Weed seed bank dynamics under various rotations and field production resources
پژوهشهای زراعی ایران, 2009 Weed seed bank dynamics in corn, sugar beet and wheat plots in rotation with wheat were studied under conventional and ecological management systems during 2 years. The experiment was laid out in a split- plot design in a randomized complete block, where

Effects of grazing and fire on herbaceous species in the Bolivian Altiplano [PDF]
, 2012 High mountain rangelands had been under human land use for millennia in most parts of the world. Traditional land care systems led to highly diverse and stable ecosystems.

Integrating machine learning, deep learning, and image analysis for seed species classification
Applications in Plant Sciences, EarlyView.Abstract Premise The growing demand for wildflower seeds in ecological restoration requires reliable species identification, yet current market products often contain heterogeneous species. As seed identification is labor‐intensive and requires advanced botanical knowledge, we evaluated multiple segmentation and classification approaches to determine ...

What drives animal responses to high severity fire? The role of functional traits
Biological Reviews, EarlyView.ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Land birds on atolls: diversity, origin, and function
Biological Reviews, EarlyView.ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Business Strategy and the Environment, EarlyView.ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

Small-scale seed-bank patterns in a forest soil
Seed Science Research, 2009 AbstractThe forest seed bank has been demonstrated to vary spatially at scales from 2 to 10 m. To our knowledge, the fine-scale spatial structure, i.e. < 2 m, has not been studied before. This study aims to make a thorough investigation of fine-scale spatial structure.
