Plant‐Pollinator Interactions in Grasslands Established on Arable Land

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We compared plant‐pollinator networks in newly established and old, permanent grasslands in a Central European agricultural landscape. Newly established grasslands showed higher pollinator visitation frequency and diversity per plant species, especially for solitary bees and syrphids, with a comparable network structure to old grasslands.

Dynamics and distribution of weed species in weed associations

open access: yesThe Indian Journal of Agricultural Sciences, 2019
Dynamics of weed density with a natural background of weeds in agrophytocenoses of sainfoin (Onobrychis sativa L.), birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.), pure grown (100%) and in mixtures with cocksfoot (Dactylis ...

Preliminary evaluation of perennial forage legumes for organic farming in Finland [PDF]

open access: yes, 2003
In 1998-2001 fourteen forage legume species were evaluated for their productivity in mixed organic swards. The aim was to find new alternatives for red clover. Medicago falcata produced the highest dry matter yield (about 11 000 kg/ha/year).

Improving Prediction of Heterotrophic Respiration in Response to Altered Precipitation

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Soil heterotrophic respiration (Rh) is a key process in the global carbon (C) cycle, strongly influenced by interactions between soil temperature and moisture. It is well documented how soil temperature regulates Rh. However, temperature interacts with soil moisture to regulate Rh via dynamic and complex microbial mechanisms, leading to ...

Metabolism of soluble proteins by rumen microorganisms and the influence of condensed tannins on nitrogen solubility and degradation [PDF]

open access: yes, 2004
The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused on improving amino acid supply to the duodenum by increasing ...

Temperature and the evolution of flower color: A review

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

In vitro effects of three woody plant and sainfoin extracts on two parasitic stage of 3 parasitic nematode species [PDF]

open access: yes, 2004
Most studies on the effects of tanniferous plants on nematodes have examined forages but have neglected the woody plants. Therefore, in vitro effects of extracts from 3 woody plants (Rubus fructicosus, Quercus robur, Corylus avellana) have been tested on

Projecting spatiotemporal bioclimatic niche dynamics of endemic Pyrenean plant species under climate change: how much will we lose?

open access: yesEcography, Volume 2026, Issue 1, January 2026.
Species distributions are shifting under global change, with mountain ecosystems among the most vulnerable. In such landscapes, the ability to track changing conditions is limited, threatening narrowly distributed species. As a mountain biodiversity hotspot in southwestern Europe, the Pyrenees harbors many such species, making it a key case study for ...
