A histology-free description of Lineus marcosii (Pilidiophora: Lineidae), a cryptic species resembling Lineus lacteus

Cryptic biodiversity is one of the main challenges to overcome for an accurate characterization of Earth’s biodiversity. The nemertean species Lineus lacteus has been recorded from Sweden to the Black Sea since its description in the first half of the ...

Cuticular hydrocarbons as potential mediators of cryptic species divergence in a mutualistic ant association

Ecology and Evolution, 2019
Upon advances in sequencing techniques, more and more morphologically identical organisms are identified as cryptic species. Often, mutualistic interactions are proposed as drivers of diversification. Species of the neotropical parabiotic ant association

Bringing the Lab to the Field: Exploring Water‐Borne Corticosterone as a Physiological Indicator in Captive and Wild Common Frog Larvae (Rana temporaria)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Assessing physiological condition in wild populations is important for understanding how environmental variation shapes organismal performance. Water‐borne corticosterone (WB‐CORT) sampling shows promise for studying amphibian stress physiology, but its ecological relevance and limitations require evaluation, particularly when methods ...

Translating Riedl: The Circulation and Operationalisation of Evolutionary Ideas

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Rupert Riedl's Order in Living Organisms proposed a systems theory of evolution decades before the concepts it pioneered—homology, burden, the imitative epigenotype—reached the agenda of evolutionary biology. This paper reconstructs the lineages that operationalized his insights across several fields and explores the internal and external reasons for ...

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

Journal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

A new piece in the puzzle: The palaeoecological significance of bryozoans over 7000 years in Daidokutsu Cave (Okinawa, Japan)

Journal of Quaternary Science, EarlyView.
ABSTRACT Submarine caves are cryptic, climatically sensitive habitats with long‐term ecological dynamics that are poorly understood. We present the first palaeoecological analysis of bryozoans from Daidokutsu Cave (Okinawa, Japan), based on a sediment core spanning approximately the last 7000 years.

Cryptic diversity within two widespread diadromous freshwater fishes (Teleostei: Galaxiidae)

Ecology and Evolution
Identification of taxonomically cryptic species is essential for the effective conservation of biodiversity. Freshwater‐limited organisms tend to be genetically isolated by drainage boundaries, and thus may be expected to show substantial cryptic ...

Explanatory essentialism and cryptic species

European Journal for Philosophy of Science
Abstract Explanatory Essentialism (EE) is the view that a property is the essence of a kind because it causally explains the many properties that instances of the kind exhibit. This paper examines an application of EE to biological species, which I call Biological Explanatory Essentialism (BEE).
