Bretschneidera sinensis is an endangered species that is mainly distributed in South China. As a tertiary relict and the single species in the Bretschneideraceae family, it has a high conservation value. To investigate the influence of human disturbance on its mating system, 63 new microsatellites were developed using restriction-site-associated DNA sequencing and their polymorphisms were tested on 30 samples from one population. Among the 63 microsatellites, the number of alleles per locus ranged from 2 to 16. The observed and expected heterozygosities ranged from 0.133 to 0.967 and from 0.127 to 0.912, respectively. These microsatellites may be used for studying the mating system of B. sinensis as well as the within-population hereditary structure.

In January 2024, the Australian state of Victoria committed to ending native forest logging six years ahead of schedule, a decision that has been advocated for by scientists and conservationists for decades. However, the direct benefits for threatened species from this policy change has not been quantified. This study assesses the spatial overlap between areas approved for logging and the habitats of nationally listed threatened species, to estimate the potential impacts of continued logging and the likely benefits of its cessation.

The hawksbill turtle, Eretmochelys imbricata, has been at risk of extinction for more than 40 years and remains critically endangered. While nesting beach protection is important for hatchling production, identifying inter-nesting, migratory, and foraging habitats is crucial for mitigating threats to population recovery. We report the use of satellite telemetry to monitor movements of 15 hawksbill turtles in the Western Caribbean.

The Golfão Maranhense is an extensive estuarine complex that provides nursery grounds and other habitats for several fish species, as well as a wealth of resources for the coastal and estuarine artisanal fisheries of the Maranhão state, in northern Brazil. The present study provides a comprehensive inventory of marine and estuarine teleost fishes of the Golfão Maranhense based on field samplings, analyses of voucher specimens from local collections and literature data. This inventory presents a total of 163 species of teleosts belonging to 107 genera, 57 families and 27 orders.

Population dynamics are governed by the so-called four BIDE processes: birth, immigration, death, and emigration. However, most population models fail to explicitly consider all four processes, which may hinder a comprehensive understanding of how and why populations change over time. The advent of Integrated Population Models (IPMs) and recent developments in spatial mark-recapture models have enabled deeper insights into demography and dispersal.

Hatchery supplementation is frequently employed during the conservation and recovery of imperilled salmon populations. At the smolt stage, hatchery rearing practices often produce individuals that are larger than wild conspecifics. Under this 'bigger is better' strategy, it is assumed that larger fish are less susceptible to predation during migration.
