ABSTRACT In July 2021, desert rose plants were consistently observed with symptoms of brown spots on the leaves, which coalesced and promoted leaf fall. The causal agent of the disease was unknown. This study aimed to identify the pathogen responsible for the symptoms through morphological and molecular characterisation, as well as pathogenicity tests.

Changes in the Size Distribution of a Freshwater Fish After Lake Outlet Dam Removal: A Pilot Study
ABSTRACT The size structure of populations is crucial for predator–prey dynamics and ecosystem function. Anthropogenic pressures such as habitat alteration may affect the demography of many species. We investigated the size structure of European perch (Perca fluviatilis) populations in lakes before and after dam removal by using the planned removals of

Abstract Ecological succession provides a critical framework to evaluate and predict the effects of successional dynamics within plant communities on ecosystem functions, which has become increasingly relevant in recent years as humans adapt to a world that is progressively shaped by anthropogenic disturbances.

Microbial Communities Drive Methane Fluxes From Floodplain Lakes—A Hydrological Gradient Perspective
This study examined the impact of methanotrophic bacteria (MOB) and methanogenic archaea (mGen) on CH4 emissions from oxbow lakes at various successional stages, analysing their interactions with physicochemical properties of water. The microbial structure, defined by the MOB/mGen ratio, shows emission rates of CH4 specific to each oxbow type.
