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.

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

Invisible dynamics: exploring the genetic diversity of peacock bass in Brazil
OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANAIn Brazil, the introduction of non-native species into freshwater environments, such as peacock bass (Cichla spp.), was driven by aquaculture and sport fishing. These Amazonian fish possess phenotypic plasticity and resilience that facilitate their invasion and establishment in new habitats.

The impacts of biological invasions
Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Life History Consequences of the Prevalence of Aggressive Males Carrying Costly Weapons
Ecology and Evolution, Volume 16, Issue 6, June 2026.Using a soil mite system with dimorphic males, that is, aggressive, weaponized fighters and benign scramblers, we experimentally selected populations for higher proportion of fighter males for 25 generations. Populations with higher proportion of fighter males evolved faster juvenile development and higher early‐life fecundity.

Poromechanical and Crack Evolution of Olivine‐Rich Rock During Serpentinization
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Serpentinization alters the strength, fracture behavior, and rheology of ultramafic rocks, yet the coupled evolution of mineral reactions, cracking, and mechanical softening remains poorly constrained. We experimentally simulated serpentinization in dunite at 220°C and 15 MPa for 14 and 30 days and compared the reacted specimens with dry heat ...

Panama Canal expansion and shifts in fishing practices: A social‐ecological network approach
People and Nature, Volume 8, Issue 5, Page 1520-1532, May 2026.Abstract Species introductions have spiked over the past two centuries due to globalization. These introductions impact ecosystems, but may also have long‐term implications for human communities. In one of the world's hubs for global shipping, the Panama Canal, a recent canal expansion has coincided with an increase in marine fishes entering the ...
