Oxic and Anoxic Organic Polymer Degradation Potential of Endophytic Fungi From the Marine Macroalga, Ecklonia radiata
(2021-10-18)
Cellulose and chitin are the most abundant polymeric, organic carbon source globally. Thus, microbes degrading these polymers significantly influence global carbon cycling and greenhouse gas production. Fungi are recognized ...
Myxomycetes within ecotones in temperate and tropical forests
Mixomicetes en ecotonos forestales de bosques templados y tropicales
Mixomicetos em ecótonos florestais de bosques temperados e tropicais
(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 ...
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 ...
Detection of a synthetic sex steroid in the American crocodile (Crocodylus acutus): Evidence for a novel environmental androgen
(2017-08)
Endocrine-disrupting contaminants (EDC's) are well known to alter sexual differentiation among vertebrates via estrogenic effects during development, particularly in organisms characterized by
temperature-dependent sex ...
Tie them up tight: wrapping by Philoponella vicinaspiders breaks, compresses and sometimes kills their prey
(2006)
We show that uloborid spiders, which lack the poison glands typical of nearly all other spiders, employ thousands of wrapping movements with their hind legs and up to hundreds of meters of silk line to make a shroud that ...
The role of learning, acoustic similarity and phylogenetic relatedness in the recognition of distress calls in birds
(2021-05)
Many groups of vertebrates produce distress calls when attacked by predators as a last attempt to survive. However, few studies investigate whether recognition of distress calls involves learning or acoustic similarity to ...
Una Nueva especie del género Karnyothrips Watson (PHLAEOTHRIPIDAE:TUBULIFERA)
A new species of genus Karnyothrips Watson (Phlaeothripidae: Tubulifera)
(Entomología mexicana, vol. 8, 2009)
En este trabajo se describe una nueva especie de insecto, para el oriente de México (Xalisco, Nayarit) que se recolectó en cultivares de aguacate. Su nombre es Karnyothrips maurilia
Microplastic ingestion by a herring Opisthonema sp. in the Pacific coast of Costa Rica
(2020-07)
Current knowledge of the presence of microplastics (MP) in marine species in tropical areas is still limited. The presence of MP was examined in the gastrointestinal content of 30 filter feeders of the herring Opisthonema ...
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 ...
Maternally derived chemical defenses are an effective deterrent against some predators of poison frog tadpoles (Oophaga pumilio)
(2014)
Parents defend their young in many ways, including provisioning chemical defences. Recent work in a poison frog system offers the first example of an animal that provisions its young with alkaloids after hatching or birth ...
