Biodeterioration and biodegradation of Roman monuments: A comparison of the current status of 18th century paintings by the Canalettos
(2014)
Worldwide there is an urgent need to monitor the conditions of monuments affected by biodeterioration and biodegradation, but no long term data exist for most of them. Here is an exception in the case of certain Roman ...
The geographic distribution of Costa Rican velvet worms (Onychophora: Peripatidae)
(Revista de Biologia Tropical vol.64 no.4 1401-1414 2016, 2016-06-06)
Velvet worms, “peripatus” or onychophorans, are “living fossils” that were geographically widespread in Cambrian seas but now occur exclusively on terrestrial habitats. The only extant species studied in some detail are ...
A proposed solution to the species problem in velvet worm conservation (Onychophora)
(Universidad Estatal a Distancia, 2018)
Onychophorans or velvet worm are the only phylum
without extant marine species and the only invertebrates with a true
placenta, but most species are rare and thus more likely to become
extinct. A key obstacle for ...
Oscillation of the velvet worm slime jet by passive hydrodynamic instability
(Nature Communications, 2015-03-17)
The rapid squirt of a proteinaceous slime jet endows velvet worms (Onychophora) with a unique mechanism for defence from predators and for capturing prey by entangling them in a disordered web that immobilizes their target. ...
Unexplored Character Diversity in Onychophora (Velvet Worms): A Comparative Study of Three Peripatid Species
(Sars International Centre for Marine Molecular Biology, Norway, 2012-12-17)
Low character variation among onychophoran species has been an obstacle for taxonomic and phylogenetic studies in the past, however we have identified a number of new and informative characters using morphological, molecular, ...
The relationship between humidity, light and the activity pattern of a velvet worm, Epiperipatus sp. (Onychophora: Peripatidae), from Bahía Drake, South Pacific of Costa Rica
(Instituto Internacional de Ecología (Brasil), 2018-10-31)
Even though the Onychophora represent a whole phylum, observations of their activity pattern in nature are almost
non-existent. Here we report on the relationship between humidity and light and activity pattern of a new ...
