Evolutionary trade-offs in dormancy phenology

Autor: Théo Constant, F Stephen Dobson, Caroline Habold, Sylvain Giroud

Publikováno v: eLife, Vol 12 (2024)

Seasonal animal dormancy is widely interpreted as a physiological response for surviving energetic challenges during the harshest times of the year (the physiological constraint hypothesis). However, there are other mutually non-exclusive hypotheses

Multiple‐batch spawning as a bet‐hedging strategy in highly stochastic environments: An exploratory analysis of Atlantic cod

Autor: Sara Hočevar, Jeffrey A. Hutchings, Anna Kuparinen

Publikováno v: Evolutionary Applications, Vol 14, Iss 8, Pp 1980-1992 (2021)

Abstract Stochastic environments shape life‐history traits and can promote selection for risk‐spreading strategies, such as bet‐hedging. Although the strategy has often been hypothesized to exist for various species, empirical tests providing f

An empirical test of the bet‐hedging polyandry hypothesis: Female red flour beetles avoid extinction via multiple mating

Autor: Kentarou Matsumura, Takahisa Miyatake, Yukio Yasui

Publikováno v: Ecology and Evolution, Vol 11, Iss 10, Pp 5295-5304 (2021)

Abstract Bet‐hedging via polyandry (spreading the extinction risk of the female's lineage over multiple males) may explain the evolution of female multiple mating, which is found in a wide range of animal and plant taxa. This hypothesis posits that

The Roles of Information Diffusion on Financial Risk Spreading on Two-Layer Networks

Autor: Min Lin, Li Duan, Yanjin Li, Qin Xiao

Publikováno v: Frontiers in Physics, Vol 10 (2022)

The financial risk spreads widely on the financial network and the risk information diffuses broadly on the social networks. How the information diffusion affects the financial risk spreading still lacks mathematical study. This paper proposes a mode
