“…Anthropogenic impacts modify geomorphological and hydrodynamic processes and ecosystems and change the forms of resources, including biological resources. This finding is consistent with the Amstrong study on Chrismas Island and Cocos Island (Armstrong P., 1992). Study results from the Nam Yet Island region address the difficulty and challenge of quantifying the benthic habitat in marine landscape mapping due to spatial variations and more significant depths (over 40 m, which is restricted for novice divers).…”

Classification and mapping of marine-island landscapes according to an integrated approach not only clarifies the structure and division of natural units of the sea areas but also creates a basis for the orientation of natural resource management resources, environmental protection, and conservation of marine-island biodiversity. The principles of marine-island landscape mapping are to define terminology and establish a classification system based on taxonomy and criteria. This article represents the establishment of marine-island landscape mapping of Nam Yet Island and adjacent water (scaled at 1:10000) through comprehensive work, including marine-island landscape classification, applied GIS - remote sensing, and field investigation in the two years of 2020-2021. Accordingly, the landscape classification system of the Nam Yet Island area includes 1 system, 1 subsystem, 4 classes, 6 subclasses, 10 types, 29 kinds, and 34 forms of landscape (of which 4 island forms and 30 marine forms). The units of the marine-island landscape fully express the natural components, anthropogenic factors, and biotic and abiotic factors in their relationship and interaction with each other. Depending on each corresponding level, the detailed level of components and landscape elements is shown, in which components and biological factors are studied and analyzed most fully. The research results have clarified the characteristics and the law of differentiation of the marine-island landscape in Nam Yet Island, contributing to supplementing knowledge about Truong Sa Islands of Vietnam, which is a scientific basis for resource management and biodiversity conservation, protecting the marine environment, and at the same time supplementing the theoretical basis for the study of the tropical monsoon tropical island and marine landscape, which has not yet been studied in Vietnam.

“…As the de‐extinction method of choice for the rat would most likely be via genome editing of the brown rat ( Rattus norvegicus ), it is possible that this could be achieved by maintaining some of the immune genes of this species rather than replacing with those of the Christmas Island rat. The brown rat has established itself on Christmas Island (Armstrong ) so it appears that it is equipped with the required immunity for survival here. If the brown rat is used as a surrogate, the individual should also obtain antibodies for resistance during gestation.…”

The potential and pitfalls of de‐extinction

2016

‘De‐extinction’ is the nascent discipline that aims to one day literally revive now‐extinct species from the dead. Although we have yet to see any successful attempts to truly resurrect an extinct species, several technologies are now in place that might one day provide a plausible solution. Thus, the area is receiving increased attention from both scientists and the general public. However, how far does present technology place us from the ultimate goal? We address the state of the art of several prominent de‐extinction methods: back‐breeding, cloning, synthetic genomics and genome editing, and discuss some of the major outstanding challenges for each. We also discuss some of the wider challenges facing de‐extinction, including both what might constitute the definition of success and what might be needed to successfully take a recreated animal and confer on it the ability to establish itself back in the wild.

“…However, the reduction or loss of breeding colonies of birds from many of the Chagos islands due to rat infestation will lead to reduced inputs of phosphorus and nitrogen (cf. Armstrong, 1992) which will ultimately affect the capacity of some cryptogamic plants to establish themselves on soils inherently poor in nutrients.…”

The 1996 Chagos Expedition provided an opportunity to study the archipelago's bryophyte flora: 25 of the 55 islands were ecologically investigated, some in more detail than others, and lists and representative collections of mosses, hepatics and other cryptogamic plants were assembled for many of them. Although the islands have a low biodiversity for most of these groups, as would be expected in terms of their relatively young age, remoteness and small terrestrial surface areas, those organisms that are present are often found in abundance and play significant ecological roles. Where the status of taxa on islands has been determined, there appears to be a good correlation between bryophyte biodiversity and island size. Epiphytic bryophytes were not host specific and no epiphyllous species was observed. Biogeographic details are provided, where possible, for the 19 taxa recorded, of which four are new to the Indian Ocean and seven are new to the Chagos Archipelago. A new taxon, Cololejeunea planissima var. chagosensis Pó cs var. nov. is described, and notes and illustrations of a probably new Lejeunea species are provided.
