Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

Tripartite Symbiosis Between Legumes, Arbuscular Mycorrhizal Fungi and Nitrogen Fixing Rhizobia: Interactions and Regulation

Plant, Cell &Environment, Volume 49, Issue 7, Page 3789-3807, July 2026.
ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...

Little devils of Neotropical forests: A first molecular phylogeny of stygnid harvestmen with UCE‐museomics and a gigamatrix approach (Arachnida, Opiliones, Stygnidae)

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First family‐wide phylogenomic framework of Stygnidae using UCE‐museomics and a gigamatrix approach establishes a novel three‐subfamily classification, erecting the new subfamily Auraninae subfam. nov. Signatures of severe incomplete lineage sorting and short deep internodes suggest a rapid early‐burst Neotropical radiation, driving phylogenetic ...

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

Zoologica Scripta, Volume 55, Issue 4, Page 568-588, July 2026.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,
