Biochemical pedomorphosis and genetic assimilation in the hypoxia adaptation of Tibetan antelope

Developmental shifts in stage-specific gene expression can provide a ready mechanism of phenotypic change by altering the rate or timing of ontogenetic events. We found that the high-altitude Tibetan antelope (Panthelops hodgsonii) has evolved an adaptive increase in blood-O2 affinity by truncating the ancestral ontogeny of globin gene expression such …

Variation in forewing size linked to migratory status in Monarch butterflies

Long-distance migration can be seen throughout the animal kingdom and can have large impacts on population dynamics and species distributions. The act of migration itself also affects the evolution of a species, as evolutionary forces select for certain characteristics in animals conducting long-distance migration. Monarch butterflies are best known for …

Zebra stripes through the eyes of their predators, zebras, and humans

The century-old idea that stripes make zebras cryptic to large carnivores has never been examined systematically. We evaluated this hypothesis by passing digital images of zebras through species-specific spatial and colour filters to simulate their appearance for the visual systems of zebras’ primary predators and zebras themselves. We also measured …

Do healthy Monarchs migrate farther? Tracking natal origins of parasitized vs. uninfected Monarch butterflies overwintering in Mexico

Long-distance migration can lower parasite prevalence if strenuous journeys remove infected animals from wild populations. We examined wild monarch butterflies (Danaus plexippus) to investigate the potential costs of the protozoan Ophryocystis elektroscirrha on migratory success. We collected monarchs from two wintering sites in central Mexico to compare infection status with …

New bird found in India - Discovery in Nicobar second since Independence

Calcutta, Aug. 1: Scientists from the Zoological Survey of India (ZSI) have discovered a new bird on the Great Nicobar Island, the second report of a bird species previously unknown to science in independent India. ZSI scientists S. Rajesh Kumar and C. Raghunathan spotted the species, named the Great Nicobar …

Study maps hotspots of human-animal infections

Mad-cow, bird-flu or swine-flu - the world is more than familiar with “human-animal diseases”. A global study mapping these diseases, that jump species from animal hosts to humans, found that an “unlucky” 13 zoonoses were responsible for 2.4 billion cases of human illness and 2.2 million deaths per year. And …

Govt bans use of live animals for edu, research

Mumbai: The Union ministry of environment and forests (MoEF) has banned the use of live animals in dissection and other experiments in educational and research institutions. But scientists conducting new molecular research will be exempted from the ban. Based on the Prevention of Cruelty to Animals Act (1960), the MoEF …

Conservation and collection of insects in India are mutually beneficial, NOT harmful a simple reality explained

We still do not know 60-70% of the living insect species in India and almost all of these yet unnamed species probably occur only in our Protected Areas now. 'No permits to survey in' or 'unrestricted access to these areas given to qualified specialist scientists' means no knowledge about three …

Ban dissection in colleges, urges PETA

Animal rights group People for Ethical Treatment of Animals (PETA) on Tuesday demanded a ban on dissection in zoology classes in universities and colleges. It said a central panel comprising experts from University Grant Commission and HRD Ministry have recommended that colleges should reduce animal dissection in zoology and life …

Here the researchers present an observation on the rutting behaviour of the nationally threatened population of Red Deer in Kashmir, Cervus elaphus hanglu, commonly known as Hangul, in the Dachigam National Park (DNP). Original Source

Animal evolution during domestication: the domesticated fox as a model

We review the evolution of domestic animals, emphasizing the effect of the earliest steps of domestication on its course. Using the first domesticated species, the dog (Canis familiaris) as an illustration, we describe the evolutionary specificities of the historical domestication, such as the high level and wide range of diversity. …

Ethnozoology of Galo tribe with special reference to edible insects in Arunachal Pradesh

The paper explored the diversity of edible insects, collection patterns and temporal availability in the West Siang district of Arunachal Pradesh, Northeast India. The district is inhabited by the Galo, Adi, Memba and Khamba tribes. However, the study only explored the ethnozoology of Galo tribe. The study reveals that the …

Right beat

Researchers from Johns Hopkins Medical Institutions have successfully implanted genetically engineered human embryonic stem (ES) cells into the hearts of guinea pigs (Circulation, Vol 432, No 7015). If replicated in humans, the technique could replace electronic pacemakers used by hundreds of thousands of people worldwide. These devices are used to …

A gory lab

western biomedical scientists working on primates are flocking to China, which lacks stern regulations on animal research. Absence of animal rights groups and low cost of research in the communist nation also encourage them, making many of them even take up full-time positions in various Chinese institutions engaged in primate …

Contending with Darwin

No one who reads a newspaper, however cursorily, could miss the news that Stephen Jay Gould, Professor of Zoology at Harvard University, died of lung cancer on May 20, 2002. He had fought his way out of another cancer, a rare form of abdominal cancer, 20 years ago. His reaction …
