Optimal irradiation parameters for the development of the sterile insect technique in the seedcorn maggot Delia platura (Diptera: Anthomyiidae)

Pest Management Science, EarlyView.
X‐ray irradiation of Delia platura pupae showed that 20 Gy induces high sterility while maintaining male quality and competitiveness, establishing optimal parameters for sterile insect technique implementation in North America. Abstract BACKGROUND The seedcorn maggot, Delia platura Meigen (Diptera: Anthomyiidae), is a sporadic but economically ...

Genomic resources for the monitoring and management of Tometes trilobatus, Hoplias aimara and Myloplus rhomboidalis, three exploited freshwater fish species in French Guiana

Knowledge and Management of Aquatic Ecosystems
The Neotropical region, hosts a quarter of all freshwater fish species, while providing important food resources for local human populations. The management of neotropical freshwater ecosystems is thus of primary importance for both biodiversity ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Maintenance and Management of Breeders of Neotropical South American Species in Laboratories

The aquaculture industry in several South American countries has witnessed a decline in the production of Neotropical South American fish species due to the limited availability of technological packages and underutilization of existing knowledge ...

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Development of a reliable PCR‐based protocol for molecular sexing of king vultures Sarcoramphus papa

Wildlife Biology, EarlyView.
The king vulture Sarcoramphus papa is a large Neotropical scavenger that lacks external sexual dimorphism, complicating demographic, ecological, and conservation studies. Reliable sex identification is therefore essential, particularly for wild and managed populations. In this study, we assessed and optimized a PCR‐based molecular sexing protocol for S.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Diet shift of Red Belly Pacu Piaractus brachypomus (Cuvier, 1818) (Characiformes: Serrasalmidae), a Neotropical fish, in the Sepik-Ramu River Basin, Papua New Guinea

Neotropical Ichthyology
Introduction of fish species is a globally widespread practice that causes losses of native species and homogenization of diversity within and across continents. Diet assessments are important tools to depict the ecological function of species introduced

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.
