Niche dynamics of alien plant species in Mediterranean Europe
Published: 2024-11-03
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Aim Humans have spread plants globally for millennia, inadvertently causing ecological disruptions. However, biological invasions also provide a unique opportunity to study the process of niche dynamics, through which species adapt their niche when confronted with novel environments. Focusing on the Mediterranean Basin, we assessed 1) which traits favour niche dynamics, and 2) whether niche [...]

Spider colour polymorphism is shaped by precipitation, not ambient temperature
Published: 2024-11-03
Subjects: Life Sciences
Colour polymorphism, the presence of multiple colour variants within a population, is a common example of intraspecific phenotypic variation and has served as a model for studying drivers of diversity. Climatic factors can influence the distribution and abundance of colour variants, yet research often focuses on lineages where sexual selection covaries with the climate-colouration associations. [...]
Continental-scale empirical evidence for relationships between fire response strategies and fire frequency
Published: 2024-11-03
Subjects: Ecology and Evolutionary Biology, Life Sciences
• Theory suggests that the dominance of resprouting and seeding, two key mechanisms through which plants persist with recurrent fire, both depend on other traits and vary with fire regime. However, these patterns remain largely untested over broad scales. • We analysed the relationships between average fire frequency, derived from MODIS satellite data, and resprouting and seeding strategies [...]
Language, economic, and gender disparities widen the scientific productivity gap
Published: 2024-11-01
Subjects: Environmental Studies
Scientific communities need to understand and eliminate barriers that prevent scientists from reaching their full potential. However, the combined impact of individuals’ linguistic, economic, and gender backgrounds on their scientific productivity is poorly understood. Using a survey of 908 environmental scientists, we show that being a woman is associated with up to a 45% reduction in the number [...]
Towards a modern and efficient European biodiversity observation network fit for multiple policies
Published: 2024-11-01
Subjects: Life Sciences
To address the biodiversity crisis, global and regional policy frameworks like the Kunming-Montreal Global Biodiversity Framework and the European Green Deal demand to monitor biodiversity. Despite these efforts, existing approaches for monitoring biodiversity remain fragmented and lack data integration. Here, we review and synthesize crucial information for developing an integrated European-wide [...]
Time will tell: the temporal and demographic contexts of plant-soil microbe interactions
Published: 2024-10-31
Subjects: Ecology and Evolutionary Biology
Soil microorganisms can have profound impacts on plant community dynamics and have received increasing attention in the context of plant-soil feedback. The effects of soil microbes on plant community dynamics are classically evaluated with a two-phase experimental design that consists of a conditioning phase, during which plants modify the soil microbial community, and a response phase, during [...]
Exploring bird biodiversity: a survey of avian richness in the dams of oke-ogun, nigeria
Published: 2024-10-30
Subjects: Life Sciences
Wetland degradation, both natural and anthropogenic, impacts biodiversity and ecosystem services. Artificial wetlands, such as dams, may help mitigate the loss of natural wetlands, but their conservation potential is understudied. This research explores avian diversity, anthropogenic impacts, and community perceptions of bird species across three dams -Igboho, Okeho, and Kishi located in [...]
Priced out of belonging? Insufficient concessions on membership fees across international societies in ecology and evolution
Published: 2024-10-30
Subjects: Ecology and Evolutionary Biology, Life Sciences
Learned societies, as professional bodies for scientists, are an integral part of the scientific system. However, their membership fees have the potential to be prohibitive to the most vulnerable members of the scientific community. To shed light on how membership fees are structured, we conducted a survey of 182 international learned societies relevant to researchers in ecology and evolution. We [...]
Overcoming Key Challenges of Satellite-based Monitoring of Ecosystem Condition: A Continental-scale Example From Australia
Published: 2024-10-30
Subjects: Life Sciences
Effective satellite-based monitoring of ecosystem integrity or condition needs to address four key challenges: (a) context dependency; (b) alternative ecological states; (c) short-term temporal ecosystem dynamics; and (d) scarcity of reference data where ecosystems retain high levels of integrity. Here we present a typology, and outline strengths and weaknesses, of different approaches to mapping [...]
Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana
Published: 2024-10-30
Subjects: Life Sciences
Climate change is accelerating deoxygenation in aquatic ecosystems worldwide, causing consequences for aerobic organisms. Empirically studying the effects of deoxygenation on biological processes is therefore critical. Multiple methods for inducing hypoxia in physiological studies have been developed, each with pros and cons. Using oxygen scavenger chemicals, such as sodium sulfite, to reliably [...]
Decadal recovery of fungal but not termite deadwood decay in tropical rainforest
Published: 2024-10-30
Subjects: Ecology and Evolutionary Biology, Life Sciences
1. Deadwood represents ~11% of carbon stocks in tropical rainforest ecosystems and its decay is driven largely by fungi and termites which contribute to the cycling of carbon and nutrients. Due to land use change, such as forest clearing, secondary growth tropical rainforests are increasingly prevalent around the globe. In secondary growth rainforest, studies found lower decay rates of leaf [...]
Reimagining species on the move across space and time
Published: 2024-10-29
Subjects: Ecology and Evolutionary Biology
Climate change is already leaving a broad footprint of impacts on biodiversity, from an individual caterpillar emerging earlier in spring to an entire plant community migrating poleward. Despite the various modes of how species are on the move, we primarily document shifting species along only one gradient (e.g., latitude or phenology) and along one dimension (space or time). Here we present a [...]
BON in a Box: An Open and Collaborative Platform for Biodiversity Monitoring, Indicator Calculation, and Reporting
Published: 2024-10-28
Subjects: Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Marine Biology, Plant Sciences
Biodiversity loss is a critical global challenge. The Kunming-Montréal Global Biodiversity Framework (GBF) sets ambitious goals to protect ecosystems, halt species loss, and enhance biodiversity. The GBF’s Monitoring Framework requires countries to track progress toward biodiversity targets using a standardized set of indicators that summarize complex trends in biodiversity. However, the [...]
Cichlid fishes are promising underutilised models to investigate helminth-microbiome interactions
Published: 2024-10-27
Subjects: Other Ecology and Evolutionary Biology, Other Microbiology, Parasitology
The “Old Friends Hypothesis” suggests that insufficient early exposure to symbionts may hinder immune development, contributing to increased immune-related diseases in the Global North. While the microbiome is often the focus, helminths, which may also offer health benefits, receive little attention. The infection and effect of helminths, in turn, are influenced and may be even determined by [...]
