Ecogeographic size variation in small-bodied subfossil primates from Ankilitelo, southwestern Madagascar

Abstract

Variation in body size is well documented for both extant and extinct Malagasy primates, and appears to be correlated with geographic patterns of resource seasonality. Less attention has been paid to extant lemurs in subfossil collections, although it has been suggested that subfossil forms of extant species are characterized by greater size than their modern counterpart. This trend of phyletic size change has been related to climate change, habitat fragmentation, or human hunting. However, space- and time-averaging in the subfossil samples of previous studies may have obscured more general ecogeographic patterns underlying these size differences. Our objective is to examine size variation in subfossil still-extant primates within a regional comparative context to determine if subfossil and living forms conform to similar ecogeographic patterns. We report on the subfossil still-extant primate assemblage from Ankilitelo, southwestern Madagascar (approximately 500 yr BP) to test this hypothesis. The Ankilitelo primates were compared with museum specimens of known locality. Extant taxa were assigned to one of five distinct ecogeographic regions, including spiny thicket, dry deciduous forest, succulent woodland, lowland and subhumi...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
