Developing a macroecology for human‐altered ecosystems

open access: yesEcography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Spatial distribution of acoustic traits in bird assemblages along regional bioclimatic gradients

open access: yesEcography, EarlyView.
Environmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. Exploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients.

Overlooked Parrot Seed Dispersal in Australia and South America: Insights on the Evolution of Dispersal Syndromes and Seed Size in Araucaria Trees

open access: yesFrontiers in Ecology and Evolution, 2019
While Psittaciformes (parrots and allies) are well-recognized as highly-mobile seed predators, their role as seed dispersers has been overlooked until very recently.

Geochemical analysis of Cenozoic fossil conifers at high latitudes: Implications for molecular preservation and environmental change [PDF]

open access: yes, 2010
Fossil materials record ancient life and their adapted environment. Arctic plant fossils are critical for our understanding of the Earth’s paleoenvironment when high latitudes were under ice-free conditions.

Habitat complexity and prey composition shape an apex predator's habitat use across contrasting landscapes

open access: yesEcography, EarlyView.
The spatial ecology of stalk‐and‐ambush predators like the Eurasian lynx Lynx lynx depends on prey availability and environmental features, yet the relative roles of these factors remain unclear at large spatial scales. In this study, we analysed lynx habitat use across central and southern Finland using snow‐track data from the Wildlife Triangle ...

Cellulose Fiber‐Engineered Gradient Interfacial Channels as Ion‐Highways for High‐Loading, Long‐Life Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a papermaking‐inspired strategy to fabricate high‐loading battery electrodes by integrating a cellulose fiber network. This scaffold creates a gradient porous architecture, enabling ultra‐fast electrolyte infiltration and ion transport.

SEASONAL DYNAMICS OF THE CONTENT OF PHOTOSYNTHETIC PIGMENTS IN CONIFEROUS PLANTS UNDER THE CONDITIONS OF THE URBAN ENVIRONMENT

open access: yesИзвестия высших учебных заведений. Поволжский регион: Естественные науки, 2020
Background. The main share in the landscaping of the city of Yoshkar-Ola is made up of such deciduous woody and shrub plantings such as Betula pendula Roth., Tilia cordata Mill., Syringa vulgaris L., Acer negundo L., Populus pyramidalis Salisb., etc ...

Geochemical support for a climbing habit within the Paleozoic seed fern genus Medullosa [PDF]

open access: yes, 2011
A long-standing problem in paleobotany is the accurate identification of the growth habits and statures of fossil plants. Tissue-specific analysis of stable carbon isotope ratios in plant fossils can provide an independent perspective on this issue ...

Letting People in: Redefining Collaboration in Wildland–Urban Interface Governance

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Intensifying wildfire regimes and expanding human settlements into wilderness areas have heightened concerns about the wildland–urban interface (WUI) due to the associated increase in fire risk. However, the WUI presents broader social‐ecological challenges that go beyond wildfire risk and remain understudied.
