Übersetzung für "Reproduktionsrate" in Englisch

The abundance of m?mane seeds affects reproduction rates and adult survival.

At the EU-25-level fertility has remained 30% below the replacement ratio since 1995.

Its slow reproductive rate would limit its capacity to recover from population depletion.

When that happens, the process of growing the crystals slows down, and this slows down the rate of how much their exoskeleton is growing.

In 1999, the Jewish total fertility rate was 3.8 children per woman, while the Palestinian rate was 4.4.

The high rate of reproduction of lice only adds variety and an abundance of interesting details in this process.

The high rate of reproduction of lice only adds variety and abundance of interesting details in this process.

This either occurs through natural selection (different reproduction rate) or randomly through so-called genetic drift.

Due to his high reproduction rate caused by the fast growth bamboo is an important raw material.

The health of the predators, particularly their reproductive rate, mirrors the real degree of marine pollution.

The vegetative reproduction rate was accelerated in the first 20 days after the end of exposure.

It also emerged clearly from the debate that that this was a general European question, since despite the fact that Ireland, for example, has at present the highest number of live childbirths per woman of childbearing age, it has also recorded a decline over the past 20 years sharper than just about any other country, and the current level is not sufficient to maintain demographic stability.

And it declined very fast -- a classic boom and bust fishery, which suggests that a stock has been depleted or there's low reproductive rates.

The International Union for Conservation of Nature (IUCN) has assessed this species as Vulnerable, as it is subjected to intense fishing pressure and its low reproductive rate renders it susceptible to population depletion.

One of the main problems is the depleted state of European fish stocks: 88% of stocks are overfished (against a global average of 25%) and 30% are "outside safe biological limits", i.e. they cannot reproduce at normal rate because the parenting population is too depleted.

Mr Buffetaut stressed that inability to reach replacement-level fertility was an issue in a large number of EU Member States, thus necessitating the introduction of more effective policies in support of families.

Secondly there has been a significant fall in the fertility rate, which in some Member States is now below the replacement rate.

Its gregarious instinct at the time of spawning - which explains the fabulous catches made by certain trawlers - and a very low reproduction rate make orange roughy vulnerable to intensive fishing effort.

In each of the new Member States, reproduction rates are predicted to rise to 2% and above in this decade and the following.

On the other hand, Ireland (1.98) and France (1.90) have the highest total fertility rates, but still short of the replacement level.

The completed fertility changes far less abruptly over time and isnow around 1.7, still well below the reproduction level (2.1 children per woman).

The efficiency of sheep breeding could be distinctly increased if attempts would be successful to bring ewes artificially to estrus and to conception during this anestrous period, as a consequence whereof the annual reproduction rate would be practically doubled.
