Note on the association between Plakobranchus ocellatus (Mollusca: Gastropoda: Opisthobranchia) and Holothuria atra (Echinodermata: Holothuroidea)

description: This paper presents evidence of a commensal association between an opisthobranch (Plakobranchus ocellatus)
 and a sea cucumber (Holothuria atra). Field observations revealed that occurrences of P. ocellatus specimens and egg fil-
 aments were much more frequent on the body wall of H. atra than on that of two other holothurian species living in the
 same habitat. Roughly 95% of H. atra were colonized by P. ocellatus during the night, which corresponds to the active
 period of H. atra and the resting period of P. ocellatus. The proportion decreased to ca. 21% in the daytime when sea
 cucumbers are resting and most opisthobranchs are foraging. Laboratory trials confirmed the daily pattern of association
 and the fact that P. ocellatus lay their eggs on the body wall of H. atra. Furthermore, multiple-choice experiments showed
 that ca. 71% of P. ocellatus favoured H. atra, whereas only ca. 9% colonised other species of sea cucumber. Because H.
 atra is known to exude toxic chemicals that deter several species of invertebrates and fishes, the opisthobranch may use the
 sea cucumber as a refuge against predators and as a secure spawning ground.

description: Plants use sophisticated strategies to balance responses to oxidative stress. Programmed cell death, including the hypersensitive response (HR) associated with successful pathogen recognition, is one cellular response regulated by reactive oxygen in various cellular contexts. The Arabidopsis basic leucine zipper (bZIP) transcription factor AtbZIP10 shuttles between the nucleus and the cytoplasm and binds consensus G- and C-box DNA sequences. Surprisingly, AtbZIP10 can be retained outside the nucleus by LSD1, a protein that protects Arabidopsis cells from death in the face of oxidative stress signals. We demonstrate that AtbZIP10 is a positive mediator of the uncontrolled cell death observed in lsd1 mutants. AtbZIP10 and LSD1 act antagonistically in both pathogen-induced HR and basal defense responses. LSD1 likely functions as a cellular hub, where its interaction with AtbZIP10 and additional, as yet unidentified, proteins contributes significantly to plant oxidative stress responses.

description: The digestive tract of seven species of Turridae (Lora rufa, Mangelia costulata, M. coarctata, M. nebula, Philbertia linearis, Ph. purpurea, Haedropleura septangularis) has been the object of morphological, histological and histochimical studies. Its structure, compared to Stenoglossa (Muricoidea, Buccinoidea, Volu- toidea), appears much simpler.
There is a strong reduction of the salivary glands and of the stomach wich has only retained the typhlosolis as ancestral structure. The poison gland is similar to that found in Conidae and Terebridae. It disappears in Philbertia linearis where the radula and the salivary glands are also missing.
Attention has been focused on the anterior part of the digestive tract and an evolutive scheme of the proboscis of Toxoglossa is proposed. It appears that Toxoglossa originated independently of Stenoglossa, from a group possessing an acrembolic proboscis.

description: Telomeric DNA can fold into four-stranded structures known as G-quadruplexes. Here we investigate the ability of G-quadruplex DNA to serve as a substrate for recombinant Tetrahymena and native Euplotes telomerase. Inter- and intramolecular G-quadruplexes were gel-purified and their stability examined using native gel electrophoresis, circular dichroism (CD) and thermal denaturation. While intermolecular G-quadruplexes were highly stable, they were excellent substrates for both ciliate telomerases in primer extension assays. In contrast, intramolecular G-quadruplexes formed in K+ exhibited biphasic unfolding and were not extended by ciliate telomerases. Na+-stabilised intramolecular G-quadruplexes were extended by telomerase owing to their rapid rate of dissociation. The Tetrahymena telomerase protein component bound to inter- but not intramolecular K+-stabilised G-quadruplexes. This study provides evidence that parallel intermolecular G-quadruplexes can serve as substrates for telomerase in vitro, their extension being mediated through direct interactions between this higher-order structure and telomerase.

