The Mesolithic period has a long history of study in the Cantabrian region (Northern Iberia) due to the relatively high concentration of human remains dating to this period. Previous analysis of stable carbon and nitrogen isotopes focussed on bone collagen, useful in broadly characterising Mesolithic diet, and particularly in identifying distinct inland and coastal diets. But this long-term average view does not permit the stu...

A 10-week feeding experiment was conducted to evaluate the effects of replacing fishmeal with cricket meal on the productive performance and transcriptional responses of genes related to nutrient metabolism and growth of blue tilapia (Oreochromis aureus). Five conventional tilapia feeds were formulated to replace fishmeal with cricket meal. Control diet (CD) was formulated with 20% fishmeal, and four diets gradually replaced f...

Accurate knowledge of the global distribution of non-indigenous species (NIS) is essential for understanding their invasion dynamics and for implementing timely management measures. This study reports the first records of the marine amphipod Aoroides longimerus, putatively native to the East Asian coast, in Italy (2018), Spain (2019) and Tunisia (2022) and provides the earliest documented record of the species in its introduce...

In this study we have compiled the information from official databases about Iberian ibex, Capra pyrenaica , hunting yields, hunting trophies and hunting licenses in the Spanish regions where the species is present and hunted. Such quotas showed an increasing trend between 2005–2021 and, on average, during this period, ≈ 6400 animals were yearly harvested. Despite this number decreased in 2019 and 2020 (in this last year, main...
