Comparative Morphology and Homology of the Hyoid Apparatus and Associated Muscles in Beloniform Fishes (Teleostei: Atherinomorpha)

Journal of Morphology, Volume 287, Issue 8, August 2026.
Homology of the branchiostegals rays in atherinomorph fishes demonstrated by the position of the rays relative to the interhyoideus muscle. In beloniform outgroups, above, the two groups of branchiostegal rays are separated by the interhyoideus. In beloniform fishes, below, only one group of branchiostegal rays is present.

Trophic interactions among sympatric zooplanktivorous fish species in volume change conditions in a large, shallow, tropical lake

Neotropical Ichthyology
Significant reductions in the water volume of shallow lakes impose a restriction on species segregation promoting more interactions in the trophic relationships.

A New Species of Silverside from the Late Miocene of NW Iran [PDF]

Acta Palaeontologica Polonica, 2011
The genus Atherina (Atheriniformes, Teleostei) includes five extant brackish and marine species that inhabit the eastern Atlantic, Mediterranean Sea, Black Sea, and Caspian Sea. Several fossil species are known from the Mediterranean and Paratethyan basins. Here we describe a new fossil species, Atherina atropatiensis sp.

Water pollution from swine factory farms poses a threat to endangered and threatened species

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
Abstract Factory farms, or concentrated animal feeding operations (CAFOs), generate millions of tons of manure each year in the United States. The storage, handling, and land application of this manure leads to air, water, and climate pollution, which disproportionately impacts low‐income communities of color and poses additional public health and ...

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 ...

Spatial patterns of zooplanktivore Chirostoma species (Atherinopsidae) during water-level fluctuation in the shallow tropical Lake Chapala, Mexico: seasonal and interannual analysis

Neotropical Ichthyology
This study addresses the influence of water-level fluctuations on fish distribution at two temporal scales: seasonal (dry and rainy) and interannual (low and high volume conditions).

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.

Hidden partnerships in the dark: Cold‐water coral–fish associations in Fiordland, New Zealand

Journal of Fish Biology, Volume 108, Issue 6, Page 2171-2176, June 2026.
Abstract The ichthyofauna of the Fiordland ecosystems of southern Aotearoa New Zealand was documented during four remotely operating vehicle (ROV) dives between 100 and 350 m depth. A total of 26 fish species were documented within two fiord basins.

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.