description: We present the SLoWPoKES-II catalog of low-mass visual binaries identified from the Sloan Digital Sky Survey by matching photometric distances. The candidate pairs are vetted by comparing the stellar density at their respective Galactic positions to Monte Carlo realizations of a simulated Milky Way. In this way, we are able to identify large numbers of bona fide wide binaries without the need of proper motions. 105,537 visual binaries with angular separations of $\sim$1-20", are identified, each with a probability of chance alignment of $\lesssim$5%. This is the largest catalog of bona fide wide binaries to date, and it contains a diversity of systems---in mass, mass ratios, binary separations, metallicity, and evolutionary states---that should facilitate follow-up studies to characterize the properties of M dwarfs and white dwarfs. There is a subtle but definitive suggestion of multiple populations in the physical separation distribution, supporting earlier findings. We suggest that wide binaries are comprised of multiple populations, most likely representing different formation modes. There are 141 M7 or later wide binary candidates, representing a 7-fold increase in the number currently known. These binaries are too wide to have been formed via the ejection mechanism. Finally, we find that ~6% of spectroscopically confirmed M dwarfs are not included in the SDSS STAR catalog; they are misclassified as extended sources due to the presence of a nearby or partially resolved companion. The SLoWPoKES-II catalog is publicly available to the entire community on the world wide web via the Filtergraph data visualization portal.

description: Previous work links histone methylation by Set2 with transcriptional elongation. yFACT (Spt16–Pob3 and Nhp6) reorganizes nucleosomes and functions in both transcriptional initiation and elongation. We show that growth defects caused by spt16 or pob3 mutations can be suppressed by deleting SET2, suggesting that Set2 and yFACT have opposing roles. Set2 methylates K36 of histone H3, and K36 substitutions also suppress yFACT mutations. In contrast, set1 enhances yFACT mutations. Methylation at H3 K4 by Set1 is required for set2 to suppress yFACT defects. We did not detect an elongation defect at an 8 kb ORF in yFACT mutants. Instead, pob3 mutants displayed reduced binding of both pol II and TBP to the GAL1 promoter. Importantly, both GAL1 transcription and promoter binding of pol II and TBP are significantly restored in the pob3 set2 double mutant. Defects caused by an spt16 mutation are enhanced by either TBP or TFIIA mutants. These synthetic defects are suppressed by set2, demonstrating that yFACT and Set2 oppose one another during transcriptional initiation at a step involving DNA binding by TBP and TFIIA.

description: Conserved domains within the RNA component of telomerase provide the template for reverse transcription, recruit protein components to the holoenzyme and are required for enzymatic activity. Among the functionally essential domains in ciliate telomerase RNA is stem-loop IV, which strongly stimulates telomerase activity and processivity even when provided in trans. The NMR structure of Tetrahymena thermophila stem-loop IV shows a highly structured distal stem-loop linked to a conformationally flexible template-proximal region by a bulge that severely kinks the entire RNA. Through extensive structure–function studies, we identify residues that contribute to both these structural features and to enzymatic activity, with no apparent effect on the binding of TERT protein. We propose that the bending induced by the GA bulge and the flexibility of the template-proximal region allow positioning of the prestructured apical loop during the catalytic cycle.

description: About half of the elements beyond iron are synthesized in stars by rapid-neutron capture process (r-process). The stellar environment provides very high neutron flux in a short time ($\sim$ seconds) which is conducive for the creation of progressively neutron-rich nuclei till the waiting point is reached after which no further neutron capture reactions proceed. At this point such extremely neutron-rich nuclei become stable via $β^-$ decay. A detailed understanding of the r-process remains illusive. In the present work, we explore the radiative neutron-capture (n,$γ$) cross sections and reaction rates around the r-process peak near mass number eighty. The inherent uncertainties remain large in some cases, particularly in case of neutron-rich nuclei. When the low-energy enhancement exists, it results in significant increase in the reaction rate for neutron-capture.

