April 2020 | The Marine Biologist 03 In brief Metal-Organic Framework material is a potent pollutant extractor Researchers in Spain have developed a new material that can soak up pollution from water. The substance can remove microplastics, dyes and other pollutants from water, and could find applications in detecting and monitoring pollution. It is a type of metal- organic framework (MOF), an organic- inorganic hybrid crystalline material with a porous, cage-like structure and an enormous surface area (in the case of some MOFs more than 7,000 square metres per gram). Its magnetic properties allow it to be extracted from water along with adsorbed contaminants. It is chemically stable and easy to clean and reuse. A team of chemists led by Gemma Turnes at Mallorca’s University of the Balearic Islands (UIB) synthesized the substance, and published their results in the journal ACS Applied Materials & Interfaces. Those hoping for a magic clean-up of our seas may be in for a bit of a wait: Dr Turnes said ‘These are preliminary results and the material has not been tested on real Pillar coral (Dendrogyra cylindrus), a species highly susceptible to stony coral tissue loss samples yet.

Summary In cnidarians, axial patterning is not restricted to embryonic development but continues throughout a prolonged life history filled with unpredictable environmental changes. How this developmental capacity copes with fluctuations of food availability and whether it recapitulates embryonic mechanisms remain poorly understood. To address these questions, we utilize the tentacles of the sea anemone Nematostella vectensis as a novel paradigm for developmental patterning across distinct life history stages.

Here we utilize the tentacles of the sea anemone Nematostella vectensis as an experimental paradigm for developmental patterning across distinct life history stages. By analyzing over 1000 growing polyps, we find that tentacle progression is stereotyped and occurs in a feeding-dependent manner. Using a combination of genetic, cellular and molecular approaches, we demonstrate that the crosstalk between Target of Rapamycin (TOR) and Fibroblast growth factor receptor b (Fgfrb) signaling in ring muscles defines tentacle primordia in fed polyps. Interestingly, Fgfrb-dependent polarized growth is observed in polyp but not embryonic tentacle primordia. These findings show an unexpected plasticity of tentacle development, and link post-embryonic body patterning with food availability. 1 Developmental Biology Unit, European Molecular Biology Laboratory, 69117 Heidelberg, Germany. 2 Stowers Institute for Medical Research, Kansas City, MO 64110,

  • Lerner's Concept of Developmental Homeostasis and the Problem of Heterozygosity Level in Natural Populations
    Heredity 55 (1985) 341—353 The Genetical Society of Great Britain Received 20 March 1985 Lerner's concept of developmental homeostasis and the problem of heterozygosity level in natural populations G. Livshits and E. Kobyliansky Department of Anatomy and Anthropology, Sackler Faculty of Medicine, Tel Aviv University, Ramat Aviv, Israel. In recent years adherents of the neutral mutation hypothesis have conducted a variety of statistical tests concerning the applicability of their theory to data of biochemical genetic polymorphism in natural populations. From the other side, the involvement of natural selection as a main evolutionary force responsible for the observed levels of polymorphism and heterozygosity have also been proposed in numerous field studies and theoretical considerations. However, none of these hypotheses completely and satisfactorily explains the collected data. We believe that one of the main causes of the discrepancy in theories is that the variability at each locus is considered independently in both of the above- mentioned approaches. Yet, it was suggested long ago, and now there is an increasing amount of evidence indicating cooperation between different loci which can influence the variability at each of them. Thus we think that the use of models considering the genome as a suit of independent genes is a priori expected to decrease the efficacy of the approximation. In the present review we attempt to draw attention to findings of interdependence of the variability of different characters and its possible limiting action on the growth of genetic diversity in natural populations. We do not try to give a universal explanation for the processes acting in populations and determining levels of heterozygosity.

  • Visual Fields in Hornbills: Precision-Grasping and Sunshades
    Ibis (2004), 146, 18–26 Blackwell Publishing Ltd. Visual fields in hornbills: precision-grasping and sunshades GRAHAM R. MARTIN1* & HENDRI C. COETZEE2 1School of Biosciences, The University of Birmingham, Edgbaston, Birmingham B15 2TT, UK 2Ground Hornbill Research and Conservation Project, Private Bag X1644, Warmbaths, 0480, Republic of South Africa Retinal visual fields were determined in Southern Ground Hornbills Bucorvus leadbeateri and Southern Yellow-billed Hornbills Tockus leucomelas (Coraciiformes, Bucerotidae) using an ophthalmoscopic reflex technique. In both species the binocular field is relatively long and narrow with a maximum width of 30° occurring 40° above the bill. The bill tip projects into the lower half of the binocular field. This frontal visual field topography exhibits a number of key features that are also found in other terrestrial birds. This supports the hypothesis that avian visual fields are of three principal types that are correlated with the degree to which vision is employed when taking food items, rather than with phylogeny. However, unlike other species studied to date, in both hornbill species the bill intrudes into the binocular field. This intrusion of the bill restricts the width of the binocular field but allows the birds to view their own bill tips. It is suggested that this is associated with the precision-grasping feeding technique of hornbills. This involves forceps-like grasping and manipulation of items in the tips of the large decurved bill. The two hornbill species differ in the extent of the blind area perpendicularly above the head. Interspecific comparison shows that eye size and the width of the blind area above the head are significantly cor- related.

