Understanding Plant Parasitism: Hydnora Africana and European Scientific Practice in the Early Nineteenth Century**

Berichte zur Wissenschaftsgeschichte, EarlyView.
This article will analyze the uncertainties around collecting and classifying Hydnora africana in the first half of the nineteenth century. Emerging from the distinctive dryland ecologies of South Africa, Hydnora was interpreted as strange and cryptic by Europeans primarily because it is a root parasite—a complex floral trait that was little understood.

Ecosystem size predicts social-ecological dynamics

Ecology and Society, 2019
Recreational fisheries are complex adaptive systems that are inherently difficult to manage because of heterogeneous user groups (consumptive vs. nonconsumptive) that use patchily distributed resources on the landscape (lakes, rivers, coastlines). There

Estimating Global Catches of Marine Recreational Fisheries

Frontiers in Marine Science, 2020
Commercial fisheries catches by country are documented since 1950 by the Food and Agriculture Organization (FAO). Unfortunately, this does not hold for marine recreational catches, of which only few, if any, estimates are reported to FAO.

Between and Within Bay Differences in Mesozooplankton Assemblages in the Central and Eastern Baltic Sea: An Exploratory Study

Biological Diversity, EarlyView.
Mesozooplankton assemblages differed significantly both between and within Baltic Sea bays, driven mainly by local salinity and temperature gradients. Distinct communities occurred over distances of less than 1 km, demonstrating strong fine‐scale spatial variability.

Review of the fauna associated with wild and farmed mussels and oysters in the Mediterranean

Biological Reviews, EarlyView.
ABSTRACT Mussels and oysters are important ecosystem engineers which modify the physical and chemical characteristics of the environment and create habitats that support highly diverse associated communities. In the Mediterranean Sea, the native Mediterranean mussel Mytilus galloprovincialis and the European flat oyster Ostrea edulis, together the ...

A methodology for simulating the US recreational fishery for billfish [PDF]

1991 Winter Simulation Conference Proceedings., 2002
A simulation model of the process for recreational tournament fishing for billfish is developed, using the northeastern Gulf of Mexico as the study area. The objective is to explore the relationship between catch-rate and abundance. Starting with an initial fish population, both the boat and fish move throughout a spatial grid as the fishing day ...
