A Global Agenda For Advancing Freshwater Biodiversity Research, Alain Maasri, Sonja C. Jähnig, Hendrik Freitag, 93 Co-Authors

Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals and the mobilisation of substantial resources. While the reasons are varied, investments in both research and conservation of freshwater biodiversity lag far behind those in the terrestrial and marine realms. Inspired by a global consultation, we identify 15 pressing priority needs, grouped into five research areas, in an effort to support informed stewardship of freshwater biodiversity. The proposed agenda aims to advance freshwater biodiversity research globally as a critical step in improving coordinated actions towards its sustainable management and conservation.
Classifying Mosquito Presence And Genera Using Median And Interquartile Values From 26-Filter Wingbeat Acoustic Properties, Hernan S. Alar, Proceso L. Fernandez Jr

Mosquitoes are known to be one of the deadliest creatures in the world. There have been several studies that aim to identify mosquito presence and species using various techniques. The most common ones involve automatic identification of mosquito species from the sounds produced by flapping its wings. The development of these important concepts and technologies can help reduce the spread of mosquito-borne diseases. This paper presents a simple model based on mean and interquartile values that aim to solve the mosquito classification. Despite its simplicity, the proposed model significantly outperforms a Convolutional Neural Network (CNN) model in identifying the mosquito …
Serum Biochemical Profile Of Captive-Bred Philippine Crocodiles (Crocodylus Mindorensis Schmidt, 1935) Sub-Adults, Janice A. Ragaza, Stephanie F. Velasquez, Marian Samantha M. Asuncion, Elyssa Marie F. Torres, Rainier Manalo, Hendrik Freitag
Serum Biochemical Profile Of Captive-Bred Philippine Crocodiles (Crocodylus Mindorensis Schmidt, 1935) Sub-Adults, Janice A. Ragaza, Stephanie F. Velasquez, Marian Samantha M. Asuncion, Elyssa Marie F. Torres, Rainier Manalo, Hendrik Freitag

The Philippine crocodiles Crocodylus mindorensis Schmidt; 1935 are a critically endangered species that necessitate minimally invasive diagnostic tools for their physiological state and health assessment. In the current study; we determined the reference ranges for the serum biochemistry of male and female captive-bred C. mindorensis sub-adults. We collected blood samples from the post-occipital venous sinus of six male and seven female captive-bred crocodile sub-adults at the Palawan Wildlife Rescue and Conservation Center and quantified the serum biochemical values for cholesterol; triglycerides; uric acid; glucose; creatinine; aspartate aminotransferase (AST); alanine aminotransferase (ALT); albumin; total protein; and globulin. We defined reference ranges …

The Municipality of Lake Sebu in Mindanao; Philippines offers various opportunities for income-generating fishing activities with its abundant surface water bodies. Lake Sebu is particularly known for good quality tilapia; farmed in fish cages. This study employed primary data collection methods; namely key informant interview; focus group discussion and a comprehensive livelihood household survey to assess the conditions and problems constraining fishing households in Lake Sebu. The study found that fishing-related benefits were mainly derived from aquaculture. Capture fisheries are essentially very small-scale; low gear open fishing done by local fisher folk that generates only subsistence income. Local residents are …

Investigations of type material and new material from the Philippines (Luzon) revealed that Baetis luzonensis Müller-Liebenau, 1982 and B. realonae Müller-Liebenau, 1982 do not belong to Baetis Leach, 1815. A new genus, Philibaetis gen. nov., is described to accommodate both species and both are re-described based on larvae. The new genus is characterised by having a rectangular labrum with a submarginal row of long, simple setae on the dorsal surface and ventrally on lateral margins long, simple, spine-like setae, on anterolateral margins long, feathered setae and medially long, bifid setae and a partial, submarginal row of lanceolate setae. Both mandibles …

Global warming is progressing at a faster speed than has been estimated earlier in climate forecasting, and the ocean responds rather quickly to global temperature increase. This study uses remotely sensed data that were accessed from the System for Multidisciplinary Research and Applications (NASA Giovanni) to study environmental change in the Philippines’ coast. Monthly averaged sea surface temperature series from around the Philippines indicate that the Philippines follow the global trend in ocean temperature increase and show the increase of about 0.50C within two decades. Despite the high variability in temperature, the linear regressions displayed for all seasons show an …
Hydraena (S.Str.) Dinarica, New Species (Coleoptera: Hydraenidae) Along With Further Records Of Hydraena Spp. From Durmitor National Park, Montenegro And Comments On The Dna Barcoding Problem With The Genus, Hendrik Freitag, Rick De Vries, Marta Paterno, Simone Maestri, Massimo Delledonne, Cameron G.

Background Long-palped Water Beetles were collected during a taxon expedition in Montenegro which involved citizen scientists, students and taxonomists. The material was collected from springs, brooks, fens and the Tara River, at altitudes between 600 m and 1450 m above sea level, using fine-meshed hand-nets and by manual checking of submerged substrates. The morphological species delimitation was supplemented and congruent with mtDNA sequences mainly obtained in the field using the newly-developed MinION-based ONTrack pipeline. New information The new species Hydraena dinarica Freitag & de Vries, sp. n. from Durmitor Mt. is described, illustrated and compared in detail to closely-related congeners …

Cymothoid isopod research is relatively scarce in the Philippines, despite the local economic significance of bigeye scad as an inexpensive source of protein and other nutrients. Isopod parasitism has also been shown to have detrimental effects on their fish hosts. The current study aimed to define the host-parasite relationship between cymothoid isopod and bigeye scad by determining cymothoid isopod prevalence, intensity, and host-parasite length correlations in bigeye scad (Selar crumenophthalmus) hosts sourced from Batangas, Philippines. Fish samples were sampled from the Tagaytay City Market in Cavite, which sources fish directly from Batangas. Fish samples were immediately measured and …
