Abstract

Babesiosis is a widely distributed, tickborne, zoonotic, parasitic disease caused by different species of the apicomplexan genus Babesia and occasionally involving human infections (1). In its vertebrate host, the parasite [...]

Abstract

Marine protected areas (MPAs) are widely used for ocean conservation, yet the relative impacts of various types of MPAs are poorly understood. We estimated impacts on fish biomass from no-take and multiple-use (fished) MPAs, employing a rigorous matched counterfactual design with a global dataset of >14,000 surveys in and around 216 MPAs. Both no-take and multiple-use MPAs generated positive conservation outcomes relative to no protection (58.2% and 12.6% fish biomass increases, respectively), with smaller estimated differences between the two MPA types when controlling for additional confounding factors (8.3% increase). Relative performance depended on context and management: no-take MPAs performed better in areas of high human pressure but similar to multiple-use in remote locations. Multiple-use MPA performance was low in high-pressure areas but improved significantly with better management, producing similar outcomes to no-take MPAs when adequately staffed and appropriate use regulations were applied. For priority conservation areas where no-take restrictions are not possible or ethical, our findings show that a portfolio of well-designed and well-managed multiple-use MPAs represents a viable and potentially equitable pathway to advance local and global conservation.

33. Noun phrases in early Germanic languages

Abstract

On the premise that syntactic variation is constrained by factors that may not always be immediately obvious, this volume explores various perspectives on the nominal syntax in the early Germanic languages and the syntactic diversity they display. The fact that these languages are relatively well attested and documented allows for individual cases studies as well as comparative studies. Due to their well-observable common ancestry at the time of their earliest attestations, they moreover permit close-up comparative investigations into closely related languages. Besides the purely empirical aspects, the volume also explores the methodological side of diagnosing, classifying and documenting the details of syntactic diversity. The volume starts with a description by Alexander Pfaff and Gerlof Bouma of the principles underlying the Noun Phrases in Early Germanic Languages (NPEGL) database, before Alexander Pfaff presents the Patternization method for measuring syntactic diversity. Kristin Bech, Hannah Booth, Kersti Börjars, Tine Breban, Svetlana Petrova, and George Walkden carry out a pilot study of noun phrase variation in Old English, Old High German, Old Icelandic, and Old Saxon. Kristin Bech then considers the development of Old English noun phrases with quantifiers meaning ‘many’. Alexandra Rehn’s study is concerned with the inflection of stacked adjectives in Old High German and Alemannic. Old High German is also the topic of Svetlana Petrova’s study, which looks at inflectional patterns of attributive adjectives. With Hannah Booth’s contribution we move to Old Icelandic and the use of the proprial article as a topic management device. Juliane Tiemann investigates adjective position in Old Norwegian. Alexander Pfaff and George Walkden then take a broader view of adjectival articles in early Germanic, before Alexander Pfaff rounds off the volume with a study of a peculiar class of adjectives, the so-called positional predicates, which occur across the early Germanic languages.

41. Observation and restriction of Aculops lycopersicidispersal in tomato layer cultivation

Author

Pfaff, Alexander, Gabriel, Doreen, and Böckmann, Elias

Abstract

The tomato russet mite Aculops lycopersicihas become a challenging pest in tomato production in the EU. The number of available acaricides is low, and the efficacy of biological control is limited. With this study, we aim to understand better the unhindered dispersal dynamics and develop a method to reduce dispersal on plants.
