Life history shapes variation in egg composition in the blue tit Cyanistes caeruleus
Published: 2024-09-11
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Maternal investment directly shapes early developmental conditions and therefore has long-term fitness consequences for the offspring. In oviparous species prenatal maternal investment is fixed at the time of laying. To ensure the best survival chances for most of their offspring, females must equip their eggs with the resources required to perform well under various circumstances, yet the actual [...]
Adaptive sampling for ecological monitoring using biased data: A stratum-based approach
Published: 2024-09-10
Subjects: Applied Statistics, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Indicators of biodiversity change across large extents of geographic, temporal and taxonomic space are frequent products of various types of ecological monitoring and other data collection efforts. Unfortunately, many such indicators are based on data that are highly unlikely to be representative of the intended statistical populations. Where there is full control over sampling processes, [...]
Harnessing social media data to track species range shifts
Published: 2024-09-10
Subjects: Biodiversity, Life Sciences
Biodiversity monitoring programs and citizen science data remain heavily biased towards the Global North. Incorporating social media data can complement existing gaps, especially in megadiverse countries with limited records, but whether such data can significantly improve our understanding of range-shifting species is unknown. Here, we collated locality data from Flickr and Facebook, in addition [...]
The evolution of sex ratio strategies in cooperative breeders
Published: 2024-09-09
Subjects: Life Sciences
1. The offspring sex ratio is often biased in cooperative breeders. Two hypotheses explain why this could be adaptive: 1) the local resource enhancement hypothesis, and 2) the local resource competition hypothesis. The first poses that offspring of the helping sex should be overproduced, as helpers provide fitness benefits to parents and future siblings. The second poses that offspring of the [...]
Climate change is associated with a higher extinction risk of a subshrub in anthropogenic landscapes
Published: 2024-09-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
In most ecosystems, the increasingly strong effects of climate change on biodiversity co-occur with other anthropogenic pressures, most importantly land-use change. However, many long-term demographic studies focus on populations monitored in protected areas, and our understanding of how climate change will affect population persistence under anthropogenic land use is still limited. To fill this [...]
Molecular plasticity contributes to thermal resilience in two coastal fish species
Published: 2024-09-03
Subjects: Life Sciences, Zoology
Understanding species capacities to adjust to shifting thermal environments is crucial amidst current climate-mediated ocean warming. Fish populations displaying high thermal plasticity can undergo molecular, metabolic, and mitochondrial modifications in response to heat stress. Under the context of heat stress, such acclimation provides a means to maintain normal biological functions through [...]
Evidence of the Impacts of Pharmaceuticals on Aquatic Animal Behaviour (EIPAAB): a systematic map and open access database
Published: 2024-09-03
Subjects: Life Sciences
BackgroundOver the last decade, pharmaceutical pollution in aquatic ecosystems has emerged as a pressing environmental issue. Recent years have also seen a surge in scientific interest in the use of behavioural endpoints in chemical risk assessment and regulatory activities, underscoring their importance for fitness and survival. In this respect, data on how pharmaceuticals alter the behaviour of [...]
Genetic adaptation to climate change in wild populations: a systematic literature review identifies opportunities to strengthen our evidence base
Published: 2024-09-02
Subjects: Life Sciences
To understand to what extent evolution can contribute to bending the curve of ongoing biodiversity losses, we urgently need to characterize the adaptive potential of populations. This systematic literature review comprehensively gathers existing examples of genetic adaptation to climate change to (1) guide efforts to assess genetic adaptation to climate change in a wider variety of species and [...]
The role of forests in global climate adaptation
Published: 2024-09-02
Subjects: Life Sciences
Forests play a crucial role in regulating the global climate. Yet, forests also influence the local climate conditions through biophysical processes that directly impact human wellbeing. With growing policy emphasis on these climate adaptation effects, we review the scale dependent impacts of forests on climate conditions and their implications for human wellbeing. Generally, existing forests [...]
Fear of supernatural punishment can harmonize human societies with nature: an evolutionary game-theoretic approach
Published: 2024-09-02
Subjects: Life Sciences
Human activities largely impact the natural environment negatively and radical changes in human societies would be required to achieve their sustainable relationship with nature. Although frequently overlooked, previous studies have suggested that supernatural beliefs can protect nature from human overexploitation via beliefs that supernatural entities punish people who harm nature. Studies of [...]
Quantifying Carbon Sequestration and Ecosystem Enhancement Through Novel Phytoplankton Farming Techniques
Published: 2024-08-28
Subjects: Ecology and Evolutionary Biology, Life Sciences
Phytoplankton farming emerges as a critical nature-based solution to address the intertwined crises of climate change and marine ecosystem degradation. As foundational drivers of oceanic carbon cycling, phytoplankton generate ~50% of Earth’s oxygen and sequester 10–20 billion metric tons of CO₂ annually through the biological carbon pump . This study develops scalable cultivation techniques to [...]
Rethinking Environmental Impact Assessment for nature positive development
Published: 2024-08-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Achieving nature positive development within existing regulatory frameworks will be challenging. Halting and reversing biodiversity loss requires restoration and enhancement of ecosystems alongside a fundamental shift in how we value biodiversity and assess quantifiable improvements. Environmental Impact Assessments (EIAs) focussed on mitigating negative impacts do not promote positive outcomes – [...]
Let’s DAG in – How DAGs can help Behavioural Ecology be more transparent
Published: 2024-08-27
Subjects: Life Sciences
Directed acyclic graphs (DAGs) are powerful tools for visualizing assumptions/hypothesis and causal inference. Although their use is becoming more widespread across various disciplines, they remain underutilized in behavioural ecology and evolution. Here, we point out why DAGs can serve as highly valuable tools in this field, particularly in the context of observational and field studies, which [...]
Quantifying disturbance effects on ecosystem services in a changing climate
Published: 2024-08-27
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Disturbances, such as hurricanes, fires, droughts, and pest outbreaks, can cause major changes in ecosystem conditions that threaten nature’s contributions to people (ecosystem services). However, approaches to assess these impacts on diverse services under climate change are rare. To advance such efforts, we build on the accelerating research on disturbance ecology and ecosystem services to [...]
Navigating the complexities of “One Health”
Published: 2024-08-27
Subjects: Life Sciences
For two decades, a One Health approach to managing the emergence of novel zoonotic pathogens has been increasingly called for by the animal and public health sectors. One health systems require the integration of data from wildlife indicator species, domesticated animals, and humans into a framework of monitoring and analysis that provides for early warning of impending pathogen spillover and [...]
