Article Synopsis
  • Portugal has a lot of different plants and animals because of its unique geography and history, but these species are in danger from things like climate change and over-exploitation.
  • Researchers in Portugal are working together through a project called Biogenome Portugal to study and document biodiversity, which means looking closely at the genes of different species.
  • The goal is to create a library of genetic information to help protect endangered species and promote conservation efforts in Portugal, especially for unique plants and animals found only there.

Ticks are blood-sucking arthropods that can transmit pathogens to their host. As insular ecosystems can enhance tick-host interactions, this study aimed to understand tick diversity, pathogen presence, and their respective associations in the Azores and Madeira archipelagos. Unfed or partially engorged ticks (n = 120) were collected from 58 cats and dogs in the Azores (n = 41 specimens) and Madeira (n = 79 specimens) from November 2018 to March 2019.

Article Synopsis
  • The Bermuda petrel is a critically endangered seabird that has faced significant population decline since human settlement in Bermuda, nearing extinction.
  • Since the 1950s, conservation efforts have helped the population recover, but threats such as genetic issues from inbreeding and genetic drift remain.
  • Genetic analysis shows the petrel experienced a bottleneck, with low mitochondrial diversity but similar nuclear diversity to other petrels; however, individual inbreeding doesn't seem to influence hatching success or mate choice.

Background: Sea-lavenders (Limonium Mill., Plumbaginaceae) are a cosmopolitan group of diploid and polyploid plants often adapted to extreme saline environments, with a mostly Tethyan distribution, occurring in the Mediterranean, Irano-Turanian, Euro-Siberian and in the New World. The halophylic Limonium vulgare polyploid complex in particular, presents a large distribution throughout extreme salt-marsh habitats and shows little morphological but high taximetric variation, frequently blurring species delimitation.

The White Sands lizards of New Mexico are a rare and classic example of convergent evolution where three species have evolved blanched coloration on the white gypsum dunes. Until now, no geological replicate of the pattern had been described. However, one of the White Sands species, the lesser earless lizard (), has been discovered to also inhabit the Salt Basin Dunes of Texas, where it has also evolved a blanched morph.

L. is a sclerophyllous tree species native to the western Mediterranean, a region that is considered highly vulnerable to increased temperatures and severe dry conditions due to environmental changes. Understanding the population structure and demographics of is essential in order to anticipate whether populations at greater risk and the species as a whole have the genetic background and reproductive dynamics to enable rapid adaptation.

Understanding patterns of population differentiation and gene flow in insect vectors of plant diseases is crucial for the implementation of management programs of disease. We investigated morphological and genome-wide variation across the distribution range of the spittlebug (Linnaeus, 1758) (Hemiptera, Auchenorrhyncha, Aphrophoridae), presently the most important vector of the plant pathogenic bacterium Wells et al., 1987 in Europe.

Background: People with visual impairment have benefitted from recent developments of assistive technology that aim to decrease socio-economic inequality. However, access to post-secondary education is still extremelly challenging, especially for scientific areas. The under representation of people with visual impairment in the evolution research community is connected with the vision-based communication of evolutionary biology knowledge and the accompanying lack of multisensory alternatives for learning.

Article Synopsis
  • Climate change is affecting cork oak trees, which are important species in their environment.
  • Scientists studied how these trees adapt to their locations by looking at their genetics across different areas in the Mediterranean.
  • Their research found that some areas are more at risk from climate change, helping us understand how to better protect and manage cork oak forests.

Following publication of the original article [1], it has been brought to the authors' attention that in their paper (Rodrigues et al. 2016) they reported the genome size based on 2C values (diploid genome) when it is more common to present it as 1C value.

Article Synopsis
  • Human-mediated introductions of species, like bumblebees used for crop pollination, can harm native ecosystems through hybridization, affecting native pollinators.
  • In Portugal, researchers studied the genetic interactions between commercial bumblebees and local Iberian subspecies using mitochondrial DNA and genomic data, finding signs of hybridization.
  • They recommend that farmers properly dispose of used hive boxes to prevent escapees from interfering with native populations and suggest evaluating the use of local bumblebee subspecies for pollination instead.

Species respond to global climatic changes in a local context. Understanding this process, including its speed and intensity, is paramount due to the pace at which such changes are currently occurring. Tree species are particularly interesting to study in this regard due to their long generation times, sedentarism, and ecological and economic importance.

Structure_threader is a program to parallelize multiple runs of genetic clustering software that does not make use of multithreading technology (structure, fastStructure and MavericK) on multicore computers. Our approach was benchmarked across multiple systems and displayed great speed improvements relative to the single-threaded implementation, scaling very close to linearly with the number of physical cores used. Structure_threader was compared to previous software written for the same task-ParallelStructure and StrAuto and was proven to be the faster (up to 25% faster) wrapper under all tested scenarios.

Background: Colour polymorphisms are common among animal species. When combined with genetic and ecological data, these polymorphisms can be excellent systems in which to understand adaptation and the molecular changes underlying phenotypic evolution. The meadow spittlebug, Philaenus spumarius (L.

Background: Next-generation sequencing datasets are becoming more frequent, and their use in population studies is becoming widespread. For non-model species, without a reference genome, it is possible from a panel of individuals to identify a set of SNPs that can be used for further population genotyping. However the lack of a reference genome to which the sequenced data could be compared makes the finding of SNPs more troublesome.

Background: The process of generating raw genome sequence data continues to become cheaper, faster, and more accurate. However, assembly of such data into high-quality, finished genome sequences remains challenging. Many genome assembly tools are available, but they differ greatly in terms of their performance (speed, scalability, hardware requirements, acceptance of newer read technologies) and in their final output (composition of assembled sequence).

Philaenus spumarius, widely studied for its colour/pattern polymorphism, is a widespread species across the Holartic. The patterns of haplotype divergence at the mitochondrial gene cytochrome oxidase I (COI) found in this study suggest a postglacial western Europe (Iberian and Italian peninsulas to Britain) and a eastern (from Near East to Finland) south-to-north colonization. The haplotypes found in North America are most likely derived from the British haplotypes.

concatenator is a simple and user-friendly software that implements two very useful functions for phylogenetics data analysis. It concatenates NEXUS files of several fragments in a single NEXUS file ready to be used in phylogenetics software, such as paup and mrbayes and it converts FASTA sequence data files to NEXUS and vice-versa. Additionally, concatenated files can be prepared for partition tests in paup.
