1. Geospatial analysis of the effects of tsunami on coral and mangrove ecosystems of Mayabunder in Andaman Islands, India
Abstract Mangroves and coral reefs are among the major ecosystems of tropical and subtropical coastlines. The Andaman group of islands, situated at the juncture of Bay of Bengal and Indian Ocean, are one of the richest coastal ecosystems of India in terms of biodiversity. Since the tsunami waves of 2004 affected this region severely, the outer fringes as wel

2. Morphological description and new records of Hygrocybe conica var. conica and H. nigrescens var. brevispora (Hygrophoraceae) in Brazil
RESUMO Hygrocybe conica var. conica e H. nigrescens var. brevispora foram coletados em floresta de Mata Atlântica, respectivamente nos Estados do Paraná e do Rio Grande do Norte. Esses dois táxons foram reportados em listas de diversidade de macrofungos no Brasil; entretanto suas características morfológicas e variações foram, até então, pouco docum

3. Vulnerability of ecosystems with Guadua angustifolia in Ecuador in light of climate changes1
RESUMO O bambu Guadua angustifolia é historicamente utilizado por porcentagem significativa da população rural e periurbana do Equador, em especial na construção de pontes, quando ocorrem inundações resultantes de fenômenos como o El Niño. Objetivou-se determinar, em face de alguns cenários de mudanças climáticas, o índice de vulnerabilidade de

4. Organic matter composition related to methane ebullitive flux of an urban coastal lagoon, Southeastern Brazil
In 2016, Brazil emitted 18.25 Tg of methane. Some of these emissions occur through continental aquatic ecosystems, locations of fate and accumulation of organic and inorganic matter. Thus, the aim of this study is to evaluate the origin of organic matter in Rodrigo de Freitas Lagoon, an eutrophic, coastal and chocked lagoon in Rio de Janeiro, Brazil, through

5. Crane flies (Diptera, Tipuloidea) from southern Neotropical salt marshes: survey with DNA barcoding
ABSTRACT Crane flies are the most diverse group within Diptera, but they are rarely studied in coastal ecosystems. Considering the scarcity of information on the biology and ecology of this group in the Neotropics, and the sparse literature available for taxonomic identification, we developed a descriptive checklist that incorporates morphology and DNA barco

6. Lizard assemblages on sandy coastal plains in southeastern Brazil: An analysis of occurrence and composition, and the role of habitat structure
Abstract Data on the structure of lizard communities in the different biomes and ecosystems of Brazil are still limited. In this study, we related the species richness, abundance and the spatial occurrence of lizards to the structure of the vegetation found on the coast of the state of Espírito Santo, southeastern Brazil, to determine whether habitat influe

7. Bird diversity and conservation in the southern coast of Santa Catarina state, Brazil
Abstract Coastal lagoons and their surrounding habitats often harbour high biodiversity and some of the most threatened ecosystems in the world. However, in the Neotropics the biodiversity is often poorly described, lacking even inventories of species which therefore limits the assessment of threats and the stablishment of efficient conservation measures. We

8. Morphometric and molecular differences among Calvertius tuberosus (Coleoptera: Curculionidae) populations associated with Andean and coastal populations of Araucaria araucana in the La Araucanía Region, Chile
Abstract Calvertius tuberosus (Curculionidae) lives exclusively on Araucaria araucana trees (commonly known as pehuen) in southern Chile. In this study, morphometric and molecular genetic analyses of Andean and coastal populations of C. tuberosus were performed to evaluate evolutionary divergence associated with the discontinuity of the Araucaria forest betw

9. Disentangling plant establishment in sandy coastal systems: biotic and abiotic factors that determine Allagoptera arenaria (Arecaceae) germination
ABSTRACT Germination rate and establishment success of plants in harsh environments depend on the ability of seeds to withstand unfavorable environmental conditions and avoid predators. Brazilian coastal plains, known as restinga, are subject to environmental factors that seriously limit plant establishment and survival (e.g. salinity, desiccation, oligotrop

10. Reporte y distribución potencial de una palma exótica ornamental (Roystonea oleracea) en Ecuador
Abstract The Roystonea oleracea palm, a native of the Caribbean, has been introduced in some tropical countries as an ornamental plant and it invades the wetlands of Brazil, Guyana and Panama. In this study we report the presence of R. oleracea in the coastal region of Ecuador where it is widely cultivated as an ornamental. Using a satellite image, we estima

11. Molecular detection of flaviviruses and alphaviruses in mosquitoes (Diptera: Culicidae) from coastal ecosystems in the Colombian Caribbean
Arboviruses belonging to the genera Flavivirus and Alphavirus were detected in mosquitoes in a rural area of San Bernardo del Viento (Córdoba, Colombia). A total of 22,180 mosquitoes were collected, sorted into 2,102 pools, and tested by generic/nested reverse transcription-polymerase chain reaction.

12. Review of thirty-two years of toothed whale strandings in Santa Catarina, southern Brazil (Cetacea: Odontoceti)
ABSTRACT Marine mammal strandings provide valuable insights into local biodiversity. Strandings can be caused by both natural and anthropogenic factors. In the state of Santa Catarina, Southern Brazil, organized marine mammal collections started in the 1980s through opportunistic and non-systematic collection efforts, representing a record of over 30 years o
