Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Integrating indigenous crops in agroforestry systems: Lesser yam and teak mixed systems are more profitable than monocultures in Indonesia

PLANTS, PEOPLE, PLANET, EarlyView.
Major staple crops are often introduced and cultivated in monocultures. Yams are staple crops native to the majority of low‐ and middle‐income countries and can provide an alternative to introduced staple crops. We showed that lesser yams cultivated together with teak trees (planted at the border of the farm) are more profitable than lesser yam ...

Influence of adjacent crop type on occurrence of California ground squirrels on levees in the Sacramento Valley, California

Wildlife Society Bulletin, 2014
In the Sacramento Valley in California, USA, burrowing activities of California ground squirrels (Otospermophilus beecheyi) on levees pose a threat to human safety and property by potentially compromising levee integrity during a flood event.

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture

PLANTS, PEOPLE, PLANET, EarlyView.
Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

The Effects of Different Crop Rotations on the Quality of Saline Soils in the Yinbei Plain

Agronomy
Rice cultivation has the ability to ameliorate saline soils, but this monoculture pattern can lead to negative plant–soil feedback. In a previous study, we investigated the effects of long-term rice cultivation on saline soil chemistry, salt ions, root ...

An integrated model of perennial and annual crop production for Sub-Saharan countries [PDF]

Crop production in sub-Saharan Africa is dominated by smallholders who allocate household labor across annual and perennial crops and, in some cases, to wage labor markets. This paper develops a microeconomic model of household choice which is consistent

Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

Pest Management Science, EarlyView.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

Adoption of inland valley farming and rice production practices: Evidence from smallholder farmers in Côte d’Ivoire and Ghana

Agricultural and Resource Economics Review
Inland valley wetlands in West African countries are considered to hold immense potential for rice-based production systems. Policies to increase rice production in inland valleys have until now not lived up to expectations.

Genome-wide association study identifies genomic regions under selection for domestication and agronomic traits in intermediate wheatgrass. [PDF]

Plant Genome
Abstract Intermediate wheatgrass (IWG) (Thinopyrum intermedium, Kernza) is a perennial forage grass undergoing neo‐domestication as a grain crop. IWG provides numerous ecosystem services and has the potential to benefit rural communities as an alternative crop option with high market value.
