Basiceros scambognathus (Brown, 1949) n. comb., with the first worker and male descriptions, and a revised generic diagnosis (Hymenoptera: Formicidae: Myrmicinae)

open access: yesPapéis Avulsos de Zoologia, 2007
We propose the synonymy of the monotypic neotropical myrmicine (Basicerotini) ant genus Creightonidris Brown with Basiceros Schulz, and describe for the first time the worker and male of B. scambognathus n. comb., known thus far only by alate gynes.

WHODAS 2.0 to Assess Disability in the Rehabilitation of Individuals With Chronic Respiratory Conditions: Responsiveness and Interpretability

open access: yesPhysiotherapy Research International, Volume 31, Issue 2, April 2026.
ABSTRACT Background and Purpose Individuals with chronic respiratory conditions have physical impairments that lead to disability, but which can be alleviated with physical exercise. We aimed to examine the responsiveness and interpretability of the World Health Organisation Disability Assessment Schedule (WHODAS) 2.0 following an exercise‐based ...

Ocean Circulation Over Formigas And Ormonde Seamounts

open access: yes, 2018
ATLAS work package 1 presentation at ATLAS 3rd General Assembly Seamounts constitute an obstacle to the free ocean flow, modifying the pattern of circulation. As a result of these alterations, a variety of hydrodynamical processes and phenomena may take place at seamounts, such as Taylor columns/caps.

Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

open access: yesJournal of Zoology, Volume 328, Issue 3, Page 234-247, March 2026.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

Manejo ecológico de formigas cortadeiras Atta sexdens piriventris Emery (Hymenoptera: Formicidae) através do uso de diferentes metodologias e potências homeopáticas

open access: yesRevista Brasileira de Agroecologia, 2016
Formigas cortadeiras do gênero Atta são insetos comuns presentes na maioria dos ecossistemas Americanos. Devido ao hábito de cortar material vegetal fresco essas formigas podem causar sérios prejuízos para a agricultura.

Systematic Map of Chemical and Biological Surfactant Effects on Oxygen Mass Transfer at the Air–Water Interface

open access: yesWater Environment Research, Volume 98, Issue 1, January 2026.
This systematic review confirms that surfactants reduce oxygen transfer (kL/kLa), with concentration and hydrodynamics being critical factors. There was little diversity in the surfactants tested, and aquatic conditions were simplified, and variables (pH, viscosity) were neglected.

Proposta de atividade de campo para o ensino de biodiversidade usando formigas como modelo - doi: 10.4025/actascieduc.v32i2.11036

open access: yesActa Scientiarum. Education, 2010
As atividades de campo continuam sendo um caminho árduo para o professor, entretanto, elas representam um dos principais passos para o estudo da biodiversidade. Nosso país é considerado megadiverso, mas ensinar sobre esse tema é complexo.

Habitat Amount Shapes Ant Diversity in the Central Amazon

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...

Innovation Policy in an Emerging Economy: How Regional and Technological Disparities Moderate the Effects of a National Law

open access: yesReview of Policy Research, Volume 43, Issue 1, January 2026.
ABSTRACT The Innovation Law, enacted in Brazil in 2004, laid the regulatory and institutional foundations for the national innovation system, aiming to promote closer interaction between universities, research institutions, and industry. However, nearly two decades after its implementation, its influence on the national innovation system remains ...
