Review of river fisheries valuation in West and Central Africa [PDF]

open access: yes, 2008
This paper provides a review of the valuation of river fisheries in West and Central Africa. It is the general perception that, compared to the biological and ecological aspects of river fisheries, this particular subject area has received relatively ...

Sulfate-reducing prokaryotes in river floodplains

open access: yes, 2007
This thesis constitutes a pioneer attempt at elucidating the ecology of sulfate-reducing prokaryotes in river floodplains. These are non-typical sulfate-reducing environmental settings, given the generally low sulfate concentration that characterize freshwater habitats, and river flow regulation that makes flooding events infrequent.

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

open access: yesBoreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Comprehensive framework for assessing and optimizing existing research networks

open access: yesConservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Global overview of progress in respecting the contributions of traditional knowledge in biodiversity governance

open access: yesConservation Biology, EarlyView.
Abstract Recognition and engagement of Indigenous Peoples and local communities (IP&LCs) and other traditional knowledge (TK) holders in formal biodiversity governance remain limited, despite their significant contribution to the conservation and sustainable use of biodiversity through their knowledge, innovations, practices, and land stewardship.

A climate–habitat–network robustness framework reveals climate‐driven habitat shifts and corridor resilience for milu in China

open access: yesConservation Science and Practice, EarlyView.
Habitat fragmentation and climate change jointly threaten the persistence of wide‐ranging species, posing complex challenges for conservation planning. However, most current connectivity approaches overlook the integration of species‐specific constraints, climate‐driven dynamics, and quantitative robustness assessments. To bridge this gap, we propose a

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider

open access: yesEcological Entomology, EarlyView.
In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

Opportunistic Recharge Enhancement in Arid and Semi‐Arid Regions

open access: yesGroundwater, EarlyView.
Groundwater supplies are increasingly stressed by climatic trends and multiple competing uses, especially in dryland environments. We propose opportunistic recharge enhancement (ORE) as a cross‐disciplinary, scalable framework to augment groundwater supplies by strategically integrating recharge co‐benefits into existing land and water management ...
