Income sharing for common pool resources with uncertain productivity

American Journal of Agricultural Economics, EarlyView.
Abstract We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by means of an income sharing mechanism mitigates externalities and hence ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics

American Journal of Botany, EarlyView.
Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

The Effects of Self-Pollination on Seed Development and the Process of Oil and Squalene Accumulation in Camellia oleifera

Liang you shipin ke-ji
Camellia oleifera is a self-incompatible plant. This study examined the effects of self-pollination on seed development, and the accumulation of oil and squalene in seeds using Yunyoucha No. 4, which has been widely cultivated-in Yunnan Province.

Manual cross-pollination on the profitability of a pitaya orchard with self-compatible and self-incompatible species

Revista Agrogeoambiental
The high dependence on cross-pollination in self-incompatible pitaya species causes low productivity. The objective, with the accomplishment of this work, was to compare the profitability of the pitaya orchard with the management of manual cross ...

Arbosana Olive Is Self-Incompatible, but Inter-Compatible with Some Other Low-Vigor Olive Cultivars

Horticulturae
Trendy high-density olive fields are often monovarietal orchards, mostly using the cultivar Arbequina. However, Arbequina shows a strong self-incompatibility response, and its yields depend on wind cross-pollination, which is not always available.

Engineering Biology Beyond Single Genes: Advances and Challenges in Multiplex Genome Editing

Animal Research and One Health, EarlyView.
Multiplex genome editing is transforming genome engineering from single‐gene perturbation to network‐level control, yet its broader application remains limited by challenges in gRNA array engineering, delivery technologies, and safety management. Emerging AI‐driven approaches are accelerating guide RNA design and CRISPR effector optimization for ...
