Habitat-dependent occupancy and movement in a migrant songbird highlights the importance of mangroves and forested lagoons in Panama and Colombia. [PDF]

Ecol Evol, 2019
We found that overwintering occupancy and movement are habitat‐dependent in a nonterritorial overwintering migrant bird. Warblers in mangroves and other wet habitats are least likely to experience local extinction as dry season progresses, and warbler abundance was highest in mature mangroves forests.

Is the threatened land crab Cardisoma guanhumi conquering human-dominated systems? [PDF]

Ecol Evol
Land use change has been recognized as a major contributor to habitat destruction, the main cause of biodiversity loss. However, recent findings show that cities – probably the most radical habitat transformation – may sustain threatened species. This intriguing trend has been mostly chronicled in small‐scale studies of vertebrate communities from ...

Changes in mercury content in oysters in relation to sediment and seston content in the Colombian Caribbean lagoons [PDF]

PeerJ
Total mercury (Hg) was evaluated in the mangrove oyster Crassostrea rhizophorae, in sediments and seston from the Ciénaga Grande de Santa Marta (CGSM) and Cispatá Bay (BhC) in two climatic seasons (rainy and dry).

Biodiversidad exótica: presencia de especies marinas no-nativas introducidas por el tráfico marítimo en puertos colombianos

Biota Colombiana, 2011
Colombia's favorable geographic location between the Caribbean Sea and the Pacific Ocean combined with the high shipping activity of its ports (nearly 30000 arrivals per year) make it susceptible to the introduction of non-native marine species. In light

Population ecology of the spectacled caiman (Caiman crocodilus) in the Apaporis River middle basin

Ecosphere, Volume 12, Issue 5, May 2021., 2021
Abstract Population ecology studies on spectacled caimans (Caiman crocodilus) in Colombia have been few and far between with many covering short periods and defining population parameters based on relative indices (i.e., individuals/km). This reflects a lack of information on the general effects that environmental variables have on annual cycles of ...

Human–crocodilian interactions in Latin America and the Caribbean region

Conservation Science and Practice, Volume 3, Issue 5, May 2021., 2021
Abstract Mitigating harmful interactions with wildlife requires an understanding of the interactions between predators, domesticated animals and humans. Large‐scale transformations of crocodilian habitats across the Latin America and Caribbean region, alongside significant use of crocodilians as a resource, and retaliatory killing of crocodilians ...

Sand addition promotes gharial nesting in a regulated river‐reservoir habitat

Ecological Solutions and Evidence, Volume 2, Issue 2, April–June 2021., 2021
Gharial nesting and successful hatching is dependent upon open nesting banks, free of vegetation. In a river‐reservoir with increased bankside vegetation, due to reduced water flow, the construction of open nesting banks by sand addition resulted in increased nesting and hatching, when compared to removal of vegetated sandbanks.

Cispatá Bay and Mestizos Evolution as Reconstructed from Old Documents and Maps (16th–20th Century)

Journal of Marine Science and Engineering, 2020
Historical cartography is increasingly being used for the study of coastal evolution, but less considered are coeval descriptive sources as well as exploration reports that accompany the construction of maps.
