Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

open access: yesEcography, 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 far side of capitalism: Institutions and trade financing in Manila during the long eighteenth century

open access: yesThe 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 ...

Synthesizing Archetypes of Social‐Ecological Systems: Identifying Common Building Blocks

open access: yesEnvironmental Policy and Governance, Volume 35, Issue 5, Page 882-897, October 2025.
ABSTRACT A growing number of studies apply the social‐ecological systems (SES) framework with its standardized set of variables to examine place‐based environmental governance. Yet, due to the wide diversity of social‐ecological systems, a general theory about how variables interact—and systems can be governed—lacks empirical support. Despite many case

Differential temporal beta‐diversity patterns of native and non‐native arthropod species in a fragmented native forest landscape [PDF]

open access: yes, 2018
An important factor that hinders the management of non‐native species is a general lack of information regarding the biogeography of non‐natives, and, in particular, their rates of turnover.

Repeated colonization, adaptive radiation and convergent evolution in the sheet‐weaving spiders (Linyphiidae) of the south Pacific Archipelago of Juan Fernandez

open access: yesCladistics, 2020
AbstractWe report on the colonization and diversification of linyphiid spiders in the Pacific oceanic archipelago of Juan Fernandez. About 50 spider species occur naturally in these islands, most of them endemic and about half of them are linyphiids.

New Insights on Dissolved Organic Matter Cycling in the Cape Verde Frontal Zone From Its Optically Active Fraction

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 7, July 2025.
Abstract Absorption and fluorescence spectroscopy have been used to gain new insights on the dynamics of Dissolved Organic Matter (DOM) in the Cape Verde Frontal Zone (CVFZ), a highly dynamic area comprising the thermohaline Cape Verde Front (CVF) and the Cape Blanc Giant Filament (CBGF), which exports organic matter produced over the shelf to the ...
