Hunters and hunting across indigenous and colonist communities at the forestagriculture interface: an ethnozoological study from the Peruvian Amazon
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/96541
Abstract
Background:
Wildlife has been traditionally used by forest communities as a source of protein, and the Peruvian Amazon is no exception. The articulation of colonist and indigenous communities to urban centers and markets results in changes in livelihood strategies and…

QTL analyses for tolerance to abiotic stresses in a common bean (Phaseolus vulgaris L.) population
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/97028
Abstract
Common bean productivity is reduced by several abiotic stress factors like drought and low soil fertility, leading to yield losses particularly in low input smallholder farming systems in the tropics.
To understand the genetics of stress tolerance, and to improve adaptation of common bean to adverse environments, the BAT…

Diversity of global rice markets and the science required for consumer-targeted rice breeding
https://hdl.handle.net/10568/42278
Abstract
With the ever-increasing global demand for high quality rice in both local production regions and with Western consumers, we have a strong desire to understand better the importance of the different traits that make up the quality of the rice grain and obtain a full picture of rice quality demographics. Rice is by no means a ‘one size fits all’ crop. Regional preferences are not only striking, they…

Modeling of crop wild relative species identifies areas globally for in situ conservation
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/101261
Abstract
The impact of climate change is causing challenges for the agricultural production and food systems. More nutritious and climate resilient crop varieties are required, but lack of available and accessible trait diversity is limiting crop improvement. Crop wild relatives (CWR) are the wild cousins of cultivated crops and a vast…

https://hdl.handle.net/10568/109671
Abstract
Some of the largest impacts of climate change are expected in the environmentally heterogeneous and species rich high mountain ecosystems. Among those, the Neotropical alpine grassland above the tree line (c. 2,800 m), known as Páramo, is the fastest evolving biodiversity hotspot on earth, and one of the most…

Understanding the consequences of changes in the production frontiers for roots, tubers and bananas
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/99728
Abstract
The widely recognized role of roots, tubers and bananas (RT&Bs) in achieving food security and providing income opportunities in the world’s poorest regions will be challenged by socioeconomic and climate related drivers. These will affect demand and production patterns and increase pressure on farming systems.…

https://hdl.handle.net/10568/108781
Abstract
While there is consensus on the need to promote agricultural development in Africa to achieve food security and use agriculture as an engine of growth, there is a lively policy debate on appropriate policies to achieve this goal. In the past two decades, there has been a revival of policies that favor government support to…

Conceptual toolboxes for twenty-first-century ecologists
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/90998
Abstract
We ecologists realize that individually we have a variety of interests, knowledge, and skills among us; and we appreciate how those attributes differentially apply to the diverse tasks we address in our various “practices” of ecology. Less obvious to us, however, is the variety of intellectual tools we bring to bear in our practices. In order to understand how…

A metabolomics characterisation of natural variation in the resistance of cassava to whitefly
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/106065
Abstract
Abstract
Background
Cassava whitefly outbreaks were initially reported in East and Central Africa cassava (Manihot esculenta Crantz) growing regions in the 1990’s and have now spread to other geographical locations, becoming a global pest severely affecting farmers and smallholder income. Whiteflies impact plant yield via…

Explaining andean potato weevils in relation to local and landscape Features : A facilitated ecoinformatics approach
International Potato Center (CIP)

Abstract
Background: Pest impact on an agricultural field is jointly influenced by local and landscape features. Rarely, however, are these features studied together. The present study applies a “facilitated ecoinformatics” approach to jointly screen many local and landscape features of suspected importance to Andean potato weevils…

Abstract
The genus Phaseolus, native to the Americas, is composed of more than eighty wild species, five of which were domesticated in pre-Columbian times. Since the beginning of domestication events in this genus, ample opportunities for gene flow with wild relatives have existed. The present work reviews the extent…

Abstract
Land-use change and intensification threaten bee populations worldwide, imperilling pollination services. Global models are needed to better characterise, project, and mitigate bees' responses to these human impacts. The available data are, however, geographically and taxonomically unrepresentative; most data are…
