Which of the following groups of species are typical of grassland habitats in India

• Black buck, wolf, great Indian bustard, lesser florican   

• Spotted deer, dhole, peacock, finch lark  

• Sambar, tiger, paradise fly catcher   

• Otter, cormorant, darter, pelican     

Batrachochytrium dendrobatidis, a fungus, has been implicated in the decline of populations of

• Fish

• Frogs

• Pelicans

• Bats

During a field study, three insects with the following characteristics were observed:

A. Elongate, membranous wings with netlike venation, long and slender abdomen, large compound eyes.

B. Small bodied, sucking mouth parts, narrow wings fringed with setae.

C. sclerotized forewings, membranous hindwings, chewing mouth parts

They can be identified to their respective orders as

• A – Orthoptera; B – Hemiptera; C – Coleoptera  

• A – Odonata; B – Coleoptera; C – Hemiptera  

• A – Orthoptera; B – Odonata; C – Coleoptera

• A – Odonata; B – Thysanoptera; C – Coleoptera

Which of the following is NOT true for a critically endangered species?

• Reduction of population breeding ability due to increased relatedness through the action of incompatibility mechanisms in plants or behavioral difficulties in animals.

• The individuals of the species which have declined to low numbers are still a genetically open system.   

• Loss of some alleles from the species causing loss of genetic diversity with consequent inability to respond rapidly to selection.

• Expression of deleterious alleles and increased homozygosity increases mortality of young, and inbreeding depression leads to reduced offspring fitness.

Suppose you discovered a new species about which you know only two facts: it is small sized ( <10 cm) and short lived (<20 days). Which of the following reproductive strategies is most likely to be true for this species?

• Breeds early and more than once in life and produces large number of small-sized offspring. 

• Breeds late and only once in life and produces large number of small sized offspring.

• Breeds early and only once in life and produces large number of small sized offspring.

• Breeds early and only once in life and produces a small number of large sized offspring.

• Facultative anaerobe

A plant species has been described for the first time by author ‘x’. Later, the species has been transferred to some other genus by author ‘y’. Then the author citation for the new combination will be
