Fungal ecology in the age of 'omics

New Phytologist, EarlyView.
Summary The advancement of technology in recent decades has given us an unprecedented ability to observe the natural world. With modern sequencing and bioinformatics technologies, we can obtain more information about the microscopic world, and its interactions with the macroscopic world, than ever before.

Compactação do Solo Sob Sistemas de Manejo Convencionais e Conservacionistas

Revista Engenharia na Agricultura - REVENG, 2009
Os sistemas de manejo do solo influenciam a sua susceptibilidade à compactação. Esta é uma das principais causas da degradação física do solo. O objetivo deste trabalho foi avaliar a resistência do solo à penetração e a densidade do solo de um Latossolo Vermelho distrófico, cultivado sob diferentes sistemas de preparo do solo.

Field assessment of nitrogen sources in Brassica carinata using physiological indicators of nitrogen status under temperate no‐till conditions

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Improving nitrogen (N) use efficiency in Brassica carinata is essential to sustain yield and lower biofuel carbon intensity under variable field conditions. We hypothesized that integrating physiological indicators, such as the nitrogen nutrition index (NNI) and the critical nitrogen uptake curve (CriNUC), into N management frameworks would ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Fine‐tuning the buzz: comparing visitation frequency and pollination effectiveness in plant–pollinator networks

New Phytologist, Volume 249, Issue 4, Page 2140-2152, February 2026.
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.
