“…En éstos se observan parches remanentes de vegetación original y colindan principalmente con los tulares. Tienen la mayor riqueza y diversidad de los humedales de estudio y también con respecto a los pastizales inundables de Veracruz estudiados por Travieso-Bello, Moreno-Casasola y Campos (2005) y Rodríguez-Medina et al (2017). Es una comunidad de herbáceas, dominada por el pasto nativo P. conjugatum, especie frecuente en sitios inundados.…”

Introduction: The characteristics of coastal wetlands are the result of hydrogeomorphological interactions between the continent and the ocean, which cause an environmental gradient, hat results in different vegetation types such as mangroves, freshwater marshes, swamp forests and palm swamps. Objective: To characterize the hydroperiod and physicochemical variables of water and soil and their effect on the distribution of vegetation in the Sistema de Humedales El Castaño. Methods: A total of 11 permanent sampling units (UM) were established by defined strata: five in the mangrove, two in swamp forest, two in freshwater marshes and two in the flooded pasture. From May 2016 to October 2017 the vegetation was characterized and the water levels and physicochemical parameters (superficial, interstitial and groundwater) were sampled monthly for: salinity, and pH; and the soil for: bulk density, humidity percentage, and redox potential. Results: Mangroves are the closest to the sea, have the lowest diversity (H: 1.66) and species richness (14), they are dominated by Laguncularia racemosa and Rhizophora mangle, have the highest values of interstitial and groundwater salinity, (> 10.8 ups), remain flooded for 4 to 12 months per year, and have a redox potential of 14.57 mV. Immediately, inland, there are remnants of the swamp forests (H: 2.18 and 18 species), dominated by Pachira aquatica, with 5 ups interstitial and groundwater salinity, flooded from 0 to 6 months per year, with a redox potential of 119.07 mV. These forests are followed inland by freshwater marshes (H: 1.92 and 16 species), dominated by Typha domingensis with 6.1 ups interstitial and groundwater salinity, flooded for 5 to 8 months per year and a redox potential of 125.9 mV. Finally, furthest inland is the flooded pasture, a modified herbaceous wetland for cattle grazing (H: 3.44 and 50 species) dominated by Paspalum conjugatum, where interstitial and groundwater salinity is less than 0.5 ups, it stays flooded for 5 to 9 months and the redox potential is 151.23 mV. Conclusions: In each type of vegetation, the structure, composition, and diversity are different, with a high turnover of species that indicates a gradient defined by salinity. The vegetation in the SHC follows the patterns of typical organization of the tropical coastal wetlands, mangroves, swamp forests and herbaceous wetlands, in this case the freshwater marshes and flooded pastures. The factor that define the distribution of the vegetation is the salinity and the gradient that is observed are a function of the hydrological dynamics that depends on the mixing of marine and freshwater.

“…On the one hand, cattle production and exports contribute to the livelihoods of poor families in the region, as well as to the overall economy of the countries (FAO, 2019). As noted by Rodríguez et al (2016), the strengthening of the sector has generated job opportunities and income throughout the production chains, including processors, transporters, retailers, exporters, and related industries. Food security is another of its major contributions, since moderate meat consumption provides important macro and micronutrients for humans, such as proteins, fats, vitamins B and D, iron, and zinc (Scollan et al, 2017;Cocking et al, 2020).…”

“…Despite these aspects, cattle production in LAC has negative impacts on the environment, such as on soil degradation (Mora et al, 2017), destruction of wetlands (Rodríguez et al, 2017), deforestation (Armenteras and Rodríguez, 2014), GHG emissions (Molina et al, 2019), and loss of biodiversity (Marques et al, 2019), to which the challenge of providing animal welfare conditions is added (Muñoz, 2014). According to Calle et al (2012), the development of the sector has caused the loss of forests, in addition to favoring practices based on pasture monocultures that contribute to climate change.…”

Scientific research is increasingly conclusive regarding the responsibility of food production in environmental issues, a situation that contrasts with greater consumer awareness. In this context, sustainability labels for meat have emerged, which offer a guarantee that production is based on principles of animal welfare, and carbon neutrality, among others. Since research on this subject is scarce, the objective of this article is to identify and analyze the initiatives and development of this type of labeling in Latin America and the Caribbean. For this purpose, a qualitative-descriptive study is carried out based on primary and secondary sources. The results show different types of progress in the main producing countries, with Uruguay and Brazil standing out as success stories. At the same time, difficulties are highlighted in the different stages of the production chain, such as low demand, or traceability. It is concluded that, despite the challenges, the transition to sustainable cattle farming is inevitable. However, this process will not happen spontaneously, but must be coordinated up with other types of strategies and the actions of various actors including governments, policymakers, and NGOs.

“…With the introduction of cattle, trampling is a common problem that causes soil compaction by decreasing its porosity and increasing the apparent density, affecting the growth and establishment of native plants (Crush & Thom 2011; Morris & Reich 2013). In addition, introducing exotic grasses decreases resources and changes the physicochemical variables of water and soil (Zedler & Kercher 2004; Travieso‐Bello et al 2005; Rodríguez‐Medina et al 2017; López‐Rosas et al 2019; Ren et al 2021).…”

The expansion of cattle ranching in the coastal plain of the Gulf of Mexico is transforming freshwater swamps resulting in the reduction of swamps area and the introduction of invasive exotic grasses. This study seeks to determine the structure of the remaining population of Annona glabra in a grassland, evaluate vegetation and environmental conditions of the grassland, and determine the germination capability of A. glabra under different cover conditions of grass growth and two flood levels. The study area is a flooded grassland invaded by Echinochloa pyramidalis in central Veracruz, Gulf of Mexico. In the grassland, we censused and mapped the remaining individuals of A. glabra. We sampled the vegetation and measured the physicochemical characteristics of the soil and water. To evaluate the effect of the invasive grass on the germination of A. glabra seeds, we designed two greenhouse experiments: one (E1) under soil moisture at field capacity and another (E2) under flooded conditions. We found 312 remnant individuals. We recorded 31 plant species, most (72.7%) classified as aquatic/semiaquatic. The relative importance value was highest for E. pyramidalis, Mimosa pigra, and Eleocharis mutata. BEST analysis did not detect significant correlations between vegetation and physicochemical variables, indicating homogeneous environmental conditions. Seed germination was above 80% in E1 and below 20% in E2 in all grass cover levels. Although flooding decreases germination rates, substantial proportion of seeds can germinate, suggesting that natural succession is viable. Based on our results, the flooded grassland has conditions to restore swamp.
