Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

The Anatomical Record, EarlyView.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

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

Zoologia (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 ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The Exemplar Approach to Science and Religion [PDF]

, 2019
We can judge whether some activities are scientific or religious, depending on how similar they are to exemplar scientific activities or to exemplar religious activities, even if we cannot specify the necessary and sufficient conditions for science and ...

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby

Developmental Dynamics, EarlyView.
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Toxoplasma gondii antibodies in wild rodents and marsupials from the Atlantic Forest, state of São Paulo, Brazil

Revista Brasileira de Parasitologia Veterinária
Toxoplasma gondii is a protozoan parasite that infects a large spectrum of warm-blooded animals, including humans. Small rodents and marsupials play an important role in the epidemiology of T. gondii because they are sources of infection for domestic and

Cloacal and Ocular Microbiota of the Endangered Australian Northern Quoll

Microorganisms, 2018
The Australian northern quoll is an important predatory marsupial carnivore that is currently endangered due to inappropriate fire regimes, predation, and the spread of invasive cane toads. The microbiota of Australian marsupials has not been extensively

Global Trends in the Status of Bird and Mammal Pollinators [PDF]

, 2015
Biodiversity is declining, with direct and indirect effects on ecosystem func-tions and services that are poorly quantified. Here, we develop the first globalassessment of trends in pollinators, focusing on pollinating birds and mam-mals.
