New and updated stellar parameters for 71 evolved planet hosts. On the metallicity - giant planet connection [PDF]

, 2013
It is still being debated whether the well-known metallicity - giant planet correlation for dwarf stars is also valid for giant stars. For this reason, having precise metallicities is very important. Different methods can provide different results that lead to discrepancies in the analysis of planet hosts.

Developmental life stages of the Pickersgill's reed frog (Hyperolius pickersgilli) in an ex‐situ environment at Johannesburg Zoo's captive breeding facility, South Africa

Zoo Biology, Volume 41, Issue 6, Page 533-543, November/December 2022., 2022
Stages of tadpole development from Week 1 to Week 8 in Pickersgill's reed frogs bred in captivity at Johannesburg Zoo, South Africa. Abstract Globally, the threats of habitat loss and disease on amphibian survival have necessitated the creation of ex‐situ insurance populations as a conservation tool. We initiated a captive breeding project to create an

Ambiguity in guideline definitions introduces assessor bias and influences consistency in IUCN Red List status assessments [PDF]

, 2015
The IUCN Red List is the most widely used tool to measure extinction risk and report biodiversity trends. Accurate and standardized conservation status assessments for the IUCN Red List are limited by a lack of adequate information; and need consistent ...

Boswellia oropedionis (Burseraceae) sp. nov., a frankincense tree from Socotra, and notes on B. ameero and B. bullata

Nordic Journal of Botany, EarlyView.
The new species Boswellia oropedionis Thulin and M.H.Weber is described, illustrated by photographs and mapped. This tree is only known from a small population growing on level limestone on the Qatariyah plateau in southern Socotra and is the twelfth endemic species of Boswellia from the Socotra archipelago. It differs from B.

Maximum longevity and juvenile mortality in zoo‐housed mangabeys

Zoo Biology, Volume 41, Issue 6, Page 522-532, November/December 2022., 2022
The international studbooks of two Lophocebus mangabey species were analyzed. Sex, as well as traits of the mother, serve as proxies for the maximum longevity of individuals. Also, intercontinental differences in cumulative survival rates seem to exist for the captive populations of these mangabeys; underlying effects remain to be discovered.

Relatedness, trait evolution, and climatic niche divergence in mammalian island endemics

Oikos, EarlyView.
Island mammals have influenced ecological and evolutionary theory since Darwin, and many of them provide textbook examples of the dramatic morphological evolution that often occurs in island communities. However, patterns of evolution in the climatic niches of island mammals have yet to be fully explored.
