It is crucial to document biodiversity data and to take actions to halt the ongoing massive loss of biodiversity. Yet, these data are poorly defined. We propose a definition of biodiversity data and discuss its implications for data management, enabling enhanced data mobilization for integrated research and efficient conservation strategies.

Climate change has led animal species to shift their ranges to greater elevations, latitudes, and depths, tracking their preferred abiotic niche. However, there is extensive variation in these shifts, and some species have not shifted their ranges at all. Some of this variation arises because species' distributions not only align with the abiotic environment but are also shaped by biotic factors and movement. Through facilitating rapid adaptive responses to climate-mediated changes to abiotic, biotic, and movement factors, behavioral plasticity allows populations to survive environmental change by persisting in place, while also enabling successful establishment in novel habitats when shifting in space.

Many animals rely on deception, including signalling misinformation, to gain advantages over others. While many deceptive strategies rely on deterministic patterns or conditioning, some taxa can flexibly adapt their deceptive behaviour to the identity, perspective, or inferred goals of the observer. These context-dependent deceptive strategies could be considered 'tactical deception' if they rely on higher-level cognitive processes to execute. Here, we outline why cephalopods, such as octopus and cuttlefish, are ideal candidates to explore the link between deception and cognition. As tactical deception relies on understanding differences in one's own and another observer's perspective, we suggest tactical deception as a framework to study aspects of cognition in other animals.

The suppression of recombination between young X and Y chromosomes is a crucial step in their evolution, but why it occurs is not known. The detailed characterization of the polymorphic sex chromosomes of the fourspine stickleback by Liu et al. promises to shed new light on this longstanding question.

Fish are a critical source of accessible nutrition. However, when non-native species introduced through aquaculture establish in the wild, they inevitably alter the structure of ecological networks. This could have unprecedented outcomes for nutrient and toxin accumulation when aquatic food is consumed by humans, with socioeconomically variable impacts.

Zoonotic diseases increasingly threaten human and wildlife populations, driving a global rise in mass-mortality outbreaks, including the ongoing avian influenza panzootic in wildlife and zoonotic spillovers such as the COVID-19 (SARS-CoV-2) pandemic in humans. We introduce a new general framework for detecting and managing pathogen outbreaks using animal movement and sensory biologging data to enhance early outbreak detection, provide near-real-time updates on sentinel host health and mortality, and reveal infection-induced behavioral changes. Integrating past and near-real-time biologging with disease surveillance data also enables prospective assessments of spatiotemporal outbreak dynamics, informs management decisions, helps to mitigate spillover risks, and supports both disease control and wildlife conservation.

Animal contests are central to understanding the evolution of aggressive behaviors and the strategic decisions that shape survival and reproductive success across species. A key aspect of contests is the role of individual costs in determining the outcome. However, despite its obvious meaning, a clear definition of contest costs is lacking. We argue that contest costs have both short- and long-term effects that affect how aggressive behaviors evolve and show that empirical studies rarely connect these two types of cost. To address this gap, we propose methodological approaches that integrate both cost perspectives. As a result, new research integrating short- and long-term contest costs can substantially advance our understanding of strategic decision-making evolution in animal contests.

Oxygen is vital for marine life. Despite global ocean deoxygenation, coastal oxygen dynamics are poorly understood. We synthesise the biological and mechanical processes that shape the coastal oxyscape and how organisms respond to it. Oxygen availability can determine species ecophysiology and affect population dynamics and ecological interactions. We propose a novel conceptual framework to reassess oxygen as a resource that is both density-independent and density-dependent, and identify spatial and temporal patterns of competition in coastal ecosystems. Our framework aims to (i) advance eco-evolutionary theory, (ii) improve species distribution models, (iii) inform effective conservation strategies, and (iv) enhance insight into coastal ecosystem-level responses to oxygen fluctuations, thereby advancing our understanding of environmental complexity under climate change, which in turn can guide management.

Light pollution is an emerging ecological threat. To mitigate its negative consequences, creative inter- and transdisciplinary solutions and societal interactions are needed. To this end, we introduce nocturnal umbrella species representative of light-sensitive biodiversity whose protection will safeguard vital ecosystem services and a wide range of co-occurring species.