  • African Gray Hornbill Class: Aves
    Tockus nasutus nasutus African Gray Hornbill Class: Aves. Order: Coraciiformes. Family: Bucerotidae. Other names: Gray hornbill, hornbill Physical Description: Male—dun-colored with a central light stripe from hind neck to rump; head, throat, neck more or less gray with a broad white stripe over eye to nape; wing feathers and coverts (feathers covering the bases of the quills of the wings and tail) edged with whitish; outer tail feathers tipped white; underside creamy white; bill black with a splash of cream at base of upper mandible. Female—smaller, bill is colored red at tip, and greater part of the upper mandible is yellow. Hornbills are about 18 inches, males being larger than females. The wingspan of the gray hornbill is 7.5- 10 inches and weighs 5-9oz. Diet in the Wild: bird eggs and nestlings, insects, rodents, lizards, frogs, supplemented with small fruit and seeds especially during the dry season. Diet at the Zoo: Apples, papayas, grapes, hard-boiled eggs, mealworms, softbill diet, pinkie mice Habitat & Range: Sub-Saharan and Eastern Africa into Arabia, living in open woodlands and tree hollows Life Span: Up to 25 years Perils in the wild: Birds of prey, some carnivores, man, habitat destruction Physical Adaptations: Hornbills have huge, two-tiered beaks that cause the birds to appear top-heavy. The bill is long forming dexterous forceps. The cutting edges are serrated for breaking up food. The casque surmounting the bill is a narrow ridge that may reinforce the upper mandible. In spite of its heavy appearance, the structure is a light skin of keratin overlying a bony support.

  • THE Fungus FILES 31 REPRODUCTION & DEVELOPMENT
    Reproduction and Development SPORES AND SO MUCH MORE! At any given time, the air we breathe is filled with the spores of many different types of fungi. They form a large proportion of the “flecks” that are seen when direct sunlight shines into a room. They are also remarkably small; 1800 spores could fit lined up on a piece of thread 1 cm long. Fungi typically release extremely high numbers of spores at a time as most of them will not germinate due to landing on unfavourable habitats, being eaten by invertebrates, or simply crowded out by intense competition. A mid-sized gilled mushroom will release up to 20 billion spores over 4-6 days at a rate of 100 million spores per hour. One specimen of the common bracket fungus (Ganoderma applanatum) can produce 350 000 spores per second which means 30 billion spores a day and 4500 billion in one season. Giant puffballs can release a number of spores that number into the trillions. Spores are dispersed via wind, rain, water currents, insects, birds and animals and by people on clothing. Spores contain little or no food so it is essential they land on a viable food source. They can also remain dormant for up to 20 years waiting for an opportune moment to germinate. WHAT ABOUT LIGHT? Though fungi do not need light for food production, fruiting bodies generally grow toward a source of light. Light levels can affect the release of spores; some fungi release spores in the absence of light whereas others (such as the spore throwing Pilobolus) release during the presence of light.

    Basic Biological Principles Biology = The study of Life Characteristics of Life Complex Organization Metabolism (Energy Flow) Homeostasis Reproduction and Heredity Growth and Development Response to Stimuli Sample Question A virus consists of a single strand of DNA enclosed in a protein capsule. Is a virus considered a living organism? A. Yes; since the virus contains protein, it is a living organism. B. Yes; since the virus contains DNA, it is a living organism. C. No; living organisms must have two characteristics of life, and the T4 bacteriophage only has one. D. No; viruses are not considered to be living organisms. Answer: D All living organisms must have an organized structure, obtain and use energy and materials, maintain homeostasis, grow, reproduce and pass on genetic information, and respond to stimuli and evolve/adapt to their environment. Although viruses contain DNA and pass their DNA on to their offspring, they cannot do this unassisted, nor do they meet all the other criteria for living organisms. Thus, viruses are not considered to be living organisms. Complex Organization Everything in the world is made up of matter and all matter is made up of atoms Elements = consist of only one kind of atom Compounds = two or more elements combined Living organisms are composed of many different organic (carbon-based) and inorganic compounds Cells = composed of many different compounds, basic building blocks of life Sample Question What is the single most abundant compound in living organisms?
