There is a need to develop indicators of mangrove condition using remotely sensed data. However, remote estimation leaf and canopy biochemical properties vegetation remains challenging. In this paper, we (i) tested the performance selected hyperspectral broad band indices predict chlorophyll concentration (CC) on leaves (ii) showed potential Landsat 8 for CC at landscape level. Relative spectral response were measured 12 Elementary Sampling Units (ESU) distributed along northwest coast...
Summary In light of the continuing biodiversity crisis, need for high‐resolution, broad‐scale ecological data is particularly acute. The expansive scale volunteer collection programmes provides an opportunity to address this challenge, however, protocols used collect such are typically less standardized than those by professional scientists. Although previous studies have established that different can lead results, it remains unclear how relevant these differences specific study goals, as...
Understanding the structural complexity of coral reefs is essential for assessing their condition, biodiversity, and resilience. Traditional methods commonly use a rugosity index, based on chain method, that overlooks underlaying structure reefs. However, digital underwater photogrammetry allows to build models structures which can then be used decompose reef topography across multiple layers. This study introduces wavelet-based method multiscale analysis rugosity, considering reef’s surface...
Sea urchins perform key ecological functions in coral reefs, such as herbivory and erosion of calcareous structures, which intensify at night. The Cayo Arenas reef, Campeche Bank, Mexico, is located far from the coast, has helped to protect it direct anthropogenic threats. However, no information available on status sea urchin populations bioerosion processes they reef. For this reason, we conducted diurnal nocturnal surveys characterize density a function diel cycle calculate their...
The Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), is an invasive species and a vector of numerous human pathogens, including chikungunya, dengue, yellow fever, Zika viruses. This mosquito had been reported from 36 geographic locations in Mexico by 2005, increasing to 101 2010 501 (spanning 16 states) 2016. Here we modeled the occupied niche for Ae. characterize environmental conditions related its presence, generate updated suitability maps. predictors with greatest...
The characterisation of changes in coral communities depends heavily on systematic monitoring programs and the collection necessary metrics to assess reef health. Coral cover is most used metric determine current organizational shift requires evaluation complementary metrics, such as colony size frequency distributions, which help infer responses populations local stress or larger scale environmental changes. In this study, underwater digital photogrammetry techniques were live all colonies...
Abstract Mangrove forests provide important ecosystem services that support the maintenance of coastal socio-ecological systems. Strategies such as establishment Natural Protected Areas (NPAs) have been encouraged worldwide to promote their conservation. However, mangroves are still being lost a consequence anthropogenic disturbance and environmental variation. In here, we determine change rate in mangrove cover, between 2005–2015, eight NPAs corresponding four km adjacent transition area...
Abstract Natural protected areas (NPAs) in the Yucatan Peninsula favour conservation of mangrove forests, which are valuable ecosystems for their provision ecosystem services. However, mangroves vulnerable to destruction due natural and anthropogenic pressures. Therefore, it is important assess spatial temporal dynamics potential deforestation recovery cover. In this study, we analyse model forest cover change six NPAs by 2025. Predictions were made using cellular automata method (CA-Markov)...
Bahía Concepción was once recognized as a very productive coastal lagoon not only for the Peninsula of Baja California but also all Mexico. However, lack proper management has resulted in closure various fisheries, such Calico scallop, Argopecten ventricosus, 1994. One main challenges resources is selection critical habitats conservation considering economic activities communities associated with them. This study used Geographic Information Systems (GIS) and remote sensing to assess roll...
The ecosystem services (ESs) approach has been used as a powerful tool for the analysis of socio-ecological systems to investigate relationship between society and environment. aim this article is analyze social perceptions stakeholders, forms use (sociocultural economic), conservation beaches coastal dunes in Yucatán, Mexico. Interviews were held with focus groups use, results indicate that these ecosystems are important different types activities related regulating, provisioning, cultural...
The precise assessing and monitoring of coral reefs are necessary to address understand the threats changes in communities. With development new technologies algorithms for image processing, protocols like underwater photogrammetry implemented study these ecosystems. This compares main ecological metrics reef condition assessment, obtained with an digital protocol (UWP) traditional sampling design simulations Cozumel Reefs National Park. Three orthomosaics (380 m 2 ) per on six fringing were...
We modeled the ecological niche of Yucatan Rattlesnake (Crotalus tzabcan) to map its environmental suitability, estimate potential distribution, and identify factors that limit geographic range within Peninsula (YP). Niche models were built evaluate, separately together, ability different sets predictors explain distribution this species. The relative contribution percentage from each variable was calculated with better predictive ability. Response curves also constructed observe influence...
The effects of Hurricane Emily (July 2005, Category 4) on nine different benthic substrates in the reef-associated landscape along west coast Cozumel (Mexico) were evaluated by comparing cover types substrate ground-truthed sites before (ten months) and after (two hurricane. Four showed significant differences (Wilcoxon signed-rank test, P < 0.05). Coverage sand over rock increased, while that seagrass hard corals decreased. hurricane soft diminished below 10 m depth. Sites between 0.5...
Beach width, dune height, and vegetation coverage are key parameters to assess beach resistance resilience storms. However, coastal development often causes ecosystem degradation due poor management. We propose a Coastal Resilience Index from Remote Sensors (CRIfRS) for urbanized coasts based on aerial photogrammetry. The study area, located along 7.8 km stretch of coast barrier island, is characterized by persistent alongshore sediment transport the presence structures beach-front houses....
