Autor: Jan‐Claas Dajka, Josie Antonucci diCarvalho, Alexey Ryabov, Gregor Scheiffarth, Lena Rönn, Rob Dekker, Kimberley Peters, Bo Leberecht, Helmut Hillebrand

Publikováno v: Conservation Science and Practice, Vol 4, Iss 10, Pp n/a-n/a (2022)

Abstract The current policy and goals aimed to conserve biodiversity and manage biodiversity change are often formulated at the global scale. At smaller scales however, biodiversity change is more nuanced leading to a plethora of trends in different

Academic Engagement with Wadden Sea Stakeholders: A Review of Past Foci and Possible Futures

Autor: Gabriel I. Gadsden, Kimberley Peters, Jan-Claas Dajka

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

The Wadden Sea became a UNESCO World Heritage Site in 2009 owing to its geographical and ecological importance. Given its status and its global recognition, academic understanding of, and engagement with, a diverse set of stakeholders is crucial to t

Red and green loops help uncover missing feedbacks in a coral reef social–ecological system

Autor: Jan‐Claas Dajka, Anna J. Woodhead, Albert V. Norström, Nicholas A. J. Graham, Maraja Riechers, Magnus Nyström

Publikováno v: People and Nature, Vol 2, Iss 3, Pp 608-618 (2020)

Abstract Social–ecological systems (SES) exhibit complex cause‐and‐effect relationships. Capturing, interpreting, and responding to signals that indicate changes in ecosystems is key for sustainable management in SES. Breaks in this signal–re

Weakening macroalgal feedbacks through shading on degraded coral reefs

Autor: Nicholas A. J. Graham, Victoria Beasley, Gilberte Gendron, Jan-Claas Dajka, Jos Barlow

Publikováno v: EPIC3Aquatic Conservation: Marine and Freshwater Ecosystems, 31(7), pp. 1660-1669, ISSN: 1052-7613

Extensive and dense macroalgal fields can compromise the ecosystem function of habitat mosaics on reefs owing to their limiting effect on patch connectivity. Macroalgae can maintain and increase their dominance with effective self-reinforcing feedbac

Temporal declines in Wadden Sea phytoplankton cell volumes observed within and across species

Autor: Helmut Hillebrand, Josie Antonucci Di Carvalho, Jan‐Claas Dajka, Claus‐Dieter Dürselen, Onur Kerimoglu, Lucie Kuczynski, Lena Rönn, Alexey Ryabov

Cell size is a master trait in the functional ecology of phytoplankton correlating with numerous morphological, physiological, and life‐cycle characteristics of species that constrain their nutrient use, growth, and edibility. In contrast to well�

Uncovering drivers of juvenile coral density following mass bleaching

Autor: Alasdair Harris, James P. W. Robinson, Nicholas A. J. Graham, Karen M. Chong-Seng, Shaun K. Wilson, Jan-Claas Dajka

Publikováno v: Coral Reefs. 38:637-649

Thermally induced mass coral bleaching is globally responsible for major losses of coral cover. Coral recovery from mass coral disturbances like the 2016 bleaching event hinges on successful recruitment of new coral colonies to the existing populatio

How a water-resources crisis highlights social-ecological disconnects

Autor: Jack R Hemingway, Joshua R. Gittins, Jan-Claas Dajka

The sustainable management of water resources is required to avoid water scarcity becoming widespread. This article explores the potential application of a social-ecological framework, used predominantly in the fields of ecology and conservation, as

Investigating sea urchin densities critical to macroalgal control on degraded coral reefs

Autor: Nicholas A. J. Graham, Victoria Beasley, Jan-Claas Dajka, Gilberte Gendron

SummaryThere is an assumption that tropical sea urchins are macroalgal grazers with the ability to control macroalgal expansion on degraded coral reefs. We surveyed abundances ofEchinothrix calamaris, an urchin species common in the western Indian Oc
