Does Reproductive Investment Decrease Telomere Length in Menidia menidia?

PLoS ONE, 2015
Given finite resources, intense investment in one life history trait is expected to reduce investment in others. Although telomere length appears to be strongly tied to age in many taxa, telomere maintenance requires energy. We therefore hypothesize that

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.

Transcriptional flexibility during thermal challenge corresponds with expanded thermal tolerance in an invasive compared to native fish

Evolutionary Applications, 2021
Capacity to cope with warming temperatures is a key determining factor of species' persistence under global climate change. Many successful invasive species have heightened thermal tolerance relative to their native counterparts, which may provide ...

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.

Abundance Trends, Distribution, and Habitat Associations of the Invasive Mississippi Silverside (Menidia audens) in the Sacramento–San Joaquin Delta, California, USA

San Francisco Estuary and Watershed Science, 2016
doi: http://dx.doi.org/10.15447/sfews.2016v14iss1art2Although many alien fish species have colonized the Sacramento–San Joaquin Delta (Delta), few are as pervasive and abundant as Mississippi Silversides (Menidia audens).

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.

Pulmonary arterial hypertension in pregnancy—a systematic review of outcomes in the modern era

Pulmonary Circulation, 2021
Pregnancy is hazardous with pulmonary arterial hypertension, but maternal mortality may have fallen in recent years. We sought to systematically evaluate pulmonary arterial hypertension and pregnancy-related outcomes in the last decade.

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
