Grasslands cover more than 25% of the Earth’s surface and play essential ecological roles, such as forage production, supporting pollinators, and carbon sequestration. This study aimed to evaluate the recovery of a degraded pasture of Urochloa decumbens cv. Basilisk through aerial dry mass production, plant height, and foliar macronutrients concentration and uptake after fertilization with polyhalite. The experiment was carried out at the Teaching, Research, and Extension Farm of the School of Agrarian and Technological Sciences, UNESP—Dracena Campus, in a dystrophic red–yellow latosol soil. A randomized block design with four replications was used. The treatments included the following: (T1) control, (T2) N + P + liming, (T3) T2 + 30 kg ha⁻¹ K₂O (polyhalite), (T4) T2 + 60 kg ha⁻¹ K₂O (polyhalite), (T5) T2 + 60 (30 + 30) kg ha⁻¹ K₂O (polyhalite), and (T6) 60 kg ha⁻¹ K₂O (polyhalite). The treatment with N + P + liming + 60 kg ha⁻¹ K₂O (polyhalite) resulted in 93% more dry mass production when compared with the control treatment. This treatment was most effective for grassland recovery, whereas polyhalite alone was ineffective. Tissue N and S concentrations increased as a result of the addition of N + P + liming + 60 kg ha⁻¹ K₂O (polyhalite).

Amphibians are the first tetrapodes (gr. tetra, four + prunes, foot) vertebrates conquering the terrestrial environment, are important predators of insects and other invertebrates. Considered opportunistic with regard to feeding habits, and the diet of a given species may reflect in part the availability of prey in the habitat. The present work deals with the niche overlap between the species Leptodactylus chaquensis and Leptodactylus podicipinus based on field collections in the municipality of Cuiabá, Mato Grosso.

With the increase in demand for food, agricultural activity began to be characterized by standardized monoculture systems and began to be carried out in an intensified manner, however, due to the high demand for natural resources, it has been presenting itself with low environmental sustainability.
