Conservation status, research, and knowledge of seagrass habitats in World Heritage properties
Conservation Science and Practice, Volume 4, Issue 12, December 2022., 2022 This study assesses the relative importance of seagrass habitats toward the values of World Heritage properties and reviews the current knowledge about the conservation status, threats, monitoring, and management of seagrass habitats within WH properties. We highlight the lack of research, monitoring, reporting, and management instrument addressing the

Population response to connectivity restoration of high elevation tropical stream reaches in Hawai'i
Conservation Science and Practice, Volume 4, Issue 12, December 2022., 2022 Abstract Tropical island streams are heavily impacted by water withdrawals to the detriment of native ecosystems. Freshwater fauna in the tropics often exhibit diadromous life‐history strategies, requiring hydrologic connectivity between upstream and nearshore habitats.

Some Factors in the Activation of Crab Movement Receptors [PDF]
, 1963 The activation of movement receptors in Pachygrapsus crassipes is examined. Lengthening and shortening of the elastic strand of the propodite-dactylopodite (PD) organ are respectively the adequate stimuli for movement receptors responding uniquely ...

Limnology and Oceanography, EarlyView.Abstract Microplastics (particles < 5 mm) are pollutants of emerging concern in aquatic ecosystems worldwide. Streams are key sites of microplastic input, retention, and transport, and empirical measurements of microplastic movement in lotic ecosystems are needed to inform global microplastic budgets.

Conservation Science and Practice, Volume 5, Issue 1, January 2023., 2023 Eurasian otter (Lutra lutra) are declining widely across China and remain rare and virtually unstudied in Hong Kong. We intensively sampled spraints in the Mai Po wetlands across two years and through microsatellite genotyping identified seven individuals and a dominance of fish (97%) in their diet based on prey‐remains analysis.

Tracking a killer shrimp: Dikerogammarus villosus invasion dynamics across Europe
Diversity and Distributions, Volume 29, Issue 1, Page 157-172, January 2023., 2023 Abstract Aim Invasive alien species are a growing problem worldwide due to their ecological, economic and human health impacts. The “killer shrimp” Dikerogammarus villosus is a notorious invasive alien amphipod from the Ponto‐Caspian region that has invaded many fresh and brackish waters across Europe.

Macromolecular Materials and Engineering, EarlyView.In soft capsules (SCs), four crucial factors can modify the properties of the shell: the shell formulation, its interaction with the fill material, the SC production and its storage conditions. Gelatin is the most used gelling agent for SCs nowadays, but they have some drawbacks which can be solved including other alternative polymers in the shell ...
