Influence of Photoperiod on Productive Gains and Immune Resistance During the Larval Stage of the Neotropical Fish Trachelyopterus galeatus (Linnaeus, 1766)

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
This study evaluated the effect of photoperiod as a productive strategy during the larviculture of the neotropical species Trachelyopterus galeatus. A total of 560 postlarvae, with an average total length and weight of 6.61 ± 0.33 mm and 2.36 ± 0.10 mg, respectively, were randomly assigned to seven photoperiod treatments, each four replicates: (0L:24D)

HotSHOT Extraction Is a Fast, Economical, and Efficient Method for Obtaining Tardigrade gDNA

open access: yesPsyche: A Journal of Entomology, Volume 2025, Issue 1, 2025.
Among the main problems in obtaining genomic DNA (gDNA) from small invertebrates such as tardigrades are the low amount of gDNA obtained per specimen, as well as the complexity of steps and number of reagents used for gDNA extraction. For example, the extraction method with chelating resin is the most used as an alternative to commercial kits for ...

Riding the wetland wave: Can ducks locate macroinvertebrate resources across the breeding season?

open access: yesEcology and Evolution, Volume 14, Issue 6, June 2024.
Nektonic macroinvertebrate density varies across wetland types and over time during the waterfowl breeding season, with basin wetlands harboring the highest density and the most stable resources. Waterfowl pairs are able to track these densities and are found in the greatest numbers in the wetlands with the highest food density during the breeding ...

Biotic interactions vary across species' ranges and are likely conserved through geological time

open access: yesJournal of Biogeography, Volume 51, Issue 5, Page 894-908, May 2024.
Abstract Aim The evolutionary interactions between western spadefoot toads (genus Spea) represent a textbook example of character displacement, facilitated by dietary specialization of one Spea species on fairy shrimp (Anostraca) when all three co‐occur. The aim of this study is to understand the covariation between predator (Spea) and prey (Anostraca)
