Abstract:

The Balkan Peninsula is recognized as an important centre of native and endemic plant species diversity as well as an important wildlife refuge area. However, although Croatia hosts more than half of plant species found on the Balkan Peninsula, the endemic taxa have never been evaluated or used to define conservation priorities. We analyzed the qualitative composition of the endemic and range restricted species, their spatial distribution, centres of endemism, and conservation status (non-IUCN). We generated an updated and annotated checklist of 349 endemic or range-restricted plant taxa (6.9%

Abstract:

Knowledge on how life history traits affect distribution in range-restricted and endemic plants is paramount for conservation and management, particularly for threatened species. Traits relating to dispersal ability are important in the ongoing persistence of range restricted species and may present a pathway to extinction or invasion. This is evident in the highly diverse and cosmopolitan genus Senecio (Asteraceae), where both threatened and invasive species occur within Australia. In this study, propagule geometry, settling velocity and dispersal potential for two range-restricted and threat

Abstract:

Cliffs are among the environments with the most adverse conditions for living organisms because of the limited availability of soil, moisture, and nutrients, and owing to the harsh conditions of exposure. They constitute shelters for rare, endemic, and range-restricted plant taxa.

Abstract:

Understanding how species attain their geographical distributions and identifying traits correlated with range size are important objectives in biogeography, evolutionary biology and biodiversity conservation. Despite much effort, results have been varied and general trends have been slow to emerge. Studying species pools that occupy specific habitats, rather than clades or large groupings of species occupying diverse habitats, may better identify ranges size correlates and be more informative for conservation programmes in a rapidly changing world.

Larks constitute an avian family of exceptional cryptic diversity and striking examples of convergent evolution. Therefore, traditional morphology-based taxonomy has recurrently failed to reflect evolutionary relationships.

Here, we combine morphometrics and mitochondrial DNA to evaluate the taxonomy of Calandrella larks, with particular focus on the African C. cinerea and the Asian C.

The new species can be assessed as critically endangered due to its very narrow and obviously shrinking range and habitat, an easy accessibility of known localitie

Abstract:

Liromissus, a new genus of chionine bivalve from the Neogene of Venezuela, serves as an example of the link between geographic range, endemism and extinction susceptibility. Unlike other Neogene tropical American chionine genera, Liromissus was not widespread in the tropical Western Atlantic and Eastern Pacific, but was instead restricted to the Atlantic Gatunian region. Late Neogene extinctions in tropical America affected taxa with restricted geographic ranges, and regions with higher degrees of endemism more severely. Accordingly, Liromissus is the only tropical chionine genus to suffer ext

Abstract:

Amphibians are more threatened than any other vertebrate class, yet evidence for many threats is missing. The Cape lowland fynbos (endemic scrub biome) is threatened by habitat loss, and natural temporary freshwater habitats are removed in favour of permanent impoundments. In this study, we determine amphibian assemblages across different freshwater habitat types with special attention to the presence of invasive fish. We find that anuran communities differ primarily by habitat type, with permanent water habitats having more widespread taxa, while temporary water bodies have more range restric

The name Terminalia circumalata F.Muell. is resurrected as a taxon endemic to the Pilbara region, with T. canescens not occurring in that region.

Sisyranthus species are cryptic in both their habit and small size of their flowers making them difficult to find in the wild. The genus was last revised in Flora Capensis (1908) and since then, two new species have been described. Currently it comprises 13 recognised species endemic to southern Africa. Many of these are range-restricted and poorly known. In this contribution the genus is further expanded by describing two novel species. Full descriptions, assessment of conservation status, distribution maps and line drawings of the new taxa are presented.

The distribution of taxa was related (ρ=0.592, P<0.001) to variations in water depth, latitude, substrate type and phytodetritus. High phytodetritus cover was associated with muddy/sandy sediments and abundant holothurians and amphipods, while

Understanding biogeographical patterns is a challenging task, particularly in the case of poorly studied organisms, whose phylogenetic affinities and ecological needs are not yet understood. Such a case is common among invertebrates and particularly among insects, whose extensive diversity may hamper full and deep comprehension of their ecological and evolutionary patterns. Within insects, orthopterans also represent a relatively poorly studied group. Building knowledge upon biogeography and evolution of orthopterans may provide key insights to their conservation, especially in the case of ran
