Animal Conservation, EarlyView.Guam's lizard fauna has been devastated by the invasive brown treesnake, but recent advances in brown treesnake control have opened the possibility of reintroducing native lizards. We simulated different strategies for reintroducing lizards to Guam, comparing the timing and age‐structure of releases.

Studies on Maltese Consanguinity [PDF]
, 2003 The possible genetic consequences of consanguinity have been known from ancient times, though different societies have held varying views. Some have encouraged consanguinity as desirable and the classic examples are the sister brother marriages of the ...

Animal Conservation, EarlyView.The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...

EFFECT OF INBREEDING ON MORTALITY OF CAPTIVE TIGER [PDF]
Exploratory Animal and Medical Research, 2017 A study was carried out on the captive tigers of Nandankanan zoo, Odisha, India, to conclude any deleterious effect of inbreeding on mortality. A pedigree path analysis of 342 tigers was done to estimate the inbreeding coefficient of each tiger from ...

Animal Conservation, EarlyView.Long‐term monitoring has revealed hybridisation attempts between the Critically Endangered Kuaka Whenua Hou (KWH, Pelecanoides whenuahouensis) and the abundant Kuaka (P. urinatrix). Here we use modelling based on population monitoring data in tandem with genomic data to investigate these attempts and the risk they pose to KWH recovery.

A century of theories of balancing selection
Biological Reviews, EarlyView.ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
