Spatial variation of grassland canopy affects soil wetting patterns and preferential flow
Hydrological Processes, Volume 36, Issue 12, December 2022., 2022 Spatially heterogeneous canopy and pre‐event soil moisture conditions changed soil‐wetting patterns. Taller grass, together with drier soil, weakens soil moisture response, probably because of uneven water input and dryness induced preferential flow. Abstract Canopies shape net precipitation patterns, which are spatially heterogeneous and control soil ...

Dynamical phase coexistence: A simple solution to the "savanna problem" [PDF]
, 2010 We introduce the concept of 'dynamical phase coexistence' to provide a simple solution for a long-standing problem in theoretical ecology, the so-called "savanna problem". The challenge is to understand why in savanna ecosystems trees and grasses coexist in a robust way with large spatio-temporal variability. We propose a simple model, a variant of the

Climate Change Mitigation in the Dairy Sector: Uncovering Heterogeneity Through Eco‐Efficiency Clubs
Agribusiness, EarlyView.ABSTRACT Combining climate change goals with economic targets is crucial for the dairy sector, which is a significant contributor to agricultural greenhouse gas (GHG) emissions worldwide. In this paper, we assess economic and climate change implications of dairy production with panel data of Irish dairy farms from 2013 to 2021.

Hydrological Processes, Volume 36, Issue 12, December 2022., 2022 Modelling flow peaks and timing in response to seasonal vegetation change and applied grassland management from high‐intensity grazing, through natural succession to woodland, and conservation farming. Abstract As the frequency and magnitude of storm events increase with climate change, understanding how season and management influence flood peaks is ...

Growth performance of different Epichloë sinensis strains on media with different additives
Grassland Research, 2022 Background Epichloë sinensis is a newly found endophyte species that is frequently involved in symbiosis with Festuca sinensis. There are a little reports on the characteristics of E. sinensis in vitro. Methods In the present study, five E.

Are Namibia's Grasslands Desertifying? [PDF]
Journal of Range Management, 2000 We compared the herbage standing crop on 31 farms along a rainfall gradient in Namibia (southwestern Africa) in 1997 with the results attained for the same gradient by Walter (1939). We found that the slope for the regression of herbage yield on mean annual rainfall in 1997 was 5.93, i.e. 5.93 kg herbage was produced per hectare for every 1 mm increase

Fast Traversability Estimation for Wild Visual Navigation [PDF]
arXiv, 2023 Natural environments such as forests and grasslands are challenging for robotic navigation because of the false perception of rigid obstacles from high grass, twigs, or bushes. In this work, we propose Wild Visual Navigation (WVN), an online self-supervised learning system for traversability estimation which uses only vision.

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 254-271, January 2023., 2023 Abstract Before plant protection product (PPP) marketing authorization, a risk assessment for nontarget soil organisms (e.g., earthworms) is required as part of Regulation (EC) No. 1107/2009. Following a stepwise approach, higher tier earthworm field studies are needed if they cannot demonstrate low long‐term risk based on laboratory studies.
