Intrinsic Lévy behaviour in organisms – searching for a mechanism: Comment on “Liberating Lévy walk research from the shackles of optimal foraging” by A.M. Reynolds
No full textThe seminal papers by Viswanathan and colleagues in the late 1990s [1] and [2] proposed not only that scale-free, superdiffusive Lévy walks can describe the free-ranging movement patterns observed in animals such as the albatross [1], but that the Lévy walk was optimal for searching for sparsely and randomly distributed resource targets [2]. This distinct advantage, now shown to be present over a much broader set of conditions than originally theorised [3], implied that the Lévy walk is a search strategy that should be found very widely in organisms [4]. In the years since there have been several influential empirical studies showing that Lévy walks can indeed be detected in the movement patterns of a very broad range of taxa, from jellyfish, insects, fish, reptiles, seabirds, humans [5], [6], [7], [8], [9] and [10], and even in the fossilised trails of extinct invertebrates [11]. The broad optimality and apparent deep evolutionary origin of movement (search) patterns that are well approximated by Lévy walks led to the development of the Lévy flight foraging (LFF) hypothesis [12], which states that “since Lévy flights and walks can optimize search efficiencies, therefore natural selection should have led to adaptations for Lévy flight foraging”

Monoportula P. A. Sims & D. M. Williams, nov. gen.
No full text<i>Monoportula</i> P.A.Sims & D.M.Williams nov. gen. <p> <b>Registration</b>: http://phycobank.org/103661</p> <p> Type species:— <i>Monoportula uralensis</i> (Strelnikova) P.A.Sims & D.M.Williams nov. comb.</p> <p>Frustules cylindrical, valve face circular, flat. Valve face bordered by expanded marginal ridge separating it from vertical mantle. Areolae poroid, on valve face arranged in interrupted radial and sub-radial rows extending from off-centre hyaline area from which a stout spine extends. Scattered spinules cover valve face disturbing areolar arrangement. Mantle areolae in vertical rows situated between hyaline marginal ridge and hyaline valve margin. Mantle areolae covered by network of anastomosing costae. Internally areolae sunk in rows between hyaline ribs, areolae becoming more numerous towards valve margin. One (1) rimoportula present, its external opening through stout tube expanded at its summit, internally as slit between raised lips.</p>Published as part of <i>Williams, David M., Sims, Pat A. & Witkowski, Jakub, 2023, Notes on the rare Cretaceous species Syndetocystis uralensis Strelnikova leading to the description of a new monotypic genus Monoportula P.
