“…The spatial structure of forested terrain is listed as an important indicator for monitoring carbon stocks by the International Union of Forest Research Organizations (IUFRO) [1,2]. Assessing ground topography in forested terrain is a prerequisite to accurately determine the forest spatial structure; therefore, high spatial resolution modeling is necessary to characterize forest ecosystems [3,4].…”

As a continuation of Ice, Cloud, and Land Elevation Satellite-1 (ICESat-1), the ICESat-2/Advanced Topographic Laser Altimeter System (ATLAS) employs a micro-pulse multi-beam photon counting approach to produce photon data for measuring global terrain. Few studies have assessed the accuracy of different ATLAS channels in retrieving ground topography in forested terrain. This study aims to assess the accuracy of measuring ground topography in forested terrain using different ATLAS channels and the correlation between laser intensity parameters, laser pointing angle parameters, and elevation error. The accuracy of ground topography measured by the ATLAS footprints is evaluated by comparing the derived Digital Terrain Model (DTM) from the ATL03 (Global Geolocated Photon Data) and ATL08 (Land and Vegetation Height) products with that from the airborne Light Detection And Ranging (LiDAR). Results show that the ATLAS product performed well in the study area at all laser intensities and laser pointing angles, and correlations were found between the ATLAS DTM and airborne LiDAR DTM (coefficient of determination––R2 = 1.00, root mean squared error––RMSE = 0.75 m). Considering different laser intensities, there is a significant correlation between the tx_pulse_energy parameter and elevation error. With different laser pointing angles, there is no significant correlation between the tx_pulse_skew_est, tx_pulse_width_lower, tx_pulse_width_upper parameters and the elevation error.

“…Experiments in north-eastern Brazil showed high Rhizophora mangle propagule survival (70-90%) in densely reforested areas with preserved soil and hydrological conditions (Ferreira et al, 2015). The aboveground biomass stock of this forest was higher than in naturally recovered stands after 5 years of planting, and after 10 years the biomass of this forest was similar to the biomass of nearby 40-year-old forest fragments (Ferreira, Bezerra, & Mathews-Cascon, 2019). This shows that planted monospecific stands of R. mangle can have good survival outcomes and rapid development (Menezes et al, 2005;Ross et al, 2001;Rovai, 2012) and can restore several ecological functions (such as productivity, carbon sequestration, and cycling) and the return of key functional groups (such as the fossorial brachyuran crabs:…”

Data also suggest that some brachyurans, through consumption of more propagules of lower biomass stock trees, such as Laguncularia racemosa , can favour the predominance of R. mangle , reinforcing higher aboveground carbon storage in the forest (Ferreira et al, ).…”

This study assesses the evolution of major anthropogenic drivers of environmental impacts on Neotropical mangroves, the changes in the environmental pressures acting upon them, and the respective societal responses during the past 40 years. It reviews the impacts of new drivers, in particular those resulting from global climate change and the expansion in aquaculture and the effectiveness of local societal responses aimed at addressing them. Adaptation and mitigation actions are proposed to cope with the impacts and their socio‐economic consequences for Latin America and Caribbean mangroves. By comparing the situation in Latin America and the Caribbean with other regions, the knowledge gaps and priority research needs are discussed to support delineating a preliminary unifying framework to address the environmental pressures affecting mangroves. This scenario necessarily includes the interaction of climate change with human interventions and their effects on ecosystem goods and services, as well as their respective adaptation and management options. Results show that drivers of environmental impacts have changed in the past 40 years, reducing the effectiveness of some important societal responses towards conservation and sustainable management with a great potential to increase rates of mangrove deforestation and conversion to human uses. Although efforts in conservation and restoration have contributed to decreasing pressure on these ecosystems, the coupling of old drivers, such as damming, with climate change, and the appearance of new drivers in the region, such as shrimp aquaculture, may eclipse the gains made through these conservation efforts. Despite the negative trend, we discuss some successful efforts to curb negative impacts of human activities on mangroves. We also recommend regional assessments based on primary sources in the representative mangrove‐bearing countries throughout the continent to allow the upscaling of their experiences towards a regional response to the challenges facing Neotropical mangrove conservation and sustainable use.

“…More penetrable sediments with higher organic matter content favor the establishment of a higher diversity of brachyurans in Pacoti River. Established brachyuran species can mediate forest composition by high differential propagule consumption and/or burial (Ferreira et al 2013(Ferreira et al , 2019. When forest composition is dominated by Rhizophora, prop root structure allows construction of rich multi-specific brachyuran interconnected systems of burrows, proper of Neotropical mangroves.…”

Biotic factors include tree architecture (with tree species determined by competition for light and seed herbivory, among others), soil bioturbation and plant-soil interactions driven by sediment microbiota, most notably by benthic fauna engineering (Warren and Underwood 1986, Lee 1999, Minchinton 2001, Cannicci et al 2008, Ferreira et al 2013, 2019.…”

Mangroves are dynamic ecosystems due to influence of abiotic and biotic factors, but the latter are far less studied. Interactions between key invertebrate groups, trees, and soil properties, among others, determine the community structure throughout mangrove stand developing. Covariation among these factors, however, obscures their mutual relationships in shaping mangrove community assemblage patterns. In the estuary of Pacoti River (Ceará State, northeast Brazil), we compared the diversity and distribution of brachyurans and trees among several mid-littoral areas, and their relation with sediment features, to understand their relationships in community assemblage of new mangrove stands in developing. To discriminate the relation among these variables, ordination of data (PCA) and multivariate multiple correlation (PLS) were used. Data show that intertidal establishment of Brachyura was determined primarily by sediment properties, but further spatial distribution and diversity of this key faunal group, and the tree species that establishes, can influence each other. The prop roots habitat of Rhizophora mangle supports a higher brachyuran richness, since it allows the existence of multispecific crab burrow systems underground. Our results show that Rhizophora and brachyurans are key engineer organisms involved in shaping the physical and, hence, the ecological structure of newly established mangrove stands at Neotropics.
