This study aims to determine the age and growth characteristics of living in the Northeastern Mediterranean Sea and to present data that can provide a comparison with previous studies on the same subject. A total of 255 long-nose skates at a total length of 12.2-93.5 cm and weight of 8.34-3828 g were collected as non-target species from a commercial fishing boat. The male-female ratio was determined as 1:1.27. Using the von Bertalanffy equation and the Gompertz or logistic growth models, the growth parameters of were estimated as L∞ = 154.0, K = 0.064, t = -1.622; L∞ = 104.0, K = 0.35, = 4.99; L∞ = 128.40, K = 0.19, = 4.39 for all individuals, respectively. Maximum absolute growth was calculated as 9.33 cm at 5-6 years of age. Maximum relative growth at 1-2 years of age was estimated as 36.39%. Both absolute and relative growth were minimal in the 11-12 age group. The highest condition factor value was estimated as 0.416 in the 8-year-old group. As a result, the growth data of long-nose skates were obtained for the first time in the Northeastern Mediterranean Sea.

Unlabelled: During the Iron Age, north-eastern Iberian communities relied on crop cultivation and animal husbandry for their subsistence. The latter was mainly focused on caprine, with sheep being prominent due to their suitability to the Mediterranean climate, orography, and environment. Despite the pivotal role of sheep in livestock husbandry, information on Iberian communities' feeding strategies for this species is limited.
View Article and Find Full Text PDFTwo species of stenopodidean shrimps are newly recorded from the tropical eastern Atlantic, each representing considerable extensions to their previously known biogeographical ranges. The shrimp genus Chicosciencea Bochini, Cunha, Terossi & Almeida, 2020, is confirmed as a junior synonym of Microprosthema Stimpson, 1860. Microprosthema pernambucensis (Bochini, Cunha, Terossi & Almeida, 2020), previously only known from northeastern Brazil, is reported for the first time from the tropical eastern Atlantic based on material collected in subtidal lava tubes on the coast of Sal, Cabo Verde, and re-illustrated in view of the limited original description.

Rangelands are dynamic ecosystems shaped by fluctuations in precipitation, temperature, and grazing intensity. Accurate assessment of forage availability is critical for optimizing land use, preventing overgrazing, and mitigating degradation, especially under future climate change scenarios. This study employed a multi-scale approach to monitor pasture using Sentinel-2 satellite imagery, calibrated with ground truth measurements, and enhanced with drone-derived vegetation cover estimates.

Due to Mediterranean climatic conditions, traditional pluvial agrosystems are widespread along the southern Mediterranean shore and were previously thought to have minimal impact on surface water resources due to low agricultural input levels. However, current pesticide applications are now considered to contribute significantly to the contamination of surface water resources, which may result in severe impacts on biodiversity and the environment. This study examined the presence and mobility risk of pesticides in the surface waters of the Lebna watershed in northeastern Tunisia, a rainfed Mediterranean agricultural region.
