The restoration of mangroves has gained prominence in recent decades. Hydrological rehabilitation been undertaken to connect impaired with the sea, lagoons or estuaries. Because mangrove hydrodynamics occurs on surface and interstitial spaces sediment, we propose determine hydrological flow paths restore regimes mangroves. were determined through a micro basin analysis based microtopographic data generate digital elevation model. Applying this methodological approach, hydrology an area...

Understanding the role of mangroves in microplastic (MPs) bioaccumulation is crucial to addressing pollution these ecosystems, particularly restored areas. Here, we 1) evaluate MPs plastic-biota-sediment accumulation factor (pBSAf) fiddler crab Minuca rapax and 2) describe type, colour, polymeric characteristics areas with varying restoration degradation levels Southern Gulf Mexico. We used regression models mangrove tree height, basal area, individuals' density explaining pBSAf. The highest...

Assessing water quality in aquifers has become increasingly important as demand and pollution concerns rise.In the Yucatan Peninsula, sinkholes, locally known cenotes, are karst formations that intercept table.Cenotes distributed across peninsula, but particularly dense aligned along a semicircular formation called Ring of Cenotes.This area exhibits particular hydrogeological properties because it concentrates, channels, discharges fresh toward coasts.In this study, we identify spatial...

Ecotoxicological tools, namely biomarkers and bioassays, may provide insights on the ecological quality status of mangroves under restoration. We investigated how 1) physicochemical parameters water bioassays using Artemia franciscana; 2) quantification sublethal (osmoregulatory capacity, biochemical, oxidative stress) individual (density, length-weight relationship [LWR], parasitic prevalence) in sentinel fiddler crab Minuca rapax, can improve restoration indicators from Yucatán Peninsula,...

Mangrove forests provide many ecosystem services, including the provision of habitat that supports avian biodiversity. However, hurricanes can knock down trees, alter hydrologic connectivity, and affect habitat. In 1995, Hurricanes Opal Roxanne destroyed approximately 1,700 ha mangrove forest in Laguna de Términos, Mexico. Since then, hydrological restoration has been implemented to protect its biodiversity.Since communities are often considered biological indicators quality, diversity...

We evaluated the success of ecological restoration a degraded mangrove forest by monitoring natural regeneration Avicennia germinans (black mangrove). The actions focused on hydrological rehabilitation desilting tidal channels and modifying microtopography to enhance or restore water flow. As result these efforts, population black established naturally. Six sampling sites including restored reference areas were established. measured seedling survival; tree density, height, growth rate;...

The hydroperiod determines the biogeochemical conditions and processes developing in mangrove soil. Floods control input of nutrients presence regulators such as salinity sulfides that, high concentrations, degrade vegetation. This work aimed to determine characteristics natural degraded conditions. Three sampling sites were placed along a spatial gradient, including fringe basin mangroves with different Tree variables (temperature, salinity, pH, redox potential, sulfides) measured....

Abstract The COVID-19 lockdown opened an opportunity to assess the response of animal populations diminished human activities. As coastal dunes face many disturbances caused by increasing activities, we assessed effect reduced mobility on bird diversity and abundance Least Tern nest failure rate island in southern Gulf Mexico before, during, after test hypothesis that tourism recreational activities can contribute conservation ecosystems species richness decreasing rate. We used data from...

Los manglares de Laguna Términos, Campeche han sido afectados por la pérdida conexión hidrológica durante el paso tormentas y huracanes. El objetivo este trabajo fue evaluar regeneración natural del manglar en un área degradada, después haber implementado acciones restauración hidrológica. Se establecieron tres sitios muestreo con diferentes tiempos (1 año - 3 años) sitio conservado como referencia. se realizó los años 2014 a 2015. evaluó densidad, altura, sobrevivencia tasa crecimiento las...

Mangroves are coastal wetlands with high biodiversity and productivity, great interaction environments. In the face of worldwide mangrove loss, restoration projects attempt to recover ecosystem composition functioning over time. Our objective was examine compare food webs in areas different times a reference Términos Lagoon, Mexico. We estimated trophic structure, identified carbon resources that maintain aquatic consumers through analysis stable isotopes, compared niche restored mangroves...

The Ring of Cenotes (RC) extends along the edge Chicxulub crater, in limestone platform Yucatan Peninsula (YP), where groundwater shows two preferential flow paths toward coast near Celestun and Dzilam Bravo towns. objectives this study were to describe regional hydrogeochemical evolution RC, its association with dissolution/precipitation minerals present pathway ocean. These results obtained by: (a) characterizing hydrogeochemistry; (b) calculating calcite, dolomite, gypsum saturation...

Antecedentes: Cambios en los patrones hidrológicos degradan la estructura forestal y afectan productividad primaria. Con acciones de restauración hidrológica, se pretende restablecer condiciones biogeoquímicas para facilitar el establecimiento, sobrevivencia crecimiento vegetación del manglar que permitan recuperación raíces subterráneas (< 20 mm).Pregunta: ¿Pueden cambios ambientales inducidos por hidrológica reactivar raíces?Especie estudio: Los biomasa Avicennia germinans fueron usadas...

Las carreteras representan un vínculo entre el desarrollo social y económico. Sin embargo, también barreras que fragmentan hábitat e impactan la dinámica natural de los ecosistemas su fauna silvestre. En México, estudios acerca del efecto las sobre silvestre son escasos, se desconoce número especies animales mueren en ellas. El propósito este trabajo es contribuir al conocimiento impacto tienen silvestre, averiguando cuáles grupos taxonómicos con mayor frecuencia atropellamientos cuál tasa...
