Partial dosage compensation in Strepsiptera, a sister group of beetles. [PDF]

open access: yes, 2015
Sex chromosomes have evolved independently in many different taxa, and so have mechanisms to compensate for expression differences on sex chromosomes in males and females. Different clades have evolved vastly different ways to achieve dosage compensation,

Genetic characterization of flea-derived Bartonella species from native animals in Australia suggests host-parasite co-evolution [PDF]

open access: yes, 2011
Fleas are important arthropod vectors for a variety of diseases in veterinary and human medicine, and bacteria belonging to the genus Bartonella are among the organisms most commonly transmitted by these ectoparasites.

Anatomical study of brachial plexuses of a koala, a Tasmanian devil, and a common ringtail possum

open access: yesFolia Morphologica
BACKGROUND: Marsupials have a narrower range of forelimb morphological features than placental mammals. It is hypothesised that this is due to a constraint in the reproductive biology of marsupials.

Plantation forests and biodiversity conservation [PDF]

open access: yes, 2003
There are five key reasons why biodiversity conservation should be considered a part of plantation management. (1) The plantation estate is large, and balancing various land management values with wood and pulp production is important when extensive ...

Marked decline in forest-dependent small mammals following habitat loss and fragmentation in an Amazonian deforestation frontier [PDF]

open access: yes, 2020
Agricultural frontier expansion into the Amazon over the last four decades has created million hectares of fragmented forests. While many species undergo local extinctions within remaining forest patches, this may be compensated by native species from ...

Community structure and population dynamics of small mammals in an urban-sylvatic interface area in Rio de Janeiro, Brazil

open access: yesZoologia (Curitiba), 2018
The Atlantic Forest is one of the most disturbed Brazilian biomes, with 183 out of 298 species of mammals occurring in the state of Rio de Janeiro. In this study, we aimed to characterize the diversity, community structure, and habitat use of small ...

American marsupials chromosomes: why study them?

open access: yesGenetics and Molecular Biology
Marsupials, one of the three main groups of mammals, are only found in Australia and in the American continent. Studies performed in Australian marsupials have demonstrated the great potential provided by the group for the understanding of basic genetic ...

Marsupials and monotremes sort genome treasures from junk [PDF]

open access: yes, 2016
A recent landmark paper demonstrates the unique contribution of marsupials and monotremes to comparative genome analysis, filling an evolutionary gap between the eutherian mammals (including humans) and more distant vertebrate ...

Global priorities for conservation across multiple dimensions of mammalian diversity [PDF]

open access: yes, 2017
Conservation priorities that are based on species distribution, endemism, and vulnerability may underrepresent biologically unique species as well as their functional roles and evolutionary histories.

Marsupial-specific microRNAs evolved from marsupial-specific transposable elements [PDF]

open access: yesGene, 2009
Using a direct miRNA cloning strategy we previously identified fourteen marsupial- or species-specific microRNAs in the marsupial species Monodelphis domestica. In the present study we examined each of the pre-miRNAs and their flanking sequences and demonstrate that half of these miRNAs evolved from marsupial-specific transposable elements.
