Silverside gold mine? Restored tidal habitats host abundant invasive fishes in a novel California marsh (U.S.A.)

Restoration Ecology, EarlyView.
Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...

Effects of Broiler Breeder Age on Egg Quality, Incubation Performance, and Early Progeny Physiological and Muscle Fiber Development

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 4, Page 571-581, July 2026.
ABSTRACT This study evaluated the effects of breeder hen age on the incubation performance, embryonic development, and progeny quality of Cobb500 broiler breeders at 39, 51, and 69 weeks of age. A total of 870 eggs were collected, of which 810 were incubated; these were assigned to a completely randomized design with three treatments and nine ...

Feeding Ecology of Gould's Arrow Squid Nototodarus gouldi (Cephalopoda: Ommastrephidae) in Aotearoa New Zealand Waters

New Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Squids are important components of marine ecosystems because of their role as both predator and prey. Across the Tasman Sea, Gould's arrow squid (Nototodarus gouldi) is a commercially targeted ommastrephid squid that supports an economically important fishery.

Introgression between ecologically distinct species following increased salinity in the Colorado Delta- Worldwide implications for impacted estuary diversity [PDF]

PeerJ, 2017
We investigate hybridization and introgression between ecologically distinct sister species of silverside fish in the Gulf of California through combined analysis of morphological, sequence, and genotypic data. Water diversions in the past century turned

Diplostomatid Metacercariae in the Brain of Silversides from Lake Riñihue, Chile [PDF]

Journal of Wildlife Diseases, 1997
The tissue locations and effects produced by metacercariae of Diplostomum (Austrodiplostomum) mordax and Tylodelphys destructor in the brain of 30 silversides (Basilichthys australis) from Lake Riñihue in Chile, were evaluated. Metacercariae were mainly observed in the interlobular infoldings, meninges and ventricles of the brain. The prevalence was 18

Recent Polygenic Adaptation in Heavily Fished Malawi Cichlids

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Intense fishing pressure can drive rapid evolution in wild populations, yet the underlying genomic mechanisms often remain elusive. Here, we investigate the genomic consequences of five decades of intense harvesting on the cichlid fish Copadichromis mloto in Lake Malombe, Malawi.
