Observations of Litter Deposited in the Deep Waters of Isla del Coco National Park, Eastern Tropical Pacific

open access: yesFrontiers in Marine Science, 2018
Marine debris is recognized as a major threat to biodiversity and can be found ubiquitously even in remote regions, including deep-sea environments. Isla del Coco National Park is known as one of the best protected areas around the world, a preferred ...

Machine and deep learning approaches to understand and predict habitat suitability for seabird breeding. [PDF]

open access: yesEcol Evol, 2023
Understanding seabird breeding habitat selection and suitability is often complex due to the integration of land and sea features across multiple spatial scales. A complementarity approach between convolutional neural network (CNN) and random forest (RF) models was applied to predict and explain the selection pattern of tropical larids breeding ...

Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

Co‐acquisition of mineral‐bound iron and phosphorus by natural Trichodesmium colonies

open access: yesLimnology and Oceanography, Volume 68, Issue 5, Page 1064-1077, May 2023., 2023
Abstract Low iron (Fe) and phosphorus (P) ocean regions are often home to the globally important N2‐fixing cyanobacterium Trichodesmium spp., which are physiologically adapted to Fe/P co‐limitation. Given Trichodesmium's eminent ability to capture particles and the common associations between Fe and P in sediments and aerosols, we hypothesized that ...

Genetic population dynamics of the critically endangered scalloped hammerhead shark (Sphyrna lewini) in the Eastern Tropical Pacific

open access: yesEcology and Evolution, Volume 12, Issue 12, December 2022., 2022
The scalloped hammerhead shark is a Critically Endangered (IUCN Red List), circumglobally distributed species in warm temperate and tropical seas. This species exhibits both periods of restricted movements as well a strong migratory propensity and is known to form iconic, large seasonal aggregations at offshore oceanic islands.

Rare coral and reef fish species status, possible extinctions, and associated environmental perceptions in Mauritius

open access: yesConservation Science and Practice, Volume 3, Issue 11, November 2021., 2021
Abstract Mauritius is reported to have the highest marine species endemism in the Western Indian Ocean faunal Province but the status of these species has not been evaluated. To address this knowledge gap, 119 reef sites were sampled to evaluate populations of 16 species of rare and endemic reef fish and corals using scuba‐based surveys conducted by ...

Using very‐high‐resolution satellite imagery and deep learning to detect and count African elephants in heterogeneous landscapes

open access: yesRemote Sensing in Ecology and Conservation, Volume 7, Issue 3, Page 369-381, September 2021., 2021
In this study, we apply a Convolution Neural Network (CNN) model to automatically detect and count African elephants in a woodland savanna ecosystem in South Africa. We use WorldView‐3 and 4 satellite data – the highest resolution satellite imagery commercially available.
