Land-use change interacts with island biogeography to alter bird community assembly

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2018)

Published: March 13, 2024

Anthropogenic activities have reshaped biodiversity on islands worldwide. However, it remains unclear how island attributes and land-use change interactively shape multiple facets of through community assembly processes. To answer this, we conducted bird surveys in various types (mainly forest farmland) using transects 34 oceanic land-bridge the largest archipelago China. We found that species richness increased with area decreased isolation, regardless intensity change. forest-dominated habitats exhibited lower than farmland-dominated habitats. Island assemblages generally comprised share more similar traits or evolutionary histories (i.e. functional and/or phylogenetic clustering) expected if were randomly assembled. Contrary to our expectations, observed clustered large close islands, whereas small islands. These contrasting results indicate interacts biogeography alter birds inhabited Our findings emphasize importance incorporating human-modified when examining biota, further suggest agricultural landscapes may play essential roles protecting countryside biodiversity.

Intensive human land uses negatively affect vertebrate functional diversity

Ecology Letters, Journal Year: 2021, Volume and Issue: 25(2), P. 330 - 343

Published: Nov. 23, 2021

Land-use change is the leading driver of global biodiversity loss thus characterising its impacts on functional structure ecological communities an urgent challenge. Using a database describing vertebrate assemblages in different land uses, we assess how type and intensity use affect diversity vertebrates globally. We find that human uses alter local by driving declines diversity, with strongest effects most disturbed (intensely used urban sites, cropland pastures), among amphibians birds. Both tropical temperate areas experience important losses, which are only partially offset gains. Tropical more likely to show decreases exceed those expected from species alone. Our results indicate land-use non-randomly reshapes assemblages, raising concerns about continuation processes sustained vertebrates.

Contemporizing island biogeography theory with anthropogenic drivers of species richness

Authorea (Authorea), Journal Year: 2022, Volume and Issue: unknown

Aim : Island biogeography theory states that species richness increases with habitat diversity and decreases isolation from source pools. However, ecological must incorporate effects of human activity to explain contemporary patterns biodiversity. We contemporized island by conceptualizing trajectories how changes over time accelerating land development economic trade, which increase extinction immigration rates, respectively. With this theory, we then articulate empirically assess expected relationships native, introduced, total natural anthropogenic metrics Location Greater Caribbean region. Time Period Database finalized in 2020. Methods built a database 1042 native introduced reptiles amphibians (herps) for 840 islands. For each island, calculated pools used linear model averaging the under 15 major herp clades . Results Natural exhibited positive richness, strengthening richness–area across clades. Geographic negative weakening richness–isolation relationships. Economic area, based on developed land, isolation, maritime but relationships, respectively, richness. Total these two were strongest many species. Main Conclusion A biogeographic includes trade explained current patterns. As continues accelerate, here will increasingly predict Anthropocene.

Island area and remoteness shape plant and soil bacterial diversity through land use and biological invasion

Functional Ecology, Journal Year: 2023, Volume and Issue: 37(5), P. 1232 - 1244

Published: March 7, 2023

Abstract Biodiversity is declining dramatically due to human‐driven land use change and biological invasion, but our knowledge of how such drivers influence plant heterotroph diversity on island ecosystems remains limited. Historically biogeography theory has focused solely direct effects size remoteness biodiversity, these factors can also indirectly affect species gain and/or loss through impacting invasion. We built the structural equation model explore remoteness, indirect via intensity pinewood nematode plants soil bacteria across 37 continental shelf islands in largest land‐bridge archipelago eastern China. As expected we found that increasing area directly promoted diversity. However, increased with which diversity, pine forest by invasion reduced Island only loss. Soil bacterial was negatively impacted electrical conductivity likely caused greater salinity from sea spray. Furthermore, decreased conductivity, Our findings highlight relevance understanding human impacts Anthropocene, there a need more explicitly recognizing biodiversity not directly, their human‐induced as Read free Plain Language Summary for this article Journal blog.

Published: Jan. 13, 2025

Understanding the distribution patterns and driving mechanisms of bamboo species diversity on islands is essential for advancing knowledge island ecosystem processes informing strategies resource conservation management. This study utilized standardized major axis regression (SMA) to assess effects area isolation across 30 in Fujian, China. Furthermore, a partial least squares structural equation model (PLS-SEM) was constructed explore underlying richness. analysis incorporated six key environmental factors—island size, isolation, shape, climate, development intensity, habitat heterogeneity—spanning total 12 variables. The primary findings were as follows: (1) Eight genera twenty-nine identified Fujian islands. Species richness increased significantly with area, consistent theory effects, while had no significant impact (2) Different reproductive types exhibited distinct responses conditions. evident species–area relationship slopes (z-values): SR = 2.07; monopodial 0.94; sympodial 0.82; polycyclic 0.44. These variations highlight ecological adaptability functional traits different within ecosystems. (3) Among factors, exerted greatest influence richness, underscoring its role driver strategies. (4) Island also impacted indirectly through their intensity. In conclusion, are primarily shaped by followed intensity heterogeneity. contrast, play relatively minor roles. provides critical insights into interplay heterogeneity shaping diversity. offer valuable foundation conservation, management, sustainable development.

Urbanization is expanding worldwide with major consequences for organisms. Anthropogenic factors can reduce the fitness of animals but may have benefits, such as consistent human food availability. Understanding anthropogenic trade-offs critical in environments variable levels natural availability, Galápagos Islands, an area rapid urbanization.
