High-resolution coproecology: Using coprolites to reconstruct the habits and habitats of New Zealand’s extinct upland Moa (Megalapteryx didinus) [PDF]

open access: yes, 2005
Knowledge about the diet and ecology of extinct herbivores has important implications for understanding the evolution of plant defence structures, establishing the influences of herbivory on past plant community structure and composition, and identifying

New finding of green algae with potential for algal biotechnology, Chlorococcum oleofaciens and its molecular investigation

open access: yesRegulatory Mechanisms in Biosystems, 2017
The practice of soil algology shows that algae from the order Chlamydomonadales are among the most poorly studied and difficult to identify due to the high heterogeneity of their morphology and ultrastructure.

Analyzing Large Data Sets: rbcL 500 Revisited [PDF]

open access: yesSystematic Biology, 1997
In 1993, Mark Chase and 41 coauthors published phylogenetic analyses of two very large data sets of nucleotide sequenc? es of the chloroplast gene rbcL, which en? codes the large subunit of ribulose 1,5-bisphosphate carboxylase. Their paper was important for several reasons. These anal?

Hybridization, polyploidy, and evolutionary transitions between monoecy and dioecy in Bryonia (Cucurbitaceae) [PDF]

open access: yes, 2008
Correns’s 1903 (Berichte der Deutschen Botanischen Gesellschaft 21: 133 – 147) crosses between a monoecious and a dioecious species of Bryonia revealed the simple Mendelian inheritance of dioecy and provided the first instance of an XY sex determination ...

Scorzonera sensu lato (Asteraceae, Cichorieae) – taxonomic reassessment in the light of new molecular phylogenetic and carpological analyses [PDF]

open access: yes, 2020
Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense.

Molecular identification and phytochemical profiling of kamiling (wild toxic plant) using thin layer chromatography

open access: yesInternational Journal of Secondary Metabolite, 2018
Some plants may only be known by the people in their own respective place. Consequently, there is a need for the authentication and further study of wild toxic plant known by indigenous people.