description: We propose a new mechanism to suppress the axion isocurvature perturbation, while producing the right amount of axion dark matter, within the framework of supersymmetric axion models with the axion scale induced by supersymmetry breaking. The mechanism involves an intermediate phase transition to generate the Higgs μ-parameter, before which the weak scale is comparable to the axion scale and the resulting stronger QCD yields an axion mass heavier than the Hubble scale over a certain period. Combined with that the Hubble-induced axion scale during the primordial inflation is well above the intermediate axion scale at present, the stronger QCD in the early Universe suppresses the axion fluctuation to be small enough even when the inflationary Hubble scale saturates the current upper bound, while generating an axion misalignment angle of order unity.

description: Transcription factors with identical DNA-binding specificity often activate different genes in vivo. Yeast Ace2 and Swi5 are such activators, with targets we classify as Swi5-only, Ace2-only, or both. We define two unique regulatory modes. Ace2 and Swi5 both bind in vitro to Swi5-only genes such as HO, but only Swi5 binds and activates in vivo. In contrast, Ace2 and Swi5 both bind in vivo to Ace2-only genes, such as CTS1, but promoter-bound Swi5 fails to activate. We show that activation by Swi5 is prevented by the binding of the Forkhead factors Fkh1 and Fkh2, which recruit the Rpd3(Large) histone deacetylase complex to the CTS1 promoter. Global analysis shows that all Ace2-only genes are bound by both Ace2 and Swi5, and also by Fkh1/2. Genes normally activated by either Ace2 or Swi5 can be converted to Ace2-only genes by the insertion of Fkh-binding sites. Thus Fkh proteins, which function initially to activate SWI5 and ACE2, subsequently function as Swi5-specific antiactivators.

description: Regulators of G-protein signaling (RGS proteins) negatively regulate heterotrimeric G-protein cascades that enable eukaryotic cells to perceive and respond to external stimuli. The rice-blast fungus Magnaporthe grisea forms specialized infection structures called appressoria in response to inductive surface cues. We isolated Magnaporthe RGS1 in a screen for mutants that form precocious appressoria on non-inductive surfaces. We report that a thigmotropic cue is necessary for initiating appressoria and for accumulating cAMP. Similar to an RGS1-deletion strain, magAG187S (RGS-insensitive Gαs) and magAQ208L (GTPase-dead) mutants accumulated excessive cAMP and elaborated appressoria on non-inductive surfaces, suggesting that Rgs1 regulates MagA during pathogenesis. Rgs1 was also found to negatively regulate the Gαi subunit MagB during asexual development. Deficiency of MAGB suppressed the hyper-conidiation defect in RGS1-deletion strain, whereas magBG183S and magBQ204L mutants produced more conidia, similar to the RGS1-deletion strain. Rgs1 physically interacted with GDP·AlF4−-activated forms of MagA, MagB and MagC (a GαII subunit). Thus, Rgs1 serves as a negative regulator of all Gα subunits in Magnaporthe and controls important developmental events during asexual and pathogenic development.
Rediscovery of Coryne fucicola (de Filippi, 1866) (Cnidaria: Hydrozoa)

description: Coryne fucicola (de Filippi, 1866) has been considered a somewhat problematic species of unknown origin and
 whose last records date back more than a century. However, a living colony was recently rediscovered at Roscoff and the
 species is redescribed in this report. It is evidently a valid species and clearly distinct from other similar species like Coryne
 pusilla and C. muscoides. This was also confirmed using 16S sequence data. The relationship to the similarly problematic
 C. vermicularis Hincks, 1866 is discussed and the status of the latter re-evaluated by an examination of the type material.
 Coryne vermicularis appears distinct from C. fucicola, but its relationship to C. pusilla remains unclear. Pending a detailed
 comparison of living material, it is advised not to synonymize C. vermicularis and C. pusilla.

