Effects of Temperature Peaks and Water Stress on Tropical Seed Germination: Experimental Trials With Species From Brazil's Northeastern Coastal Zone

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Understanding the effects of high temperatures and water deficit on germination provides valuable insights into seed stress tolerance, guiding the use of native seeds in ecological restoration. This study aimed to evaluate the effects of (1) temperature peaks and (2) water stress treatments and post‐stress recovery on the germination of some ...

Are Growth Bands in Macadamia integrifolia Annual?

Ecological Management &Restoration, Volume 27, Issue 3, September 2026.
ABSTRACT Although two of the four Australian endemic Macadamia species are well known as horticultural crops, little is understood about their use by First Nations peoples or their longevity. Robust age estimation of the age attainable by Macadamia integrifolia would help inform conservation planning and cultivation.

Allelopathy and Allelochemicals in Grasslands and Forests

, 2023
Plants can produce and release allelochemicals to interfere with the establishment and growth of conspecific and interspecific plants. Such allelopathy is an important mediator among plant species in natural and managed ecosystems. This review focuses on

Socio‐Economic Impacts, Farmer Perception and Management Responses to the Invasive Weed Parthenium hysterophorus L. in Uganda

Weed Research, Volume 66, Issue 5, September/October 2026.
ABSTRACT The invasive weed Parthenium hysterophorus L. presents a severe socio‐economic threat to Ugandan agriculture. This nationwide study of 244 farmers in infested districts reveals near‐universal recognition of the weed and widespread negative impacts: 88.3% of the farmers report increased labour demands, 62.1% cite yield reduction and significant

Mathematical Modelling of Allelopathy: IV. Assessment of Contributions of Competition and Allelopathy to Interference by Barley

Dose-Response, 2005
One of the main challenges to the research on allelopathy is technically the separation of allelopathic effect from competition, and quantitatively, the assessment of the contribution of each component to overall interference. A simple mathematical model
