Problems for Evaluation of the Scenario of the Permian -Triassic Boundary Biotic Crisis and of Its Causes

Geologia Croatica, 2010
Determination of the causes of the Permian -Triassic boundary(PTB) biotic crisis is hindered primarily by the diachronous nature ofthe used PTB, poor stratigraphic control of compared Upper Permianand Lower Triassic faunas, espec ially in cont inental ...

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

Ecography, EarlyView.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Common bean pan-genome reveals abundant variation patterns and relationships of stress response genes and pathways

BMC Genomics
Long-term geographical isolation and the different directions of domestication can cause a large number of genome variations. Population genetic analysis based on a single reference genome cannot capture all the variation information.

Climatic, edaphic, and biotic controls over storage and turnover of carbon in soils [PDF]

, 1994
Soil carbon, a major component of the global carbon inventory, has significant potential for change with changing climate and human land use. We applied the Century ecosystem model to a series of forest and grassland sites distributed globally to examine

Harnessing the power of machine and deep learning for transferring joint species distribution models considering the structure of biotic interactions

Ecography, EarlyView.
The transferability of single or joint species distribution models ((j)SDMs) depends on their ability to predict beyond the observed environmental range and to remain consistent despite shifts in biotic interactions. Transfer accuracy may be improved by recent advances in the application of deep learning that provide greater flexibility and potentially

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Brewing By-Products: Source, Nature, and Handling in the Dawn of a Circular Economy Age

Biomass
The brewing industry generates vast amounts of by-products of biotic and abiotic nature that require proper handling to reduce their environmental footprint annually. Simultaneously, and in alignment with the current circular economy dynamics, there is a
