The myth of the metabolic baseline: sleep–wake cycles undermine a foundational assumption in organismal biology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Disentangling the Effects of Firm‐Level Climate Risk and Capital Market Signalling: Evidence From Stock Price Informativeness

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines the impact of firm‐level climate risk on stock price informativeness (SPI) through the integrated lens of stakeholder–shareholder theory. Using a global unbalanced panel of 73,770 firm‐year observations across 38 countries (2000–2020), we find that higher carbon emissions significantly reduce SPI, reflecting increased ...

Does ESG Investing Pay off? Comparing the Performance of ESG and Traditional ETFs Across European and US Markets

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Investors have long recognized the importance of firms in promoting sustainability, leading to the rise of socially responsible investment (SRI). Specifically, there is a growing preference for exchange‐traded funds (ETFs) that prioritize environmental, social, and governance (ESG) principles.

Sufficient Conditions for Wiener Index, Hyper-Wiener Index and Harary Index of the Hamilton Graph

open access: yesMathematics and Computer Science
The topological index can be used to depict the structural properties of graphs, and the Hamiltonian problem of graphs has always been a classical problem in graph theory. In this work, we use some known conditions to give some sufficient conditions for Hamilton graphs by the Wiener index, Hyper-Wiener index and Harary index of a graph.
