Cryptic matters: overlooked species generate most butterfly beta-diversity

This is a Forum paper in Ecography that intends to demonstrate (and hopefully foster the discussion on) the importance of including the cryptic diversity in ecological, biodiversity and biogeographic studies to avoid biased results. Cryptic species are frequently ignored in large-scale studies and monitoring programs. However, it is unknown if this could represent a bias extending beyond the number of missed species.

Discovered just before extinction? The first endemic ant from the Balearic Islands is endangered by climate change

It is not uncommon to think that mountain summits cannot host interesting biodiversity. In some cases, species can find their place in such inhospitable habitats. This is the story of the newly discovered ant species Lasius balearicus, the first endemic ant from the Balearic Islands.

A role for Taiman in metamorphosis

Recently, the transcription factor Methoprene-tolerant (Met) has been reported to be the JH receptor in the context of insect metamorphosis. Further experiments in vitro suggested that Met did not act alone as the JH receptor, but had to heterodimerise with the protein Taiman. Researchers have discovered that Taiman is expressed in a number of isoforms, and selective depletion has shown that at least some of these are involved in transducing the JH signal that represses metamorphosis.

Developmental constraints in cave beetles

Subterranean beetles of the tribe Leptodirini show a wide range of life cycle modifications, including a reduced number of larval instars, an increase in egg size and a reduction in their number per clutch. In this work researchers show that, unexpectedly, developmental timing and duration are highly conserved among species irrespective of these life cycle modifications.

Concept, application and bioinformatic tools to be able to work with Genotype networks

Genotype networks are a concept used in the field of systems biology to study the ''evolvability'' or ''innovability'' of a set of genotypes having the same, broadly defined, phenotype, such as viability, and to determine whether a given phenotype is robust to mutations. In two different publications researchers describe the concept, application and the bioinformatic tools to be able to work with them.

Specification of Differentiated Adult Progenitors via Inhibition of Endocycle Entry in the Drosophila Trachea

In this paper researchers have identified the mechanism that controls the genetic determination of progenitors adult cells versus larval cells.  Drosophila tracheal system consist of  a population of  adult trachea progenitor cells arises from differentiated cells of the larval main trachea that retain the ability to reenter the cell cycle and give rise to the multiple adult tracheal cell types.

Multilocus molecular systematics and evolution in time and space of Calligrapha

In this article Gómez Zurita tells the story of a lineage of leaf beetles that originated in the Late Miocene, some 10 Ma ago, in arid, open vegetation environments of the most meridional latitudes of the large island-continent that was North America at the time. Ref. Art. Montelongo, T. & Gómez-Zurita, J. (2014). Zoologica Scripta, 43, 605-62.
