Temperature and day length drive local adaptation in the Patagonian foundation tree species Nothofagus pumilio
(BioRxiv, 2023-04-29)Climate change alters relationships among environmental conditions and thus has the potential to change the selection pressures acting on adaptive gene variants. Using a landscape genomic approach, we show that the southern ... -
Towards environmentally sound intensification pathways for dairy development in the Tanga region of Tanzania
(Springer, 2020-11)The gap between milk demand and domestic supply in Tanzania is large and projected to widen. Meeting such demand through local production of affordable milk presents an opportunity to improve the welfare of producers and ... -
Modelling the establishment, spread and distribution shifts of pests
(Taylor and Francis, 2019)During the last century increasing human trade networks have interacted with other global changes – such as land use and climate change – to accelerate the range expansion of pest species worldwide. In this special issue, ... -
Influence of adult diet on fitness and reproductive traits of the egg parasitoid Anagrus virlai (Hymenoptera: Mymaridae), a potential biocontrol agent against the corn leafhopper
(Wiley, 2020-08)Dalbulus maidis is the most important leafhopper pest of maize in the Americas. Anagrus virlai is an egg parasitoid commonly associated with the corn leafhopper. We evaluated whether the performance of A. virlai is dependent ... -
Think globally, measure locally: The MIREN standardized protocol for monitoring plant species distributions along elevation gradients
(Wiley, 2022-02)Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their elevational ranges. Range ... -
Antimicrobial resistance dissemination associated with intensive animal production practices in Argentina: A systematic review and meta-analysis
(Elsevier, 2023-03)Abuse and misuse of antimicrobial agents has accelerated the spread of antimicrobial-resistant bacteria. The association between antimicrobial-resistant infections in humans and antimicrobial use in agriculture is complex, ... -
Revisiting the influence of learning in predator functional response, how it can lead to shapes different from type III
(Wiley, 2022-02)Predator/parasitoid functional response is one of the main tools used to study predation behavior, and in assessing the potential of biological control candidates. It is generally accepted that predator learning in prey ... -
Three easy fixes for sire use can enhance genetic progress in community-based breeding programmes
(Wiley, 2021)We analysed options to optimize the use of sires in sheep and goat community-based breeding programmes (CBBP) for three scenarios occurring under field conditions: premature sale of selection candidates, fixed service ... -
Are invasive species promoting yellowjacket invasion in Patagonia?
(Wiley, 2022-06)In recent decades, yellowjacket wasps, including Vespula vulgaris, have successfully been established in Patagonia. Additionally, the invasive willow Salix fragilis has also invaded areas next to watercourses, which in ... -
Genetic progress and economic benefit of community-based breeding programs for sheep out- and upscaling options in Ethiopia
(Elsevier, 2019-08)In this study, expected genetic progress and economic benefits from implementing three community-based breeding programs for sheep (CBBP) out- and upscaling strategies were investigated. Strategy 1 is to replicate average ... -
Converting multi-trait breeding objectives into operative selection indexes to ensure genetic gains in low-input sheep and goat breeding programmes
(Elsevier, 2021-05)Small ruminant breeding programmes in low-input production systems are best organised at the community level. Participant farmers have to agree on goal traits and their relative importance. When BLUP breeding values of ... -
How to succeed in implementing community-based breeding programs: Lessons from the field in Eastern and Southern Africa
(Frontiers Media, 2023-03)Breeding programs involving either centralized nucleus schemes and/or importation of exotic germplasm for crossbreeding were not successful and sustainable in most Africa countries. Community-based breeding programs (CBBPs) ... -
Soil bacterial biodiversity characterization by flow cytometry: The bottleneck of cell extraction from soil
(Wiley, 2022-07)The importance of soil biodiversity is increasingly recognized in agriculture and natural resource research and development. Yet, traditional soil biodiversity assessments are costly and time-consuming, limiting the extent ... -
Urban, periurban and horticultural landscapes – Conflict and sustainable planning in La Plata district, Argentina
(Elsevier, 2022-06)Globally, urban areas are expanding onto high-quality agricultural soils and natural environments reducing the area available for food production. The Horticultural Belt of La Plata is one of the main horticultural areas ... -
Estimation and analysis of insect population dynamics parameters via physiologically based models and hybrid genetic algorithm MCMC methods
(Elsevier, 2023-11)Decision support systems are gaining importance in several fields of agriculture, forest, and ecological systems management. Their predictive potential, entrusted to mathematical models, is of fundamental importance to set ... -
Effects of climate on the radial growth of mixed stands of Nothofagus nervosa and Nothofagus obliqua along a precipitation gradient in Patagonia, Argentina
(Elsevier, 2022-08)Climate models for North Patagonia in Argentina project dryer conditions, due to a decrease in mean precipitation combined with an increase in mean temperatures. The temperate mixed Nothofagus forest, which exists along a ... -
A new model formulation for host depletion in parasitoids
(Elsevier, 2023-01)A new model of host depletion in the functional response of parasitoids is presented. Most existing models describe the dynamics of prey consumption as a sequential-memoryless/Markovian process of searching for, handling, ... -
A simple method to select high superovulatory responder goats
(Elsevier, 2023-01)In most female mammals, a common drawback to multiple ovulation embryo transfer programs is the variability in the superovulatory response to the multidose pFSH treatment. The aim of the present study was to identify embryo ... -
Rise from the ashes! Resilience patterns in Patagonia pastoralist communities
(Wiley, 2023-07)Pastoral household resilience is shaped by the interplay between human agency and community resilience mechanisms. As a major component of pastoral household livelihoods, livestock can serve as an indicator to characterize ... -
Characterization of the growth, productivity and physical fiber properties of indigenous cashmere goats in southern Kyrgyzstan
(Elsevier, 2023-09)Since 2008, a breeding flock of Kyrgyz indigenous goats has been developed by a Kyrgyz non-government organisation (NGO) in the mountainous region of Osh Province in southern Kyrgyzstan, to preserve, select and distribute ...