description: For primes $\ell$ and nonnegative integers $a$, we study the partition functions $$p_\ell(a;n):= \#\{λ\vdash n : \text{ord}_\ell(H(λ))=a\},$$ where $H(λ)$ denotes the product of hook lengths of a partition $λ$. These partition values arise as the McKay numbers $m_\ell(\text{ord}_\ell(n!) - a; S_n)$ in the representation theory of the symmetric group. We determine the generating functions for $p_\ell(a;n)$ in terms of $p_\ell(0;n)$ and specializations of specific D'Arcais polynomials. For $\ell = 2$ and $3$, we give an exact formula for the $p_\ell(a;n)$ and prove that these values are zero for almost all $n$. For larger primes $\ell$, the $p_\ell(a;n)$ are positive for sufficiently large $n$. Despite this positivity, we prove that $p_\ell(a;n)$ is almost always divisible by $m$ for any integer $m$. Furthermore, with these results we prove several Ramanujan-type congruences. These include the congruences $$p_\ell(a;\ell^k n - δ(a,\ell)) \equiv 0 \pmod{\ell^{k+1}},$$ for $0

The purpose of the present paper is to find out limiting behaviors of the iterates of the Szász-Mirakyan operator in a probabilistic point of view. We show that the iterates of the Szász-Mirakyan operator uniformly converges to a continuous semigroup generated by a second order degenerate differential operator. A probabilistic interpretation of the convergence in terms of a discrete Markov chain constructed from the iterates and a limiting diffusion process on the half line is captured as well.

description: Regulator of G-protein signaling (RGS) proteins accelerate GTP hydrolysis by heterotrimeric G-protein α subunits and thus inhibit signaling by many G protein-coupled receptors. Several RGS proteins have a multidomain architecture that adds further complexity to their roles in cell signaling in addition to their GTPase-accelerating activity. RGS12 contains a tandem repeat of Ras-binding domains but, to date, the role of this protein in Ras-mediated signal transduction has not been reported. Here, we show that RGS12 associates with the nerve growth factor (NGF) receptor tyrosine kinase TrkA, activated H-Ras, B-Raf, and MEK2 and facilitates their coordinated signaling to prolonged ERK activation. RGS12 is required for NGF-mediated neurite outgrowth of PC12 cells, but not outgrowth stimulated by basic fibroblast growth factor. siRNA-mediated knockdown of RGS12 expression also inhibits NGF-induced axonal growth in dissociated cultures of primary dorsal root ganglia neurons. These data suggest that RGS12 may play a critical, and receptor-selective, role in coordinating Ras-dependent signals that are required for promoting and/or maintaining neuronal differentiation.
Aquilastacus gen. nov. from the southern North Sea and the taxonomic position of Leptastacus operculatus Masry, 1970 (Copepoda: Harpacticoida: Leptastacidae)

description: A new genus of Leptastacidae (Copepoda: Harpacticoida) is described from subtidal sandy sediments in the
 Southern Bight of the North Sea. Aquilastacus serratus gen. nov. sp. nov. is most closely related to Arenocaris Nicholls
 with which it shares the unique sexual dimorphism on the P4 endopod, the distally constricted caudal rami and the loss of
 the subdistal spine on the P3 endopod in the female (and hence of the sexual dimorphism in the male). The genus
 Aquilastacus is more plesiomorphic than Arenocaris in most character states, except for the confluent fifth legs, the absen-
 ce of the outer basal seta on P1 and the presence of only two setae on the female P6. The genus can be readily distinguished
 by the strong serrate plate arising from the anal operculum and the form of the fifth legs in both sexes. The type material
 of Leptastacus operculatus Masry, 1970, previously considered species incertae sedis in the Leptastacidae, is re-examined.
 The only paratype slide labelled as the male proved to contain a female, casting doubts on Masry's (1970) illustrations of
 the male. Based on a detailed redescription of the female, L. operculatus is removed from Leptastacus T. Scott and desi-
 gnated as the type species of a new genus, Stereoxiphos. The new genus holds a transitionary position between
 Belemnopontia Huys and a clade comprising Cerconeotes Huys and Psammastacus Nicholls. It can be distinguished from
 other Leptastacidae by the combination of (1) loss of inner seta on P1 enp-1, (2) pedigerous somites with internal pattern
 of plate-like reinforcements, and (3) anal operculum with very large middorsal projection.

