Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, EarlyView.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Magnetic and electrical properties in Co-doped KNbO3 bulk samples

open access: yesAIP Advances, 2018
Multiferroic materials exhibit in the same phase at least two of the ferroic properties: ferroelectricity, ferromagnetism, and ferroelasticity, which may be coupled to each other.

An updated checklist of Culicoides Latreille, 1809 biting midges from the highlands of eastern Democratic Republic of the Congo Une liste mise à jour des moucherons piqueurs de Culicoides Latreille, 1809 des hautes terres de l'est de la République démocratique du Congo

open access: yesMedical and Veterinary Entomology, EarlyView.
The highlands of eastern Democratic Republic of the Congo (DRC) are home to critically endangered eastern gorillas (Gorilla beringei). Climate change could increase the abundance and distribution of Culicoides‐borne diseases. We utilized morphological and molecular techniques to identify Culicoides spp.

Um cimento mais sustentável frente a um ataque severo por sulfatos [PDF]

open access: yes, 2007
A necessidade de encontrar um cimento plenamente resistente aos sulfatos e que também seja ambientalmente sustentável levou a que se analisasse o comportamento de um cimento sulfoaluminato-belítico (SAB) frente a um ataque severo por sulfato de sódio e ...

Magnetic field dependence of the density of states in the multiband superconductor $\beta$-Bi$_2$Pd [PDF]

open access: yes, 2015
We present very low temperature scanning tunneling microscopy (STM) experiments on single crystalline samples of the superconductor $\beta$-Bi$_2$Pd. We find a single fully isotropic superconducting gap.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

open access: yesNew Phytologist, EarlyView.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Pressure effects in the triangular layered cobaltites NaxCoO2

open access: yes, 2007
We have measured transport properties as a function of temperature and pressure up to 30GPa in the NaxCoO2 system. For the x=0.5 sample the transition temperature at 53K increases with pressure, while paradoxically the sample passes from an insulating to

Do Energetic Challenges Mimicking Missed Foraging Encourage Torpor Use by a Neotropical Bat?

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We experimentally tested whether Merriam's long‐tongued bat (Glossophaga mutica), a Neotropical nectarivorous species, uses heterothermy in response to reduced energy intake. We found that energetically challenged bats maintained subcutaneous temperatures significantly closer to roost temperature during the daytime inactive period.
