Petrology of some oceanic island basalts: PRIMELT2.XLS software for primary magma calculation [PDF]

open access: yes, 2008
PRIMELT2.XLS software is introduced for calculating primary magma composition and mantle potential temperature (TP) from an observed lava composition. It is an upgrade over a previous version in that it includes garnet peridotite melting and it detects ...

A summary of the oldest ages for the world's islands [PDF]

open access: yes, 1976
The oldest ages of rocks on the world's islands are summarized (Oligocene or older) based on published literature. All the oceans and perhaps all the seas contain a few continental islands, indicative of debris left from continental rifting prior to ...

Excavation at Aguas Buenas, Robinson Crusoe Island, Chile, of a gunpowder magazine and the supposed campsite of Alexander Selkirk, together with an account of early navigational dividers [PDF]

open access: yes, 2007
Excavations were undertaken of a ruined building at Aguas Buenas, identified as an 18th-century Spanish gunpowder magazine. Evidence was also found for the campsite of an early European occupant of the island.

Decision analysis rooted in Indigenous and Western scientific knowledge identifies cost‐effective strategies for managing hyperabundant deer to restore keystone places

open access: yesPeople and Nature, Volume 8, Issue 1, Page 4-20, January 2026.
Abstract The hyperabundance of herbivores—a result of altered human relationality with the land and the extirpation of predators—is leading to large‐scale degradation of keystone ecosystems across the globe. Designing and implementing socially acceptable and cost‐effective strategies that meaningfully reduce herbivore populations while allowing for the

Importance of nest attributes in the conservation of endemic birds of the Juan Fernández Archipelago, Chile [PDF]

open access: yesBird Conservation International, 2011
SummaryUnderstanding the particular nesting ecology of island endemic species represents the first step in identifying suitable micro-habitats and establishing efficient management programmes. This could become even more important when island bird assemblages are prone to invasion by ecologically similar species that may eventually cause niche ...

Do Island Spiders Descend From Trees? – A Tale of Island Colonisation and Niche Expansion

open access: yesJournal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim Oceanic islands are known for being home to drastically different communities compared to the mainland, as their isolation and limited area significantly favour clades able to travel long distances over water. On spiders, this happens mainly, although not exclusively, through ballooning whose propensity is unevenly distributed across ...

Topography-driven isolation, speciation and a global increase of endemism with elevation [PDF]

open access: yes, 2016
Aim: Higher-elevation areas on islands and continental mountains tend to be separated by longer distances, predicting higher endemism at higher elevations; our study is the first to test the generality of the predicted pattern.
