Borealization of tundra ecosystems with climate and land-use change
Published: 2025-05-23
Subjects: Life Sciences
As the colder regions of the planet warm, species are moving northward and upward from the boreal forest to the tundra biome, a process that has been referred to as borealization. Here, we examine the diverse uses of the term borealization and propose the concept of tundra borealization for terrestrial environments to specifically describe shifts in species composition from boreal to tundra [...]
Decoding Genomic Landscapes of Introgression
Published: 2025-05-23
Subjects: Life Sciences
Genomic landscapes of introgression provide valuable information for how different evolutionary processes interact and leave signatures in genomes. The recent expansion of genomic datasets across diverse taxa, together with advances in methodological development, has created new opportunities to investigate the impact of introgression along individual genomes in various clades, making the precise [...]
Neighborhood habitat gains increase plant species richness in forest fragments
Published: 2025-05-23
Subjects: Life Sciences
Theory and indirect evidence suggest that when new habitat is added to a habitat fragment’s local landscape, or “neighborhood”, species richness in the fragment will increase. Although this hypothesis is frequently assumed, it has not yet been tested directly with longitudinal data. In a natural forest regeneration experiment on Aotearoa New Zealand’s South Island, we use causal inference to show [...]
Ocean warming drives abrupt declines in fish productivity at global scale
Published: 2025-05-22
Subjects: Life Sciences
Marine life is under multiple pressures, including climate change and overfishing. Environmental change and variability can threaten fishery sustainability, especially when it results in large, abrupt and persistent shifts in productivity of fish stocks. Reports of abrupt shifts in marine systems are not uncommon, but a global assessment of their occurrence and drivers is seriously lacking. Here, [...]
IUCN Red List of Ecosystems. Sandy Beaches & Dunes of the Gulf of Guinea North
Published: 2025-05-22
Subjects: Life Sciences
The sandy beaches and dunes of the Gulf of Guinea North is a regional ecosystem subgroup along the West African coast. It had a mapped extent of 256 km² in 2022, with a width ranging from of 0.01 km to 1.02 km, and stretches over approximately 2481 km. This ecosystem subgroup extends along the shores of Benin, Togo, Ghana, Côte d'Ivoire, Liberia, Sierra Leone, Guinea and Guinea Bissau. This [...]
IUCN Red List of Ecosystems. Sandy Beaches & Dunes of the West African Transition
Published: 2025-05-22
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences
Abstract The ‘Sandy Beaches and Dunes of the West African Transition’ form a regional ecosystem subgroup along the West African coast. It had a mapped extent of 584 km² in 2022, with a width ranging from 0.012 km to 4.796 km, and stretching over approximately 1321 km. This ecosystem subgroup extends along the shores of Mauritania, The Gambia and Senegal. This ecosystem frequently experiences [...]
Revisiting the copepod diversity of Indian Sundarbans through estimation of carcasses
Published: 2025-05-21
Subjects: Life Sciences
Diversity assessment of plankton traditionally considers species richness and abundance, overlooking the vital state of individuals (i.e., alive or dead). This study aimed to integrate the vital state of zooplankters into diversity indices, using the copepods of the Indian Sundarbans (IS) as an example community. It was hypothesized that when carcasses estimation (CE) is incorporated diversity [...]
Filling Monitoring Gaps for Data-deficient Species Using Annual Occupancy Predictions from Co-occurrence Models
Published: 2025-05-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
Fragmented surveys and limited monitoring exclude most invertebrate species from conservation policy. We present a framework that generates annual occupancy predictions using species distribution models (SDMs) to reconstruct missing trends—not to extrapolate trends, but to fill them in (the fill-in approach). Instead of filtering poor-data regions and years or relying on static environmental [...]
NextGeneration specimen digitization: The international herbarium community goes spectral!
Published: 2025-05-20
Subjects: Life Sciences
1. Spectral reflectance measured from herbarium specimens represents a vast source of plant phenotypic and functional trait data. 2. The potential to capture data from specimens to enhance knowledge of plant function and taxon identification has inspired many laboratories worldwide to initiate next-generation spectral digitization from specimens. 3. Combining these datasets into a coordinated [...]
Multimodal data integration to model, predict, and understand changes in plant biodiversity: a systematic review
Published: 2025-05-16
Subjects: Life Sciences
The integration of multimodal data to analyze, model, and predict changes in plant biodiversity is critical for addressing global conservation challenges. This systematic review examines the current landscape of plant biodiversity data, focusing on the identification, classification, and evaluation of key open-access data sources and integration methodologies. We highlight the strengths and [...]
Nestbox use is linked to increased paternity loss in infected blue tits, but not great tits
Published: 2025-05-16
Subjects: Life Sciences
Host-parasite interactions and reproductive strategies are critical aspects of avian life history, yet knowledge of their interplay in the context of nesting site microhabitat, in particular between natural and artificial nesting sites, is lacking. The choice of nesting site is critical for successful breeding, by ensuring protection from predators and a suitable environment for incubation and [...]
Disordered and Partially Structured Models in Community Ecology: What are they? And how do we use them?
Published: 2025-05-15
Subjects: Life Sciences, Physical Sciences and Mathematics
Community ecology describes how species interact with each other and with their environment. In nature, processes can be very complex because they involve hundreds to thousands of species interacting with each other in complex environmental landscapes. Classical approaches that have provided key insights have largely focused on the study of tractable subsets of species and patches, but these do [...]
The burden of a failed error culture in biologging
Published: 2025-05-15
Subjects: Ecology and Evolutionary Biology, Life Sciences
Driven by technological advancements and reduced costs, biologging has seen a rapid growth transforming the study of animal behaviour and ecology. This ``golden era'' of animal tracking provides unprecedented insights into wildlife, aiding conservation efforts and ecological research. However, in the wake of the rapid growth loom pressing ethical and methodological challenges, including a lack of [...]
Transgenerational plasticity to warming decreases nutrient release by a keystone grazer
Published: 2025-05-15
Subjects: Life Sciences
Increasing temperatures as a result of global climate change can alter the physiology of organisms via selection for tolerant genotypes and individual-level plasticity. Organisms experiencing thermal stress can not only modify their own physiological expression, but also those of future generations; i.e. transgenerational plasticity (TGP). While warming triggered TGP is well documented, its [...]
Invisible but Identifiable: p-Chips as a Reliable Marking Method for Amazonian Bats
Published: 2025-05-14
Subjects: Life Sciences
Marking techniques are essential for studying bat ecology and informing conservation efforts, yet many existing methods present challenges related to size, tag detectability, and long-term retention. P-Chips, ultra-miniaturized transponders detectable via red laser light, offer a promising alternative to traditional banding or passive integrated transponer (PIT) tags. While their use has been [...]
