Including autapomorphies is important for paleontological tip-dating with clocklike data, but not with non-clock data [PDF]
Tip-dating, where fossils are included as dated terminal taxa in Bayesian dating inference, is an increasingly popular method. Data for these studies often come from morphological character matrices originally developed for non-dated, and usually ...

The fern genus Lepisorus represents one of the most complicated and controversial lineages in Polypodiaceae, with about 80 species which have been classified into several separate genera, and is notorious for its taxonomic difficulty. Despite progress in

Recessions and total factor productivity: Evidence from sectoral data
The recent COVID-19 crisis has generated a concern that productivity (which was already at historically low levels) may further decline. From a theoretical standpoint, the recessions-total factor productivity (TFP) nexus is ambiguous à priori. This paper empirically examines the dynamic impact of recessions on TFP.

The philosophy of total evidence and its relevance for phylogenetic inference
The test of congruence under total evidence as used in systematics has been tied to a Popperian philosophy of science, but is here shown to be related to the coherence theory of truth in metaphysics and thus to coherentism in epistemology. Since the test

The willistoni species subgroup has been the subject of several studies since the latter half of the past century and is considered a Neotropical model for evolutionary studies, given the many levels of reproductive isolation and different evolutionary ...

Hypothetico-deductivism in systematics: fact or fiction?
Phylogenetic systematics (the cladistic analysis of phylogenetic relationships) is not hypotheticodeductively structured (in the sense of a covering law model of scientific explanation).

Unpacking Total Factor Productivity on Dairy Farms Using Empirical Evidence
This study examines the farm-level factors that influence differences in total factor productivity (TFP) on dairy farms. To this end, a fixed-effects regression approach is applied to panel data for dairy farms obtained from the Farm Accountancy Data ...
