Quantifying landscape‐level biodiversity change in an island ecosystem: a 50‐year assessment of shifts in the Hawaiian avian community

open access: yesEcography, EarlyView.
Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection

Optimizing coordination and trade‐offs between food security and biodiversity conservation goals

open access: yesEcography, EarlyView.
Balancing food security and biodiversity conservation – two often conflicting objectives – is essential for achieving global goals (e.g. SDG 2 and 15; GBF Targets 1, 3, and 10). While previous studies have explored global or national‐level trade‐offs, there is a lack of spatially explicit, scenario‐based planning frameworks at regional scales to ...

Impacts of Pleistocene extinctions on the biomass and energy use of local mammal assemblages around the world

open access: yesEcography, EarlyView.
Many of the world's megafaunal species went extinct during the late Quaternary, leading to dramatic reductions in community and ecosystem functioning. While the nature and severity of the extinctions are well documented on global and continental scales, less is known about local‐scale impacts.

The phytoplankton of an enriched, soft-water lakel subject to intermittent hydraulic flushing (Grasmere, English Lake District) [PDF]

open access: yes, 1982
This paper describes some characteristic features of the phytoplankton of Grasmere, one of the smaller of the principal lakes of the English Lake District, and attempts to relate these to distinctive physical and chemical properties of the lake ...

Extinct Pleistocene carnivores were diurnal and highly active

open access: yesEcography, EarlyView.
There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, the overkill hypothesis explains not only why large mammals in general were highly prone to extinction but suggests that extinction may have been selective ...
