An emerging coastal wetland management dilemma between mangrove expansion and shorebird conservation. [PDF]

Conserv Biol, 2022
Abstract Coastal wetlands around the world have been degraded by human activities. Global declines in the extent of important coastal wetlands, including mangroves, salt marshes, and tidal flats, necessitate mitigation and restoration efforts. However, some well‐meaning management actions, particularly mangrove afforestation, can inadvertently cause ...

Urban-Wild Interface Diversity: A Comprehensive Checklist of Herpetofauna of Guayaquil, Ecuador. [PDF]

Ecol Evol
Amphibians and reptiles in Guayaquil comprise multiple taxonomic orders and occur across conservation areas, forest remnants, and urban parks, including several endemic species and numerous taxa with type localities in the city. Although most species are globally classified as Least Concern, discrepancies between global and national threat assessments ...

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots. [PDF]

Conserv Biol
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Unraveling the genomic landscape of Campylorhynchus wrens along western Ecuador's precipitation gradient: Insights into hybridization, isolation by distance, and isolation by the environment. [PDF]

Ecol Evol
Environmental gradients influence genetic differentiation and can lead to allopatric speciation or hybridization, as investigated in a hybrid zone involving two wren species in western Ecuador. Our study utilized 4409 SNPs from 112 blood samples, revealing evidence of genetic structure and admixture influenced by geographical and environmental factors.

Global drivers of mangrove loss in protected areas. [PDF]

Conserv Biol
Abstract Despite increasing efforts and investment in mangrove conservation, mangrove cover continues to decline globally. The extent to which protected area (PA) management effectively prevents mangrove loss globally across differing management objectives and governance types is not well understood.

Blue Carbon Stocks Along the Pacific Coast of North America Are Mainly Driven by Local Rather Than Regional Factors. [PDF]

Global Biogeochem Cycles
Abstract Coastal wetlands, including seagrass meadows, emergent marshes, mangroves, and temperate tidal swamps, can efficiently sequester and store large quantities of sediment organic carbon (SOC). However, SOC stocks may vary by ecosystem type and along environmental or climate gradients at different scales.

Combining otolith chemistry and genetics to infer the population structure of yellow snapper Lutjanus argentiventris

Ecosphere, Volume 14, Issue 10, October 2023., 2023
Abstract Developing a metapopulation framework contributes to the understanding of spatial processes and structures in populations, providing basic information for conservation biology. However, the extent to which the metapopulation structure differs geographically and across life history stages is unexplored for most fishes.

Holocene Marine Tephra Offshore Ecuador and Southern Colombia: First Trench‐to‐Arc Correlations and Implication for Magnitude of Major Eruptions

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 9, September 2022., 2022
Abstract Tephra layers preserved in marine sediments are strong tools to study the frequency, magnitude and source of past major explosive eruptions. Thirty‐seven volcanoes from the Ecuadorian and Colombian arc, in the northern Andes, experienced at least one eruption during the Holocene.

Roadkill patterns in Latin American birds and mammals

Global Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022
Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

Litter‐trapping tank bromeliads in five different forests: Carbon and nutrient pools and fluxes

Biotropica, Volume 54, Issue 1, Page 170-180, January 2022., 2022
Bromeliads are the most abundant litter‐trapping plants in Neotropical forest canopies. We analyzed the carbon and nutrient pools and fluxes in tank bromeliads in different forests along an elevation gradient. Only a small percentage of the annual litterfall (<3%) is trapped by tank bromeliads.
