Climatic drivers prevail in montane and lowland Odonata latitudinal diversity gradients, but human modification erodes lowland patterns

open access: yesEcography, EarlyView.
Latitudinal diversity gradients (LDGs) arise from the interplay of historical, ecological, and evolutionary processes, yet these drivers may differ across landforms. Mountains, with steep elevational and climatic gradients, often sustain distinct diversity dynamics compared with adjacent lowlands, where vertical climatic gradients are weak and human ...

Island biogeography of plants and humans

open access: yes, 2022
Islands have always attracted considerable research effort due to their unique geography and biota. However, the biogeography of islands still presents substantial challenges. For instance, islands often sustain high rates of plant invasions.

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

open access: yesEcography, 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.

Differential influences of island biogeographic effects on the diversity among three plant life-forms

open access: yesGlobal Ecology and Conservation
Traditional island biogeography posits that area and remoteness are key determinants of species richness. However, this theory is challenged by recent changes in species dispersal patterns caused by human activity and climate change.

The concerted emergence of well-known spatial and temporal ecological patterns in an evolutionary food web model in space

open access: yesScientific Reports, 2021
Ecological systems show a variety of characteristic patterns of biodiversity in space and time. It is a challenge for theory to find models that can reproduce and explain the observed patterns. Since the advent of island biogeography these models revolve

Speciation and endemism under the model of island biogeography

open access: yes, 2009
: Speciation has been considered as a primary process contributing to species diversity, but its contribution to the diversity of local communities has not been fully appreciated. Based on the theory of classic island biogeography, we derived a model for

Island biogeography, the effects of taxonomic effort and the importance of island niche diversity to single-island endemic species [PDF]

open access: yes, 2013
Island biogeography theory is fundamentally reliant on measuring the number of species per island and hence has taxonomy at its foundation. Yet as a metric used in tests of the theory, island species richness (S) has varied with time according to the ...

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

open access: yesEcography, 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 ...

Analysis of amphibian diversity and its influencing factors in the coastal islands of southern Zhejiang [PDF]

open access: yesNature Conservation
The theory of island biogeography posits that geographical features play a key regulatory role in shaping biodiversity. As a dispersal-limited group, amphibians are particularly sensitive to island effects.

Association of insularity and body condition to cloacal bacteria prevalence in a small shorebird.

open access: yesPLoS ONE, 2020
Do islands harbour less diverse disease communities than mainland? The island biogeography theory predicts more diverse communities on mainland than on islands due to more niches, more diverse habitats and availability of greater range of hosts.
