HeliCat Canada’s Wildlife Observations Program: Trends and Findings 2012-2022
Published: 2023-06-30
Subjects: Natural Resources and Conservation
HeliCat Canada members operating in mountain caribou range have been collecting and reporting wildlife sightings data since 2010, resulting in more than 3,750 spatially referenced sightings of animals and tracks by the end of the 2022 operating season. Mountain caribou, mountain goats, and wolverine have been the most commonly recorded species, with caribou observations generally declining over [...]
Lipid Metabolism in Parasitoids and Parasitized Hosts
Published: 2023-06-30
Subjects: Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Physiology
Parasitoids have an exceptional lifestyle where juvenile development is spent on or in a single host insect, but the adults are free-living. Unlike parasites, parasitoids kill the host. How parasitoids use such a limiting resource, particularly lipids, can affect chances to survive and reproduce. In part 1, we describe the parasitoid lifestyle, including typical developmental strategies. Lipid [...]
A call to expand global change research in LTER coastal wetlands
Published: 2023-06-30
Subjects: Ecology and Evolutionary Biology
Global change stressors are altering the structure of ecological communities with significant implications for the functions and services that ecosystems provide. Coastal zones are particularly susceptible to such stressors, yet our collective understanding of the long-term effects of global change on these systems and, in particular, the consumer species found within them, is limited. The US [...]
Shall we all adopt, with no worries, the ‘within a configuration’ approach in geometric morphometrics? A comment on claims that the effect of the superimposition and sliding on shape data is “not an obstacle to analyses of integration and modularity”
Published: 2023-06-30
Subjects: Life Sciences
The study of modularity and integration using Procrustes geometric morphometrics has become a prominent approach in evolutionary developmental biology. A most popular method is the ‘within a configuration’ approach, often used in combination with ‘high density’ morphometric data (i.e., large numbers of landmarks and semilandmarks). In 2019, I realized that this approach violates a basic [...]
Camtrap DP: An open standard for the FAIR exchange and archiving of camera trap data
Published: 2023-06-30
Subjects: Behavior and Ethology, Biodiversity, Population Biology
Camera trapping has revolutionized wildlife ecology and conservation by providing automated data acquisition, leading to the accumulation of massive amounts of camera trap data worldwide. Although management and processing of camera trap-derived Big Data are becoming increasingly solvable with the help of scalable cyber-infrastructures, harmonization and exchange of the data remain limited, [...]
Unleashing the Potential of Artificial Reefs Design: A Purpose-Driven Evaluation of Structural Complexity
Published: 2023-06-30
Subjects: Engineering
Artificial reefs (AR) must be built according to their objective and show high complexity to mimic the characteristic of natural habitats. To enhance the integration of artificial structures into ecosystems, a new quantitative method has been developed to evaluate their complexity, using 3D computer-aided design (CAD) models of ARs. The method utilizes six metrics: three related to geometric [...]
Adaptive parsimony as an evolutionary solution to the equilibrium selection problem
Published: 2023-06-29
Subjects: Social and Behavioral Sciences
Many games, especially repeated games, have multiple Nash equilibria, which limits the predictive power of game theory for understanding animal behavior. In this article, I propose a solution to this problem inspired by the notion of stability by convergence from adaptive dynamics. The multiplicity of equilibria is due to the possibility of strategies that are arbitrary in the sense that they are [...]
Seascape genomics: assisting marine biodiversity management by combining genetic knowledge with environmental and ecological information
Published: 2023-06-24
Subjects: Life Sciences
Biodiversity, including genetic diversity, is the foundation of ecosystems and the well-being of all organisms, including humans. Determining how the marine environment shapes genetic diversity and developing best practices to conserve it requires a multi-disciplinary approach incorporating genomic and environmental information. Seascape genetics and genomics combine spatially resolved [...]
Too simple, too complex, or just right? Advantages, challenges and resolutions for indicators of genetic diversity
Published: 2023-06-23
Subjects: Ecology and Evolutionary Biology, Environmental Policy, Genetics, Life Sciences
Measuring genetic diversity of wild species using DNA-based data remains resource intensive and time-consuming for nearly all species. Yet, genetic assessments are needed for global conservation commitments including the Convention on Biological Diversity and for governments and managers to evaluate conservation progress and to prioritize species and populations to preserve and recover genetic [...]

Heterogeneous dispersal networks to improve biodiversity science
Published: 2023-06-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology
Dispersal plays a key role in shaping spatial patterns of biodiversity, yet its spatial heterogeneity is often overlooked in biodiversity analyses and management strategies. Properly parametrized heterogeneous dispersal networks capture the complex interplay between landscape structure and species-specific dispersal capacities. This heterogeneity, however, is recurrently neglected when studying [...]
Landscape changes in the “valli da pesca” of the Venice lagoon and possible effects on the Ecosystem Services supply
Published: 2023-06-21
Subjects: Environmental Monitoring, Environmental Sciences, Environmental Studies, Natural Resources and Conservation, Nature and Society Relations, Other Environmental Sciences, Remote Sensing, Sustainability, Terrestrial and Aquatic Ecology
Coastal lagoons have long been subject to continuous changes caused by mutual interactions with human activities. Monitoring such changes becomes critical, particularly when modifications in landscape and land cover classes can affect their capacity to ensure Ecosystem Services (ESs). In the Venice lagoon, some confined areas called “valli da pesca” supply provisioning ESs, namely aquaculture and [...]
Community-based conservation and restoration in coastal wetlands: A review
Published: 2023-06-19
Subjects: Natural Resources and Conservation, Natural Resources Management and Policy
Research has shown that conservation and restoration efforts that engage local communities are more successful at meeting stated goals than those that are externally controlled. Such participatory management approaches have been increasingly applied in coastal wetland ecosystems, yet our collective understanding of the scope of methods applied and outcomes observed in these efforts is limited. In [...]
Griffon Vultures restrict movements around roosts and supplementary feeding stations, even when carrion is available on the field: a call for wind energy zonation to avoid ecological traps on Mediterranean islands
Published: 2023-06-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Environmental Engineering
Wind energy is developing on Mediterranean islands, where endangered populations of Griffon Vulture (Gyps fulvus) occur. As griffons are subjected to collisions with wind turbines while foraging, it is necessary to understand which factors affect their movements, to minimize the potential impact of wind farms. We assessed habitat use by 37 griffons (n. GPS locations = 130,218) and its overlap [...]
Hypotheses on the extended phenotype of the mitochondrion: sex, mortality, and aging
Published: 2023-06-19
Subjects: Biology, Evolution
How did sex evolve, how is sex evolutionary stable, and why do eukaryotes appear mortal. This paper presents a mitochondrial perspective on the evolution of the eukaryotic cell that appears capable of answering these questions. Rather than viewing a mitochondrion as a passive entity taken up by an archaeal host that remains in the driving seat, mitochondria are viewed as the key force [...]
