Faunal turnover in Indo-Australia across Wallace's Line is one of the most recognizable patterns biogeography and has catalyzed debate about role evolutionary geoclimatic history biotic interchanges. Here, analysis more than 20,000 vertebrate species with a model geoclimate biological diversification shows that broad precipitation tolerance dispersal ability were key for exchange deep-time gradient spanning region. Sundanian (Southeast Asian) lineages evolved climate similar to humid "stepping stones" Wallacea, facilitating colonization Sahulian (Australian) continental shelf. By contrast, predominantly drier conditions, hampering establishment Sunda shaping faunal distinctiveness. We demonstrate how adaptation past environmental conditions shapes asymmetrical global biogeographic structure.

The macro-eco-evolutionary interplay between dispersal, competition and landscape structure in generating biodiversity

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2024, Номер 379(1907)

Theory links dispersal and diversity, predicting the highest diversity at intermediate levels. However, modulation of this relationship by macro-eco-evolutionary mechanisms competition within a landscape is still elusive. We examine interplay between dispersal, structure in shaping biodiversity over 5 million years dynamic archipelago landscape. model allopatric speciation, temperature niche, competition, trait evolution trade-offs competitive traits. Depending on abilities their interaction with structure, our exhibits two ‘connectivity regimes’, that foster speciation events among same group islands. Peaks (i.e. alpha, gamma phylogenetic), occurred dispersal; while shifted peaks towards higher values for each connectivity regime. This shift demonstrates how can boost through thermal specialists, ultimately limiting geographical ranges. Even simple landscape, multiple relationships emerged, all shaped similarly according to strength. Our findings remain valid as dispersal- competitive-related traits evolve trade-off; potentially leaving identifiable signatures, particularly when are imposed. Overall, we scrutinize convoluted species interactions processes, lasting imprints biodiversity. article part theme issue ‘Diversity-dependence dispersal: interspecific determine spatial dynamics’.

ABSTRACT Aim We investigated the biogeographical patterns of a widespread arboreal lizard found throughout Wallacea and western Pacific islands. contains longstanding oceanic currents that flow from Ocean into Indian Ocean, known as Indonesian Throughflow. Using genetic data, we aim to estimate timing sequence island colonisation in Lesser Sunda archipelago southern Wallacea, determine proportion dispersal events may have been aided by ocean currents. Levels gene are also explored context arrangement, past connectivity (ex. Pleistocene land bridges), Location Southern (Indonesia, Timor‐Leste). Taxon Emerald Tree Skink ( Lamprolepis smaragdina ).

Island geography drives evolution of rattan palms in tropical Asian rainforests

Science, Год журнала: 2025, Номер 387(6739), С. 1204 - 1209

Distributed across two continents and thousands of islands, the Asian tropics are among most species-rich areas on Earth. The origins this diversity, however, remain poorly understood. Here, we reveal classify contributions individual tropical regions to their overall diversity by leveraging species-level phylogenomic data new fossils from palm lineage, rattans relatives (Arecaceae, Calamoideae). Radiators (Borneo) generate distribute incubators (Indochina, New Guinea, Sulawesi) produce in isolation, corridors (Java, Maluku, Sumatra, Thai-Malay Peninsula) connect neighboring regions, accumulators (Australia, India, Palawan, Philippines) acquire generated elsewhere. These contrasting can be explained differences region size elucidating how unique island-dominated geography drives outstanding biodiversity.

Future climate warming threatens coral reef function on World Heritage reefs

Abstract Climate change is the most significant threat to natural World Heritage (WH) sites, especially in oceans. Warming has devastated marine faunas, including reef corals, kelp, and seagrass. Here, we project future declines species ecosystem functions across Australia's four WH coral regions. Model simulations estimating species‐level abundances probabilities of ecological persistence were combined with trait space reconstructions at “present,” 2050 (+1.5°C warming), 2100 (+2°C) explore biogeographical overlaps identify key functional differences forecast changes function through time. Future climates varied by region, Shark Bay projected warm (>1.29°C), followed Lord Howe, when standardized park size.

Novel phylogenomic inference and ‘Out of Asia’ biogeography of cobras, coral snakes and their allies

Royal Society Open Science, Год журнала: 2024, Номер 11(8)

Опубликована: Авг. 1, 2024

Estimation of evolutionary relationships among lineages that rapidly diversified can be challenging, and, in such instances, inaccurate or unresolved phylogenetic estimates lead to erroneous conclusions regarding historical geographical ranges lineages. One example underscoring this issue has been the challenge posed by untangling biogeographic origin elapoid snakes, which includes numerous dangerously venomous species as well not known dangerous humans. The worldwide distribution lineage makes it an ideal group for testing hypotheses related faunal exchanges many continents and other landmasses occupied contemporary species. We developed a novel suite genomic resources, included sampling, inferred robust estimate relationships, we leveraged quantitatively range evolution through deep-time history remarkable radiation. Our biogeographical definitively reject lingering former ‘Out Africa’ hypothesis support Asia’ scenario involving multiple between Asia, Africa, Australasia, Americas Europe.

Deep biogeographic barriers explain divergent global vertebrate communities

Nature Communications, Год журнала: 2024, Номер 15(1)

Abstract Biogeographic history can lead to variation in biodiversity across regions, but it remains unclear how the degree of biogeographic isolation among communities may differences biodiversity. analyses generally treat regions as discrete units, species assemblages differ much they share, just evolutionary share. Here, we use a continuous measure distance, phylobetadiversity, analyze influence on taxonomic and functional diversity global mammal bird assemblages. On average, is better predicted by environment than isolation, especially for birds. However, mammals deeply isolated are strongly influenced isolation; Australia Madagascar, example, less diverse alone contain unique combinations traits compared other regions. Neotropical bat far more functionally Paleotropical assemblages, reflecting different trajectories that have developed over tens millions years. Our results elucidate long-lasting barriers divergent patterns, against backdrop environmental determinism predominantly structures most world.

Morphological evolution and niche conservatism across a continental radiation of Australian blindsnakes

Evolution, Год журнала: 2024, Номер 78(11), С. 1854 - 1868

Опубликована: Сен. 16, 2024

Abstract Understanding how continental radiations are assembled across space and time is a major question in macroevolutionary biology. Here, we use phylogenomic-scale phylogeny, comprehensive morphological dataset, environmental niche models to evaluate the relationship between trait environment assess role of geography conservatism radiation Australian blindsnakes. The Australo-Papuan blindsnake genus, Anilios, comprises 47 described species which 46 endemic distributed various biomes on Australia. Although expected blindsnakes be morphologically conserved, found considerable interspecific variation all traits measured. Absolute body length negatively correlated with mean annual temperature, shape ratios soil compactness. We that similar likely not result ecological convergence. Age-overlap correlation tests revealed similarity decreased relative age speciation events. also low geographical overlap suggesting largely allopatric rates secondary range overlap. Our study offers insights into eco-morphological evolution potential for phylogenetic influence scale radiations.
