Inverse sky islands: lowland river valleys drive microbial divergence while high elevations select for convergence in massive mountain ecosystems

Ecography, EarlyView.
Mountain ecosystems are often interpreted through the lens of the ‘sky island' model, where high‐elevation habitats function as isolated archipelagos. However, this model's applicability to massive, topographically complex mountain ranges where highlands are continuous and lowlands are fragmented remains untested.

Scrutinizing the Wallacean shortfall: global gaps in snake occurrence data across space and environment

Ecography, EarlyView.
Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...

Hybrid Osprey‐Salp Swarm Optimization Algorithm for Single and Multiobjective Optimal Power Flow in Smart Grids With Renewable Energy Integration

Energy Science &Engineering, EarlyView.
The proposed hybrid osprey‐salp swarm optimization algorithm addresses optimal power flow (OPF) problems in smart grids incorporating solar, hydro, and thermal generators. The algorithm is validated on Institute of Electrical and Electronics Engineers 30‐, 57‐, and 118‐bus test systems across five single and multiobjective OPF scenarios.

Human disturbances explain the small-island effect of large and medium-sized mammals in the largest archipelago of China

Basic and Applied Ecology
The small-island effect (SIE) is a widely accepted pattern in island biogeography where species richness varies independently of island area below an area threshold.

Insects and the city: what island biogeography tells us about insect conservation in urban areas [PDF]

Web Ecology, 2016
Habitat fragmentation caused by urbanization is considered a prominent threat to biodiversity. Urban development creates a mosaic of natural fragments which can be occupied by organisms able to survive in small spaces.

Global assessment of current extinction risks and future challenges for turtles and tortoises

Nature Communications
Turtles and tortoises (chelonians) are among the most threatened vertebrates worldwide, yet the factors determining their high extinction risk and their resilience to further challenges are not fully understood.

Trait-dependent diversification in island biogeography [PDF]

Species traits are widely hypothesized to be important drivers shaping diversification rates and biodiversity patterns, but have been neglected in the current island biogeography models. This thesis focuses on providing a new framework to investigate how

Dicrananthera hedyotidea C. Presl. (Melastomataceae) in Maranhão state, Brazil: first record and ecological niche model of the species

Nordic Journal of Botany, EarlyView.
Dicrananthera C. Presl. is a monospecific genus of the tribe Marcetieae, comprising perennial herbs typically occurring in areas adjacent to wetlands. The species exhibits a disjunct distribution, with confirmed records in both the Amazon and Atlantic Forest domains.

Connecting the distribution and diversification of marine plants

Oikos, EarlyView.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...
