IMPACT OF HIGH TROPONIN LEVEL ON THE OUTCOME IN COVID-19 POSITIVE PATIENTS


Benefits of extra begging fail to compensate for immunological costs in southern shrike (Lanius meridionalis) nestlings.

Theoretical models aimed at explaining the evolution of honest, informative begging signals employed by nestling birds to solicit food from their parents, require that dishonest signalers incur a net viability cost in order to prevent runaway escalation of signal intensity over evolutionary time.Previous attempts to determine such a cost empiricall

The coexistence of hermaphroditic and dioecious plants is associated with polyploidy and gender dimorphism in Dasiphora fruticosa

Dasiphora fruticosa comprises male, female and hermaphrodite plants, which are distributed sympatrically in some populations on the Qinghai-Tibet Plateau.To explore what governs the coexistence of these three sexual phenotypes, we investigated the DNA contents, Dong Quai pollen and ovule production, pollen deposition, and performed hand-pollination

Estimating uncertainty of North American landbird population sizes

An important metric for many aspects of species conservation planning and Spray Arm Retaining Cap risk assessment is an estimate of total population size.For landbirds breeding in North America, Partners in Flight (PIF) generates global, continental, and regional population size estimates.These estimates are an important component of the PIF specie
