Integration of Nile tilapia (Oreochromis niloticus) and vegetables (Amaranthus hybridus and Brassica rapa pekinensis) for improved production, water use efficiency and nutrient recycling

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 493-506, December 2022., 2022
Abstract Sustainable agriculture intensification is an urgent challenge in developing countries including Tanzania. One potential solution is to adopt farming systems that increase farm production by optimizing resource use efficiency, and integrated aquaculture system, which involves farming of fish and crops, is an example of such systems.

Exergoenvironmental damages assessment in a desert‐based agricultural system: A case study of date production

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3155-3172, November/December 2022., 2022
Abstract Developing countries, especially those in hot and dry areas, need more attention to achieve sustainable development as they apply excessive inputs in production processes. The present study aims to quantify the amount of environmental emissions and determine the most appropriate pattern of energy use in the date (Phoenix dactylifera L ...

Cropping system diversity and tillage intensity affects wheat productivity in Texas

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3498-3514, November/December 2022., 2022
Abstract Wheat (Triticum aestivum L.) production in Texas depends heavily on conventional tillage (CT) and a long summer fallow period, which contributes to soil degradation. This study compared the impact of reducing tillage intensity (CT, no‐tillage, and strip‐tillage) combined with summer cropping to CT–summer fallow on wheat establishment, grain ...

Risk of subsequent primary lymphoma in a cohort of 69,460 five‐year survivors of childhood and adolescent cancer in Europe: The PanCareSurFup study

open access: yesCancer, Volume 129, Issue 3, Page 426-440, 1 February 2023., 2023
Abstract Background Survivors of Hodgkin lymphoma (HL) are at risk of developing non‐Hodgkin lymphoma (NHL) after treatment; however, the risks of developing subsequent primary lymphomas (SPLs), including HL and NHL, after different types of childhood cancer are unknown.

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta‐analysis in insects

open access: yesEvolution Letters, Volume 6, Issue 6, Page 394-411, December 2022., 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

National characterization of pesticide runoff and erosion potential to put USEPA standard ecological scenarios in context for pyrethroids

open access: yesIntegrated Environmental Assessment and Management, Volume 19, Issue 1, Page 175-190, January 2023., 2023
Abstract Decision‐making for pesticide registration by the US Environmental Protection Agency (USEPA) relies upon crop‐specific scenarios in a tiered framework. These standard modeling scenarios are stated to represent “…sites expected to produce runoff greater than would be expected at 90% of the sites for a given crop/use.” This study developed a ...

Neither, either, or both? Who sees GM and non‐GM food labels?

open access: yesJournal of the Agricultural and Applied Economics Association, Volume 1, Issue 4, Page 385-401, December 2022., 2022
Abstract The US National Bioengineered Food Disclosure Standard mandates disclosures on foods containing genetically modified (GM) ingredients, while allowing voluntary non‐GM claims to coexist in the marketplace. Using cross‐sectional survey data, accounting for error term correlation and controlling for demographic variability, we describe the types ...

A Method for Estimating Alfalfa (Medicago sativa L.) Forage Yield Based on Remote Sensing Data

open access: yesAgronomy, 2023
Alfalfa (Medicago sativa L.) is a widely planted perennial legume forage plant with excellent quality and high yield. In production, it is very important to determine alfalfa growth dynamics and forage yield in a timely and accurate manner.

The niche complementarity driven by rhizosphere interactions enhances phosphorus‐use efficiency in maize/alfalfa mixture

open access: yesFood and Energy Security, 2020
Rhizosphere interactions between intercropping maize and alfalfa to increase phosphorus (P) acquisition remain largely unknown. This study aimed to investigate the mechanisms underlying niche complementarity to increase P acquisition in the maize/alfalfa

Dietary yolk supplementation decreases rates of yolk deposition in Japanese quail

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 63-73, January 1, 2023., 2023
Dietary supplementation with egg yolk decreases the rate of yolk deposition in quail. Quail with high body condition indices deposit yolk more slowly. Abstract Generation of egg yolk by birds requires the synthesis and deposition of large amounts of protein and lipid, and is often accompanied by the incorporation of additional physiological mediators ...
