Ecological trait divergence over evolutionary time underlies the origin and maintenance of tropical spider diversity

open access: yesEcography, Volume 2025, Issue 4, April 2025.
Relative to its size, tropical Asia is likely to be the richest region in terms of biodiversity. However, the factors of species diversity formation and maintenance in Southeast (SE) Asia and neighboring regions remain poorly understood. Here we infer the evolutionary relationships within psilodercid spiders by incorporating fossil information into a ...

Evaluating endophyte‐rich leaves and leaf functional traits for protection of tropical trees against natural enemies

open access: yesFunctional Ecology, Volume 39, Issue 2, Page 371-389, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants use physical barriers and chemical compounds to defend themselves against natural enemies. For instance, tough leaves are considered to be better defended than soft leaves, part of a spectrum of defences defined by functional traits such as leaf chemistry ...

La defensa de Passiflora caerulea por hormigas reduce el número de huevos y larvas de Agraulis vanillae, pero no el daño por herbivoría

open access: yesEcología Austral, 2018
En las comunidades ecológicas, las especies pueden participar de forma simultánea en interacciones interespecíficas de distinto tipo (e.g., depredación, polinización y dispersión), lo que implica que la ocurrencia de una interacción pueda afectar el ...

Lacanian realism: Literatura de la crisis and Ángel Zapata's aesthetic of failure

open access: yesOrbis Litterarum, Volume 80, Issue 1, Page 74-93, February 2025.
Abstract Since Spain's socio‐economic crisis of the 2010s, critical approaches have analysed the surge in literature which addresses the crisis's political and socio‐economic consequences. These approaches have largely assessed literature by its capacity to raise readers' awareness of capitalist exploitation.

Historia taxonómica de las hormigas

open access: yesInventio, 2020
A lo largo de los años se han hecho estudios sobre relaciones filogenéticas de las hormigas, éstos han ido cambiando con el tiempo porque se van aumentando nuevos conocimientos empíricos y objetivos para contribución de los anteriores estudios. La historia filogenética de las hormigas se puede dividir en dos etapas, la precladística y la cládistica ...

Three Novel Spider Genomes Unveil Spidroin Diversification and Hox Cluster Architecture: Ryuthela nishihirai (Liphistiidae), Uloborus plumipes (Uloboridae) and Cheiracanthium punctorium (Cheiracanthiidae)

open access: yesMolecular Ecology Resources, Volume 25, Issue 1, January 2025.
ABSTRACT Spiders are a hyperdiverse taxon and among the most abundant predators in nearly all terrestrial habitats. Their success is often attributed to key developments in their evolution such as silk and venom production and major apomorphies such as a whole‐genome duplication.
