Biogeografía cladística: conceptos básicos

open access: yesArbor: Ciencia, Pensamiento y Cultura, 1997
La biogeografía cladística asume una correspondencia entre relaciones taxonómicas y relaciones de área. Un análisis de biogeografía cladística implica tres etapas: (1) la construcción de cladogramas taxonómicos de áreas basados en los cladogramas de los ...

Phylogeny and taxonomy of the Australasian Zygaenula Doleschall, 1858 (Diptera: Platystomatidae) with a description of a new species

open access: yesAustral Entomology, Volume 64, Issue 4, November 2025.
Abstract Zygaenula Doleschall, 1858 and Mesoctenia Enderlein, 1924 syn. nov. are small genera restricted to the Australasia region. Here, both genera are considered synonymous, supported by the synapomorphy width of frons, in relation to height, more than two times. A new species, Zygaenula mcalpinei sp. nov.

Seasonal Forest Resources Support Fish Biomass in Floodplain Lakes of an Amazonian Tributary

open access: yesFreshwater Biology, Volume 70, Issue 11, November 2025.
ABSTRACT The Flood Pulse Concept is a foundational ecological theory that emphasizes the critical role of lateral connectivity between a river channel and its floodplain. Many tropical rivers inundate the surrounding floodplain in the flood stage, thereby receiving large amounts of terrestrial organic matter that can be decomposed by microbes and ...

Genomic Data Are Not Commodities: Advocating for Collective Responsibility in Open Science

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT The availability of genomic and genetic data is fundamental to advancing biogeographical research, particularly in biodiversity‐rich but data‐poor regions such as the South Atlantic. Yet, despite increasing mandates for open science, researchers face significant barriers to accessing datasets from published studies.

The Role of Fish in Nutrient Recycling Across a Conservation Gradient in Neotropical Streams

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Fish play a crucial role in nutrient recycling within various aquatic ecosystems, but how their contribution varies across streams with different levels of disturbance remains poorly understood. In our study, we investigated the role of fish assemblage in nutrient cycling within eight Neotropical streams characterised by varying degrees of ...

Knowledge from non‐English‐language studies broadens contributions to conservation policy and helps to tackle bias in biodiversity data

open access: yesJournal of Applied Ecology, Volume 62, Issue 9, Page 2148-2162, September 2025.
Collecting data from local sources markedly further strengthens global biodiversity databases by adding species not previously included in international datasets. Furthermore, the addition of these data helps to understand spatial and temporal biases that potentially influence abundance trends at both national and global levels.

Experimentos em biogeografia

open access: yesGeografia (Londrina), 2011
A utilização de experimentos não só na Biogeografia, mas também em outras áreas da geografia como a Geomorfologia por exemplo, está sendo muito discutida ultimamente, pelo menos é o que pudemos perceber no Seminário "Experimentos em Geografia Física ...
