Direct introduction of cloned DNA into the sea urchin zygote nucleus, and fate of injected DNA [PDF]

open access: yes, 1988
A method is described for microinjection of cloned DNA into the zygote nucleus of Lytechinus variegatus. Eggs of this species are unusually transparent, facilitating visual monitoring of the injection process.

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

open access: yesThe Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Contribuição ao estudo da anatomia macroscópica dos rins e das estruturas vasculares sanguíneas no hilo renal do bicho-preguiça (Bradypus variegatus)

open access: yesMedicina Veterinária, 2020
Devido à ação antrópica sob o habitat natural do Bradypus variegatus, esta espécie encontra-se em risco de extinção. Um dos principais pontos para a conservação de espécies em extinção é conhecer sua anatomia e fisiologia. Porém, para o B.

No compromise between metabolism and behavior of decorator crabs in reduced pH conditions. [PDF]

open access: yes, 2019
Many marine calcifiers experience metabolic costs when exposed to experimental ocean acidification conditions, potentially limiting the energy available to support regulatory processes and behaviors. Decorator crabs expend energy on decoration camouflage

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

The metabolic response of the Bradypus sloth to temperature [PDF]

open access: yesPeerJ, 2018
Poikilotherms and homeotherms have different, well-defined metabolic responses to ambient temperature (Ta), but both groups have high power costs at high temperatures.

Red Algal Sulfated Galactan Binds and Protects Neural Cells from HIV-1 gp120 and Tat

open access: yesPharmaceuticals, 2021
The potential neuroprotective capacity of four different sulfated glycans: Botryocladia occidentalis-derived sulfated galactan (BoSG) (MW > 100 kDa), Lytechinus variegatus-derived sulfated fucan (LvSF) (MW~90 kDa), high-molecular weight dextran sulfate ...

Impacts of large herbivores on mycorrhizal fungal communities across the Arctic

open access: yesEcography, EarlyView.
Mycorrhizal fungi play an integral role in nutrient and carbon cycling in soils, which may be especially important in the Arctic, one of the world's most soil carbon‐rich regions. Large mammalian herbivores can influence these fungi through their impacts on vegetation and soil conditions, however the strength and prevalence of these interactions in the
