White Is a New Shade of Blue Carbon: A Case Study of a Traditional Salt Production Pond That is a Net Carbon Sink

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract To address for the first time the carbon budget of traditional salterns, we measured the diel, seasonal, and spatial variability of water‐air CO2‐eq fluxes (CH4 and CO2) and the Organic Carbon (OC) stock and burial rate in the sediment. Temperature, salinity, dissolved oxygen, pH and wind were assessed as potential environmental drivers of the

Winter Bird Assemblages in Rural and Urban Environments: A National Survey [PDF]

open access: yes, 2015
Urban development has a marked effect on the ecological and behavioural traits of many living organisms, including birds. In this paper, we analysed differences in the numbers of wintering birds between rural and urban areas in Poland. We also analysed

Thresholding species distribution models: Simple approaches for land‐use planning in multifunctional landscapes

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1462-1479, May 2026.
Abstract Species distribution models (SDMs) are often used to understand changes to species' distributions and their habitats under different land‐use scenarios, enabling decision makers to prioritize areas for management efforts and balance environmental conservation with socio‐economic demands on the landscape.

Long‐Term Trends of Adult Survival and Productivity in European Songbirds: Role of Migration Strategy and Temperature Gradient Within Species' Ranges

open access: yesDiversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim To understand species population ecology, we need to study how trends of demographic drivers change over time and space, especially so under current rapid climate change. However, knowledge on long‐term trends of survival and productivity, especially using multiple species over large spatial scales, is scarce.

Mortality in organic free-range chickens and molecular characterization of the involved pathogens [PDF]

open access: yes, 2003
Longitudinal investigations on causes of mortality were carried out at one organic layer farm with four flocks of Lohman Brown and Lohman White chickens producing table eggs. All flocks were housed separately.

An Ecological Modelling Approach to Support Peru Wildlife Conservation Planning Based on Geospatial Datasets and Remote Sensing Information

open access: yesDiversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim Peru, a megadiverse country, has developed conservation plans for some threatened wildlife species. This study produced spatially explicit data integrating Species Distribution Models (SDMs) into a geospatial analysis of connectivity within the protected areas (PAs) network.

The caliph and the falcons: a ninth‐century history from Iceland to Iraq

open access: yesEarly Medieval Europe, Volume 34, Issue 2, Page 299-322, May 2026.
In the late ninth and early tenth centuries, an extraordinary number of falcons were given to the ʿAbbāsid caliphs in Baghdad, many of which were white. Gifts from competing dynasties in the northern provinces of the Caliphate, at least some of these birds were almost certainly gyrfalcons from near the Arctic Circle.

Thinking with Birds: Mary Elizabeth Barber’s Advocacy for Gender Equality in Ornithology [PDF]

open access: yes, 2015
This article explores parts of the first South African woman ornithologist’s life and work. It concerns itself with the micro-politics of Mary Elizabeth Barber’s knowledge of birds from the 1860s to the mid-1880s.
