Survival patterns and population stability of cliff plants suggest high resistance to environmental variability
Published: 2024-02-10
Subjects: Biodiversity, Ecology and Evolutionary Biology
Cliffs are marginal and poorly studied habitats that are home to a high proportion of endemic or threatened species. Here, we review the survival patterns and population dynamics of plants growing on vertical cliffs and compare them to other plants with similar life histories that grow on the ground. To this end, we have compiled studies of cliff and ground plants from two main sources: MONITO [...]
Ten Simple Rules to build a Model Life Cycle
Published: 2024-02-09
Subjects: Bioinformatics, Ecology and Evolutionary Biology, Software Engineering
Just like data, models have their own life cycle. By recognizing how one’s model fits within the life cycle of the data (or at least, ensuring that the model life cycle is understood), we can identify opportunities to foster new collaborations, encourage better practices in data analysis, and ultimately accelerate research. In this manuscript, we introduce the Model Life Cycle and develop a [...]
Global exposure risk of frogs to increasing environmental dryness
Published: 2024-02-08
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Zoology
Compared with the risks associated with climate warming and extremes, the risks of climate-induced drying to animal species remain understudied. This is particularly true for water-sensitive groups, such as anurans (frogs and toads), whose long-term survival must be considered in the context of both environmental changes and species sensitivity. Here, we mapped global areas where anurans will [...]
Large-scale spatio-temporal variation in vital rates and population dynamics of an alpine bird
Published: 2024-02-02
Subjects: Applied Statistics, Ecology and Evolutionary Biology, Population Biology, Statistical Models
Quantifying temporal and spatial variation in animal population size and demography is a central theme in ecological research and important for directing management and policy. However, this requires field sampling at large spatial extents and over long periods of time, which is not only prohibitively costly but often politically untenable. Participatory monitoring programs (also called citizen [...]
What is the evidence that counter-wildlife crime interventions are effective for conserving African, Asian, and Latin American wildlife directly threatened by exploitation? A Systematic Map
Published: 2024-02-01
Subjects: Ecology and Evolutionary Biology
1. Counter-wildlife crime interventions ̶ those that directly protect target wildlife from illegal harvest/persecution, detect and sanction rule-breakers, and interdict and control illegal wildlife commodities ̶ are widely applied to address biodiversity loss. This systematic map provides an overview of the literature on the effectiveness of counter-wildlife crime interventions for conserving [...]
How bottlenecks shape adaptive potential: from theory and microbiology to conservation biology
Published: 2024-02-01
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Wild populations frequently undergo demographic changes that can destabilize their persistence and, thus, the equilibrium of ecosystems. For instance, habitat loss due to human activities leads to a drastic population size reduction, a process called a bottleneck. By reducing genetic diversity, a bottleneck may prevent a population from adapting to subsequent environmental changes. In the context [...]
The relative contribution of acoustic signals versus movement cues in group coordination and collective decision-making
Published: 2024-01-31
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
To benefit from group living, individuals need to maintain cohesion and coordinate their activities. Effective communication thus becomes critical, facilitating rapid coordination of behaviours and reducing consensus costs when group members have differing needs and information. In many bird and mammal species, collective decisions rely on acoustic signals in some contexts but on movement cues in [...]
The Distraction Function of Extrafloral Nectaries: Keeping Ants Away From Flowers and Preventing Disruption of Pollination
Published: 2024-01-31
Subjects: Desert Ecology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
In exchange for extrafloral nectar, ants deter herbivores from the plants, reducing the amount of herbivory they suffered. However, this defensive mutualism can sometimes have negative effects on plants, as ants may also visit flowers, deterring pollinators and reducing plant fitness. The Distraction Hypothesis posits that extrafloral nectaries (EFNs) have the function of attracting ants and [...]
Comparing conservation land acquisition strategies using agent-based models
Published: 2024-01-30
Subjects: Biodiversity, Ecology and Evolutionary Biology
Most unprotected biodiversity is found outside state-owned protected areas, so developing effective conservation initiatives on privately and communally-owned land is critical. Conservationists have a long history of working with these landowners and their actions can be divided into two broad categories. The first is where they agree to take over responsibility for management, either by buying [...]
Experimental protocol for validation of Computational Fluid Dynamics palaeoecological simulations
Published: 2024-01-30
Subjects: Ecology and Evolutionary Biology, Life Sciences
Computational Fluid Dynamics (CFD) simulations are increasingly used to test palaeoecological hypotheses. These analyses output simulated velocity and pressure flow profiles, and drag and lift force values acting on a model. These outputs are presumed to be internally consistent, assuming consistently applied parameters, but it is unclear whether these reflect real-world force measurements. [...]
The fossil record of the Neogene Carnivore Mammals from Spain
Published: 2024-01-25
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Carnivore mammals (Carnivora, Mammalia) constitute a significant component of the Spanish Neogene faunas, not so much due to their fossil abundance, which is generally low, but rather because of their high degree of taxonomic diversity. We assessed their evolutionary dynamics from the fossil record of Iberian carnivores using per-taxon rates of origination, extinctions and turnover combined with [...]
Hybridization potential of brown trout, with particular reference to invaded environments
Published: 2024-01-25
Subjects: Aquaculture and Fisheries Life Sciences, Biodiversity, Ecology and Evolutionary Biology, Evolution, Life Sciences, Marine Biology, Population Biology
Hybridization is a complex process beginning with the mating of two species. However, hybrid offspring frequency does not predict hetero-specific mating frequency, as post-mating, both pre-zygotic and post-zygotic barriers influence their occurrence. Post-zygotic outbreeding depression usually results in poor embryo-juvenile survival or the production of sterile hybrid offspring. Females have [...]
Quantifying soil microbial effects on plant species coexistence: a conceptual synthesis
Published: 2024-01-25
Subjects: Ecology and Evolutionary Biology
Soil microorganisms play a critical role in shaping the biodiversity dynamics of plant communities. These microbial effects can arise through direct mediation of plant fitness by pathogens and mutualists, and over the past two decades, numerous studies have shined a spotlight on the role of dynamic feedbacks between plants and soil microorganisms as key determinants of plant species coexistence. [...]
Puma space use and dispersal in tropical biodiversity hotspots: bridging a gap to connect individuals to populations
Published: 2024-01-25
Subjects: Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Zoology
Assessing residency and dispersal behavior of apex predators and its consequences for landscape connectivity is of paramount importance for understanding population- and ecosystem- effects of anthropogenic land use change. However, basic information on animal space use is still lacking, particularly in the Tropics. Here we synthesize ranging and dispersal ecological information on pumas (Puma [...]
Predicting organismal response to marine heatwaves using mechanistic thermal landscape models
Published: 2024-01-23
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology
Marine heatwaves (MHWs) can cause thermal stress in marine ectotherms, experienced as a pulse against the press of anthropogenic warming. When thermal stress exceeds organismal capacity to maintain homeostasis, organism survival becomes time-limited and can result in mass mortality events. Current methods of detecting and categorizing MHWs rely on statistical analysis of historic climatology, and [...]