description: This paper describes temporal and seasonal variations in the composition and abundance of the planktonic cope-
 pod community in the North lagoon of Tunis and the influence of selected environmental factors (temperature, salinity, sus-
 pended particulate matter and chlorophyll a concentrations) on this community. Samples were collected weekly from
 March 2001 to September 2002. Total planktonic copepod abundance showed low densities and high variability, lacking
 any clear seasonal pattern. In total, 24 species were identified. According to their occurrence and numerical abundance
 during the study period, Oithona nana, Acartia clausi and Euterpina acutifrons constituted the dominated species of the
 planktonic copepod community in the lagoon. There was a significant correlation between the abundance of copepods and
 environmental factors in the case of Acartia latisetosa, Oithona plumifera, Labidocera brunescens, Euterpina acutifrons,
 Clausocalanus arcuicornis and Corycaeus speciosus.

description: Genomic imprinting is a developmental mechanism that mediates parent-of-origin-specific expression in a subset of genes. How the tissue specificity of imprinted gene expression is controlled remains poorly understood. As a model to address this question, we studied Grb10, a gene that displays brain-specific expression from the paternal chromosome. Here, we show in the mouse that the paternal promoter region is marked by allelic bivalent chromatin enriched in both H3K4me2 and H3K27me3, from early embryonic stages onwards. This is maintained in all somatic tissues, but brain. The bivalent domain is resolved upon neural commitment, during the developmental window in which paternal expression is activated. Our data indicate that bivalent chromatin, in combination with neuronal factors, controls the paternal expression of Grb10 in brain. This finding highlights a novel mechanism to control tissue-specific imprinting.

With the development of convolutional neural networks, the performance of pansharpening methods has been improved, however, the blurry effects and the spectral distortion still exist in their fusion results due to the insufficiency in details learning and the frequency mismatch between MSand PAN. Therefore, the improvement of spatial details at the premise of reducing spectral distortion is still a challenge. In this paper, we propose a frequency-aware fusion network (FAFNet) together with a novel high-frequency feature similarity loss to address above mentioned problems. FAFNet is mainly composed of two kinds of blocks, where the frequency aware blocks aim to extract features in the frequency domain with the help of discrete wavelet transform (DWT) layers, and the frequency fusion blocks reconstruct and transform the features from frequency domain to spatial domain with the assistance of inverse DWT (IDWT) layers. Finally, the fusion results are obtained through a convolutional block. In order to learn the correspondence, we also propose a high-frequency feature similarity loss to constrain the HF features derived from PAN and MS branches, so that HF features of PAN can reasonably be used to supplement that of MS. Experimental results on three datasets at both reduced- and full-resolution demonstrate the superiority of the proposed method compared with several state-of-the-art pansharpening models.

description: This paper aims to make a graph representing an essential skeleton of a character from an image that includes a machine printed or a handwritten character using growing neural gas (GNG) method and relative network graph (RNG) algorithm. The visual system in our brain can recognize printed characters and handwritten characters easily, robustly, and precisely. How does our brain robustly recognize characters? The visual processing in our brain uses the essential features of an object, such as crosses and corners. These features will be helpful for character recognition by a computer. However, extraction of the features is difficult. If the skeleton of a character is represented as a graph, we can more easily extract the features. To extract the skeleton of a character as a graph from an image, this paper proposes the new approach using GNG and RNG algorithm. I achieved to extract skeleton graphs from images including distorted, noisy, and handwritten characters.

