Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Experimental and Simulation Studies on Bird Strike Impact of Carbon Fiber Composite Laminates with Different Ply Directions

Aerospace
Composite materials are widely used in aircraft due to their high specific strength and stiffness, superior impact resistance, and excellent fatigue performance. Bird strikes can inflict severe damage to critical aircraft components such as the fuselage,

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Corporate Environmental Responsibility and Cost of Equity Capital: A Meta‐Analytical Review

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite extensive research on the relationship between corporate environmental responsibility (CER) and cost of equity capital (COEC), empirical evidence remains inconsistent. This study addresses these inconsistencies through a comprehensive meta‐analysis of 1139 effect sizes from 75 studies.

Do Sustainability Committees Mitigate or Exacerbate ESG Decoupling?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the impact of sustainability committees (SCs) on environmental, social, and governance (ESG) decoupling in US publicly listed firms. In particular, it examines their influence on overall and dimension‐specific (E, S, G) ESG decoupling and distinguishes their effects on internal versus external ESG actions.
