ABSTRACT Understanding the movement patterns and behavior of marine organisms is fundamental for numerous ecological, conservation and management applications. Over the past several decades, advancements in tracking technologies and analytical methods have revolutionized our ability to study marine animal movements. Oceanic zooplankton often make up the bulk of the macroscopic animal biomass in the oceans, yet we know very little about the life histories, migrations and long-term behaviors of these ecologically important animals. In this Review, we consider recent developments in marine movement ecology and animal tracking techniques of gelatinous zooplankton, and discuss the challenges, opportunities and future directions in this rapidly evolving field.

Learning and Animal Movement
Integrating diverse concepts from animal behavior, movement ecology, and machine learning, we develop an overview of the ecology of learning and animal movement. Learning-based movement is clearly relevant to ecological problems, but the subject is rooted firmly in psychology, including a distinct terminology. We contrast this psychological origin of learning with the task-oriented perspective on learning that has emerged from the field of machine learning. We review conceptual frameworks that characterize the role of learning in movement, discuss emerging trends, and summarize recent developments in the analysis of movement data. We also discuss the relative advantages of different modeling approaches for exploring the learning-movement interface. We explore in depth how individual and social modalities of learning can matter to the ecology of animal movement, and highlight how diverse kinds of field studies, ranging from translocation efforts to manipulative experiments, can provide critical insight into the learning process in animal movement.

Abstract Rivers are efficient corridors for aquatic animals, primarily under the assumption of perennial flow. However, the recognition that river drying is a common and widespread phenomenon requires reexamining animal movement through river networks. Intermittent rivers and ephemeral streams have been overlooked when studying animal movement, even though approximately 60% of the global river network dries. In the present article, we extend the current focus of river ecology by integrating the effects of drying on the movement of aquatic and terrestrial animals. Moreover, we introduce a conceptual model that challenges the current bias, which is focused on perennial waterways, by encompassing animal movement across hydrologic phases (nonflowing, flowing, dry, rewetting) and habitats (aquatic, terrestrial). We discuss their corridor function in conservation and restoration planning and identify emerging research questions. We contend that a more comprehensive and inclusive view of animal movement in dry channels will advance ecological understanding of river networks and respective conservation efforts.more » « less

Abstract Inexpensive and accessible sensors are accelerating data acquisition in animal ecology. These technologies hold great potential for large-scale ecological understanding, but are limited by current processing approaches which inefficiently distill data into relevant information. We argue that animal ecologists can capitalize on large datasets generated by modern sensors by combining machine learning approaches with domain knowledge. Incorporating machine learning into ecological workflows could improve inputs for ecological models and lead to integrated hybrid modeling tools. This approach will require close interdisciplinary collaboration to ensure the quality of novel approaches and train a new generation of data scientists in ecology and conservation.more » « less

Seed dispersal, or the movement of diaspores away from the parent location, is a multiscale, multipartner process that depends on the interaction of plant life history with vector movement and the environment. Seed dispersal underpins many important plant ecological and evolutionary processes such as gene flow, population dynamics, range expansion, and diversity. We review exciting new directions that the field of seed dispersal ecology and evolution has taken over the past 40 years. We provide an overview of the ultimate causes of dispersal and the consequences of this important process for plant population and community dynamics. We also discuss several emergent unifying frameworks that are being used to study dispersal and describe how they can be integrated to provide a more mechanistic understanding of dispersal.more » « less

ABSTRACT Visual ecology, the study of how animals acquire and respond to visual information in nature, has grown rapidly over the past few decades. Research in this field has transformed our understanding of fundamental processes, such as the neurobiological basis of behavior and the diversification of species through sensory drive. The recent growth in the field has been accompanied by leaps in our understanding of the diversity of visual systems and in the development of novel technologies and techniques (for example, those allowing us to measure scenes and signals). With such growth, however, it is more important than ever to integrate wide perspectives and expertise to move the field forward in the most productive way. To that end, in summer 2024, 30 visual ecologists from around the world – spanning all career stages – met to discuss the state of the field. From that meeting, we identified two broad emerging themes in the study of visual ecology. (1) Can we further ‘step inside’ the perceptual experience of a non-human animal? (2) Can foundational ‘rules’ of vision and visual stimuli be identified? Although large questions such as these can feel unanswerable, this is where some of the most exciting discoveries in visual ecology remain to be made. Here, we outline eight relevant areas of research and identify ways in which researchers can bring us closer to answering these complex questions.more » « less
