Conservation genetics of the giant otter (Pteronura brasiliensis (Zimmerman, 1780)) (Carnivora, Mustelidae)

open access: yesBrazilian Journal of Biology
The giant otter (Pteronura brasiliensis) is an aquatic mammal of the Mustelidae family, endemic to South America. Its original distribution corresponds to the region from the Guyanas to Central-North Argentina, but it is extinct or on the verge of ...

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Studies on subspecies changes of rice in the Neolithic age by analysis of morphological characteristics of plant opal from Nanzhuangqiao site

open access: yes浙江大学学报. 农业与生命科学版, 2002
Analysis of plant opal has been proposed as an effective method to origin and evolution of crops. To understand subspecies and its changes of rice cultivated at the Neolithic age with changes of times, 16 soil samples, 8 earthenware fragments and burned ...

Establishment of Interspecies Somatic Cell Nuclear Transfer and Transgene‐Free Inducible Pluripotent Stem Cells for Versatile Conservation of the Germplasm Resource of Wild Boar

open access: yesAnimal Research and One Health, EarlyView.
Conserving genetic material and even increasing genetic diversity is critical. To conduct the conservation of wild boar germplasm resources, we have successfully obtained healthy cloned wild boars for the first time using interspecies somatic cell nuclear transfer and established transgene‐free iPSCs that can be used to conduct iterative rounds of gene

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

open access: yesEcography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Twenty years of dynamic occupancy models: a review of applications and look to the future

open access: yesEcography, EarlyView.
Since their introduction over 20 years ago, dynamic occupancy models (DOMs) have become a powerful and flexible framework for estimating species occupancy across space and time while accounting for imperfect detection. As their popularity has increased and extensions have further expanded their capabilities, DOMs have been applied to increasingly ...
