A toolbox to quantify human activity in protected areas for park management
Published: 2024-08-26
Subjects: Biodiversity
1. Recreation in protected areas (PAs) is growing worldwide, potentially conflicting with wildlife and ecosystem protection. Efficiently estimating human activity in PAs is crucial for balancing a dual mandate of supporting visitor access and biodiversity, but managers lack clear recommendations about how best to monitor spatial and temporal trends in human activity. 2. Through two case [...]
Current knowledge on the novel semiarid photovoltaic ecosystems and their impacts on biodiversity
Published: 2024-08-26
Subjects: Biodiversity, Life Sciences, Terrestrial and Aquatic Ecology
The transition from fossil fuels to renewable energy sources is fundamental to mitigate the effects of global climate change. Renewable power capacity is increasing globally, and solar photovoltaic will be the dominant renewable energy source by 2050. Photovoltaic parks require great extensions of land, usually in drylands. But both ecosystems created by solar parks and the effect of solar parks [...]
Dormancy in the origin, evolution, and persistence of life on Earth
Published: 2024-08-26
Subjects: Life Sciences
Life has existed on Earth for most of the planet's history, yet major gaps and unresolved questions remain about how it first arose and persisted. Early Earth posed numerous challenges, including harsh, noisy, and fluctuating environments. Today, many organisms cope with such conditions by entering a reversible state of reduced metabolic activity, a phenomenon known as dormancy. This process [...]
PPSDB : A Linked Open Data knowledge base for protist-prokaryote symbiotic interactions
Published: 2024-08-26
Subjects: Biodiversity, Environmental Microbiology and Microbial Ecology Life Sciences
As the ecological and evolutionary importance of symbiotic interactions between protists (microbial eukaryotes) and prokaryotes (bacteria and archaea) is better appreciated, keeping an overview of their diversity and the literature becomes a growing and ongoing challenge. Here we present the Protist-Prokaryote Symbiosis Database (PPSDB), comprising 789 manually curated interaction statements [...]
A top predator provokes similar defense behavior as a mesopredator in an intraguild prey
Published: 2024-08-26
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Ornithology
The loss of top predators has been shown to lead to drastic changes in community structure. An important part of this is the shift in behavior of other species. The understanding of such changes is scarce because recordings of behavioral reactions towards lost species are rarely done. This is important for predators experiencing predation pressure themselves, known as intraguild predation. [...]
Multilevel societies: different tasks at different social levels
Published: 2024-08-26
Subjects: Life Sciences
Multilevel vertebrate societies, characterised by nested social units, allow individuals to perform a wide range of tasks in cooperation with others beyond their core social unit. In these societies, individuals can selectively interact with specific partners from higher social levels to cooperatively perform distinct tasks. Alternatively, social units of the same level can merge to form [...]
Reversing the North American bumblebee decline: Looking at farming practices could be a solution
Published: 2024-08-26
Subjects: Life Sciences
Wild bee declines have been documented worldwide, particularly in bumblebees, with some species in Nort America declining over 90% in the last 20 years. Climate change, land-use change from agriculture, pesticide use, and apiculture are the main drivers. The 2.2-hectare farm La ferme de l’Aube is the research site of a larger 3,082-hectare biodiversity reserve. The study area saw a 340% increase [...]
60 million years of ecological shifts in large herbivore communities revealed by Network Analysis
Published: 2024-08-17
Subjects: Life Sciences
The fossil record provides direct evidence for the behavior of biological systems over millions of years. In doing so, paleontological information becomes a key source to study the evolution of ecosystems and how they responded to major environmental shifts. Using network analysis over a dataset of worldwide large herbivores spanning the past 60 Myr, we found that large herbivore assemblages [...]
Phylogeny of Weinmannia (Cunoniaceae) reveals the Contribution of the Southern Extratropics to Tropical Andean Biodiversity.
Published: 2024-08-17
Subjects: Life Sciences
The Andes are a relatively young mountain range with impressive biodiversity, but the biogeographic processes underlying its hyperdiversity are still being unraveled. Novel mid- to high-elevation climates may have served as a biological corridor for the immigration of temperate-adapted lineages to lower latitudes, contributing unknown levels of diversity to this region. We tested the hypothesis [...]
IUCN Red List of Ecosystems, Mangroves of The Western India and Pakistan
Published: 2024-08-13
Subjects: Life Sciences
Mangroves of the Western India and Pakistan is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of Western India and Pakistan. According to global data the Western India and Pakistan mangrove province mapped extent in 2020 was 1625.3 km2, representing 1.1% of the global mangrove area, while national and regional studies [...]
IUCN Red List of Ecosystems, Mangroves of the Tropical Southwestern Pacific
Published: 2024-08-13
Subjects: Ecology and Evolutionary Biology, Life Sciences
Mangroves of the Tropical Southwestern Pacific are a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of Central and Southern Great Barrier Reef, Coral Sea, Fiji Islands, New Caledonia, Tonga Islands, Torres Strait Northern Great Barrier Reef, and Vanuatu. The Tropical Southwestern Pacific province mapped extent in 2020 was 874.0 [...]
Meiotic drive and genome evolution in vascular land plants
Published: 2024-08-13
Subjects: Life Sciences
Meiotic drive is a deviation from Mendelian inheritance where genetic elements are preferentially inherited by the surviving egg cell. This can profoundly impact chromosome (and genome) size and structure. Across vascular plants, heterosporous lineages typically have fewer chromosomes than homosporous lineages. The underlying mechanism causing this disparity has been debated for over half a [...]
Evaluating drivers and predictability of catch composition in a highly mixed trawl fishery using stacked and joint species models
Published: 2024-08-13
Subjects: Life Sciences
Evaluating drivers and the predictability of catch is valuable for the management of mixed fisheries. Drivers can represent or help to identify levers for management and predictable catch compositions are a key component of simulation tools and dynamic management strategies. But modelling mixed fisheries can be challenging due to the large number of taxa, and analysis typically focuses on a few [...]
The macroecology of knowledge: Spatio-temporal patterns of name-bearing types in biodiversity science
Published: 2024-08-12
Subjects: Biodiversity, Life Sciences
Ecological and evolutionary processes are recognized as the main factors generating and maintaining biodiversity. However, how biodiversity knowledge is collated, organized, and distributed worldwide influences our perceptions and inferences about biodiversity and the underlying processes. We demonstrated that name-bearing type specimens (NBT), the most fundamental reference for the identity of [...]
No support for honest signalling of male quality in zebra finch song
Published: 2024-08-12
Subjects: Behavior and Ethology, Evolution, Life Sciences, Ornithology
Alam et al.1 claim to have discovered a song feature, called “path length”, that honestly signals male fitness and is therefore preferred by all females. We see no statistical support for this claim in the original data. (1) The main finding about path length being an honest signal of quality (Fig. 4c) results from a statistical artefact, the regression of y minus x over x, which creates an [...]
