Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Satellite hindcasts of foliar traits reveal a subtle but consistent relaxation of conservativeness in a biodiverse mountain grassland over the last four decades

open access: yesEcography, EarlyView.
Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

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.

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

open access: yesEcography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Increasing concentrate feeding level in early lactation dairy cows fed cut herbage linearly decreased methane yield and intensity

open access: yesAnimal Nutrition
The use of supplementary feeds, including concentrates, on New Zealand dairy farms has increased in recent decades and this could have mitigated methane (CH4) emissions by decreasing the forage-to-concentrate ratio. The forage-to-concentrate ratio in the

Simulating past and future refugia for temperate trees in northern Italy

open access: yesEcography, EarlyView.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...

‘SiteTool': a ‘Shiny' application for field site selection and evaluation

open access: yesEcography, EarlyView.
Field studies are fundamental to ecological research, yet many studies rely on unspecified or convenience‐based methods for site selection, potentially introducing bias that can compromise research results. Remote‐sensing data provides a quantitative way to evaluate potential sites without expensive pilot visits; however, interacting with spatial data ...

Integrating phytosociological and agronomic analysis to support the sustainable management of Mediterranean grasslands [PDF]

open access: yes, 2004
The paper analyses the integration of different methodologies for assessing the grazing value of grasslands, aimed at supporting decisions for their sustainable management, that is, the long term preservation of their productive potential.
