एक जीवविज्ञानी जो जीवों के वर्गीकरण में उनकी संरचना और उत्पत्ति और व्यवहार के आधार पर समूहों में माहिर हैं

taxonomers शब्द के हिंदी अर्थ का उदाहरण:

इस काल में वर्गीकरण विज्ञान में बड़ी प्रगति की गई और वर्गीकरण में अनेक नई जातियाँ, वंश और कुटुंब जोड़े गए।

अठारहवीं शताब्दी में विकासवाद के विचारों का प्रभाव वर्गीकरण विज्ञान पर पड़ा।

जैव पूर्वेक्षण एवं आण्विक वर्गीकरण विज्ञान।

इसलिए इन्हें वर्गीकरण विज्ञान का जन्मदाता माना जाता है।

बीसवीं शताब्दी में किया गया वर्गीकरण विज्ञान की विशेषता है।

इस तरह से जन्तुओं एवं पादपों के वर्गीकरण को वर्गिकी या वर्गीकरण विज्ञान अंग्रेजी में वर्गिकी के लिये दो शब्द प्रयोग में लाये जाते हैं - टैक्सोनॉमी (Taxonomy) तथा सिस्टेमैटिक्स (Systematics)।

आधुनिक वर्गीकरण विज्ञान में जातियों का वर्णन पूर्णतया आकृतिक लक्षणों पर आधारित नहीं है, जैविक है, जिसकी वजह से भौगोलिक, पारिस्थितिक, जननीय तथा कुछ अन्य लक्षणों पर भी ध्यान दिया जाता है।

हक्सलि (Huxely, 1940 ई.) के विचारानुसार आधुनिक वर्गीकरण विज्ञान भूगोल, पारिस्थितिकी (ecology), कोशिकी (cytology) और आनुवंशिकी (genetics) आदि का संश्लेषण है।

पहले समय में वर्गीकरण विज्ञान का आधार था "प्रकार" (type), जिसको आकृतिक लक्षणों की सहायता से उपस्थित करते थे।

वर्गीकरण विज्ञान का इतिहास उतना ही पुराना है जितना मानव का इतिहास।

उन्होंने 1851 तथा 1854 में दो खंडों के जोड़ों में बर्नाकल के बारे में पहला सुनिश्चित वर्गीकरण विज्ञान का अध्ययन प्रस्तुत किया।

मूलतः जीवों के वर्गीकरण को "वर्गिकी" (टैक्सोनॉमी) या "वर्गीकरण विज्ञान" कहते थे।

जीवों के वर्गीकरण विज्ञान (Taxonomy) में जीवसांख्यिकी का सदा से विशेष महत्व रहा है।

taxonomers's Usage Examples:

That the palatal structure must be taken into consideration by taxonomers as affording hints of some utility there can no longer be a doubt; but perhaps the characters drawn thence owed more of their worth to the extraordinary perspicuity with which they were presented by Huxley than to their own intrinsic value, and if the same power had been employed to elucidate in the same way other parts of the skeleton - say the bones of the sternal apparatus or even of the pelvic girdle - either set might have been made to appear quite as instructive and perhaps more so.

Upon these descriptions he was still engaged till death, in 1837, put an end to his labours, when his place as Naumann's assistant for the remainder of the work was taken by Rudolph Wagner; but, from time to time, a few more, which he had already completed, made their posthumous appearance in it, and, in subsequent years, some selections from his unpublished papers were through the care of Giebel presented to the public. Throughout the whole of this series the same marvellous industry and scrupulous accuracy are manifested, and attentive study of it will show how many times Nitzsch anticipated the conclusions of modern taxonomers.

His principles, however, are those which must still guide taxonomers, notwithstanding that they have in so great a degree overthrown the entire scheme which he propounded.

Besides this, Belon disposed the birds known to him according to a definite system, which (rude as we now know it to be) formed a foundation on which several of his successors were content to build, and even to this day traces of its influence may still be discerned in the arrangement followed by writers who have faintly appreciated the principles on which modern taxonomers rest the outline of their schemes.