description: In this work, we have analytically computed the holographic transport coefficients for (2 + 1)- dimensional strongly coupled field theories, placed in a spatially modulated chemical potential along the x-direction, in the presence of Born-Infeld electrodynamics. We have obtained these coefficients in terms of the black hole horizon data only. We have observed that the Born-Infeld parameter affects these coefficients in a non-trivial way. We have, then, used these results to further study a holographic model for ultra-clean graphene near Dirac point. This is a two current model with an inhomogeneous holographic lattice.

description: Raf kinase inhibitory protein (RKIP) negatively regulates the MAP kinase (MAPK), G protein-coupled receptor kinase-2, and NF-κB signalling cascades. RKIP has been implicated as a metastasis suppressor for prostate cancer, but the mechanism is not known. Here, we show that RKIP inhibits invasion by metastatic breast cancer cells and represses breast tumour cell intravasation and bone metastasis in an orthotopic murine model. The mechanism involves inhibition of MAPK, leading to decreased transcription of LIN28 by Myc. Suppression of LIN28 enables enhanced let-7 processing in breast cancer cells. Elevated let-7 expression inhibits HMGA2, a chromatin remodelling protein that activates pro-invasive and pro-metastatic genes, including Snail. LIN28 depletion and let-7 expression suppress bone metastasis, and LIN28 restores bone metastasis in mice bearing RKIP-expressing breast tumour cells. These results indicate that RKIP suppresses invasion and metastasis in part through a signalling cascade involving MAPK, Myc, LIN28, let-7, and downstream let-7 targets. RKIP regulation of two pluripotent stem cell genes, Myc and LIN28, highlights the importance of RKIP as a key metastasis suppressor and potential therapeutic agent.

description: The growth in lenght and weight of the young Dicentrarchus labrax L. has been studied during two years (1970-1971), involving individuals of groups 0,1 and 2 which were caught in situ. Their growth rates were very high and irregular both within a year and from year to year.
Sea water temperature was recognized to be the main factor in ruling the growth rate; the youngest the fishes were, the most important this effect was.

description: Neutron stars can accumulate asymmetric dark matter (ADM) in their interiors, which affects the neutron star's measurable properties and makes compact objects prime targets to search for ADM. In this work, we use Bayesian inference to explore potential neutron star mass-radius measurements, from current and future x-ray telescopes, to constrain the bosonic ADM parameters for the case where bosonic ADM has accumulated in the neutron star interior. We find that the current uncertainties in the baryonic equation of state do not allow for constraints on the ADM parameter space to be made. However, we also find that ADM cannot be excluded and the inclusion of bosonic ADM in neutron star cores relaxes the constraints on the baryonic equation of state space. If the baryonic equation of state were more tightly constrained independent of ADM, we find that statements about the ADM parameter space could be made. In particular, we find that the high bosonic ADM particle mass ($m_χ$) and low effective self-interaction strength ($g_χ/m_ϕ)$ regime is disfavored due to the observationally and theoretically motivated constraint that neutron stars must have at least a mass of $1 \, \mathrm{M_\odot}$. However, within the remaining parameter space, $m_χ$ and $g_χ/m_ϕ$ are individually unconstrained. On the other hand, the ADM mass-fraction, i.e., the fraction of ADM mass inside the neutron star, can be constrained by such neutron star measurements.

description: The telomerase reverse transcriptase adds de novo DNA repeats to chromosome termini. Here we define Caenorhabditis elegans MRT-1 as a novel factor required for telomerase-mediated telomere replication and the DNA-damage response. MRT-1 is composed of an N-terminal domain homologous to the second OB-fold of POT1 telomere-binding proteins and a C-terminal SNM1 family nuclease domain, which confer single-strand DNA-binding and processive 3′-to-5′ exonuclease activity, respectively. Furthermore, telomerase activity in vivo depends on a functional MRT-1 OB-fold. We show that MRT-1 acts in the same telomere replication pathway as telomerase and the 9-1-1 DNA-damage response complex. MRT-1 is dispensable for DNA double-strand break repair, but functions with the 9-1-1 complex to promote DNA interstrand cross-link (ICL) repair. Our data reveal MRT-1 as a dual-domain protein required for telomerase function and ICL repair, which raises the possibility that telomeres and ICL lesions may share a common feature that plays a critical role in de novo telomere repeat addition.

