Biocultural diversity is central to the nutrition, resilience, and adaptive capacity of Indigenous and traditional peoples, who collectively maintain the longest ongoing human experiences with the provision of food under environmental change. In the form of crops and livestock and associated knowledge on their cultivation and use, food-related bioc...
The video provides an interesting story line of a farmer in Bolivia who is using native pottoe diversity to restore degraded lands. He is a custodian farmer conserving 5 varieties of native potatoes grown on degraded lands on his farm. He produces certified seed of these native potatoe varieties for distribution to to ther farmers. His farm is also...
To generate evidence on increasing household resilience to climate change through increased farm income while also generating social benefits, a Cost-Benefit Analysis (CBA) study was undertaken in 2021 by the International Institute of Rural Reconstruction (IIRR) with support from the International Research and Development Center (IDRC). For the Ph...
As part of the Integrated Seed Sector Development in Africa (ISSD Africa) program’s activities for 2020, the Agrobiodiversity, seeds and climate change action learning group (Theme 3) documented and analyzed a series of good crop diversification practice cases from Africa, which were published in an ISSD Africa working paper [https:// hdl.handle.ne...
Comparative phylogeography has become a powerful approach in exploring hidden or cryptic diversity within widespread species and understanding how historical and biogeographical factors shape the modern patterns of their distribution. Most comparative phylogeographic studies so far focus on terrestrial and vertebrate taxa, while aquatic invertebrat...
In recent years, a number of international initiatives have piloted various forms of support for novel configurations of actors to work together to conserve and use agrobiodiversity in sustainable agricultural production systems and to equitably share benefits derived from those activities. These configurations operate at farm, community, national ...
Pleistocene climatic fluctuations (PCF) are frequently highlighted as important evolutionary engines that triggered cycles of biome expansion and contraction. Although there is ample evidence of the impact of PCF on biodiversity of continental biomes, the consequences in insular systems depend on the geology of the islands and the ecology of the ta...

Lineage dispersal is a basic macroevolutionary process shaping the distribution of biodiversity. Probabilistic approaches in biogeography, epidemiology, and macroecology often model dispersal as a background process to explain extant or infer past distributions. We propose framing questions around the mode, timing, rate, and direction of lineage di...

During the Cretaceous, diversifications and turnovers affected terrestrial vertebrates experiencing the effects of global geographical change. However, the poor fossil record from the early Late Cretaceous has concealed how dinosaurs and other terrestrial vertebrates responded to these events. I describe two dinosaurs from the Santonian to Early Ca...
The covariance allocation principle is one of the most widely used capital allocation principles in practice. Risks change over time, so capital risk allocations should be time-dependent. In this paper, we propose a dynamic covariance capital allocation principle based on the variance-covariance of risks that change over time. The conditional corre...
