Article Reference Fishing at the Late Islamic settlement in Kharā’ib al-Dasht, Failaka Island, Kuwait
The Kharā’ib al-Dasht settlement, located on the north-eastern coast of the island of Failaka in Kuwait, has been excavated systematically since 2013 by the Kuwaiti-Polish Archaeological Mission. The investigated area yielded remains dated to the Late Islamic period, from the late seventeenth to the nineteenth century. In the northernmost part of the site, a fish processing area was uncovered, while the remains of residential structures (houses 1 and 2), as well as a mosque, were discovered in the eastern part of the site. Concentrations of fireplaces, hearths and ovens were discovered inside the houses and courtyards of what seems to be the centre of the settlement as well as from the periphery of the site. Fishing was evidenced not only by the presence of fish bones but also by recovered fishing technologies, including the remains of stone fish traps that were discovered in the coastal waters near to the site. The excavations yielded 12,182 bones of marine fishes. Twenty eight families are represented, including six families of cartilaginous fishes. Ariidae bones were most numerous followed by Haemulidae,Sciaenidae and Carcharhinidae. The analysis of the assemblage shows that fishing could have been of great importance to the inhabitants of the settlement. Moreover, we attest different patterns in the fish assemblages between the two different parts of the village. The fish processing area can be seen as a workplace, while the daily activity took place in the village. These differences can also be used to shed light on the fishing techniques these people used.

Article Reference Fitness-heterozygosity associations differ between male and female winter moths Operophtera brumata L.
The association between heterozygosity and fitness is positive but weak on average and varies between studies. inbreeding has been invoked as the driving force between the positive heterozygosity-fitness associations, yet in spatio-temporally stable environments a negative correlation is expected. Furthermore, different patterns can arise because of the effects of natural selection on different loci and variation can be expected among groups of individuals that experience different levels of stress. In this paper we report on fitness-heterozygosity associations in the winter moth for six allozyme loci. The relationship is estimated for males and females separately, in four areas differing in their degree of fragmentation, and variation among loci is modelled. We introduce a linear mixed model framework to achieve this analysis. This approach differs from more traditional (multiple) regression analyses and allows testing specific interactions. We show that fitness, as estimated by body size, is negatively correlated with heterozygosity, but only so in females. This association does not vary significantly among loci and the four areas. We speculate that a trade-off between fitness-consequences of inbreeding and outbreeding at different stages of the winter moth life cycle could explain the observed patterns.

Article Reference Five New Species of Homoscleromorpha (Porifera) from the Caribbean Sea
Five new species of Homoscleromorpha (Porifera) of four genera, Oscarella, Plakortis, Plakina and Corticium, are described from vertical walls of reef caves at depths ranging from 23 to 28 m in the Caribbean Sea. Oscarella nathaliae sp. nov. has a leaf-like thinly encrusting, flat body, loosely attached to the substrate and a perforated, not lobate surface. Oscarella nathaliae sp. nov. contains two bacterial morphotypes and is characterized by two mesohylar cell types with inclusions. Plakortis myrae sp. nov. has diods of two categories: abundant large ones (83–119 mm long) and rare small ones (67–71 mm long) with sinuous, S-bent centres; triods Y- or T-shaped (18–5 mm long), and abundant microrhabds (5–12 mm long). Plakortis edwardsi sp. nov. has diods of one category with thick, sinuous, S-bent centres (110 to 128 mm long); triods T-shaped (actines 28–59 mm long). It is the only species of this genus showing small diods (22–31 mm long). Plakortis dariae sp. nov. has diods of two categories: large ones (67–112 mm long) and small, rare, irregular ones, slightly curved, often deformed with one end blunt (30–59 mm long); triods rare and regular (actines 20–44 mm long long). Corticium diamantense sp. nov. has oscula situated near its border, regular non-lophose calthrops of one size class, very rare tetralophose calthrops and candelabra with the fourth actine ramified basally in 4–5 microspined rays. In addition, a re-description of Plakina jamaicensis Lehnert & van Soest 1998 is based on newly collected material and the type specimen. P. jamaicensis has a convoluted brainlike surface; well developed sub-ectosomal cavities; irregular sinuous diods, triods, calthrops, rare monolophose calthrops, rare dilophose calthrops, rare trilophose calthrops and common tetralophose calthrops. Molecular ‘barcoding’ sequences for mitochondrial cob are given for Plakortis edwardsi sp. nov., P. dariae sp. nov., Plakina jamaicensis and Corticium diamantense sp. nov. An identification key for all western Atlantic Homoscleromorpha is provided.

Article Reference Flabellopteris lococannensis gen. et sp. nov.: A new fern-like plant from the Famennian of South Africa
A new fossil plant, Flabellopteris lococannensis Gess and Prestianni gen. et sp. nov., is described from the Famennian of South Africa. This plant is interpreted as monopodial in habit with a first order axis that only occasionally dichotomizes. The lateral organs (both branches and appendages) are borne spirally on all branching orders and a 1/3 organotaxy is suggested. The first order axes bear both second order axes and fertile appendages at the same nodes. Axes of the second and third branching orders bear appendages made of several isotomous dichotomies. Recurved paired sporangia are borne on dichotomizing appendages that are like the vegetative appendages. The plant bears some similarity to the Iridopteridales but also to the Late Devonian Rhacophytales and to the Lower Carboniferous fernlike plant Chlidanophyton dublinensis. The architecture of the plant is briefly discussed and its implication on the evolution of the frond is considered.

Article Reference Flocculation with heterogeneous composition in water environments: A review
Flocculation is a key process for controlling the fate and transport of suspended particulate matter (SPM) in water environments and has received considerable attention in the field of water science (e.g., oceanography, limnology, and hydrology), remaining an active area of research. The research on flocculation has been con­ducted to elucidate the SPM dynamics and to diagnose various environmental issues. The flocculation, sedi­mentation, and transportation of SPM are closely linked to the compositional and structural properties of flocs. In fact, flocs are highly heterogeneous in terms of composition. However, the lack of comprehensive research on floc composition and structure has led to misconceptions regarding the temporal and spatial dynamics of SPM. This review summarizes the current understanding of the heterogeneous composition of flocs (e.g., minerals, organic matter, metals, microplastic, engineered nanoparticles) and its effect on their structure and on their fate and transport within aquatic environments. Furthermore, the effects of human activities (e.g., pollutant discharge, construction) on floc composition are discussed.

Article Reference Flora and fauna from a new Famennian (Upper Devonian) locality at Becco, eastern Belgium
The Becco locality (Liège province), belongs to the Theux tectonic window and represents a proximal, probably fluvial, environment corresponding to a channel infill. We present here a preliminary report of the fossil assemblage discovered at the locality. The Becco site has yielded a diverse flora of early seed plants including Moresnetia zalesskyi, Dorinnotheca streeli and Condrusia sp. This assemblage, characteristic of the Belgian Famennian, highlights the diversity of early spermatophytes in the country. Becco has also delivered a rich vertebrate fauna with antiarch, groenlandaspid and phyllolepid placoderms, diplacanthiform acanthodians, as well as actinopterygians and various sarcopterygians. The fossiliferous assemblage of Becco resembles those of several Devonian tetrapod- bearing localities, including that of Strud in Belgium, and could therefore provide a favorable palaeoecological setting in the search for early tetrapods.