description: Central noradrenergic signalling mediates arousal and facilitates learning through unknown molecular mechanisms. Here, we show that the β2-adrenergic receptor (β2AR), the trimeric Gs protein, adenylyl cyclase, and PKA form a signalling complex with the AMPA-type glutamate receptor subunit GluR1, which is linked to the β2AR through stargazin and PSD-95 and their homologues. Only GluR1 associated with the β2AR is phosphorylated by PKA on β2AR stimulation. Peptides that interfere with the β2AR–GluR1 association prevent this phosphorylation of GluR1. This phosphorylation increases GluR1 surface expression at postsynaptic sites and amplitudes of EPSCs and mEPSCs in prefrontal cortex slices. Assembly of all proteins involved in the classic β2AR–cAMP cascade into a supramolecular signalling complex and thus allows highly localized and selective regulation of one of its major target proteins.

description: Thermodynamic properties of matter are conveniently expressed as functional relations between variables known as equations of state. Here we experimentally determine the compressibility, density and pressure equations of state for an attractive 2D Fermi gas in the normal phase as a function of temperature and interaction strength. In 2D, interacting gases exhibit qualitatively different features to those found in 3D. This is evident in the normalized density equation of state, which peaks at intermediate densities corresponding to the crossover from classical to quantum behaviour.

description: Despite the length of littorals, studies of annual cycles for phytoplankton in the Mexican Pacific are rare, espe-
 cially in tropical areas. A study of the phytoplankton (basically microphytoplankton) was realized in six locations off the
 States of Jalisco and Colima, from June, 2001 to May, 2002. A total of 286 taxa belonging to the taxonomic groups diatoms,
 dinoflagellates, cyanophyceae and silicoflagellates were identified. The best represented groups were dinoflagellates (157
 taxa) and diatoms (119 taxa). Moreover, the study included a small fraction (15-25 %) of the diatom planktonic flora and
 43% of the dinoflagellate flora from the Mexican Pacific. The flora showed a strong tropical-subtropical affinity.
 Dinoflagellate species appeared to be more important in late spring and early summer, whereas relative abundance of
 diatoms was higher most of the year of study. Five new records of dinoflagellates for the Mexican Pacific are annotated:
 Amphisolenia palmata, Amphisolenia truncata, Gonyaulax jollifei, Kofoidinium splendens and Protoperidinium divarica-
 tum, from which only one is a non-thecate form; these findings may be due to the lack of previous detailed floristic stud-
 ies in the area. No clear relation existed between microplankton and other variables found in the literature, such as
 chlorophyll a and nutrients. However, several patterns of phytoplankton succession were detected during our study: three
 stages were recognized, although they did not correspond with the diversity index values calculated.

description: The diffusion of Neolithic technology together with the Holocene Climatic Optimum fostered the spread of human settlements and pastoral activities in North Africa, resulting in profound and enduring consequences for the dynamics of species, communities and landscapes. Here, we investigate the demographic history of the African wolf (Canis lupaster), a recently recognized canid species, to understand if demographic trends of this generalist and opportunistic carnivore reflect the increase in food availability that emerged after the arrival of the Neolithic economy in North Africa. We screened nuclear and mitochondrial DNA in samples collected throughout Algeria and Tunisia, and implemented coalescent approaches to estimate the variation of effective population sizes from present to ancestral time. We have found consistent evidence supporting the hypothesis that the African wolf population experienced a meaningful expansion concurring with a period of rapid population expansion of domesticates linked to the advent of agricultural practices.
