Abstract: Amphibians generally have low dispersal abilities and are often habitat specialised, which makes them particularly sensitive to landscape changes, such as habitat destruction and fragmentation. Because they depend on wetlands for breeding, many conservation studies focus on aquatic habitat degradation and destruction. Additionally, few studies showed that changes in terrestrial habitats could be another threat that may cause the decline of amphibian populations. However, little is known about the terrestrial habitat preferences of most species. Although the proximity of forests and wetlands was expected to be positively related to amphibian presence, while human-modified habitats were expected to be avoided by these species, we still have little information on how these responses are species-specific. Based on an ecological niche factor analysis completed by partial least squares path modelling, we tested whether or not relationships between terrestrial and aquatic habitat parameters and occurrences are congruent across a metacommunity of seven amphibian species co-occurring at the regional spatial scale. We highlight that habitat type could strongly affect amphibian presence at large spatial scales, but in different ways. Agricultural landscapes, semi-natural areas and fragmented-landscape parameters showed expected negative correlations with the presence of some species. However, these habitats were also positively associated to the presence of other species. Indeed, because they could offer some benefits, some species could show a preference for these landscapes. Our results should have implications in conservation programmes, and could help predict future distribution and responses of these species to global change, which could be different among species.

IMPORTANT NOTE - JUNE 2020

Please note that as from Volume 31 Number 1 (January 2021) on, the Herpetological Journal will be available as an online publication only - the last print edition will be Volume 30 Number 4.   

Aligning with this change, it is now no longer possible to purchase a subscription that includes a print copy of the HJ.  All members who have existing HJ print subscriptions that remain active as at end June 2020 will receive the full four 2020 print editions.  New subscribers or renewals after this time will only have option to subscribe to the online only subscription package.  Subscription pricing has been amended to reflect the content changes.
