A number of conservation measures that aim to alleviate negative genetic and demographic impacts of reduced connectivity can be employed for the long-term conservation of recently fragmented species and those for which further or future population fragmentation is envisaged.
The main threats to the species' survival are population fragmentation and isolation of the existing herds.
Our results highlight the competing nature of techniques to minimize population fragmentation and mortality.
We suggest that the construction of passages for amphibians across rural roads would potentially mitigate population fragmentation of endangered species like the anuran A. obstetricans.
Changing climate, population fragmentation and a lack of phenology data means reliable methods are required to collect seeds from as many species as possible to conduct trials for germination, cryopreservation and reintroduction programmes.
The low dispersal capacity of sand flies could lead to population isolation due to geographic barriers, climate variation, or to population fragmentation associated with specific local habitats due to landscape modification.
We chose Q. macrocarpa because its scattered, pre-settlement distribution in the prairie/savanna landscape of this region allows us to examine the effects of long-term population fragmentation on a wind-pollinated tree species.
The causes are thought to comprise the extensive spread of chemical pollutants affecting both bat and prey populations, changes in landscape composition and structure leading to population fragmentation or roost deterioration, and infectious diseases.
The Red-billed Chough (Pyrrhocorax pyrrhocorax) is a vulnerable corvid that exhibits high levels of population fragmentation and decline trends, due to its dependence on open habitats shaped by traditional agriculture and pastoralism.
Threats to B. cuneata include land clearing, which leads to direct plant loss and population fragmentation, grazing pressure, competition from exotic weeds, changes to the fire regime, and encroaching salinity.
In spite of the negative effects of population fragmentation, isolated populations do persist under some circumstances.
