-1-yl)phenyl]benzenesulfonamide
(2019)In the title sulfanilamide derivative, C15H13NO2S, which shows significant activity against Staphylococcus aureus and Escherichia coli, the dihedral angle between the planes of the aromatic rings is 62.15 (19)° and the ... -
N-Formyl-Perosamine Surface Homopolysaccharides Hinder the Recognition of Brucella abortus by Mouse Neutrophils
(2016-06)Brucella abortus is an intracellular pathogen of monocytes, macrophages, dendritic cells, and placental trophoblasts. This bacterium causes a chronic disease in bovines and in humans. In these hosts, the bacterium also ... -
N-terminal peptide of myotoxin II from Bothrops asper venom enhances the activity of endothelin converting enzyme and neprilysin
(2016)Neprilysin (NEP) and endothelin converting enzyme-1 (ECE-1) are two enzymes that degrade amyloid beta in the brain. Currently there are no molecules to stimulate the activity of these enzymes. Here we report, the discovery ... -
