Spider colour polymorphism is shaped by precipitation, not ambient temperature

Fabian C. Salgado-Roa, Devi Stuart-Fox, Iliana Medina

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

Sophie Yang, Mark KJ Ooi, Daniel S. Falster, et al.

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 [...]

Towards a modern and efficient European biodiversity observation network fit for multiple policies

W. Daniel Kissling, Tom D. Breeze, Camino Liquete, et al.

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 [...]

Exploring bird biodiversity: a survey of avian richness in the dams of oke-ogun, nigeria

Yinka Julianah Adeniji, Oluyinka Sunday Odewumi, Bibitayo Ayobami Owolabi

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

Malgorzata Lagisz, Kevin R Bairos-Novak, April Robin Martinig, et al.

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

Kristen Jennifer Williams, Simon Ferrier, Eric A Lehmann, et al.

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

Zhen Qin, Lorenzo Vassura, Bianca Allegra Parodi, et al.

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

Baptiste Joseph Wijas, Habacuc Flores-Moreno, Steven D Allison, et al.

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 [...]

BON in a Box: An Open and Collaborative Platform for Biodiversity Monitoring, Indicator Calculation, and Reporting

Jory Griffith, Jean-Michel Lord, Michael D. Catchen, et al.

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 [...]

Why do people misperceive long-term environmental change?

Catalina Munteanu, Rita Sousa-Silva, Carsten F Dormann, et al.

Published: 2024-10-25
Subjects: Life Sciences, Social and Behavioral Sciences

Environmental sciences seek to provide an unbiased quantitative and mechanistic basis for decision making, but conservation and management are often driven by personal perception of the environment. This, in turn, is made up of personal experiences, information exposure, personal values and beliefs. When documented changes in the natural world are in dissonance with people’s perceptions, [...]

Patterns of fruit production in tropical forests are shifting with negative outnumbering positive trends

Andrew Hacket-Pain, Asenath Adienge, Michał Bogdziewicz, et al.

Published: 2024-10-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Plant Sciences

The impacts of climate change and anthropogenic disturbance are increasingly evident in the structure and demographics of tropical forests, yet the response of tree reproduction remains poorly understood. As fruit and seed production is the first step in forest recruitment, this gap is critical to understanding tropical forest resilience. Tropical fruits are important in diets of numerous [...]

infinitylists: A Shiny application and R package for rapid generation of place-based species checklists

Thomas Mesaglio, Fonti Kar, Hervé Sauquet, et al.

Published: 2024-10-25
Subjects: Life Sciences

Premise: Online biodiversity databases like GBIF hold billions of occurrence records, including vouchered specimens and citizen science records. Integrating these two data streams facilitates more robust species checklists. However, processing huge biodiversity datasets can be time-consuming, and most databases are species-focused, rather than place-based, visualisation tools. Methods and [...]

Model shows abrupt loss of soil organic carbon following disturbance in seagrass ecosystems

Antoine Le Vilain, Oscar Serrano, Elisa Thébault, et al.

Published: 2024-10-23
Subjects: Life Sciences

Seagrasses are key carbon sinks in the biosphere and, hence, promising nature-based solutions for climate change mitigation. Unfortunately, they are also experiencing major anthropogenic and climatic pressures that can lead to seagrass degradation or even result in difficult-to-reverse abrupt shifts (i.e., tipping point responses) to complete loss. Although the possibility of tipping point [...]

Social justice and inclusive conservation must guide GBF implementation

James Reed, Jos Barlow, Rachel Carmenta, et al.

Published: 2024-10-21
Subjects: Life Sciences

The Kunming-Montreal Global Biodiversity Framework marked a renewed commitment to address the biodiversity crisis. This framework, consisting of four goals and 23 targets which are intended to guide conservation efforts for the next thirty years, displays an enhanced level of ambition compared to its predecessor. However, the pursuit of multilateral agreements is dependent upon national pledges, [...]
