Grassland soils are involved in the production of several ecosystem services, besides acting as important biodiversity reservoirs. In Iberian Peninsula, traditional management domestic livestock, including transhumance, has contributed to conservation semi-natural grasslands high ecological value. this context, drove roads, routes used for seasonal movements by transhumant shepherds search most productive pastures, play a key role. We evaluated how different states roads affect soil quality and fertility (C, N, K, P, pH, EC), well functioning (litter decomposition enzyme activity) within Madrid road network central Spain. For that, we established three categories: reference well-preserved two degraded states, overgrown abandoned eroded collected samples at each state. Our results showed that better preservation state its associated led greater activity. Eroded had significantly less nutrients lower litter rate than state, while activities where higher when compared both plots. confirmed hypothesis suffering from erosion have but same time, found processes some extent antagonistic, excessive accumulation biomass due grazing abandonment loss vegetation cover through erosion, lead similar functionality states. The lack use degradation threatens functions these natural corridors can support. Considering vast surface covered network, recovering be an tool.

Wetland ecosystems are essential to the global carbon cycle, and they contribute significantly storage regulation. While existing studies have explored individual effects of water depth, vegetation, soil properties on organic (SOC) components, a comprehensive study interactions between these factors is still lacking, particularly regarding their collective impact composition SOC in wetland soils. This paper focused Huixian Li River Basin.

Grassland soils, beyond their role as biodiversity reservoirs, actively contribute to the provision of numerous ecosystem services. In Iberian Peninsula, drove roads, traditional routes used for seasonal livestock movements in search most productive pastures, play a key preservation semi-natural grasslands and protection upper soil horizon. However, absence transhumant pastoralism has led degradation these natural corridors, with unexplored consequences terms quality functioning. To investigate relationship between conservation state characteristics, which had not been researched date, we selected thirty sites within Madrid road network central Spain. We established three categories: (i) reference well-preserved roads two degraded states: (ii) overgrown abandoned (iii) eroded collected samples at each state. determined physicochemical variables like percentage C, total N P, available K, pH electrical conductivity. also measured enzyme activity using fluorometric methods assessed litter decomposition through Tea Bag Index experiment. Our findings demonstrated that significant impact on fertility. The mean carbon was up ten times lower compared sites, while nitrogen content four higher phosphorus potassium were twice high sites.

The extensive use of antibiotics in the global livestock industry recent decades has accelerated accumulation and dissemination antibiotic-resistance genes (ARGs) within terrestrial ecosystems. This occurs due to limited absorption most antibiotics, leading their release into environment through feces urine. poses a significant threat both human health. However, response antibiotic-resistant microorganisms ARGs grasslands prolonged grazing, as well primary microbial taxa driving ARG distribution, remain poorly understood, especially various microhabitats. In this study, we characterized phyllosphere, litter, soil after grazing meadow steppe. We particularly focused on identifying major members community influencing distinction between generalists specialists. Our findings indicate that core set accounted for 90% abundance plant-soil ecosystem. While exhibited highest abundance, litter displayed higher diversity diverse distribution patterns overgrazing. Grazing increased by elevating proportion suppressing stochastic phyllosphere while it had little effect soil. Additionally, generalist increased, but specialist decreased with no soil, under grazed conditions. Ultimately, microhabitats influenced characteristics direct (i.e., other exogenous input) indirect trampling selective feeding) effects nutrient availability, composition, mobile genetic elements. community, its broad ecological niches phylogenetic made contribution characteristics. study underscores impact environmental disturbances distributional ecosystems, mediated regulation generalized species.
