A Best Practices Case Study for Scientific Collaboration between Researchers and Managers.

Effective engagement among scientists, government agency staff, and policymakers is necessary for solving fisheries challenges, but remains challenging for a variety of reasons. We present seven practices learned from a collaborative project focused on invasive species in the Great Lakes region (USA-CAN). These practices were based on a researcher-manager model composed of a research team, a management advisory board, and a bridging organization. We suggest this type of system functions well when (1) the management advisory board is provided compelling rationale for engagement; (2) the process uses key individuals as communicators; (3) the research team thoughtfully selects organizations and individuals involved; (4) the funding entity provides logistical support and allows for (5) a flexible structure that prioritizes management needs; (6) a bridging organization sustains communication between in-person meetings; and (7) the project team determines and enacts a project endpoint. We predict these approaches apply equally effectively to other challenges at the research-management-policy interface, including reductions of water pollution, transitions to renewable energy, increasing food security, and addressing climate change.

Breve descripción de Taxorchis schistocotyle Beddard, 1914 (Trematoda, cladorchiidae) por microscopia electrónica de barrido / Short description of Taxorchis schistocotyle Beddard, 1914 (Trematoda, cladorchiidae) with scanning electron microscope

The study describes some morphological trait of Taxorchis schistocotyle Beddard, 1914 (Trematoda, Cladorcniidae) using scanning electron microscope (SEM). Specimens were removed from small instestine during necropsy of Hydrochoeris hydrochaeris (Rodentia, Hydrocheoridae). Samples were fixed in glutaraldehid 3 percent in sodium monoacid phosphate buffer with dehidratation in acetones of increasing graduation. Diagnosis technique used was useful to survey and differentiation among species that parasite Argentinean wild mammalians.

Infección por coccidios en carnívoros silvestres de cautiverio de Argentina / Coccidian infection in captive wild carnivores from Argentina

With the objective to determine the infection frequency by coccidia protozoa, 159 fecal samples from captive wiid camivores were analyzed. A 10.7 percent of the animal analyzed were positive to the infection. Whereas the family Procyonidae has a high percentage of positivity (35 percent), Canidae have lower infection ratio (23-33 percent) and Felidae only 0.3 percent). Family Musteldiae show negative findings

Frecuencia de infección por diphyllobothrium sp cestoda diphyllobothriidae en carnívoros silvestres de Argentina / Diphyllobothrium sp cestoda diphyllobothriidae infection frequency in Argentina wild carnivores

With the aims to determine the infection frequency by tapeworms of Diphyllobothrium genus 30 samples from captive wild carnivores were analyzed. A 30 percent of the animal analyzed was positive to the infection. Whereas the family Procionidae has a high percentage of positivity (60 percent). Canidae have lower infection ratio (20-25 percent). The accuracy for the diagnosis of Diphylobothrium was made by the morphology of scolex, proglottids and eggs. This is the first report of the parasite presence in Argentine wild carnivores
