Allozyme diversity in endemic flowering plant species of the Juan Fernandez Archipelago, Chile: ecological and historical factors with implications for conservation [PDF]
American Journal of Botany, 2001 The level and apportionment of allozyme diversity were determined for 29 endemic (and 1 native) species from the Juan Fernández Islands, Chile. Mean diversities at the species level (Hes = 0.065) are low but comparable to those measured for other insular endemics in the Pacific.

People 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]
Bird 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
Journal 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 ...

Ecography, Volume 2025, Issue 11, November 2025.About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...

The Economic History Review, Volume 78, Issue 4, Page 1068-1087, November 2025.Abstract Sustained long‐distance trade in the early modern era necessitated institutional mechanisms capable of solving three interrelated challenges: the need to mobilize an unprecedented volume of capital and to lock it in for long periods of time, ways of mitigating the principal–agent problem across continents, and methods to internalize and ...

Evidence of sequential hermaphroditism in alfonsinos (Beryx spp.) from the deep northeast Atlantic
Journal of Fish Biology, Volume 107, Issue 5, Page 1833-1838, November 2025.Abstract Among 572 specimens of Beryx splendens and B. decadactylus collected in the Azores (northeast Atlantic), we identified 66 hermaphroditic females, primarily of medium size and at early stages of gonadal development. Hermaphroditism was observed more frequently in winter for B. splendens and in spring–summer for B. decadactylus.
