Endangerment and protection of amphibians in the republic of Croatia [PDF]

open access: yes, 2018
Vodozemci su razred unutar potkoljena kralješnjaka. Oni su prva skupina koja postupno prelazi s vodenog načina života na kopneni. Zbog svojih fizioloških i morfoloških osobina jedna su od najrasprostranjenijih, ali i najugroženijih skupina kralješnjaka ...

A signature of dynamic biogeography: enclaves indicate past species replacement [PDF]

open access: yes, 2017
Understanding how species have replaced each other in the past is important to predicting future species turnover. While past species replacement is difficult to detect after the fact, the process may be inferred from present-day distribution patterns ...

Exceptional soft tissues preservation in a mummified frog-eating Eocene salamander [PDF]

open access: yes, 2017
Fossils are almost always represented by hard tissues but we present here the exceptional case of a three-dimensionally preserved specimen that was ‘mummified’ (likely between 40 and 34 million years ago) in a terrestrial karstic environment.

Ferromagnetic material in the eastern red-spotted newt notophthalmus viridescens [PDF]

open access: yes, 1999
Behavioral results obtained from the eastern red-spotted newt (Notophthalmus viridescens) led to the suggestion of a hybrid homing system involving inputs from both a light-dependent and a non-light-dependent mechanism. To evaluate the possible role of a

Present and past climatic effects on the current distribution and genetic diversity of the Iberian spadefoot toad (Pelobates cultripes): an integrative approach [PDF]

open access: yes, 2017
Aim: Predicting species responses to global change is one of the most pressing issues in Conservation Biogeography. A key part of the problem is understanding how organisms have reacted to climatic changes in the past.

Efficient screening for ‘genetic pollution’ in an anthropogenic crested newt hybrid zone [PDF]

open access: yes, 2016
Genetic admixture between endangered native and non-native invasive species poses a complex conservation problem. Decision makers often need to quickly screen large numbers of individuals and distinguish natives from morphologically similar invading ...
