TNC as a Stakeholder Representative for the Environment TNC is a global, nonprofit organization dedicated to conserving the lands and waters on which all life depends. We seek to achieve our mission through science-based planning and implementation of conservation strategies. For decades, we have dedicated resources to establishing diverse partnerships and developing foundational science products for achieving positive outcomes for people and nature in California. TNC was part of a stakeholder group formed by the Water Foundation in early 2014 to develop recommendations for groundwater reform and actively worked to shape and pass SGMA. Our reason for engaging is simple: California’s freshwater biodiversity is highly imperiled. We have lost more than 90 percent of our native wetland and river habitats, leading to precipitous declines in native plants and the populations of animals that call these places home. These natural resources are intricately connected to California’s economy providing direct benefits through industries such as fisheries, timber and hunting, as well as indirect benefits such as clean water supplies. -

Diversity and distribution of the free-living freshwater Cyclopoida (Copepoda: Crustacea) in the Neotropics Silva, WM.* Departamento Ciências do Ambiente, Campus Pantanal, Universidade Federal de Mato Grosso do Sul – UFMS, Av. Rio Branco, 1270, CEP 79304-020, Corumbá, MS, Brazil *e-mail: [email protected] Received March 26, 2008 – Accepted March 26, 2008 – Distributed November 30, 2008 (With 1 figure) Abstract Cyclopoida species from the Neotropics are listed and their distributions are commented. The results showed 148 spe- cies in the Neotropics, where 83 species were recorded in the northern region (above upon Equator) and 110 species in the southern region (below the Equator). Species richness and endemism are related more to the number of specialists than to environmental complexity. New researcher should be made on to the Copepod taxonomy and the and new skills utilized to solve the main questions on the true distributions and Cyclopoida diversity patterns in the Neotropics. Keywords: Cyclopoida diversity, Copepoda, Neotropics, Americas, latitudinal distribution.

Daru) Running head: Phylogenetic regionalization of seagrasses 1 Abstract While our knowledge of species distributions and diversity in the terrestrial biosphere has increased sharply over the last decades, we lack equivalent knowledge of the marine world. Here, we use the phylogenetic tree of seagrasses along with their global distributions and a metric of phylogenetic beta diversity to generate a phylogenetically-based delimitation of marine phytoregions (phyloregions). We then evaluate their evolutionary affinities and explore environmental correlates of phylogenetic turnover between them. We identified 11 phyloregions based on the clustering of phylogenetic beta diversity values. Most phyloregions can be classified as either temperate or tropical, and even geographically disjunct temperate regions can harbor closely related species assemblages. -

THE USE OF THE COPEPOD MESOCYCLOPSLONGISEZUS AS A BIOLOGICAL CONTROL AGENT FOR AEDES AEGYPTI IN CALI, COLOMBIA MARCELA SUAREZ-RUBIOI,z EIIU MARCO E SUAREZ3 ABSTRACT. We present data on the efficacy of Mesocyclops longisetus as a biocontrol agent in controlling Aedes aegypti larvae in catch basins in Cali, Colombia. Additionally, we determined some of the features that facilitated the establishment ofthe copepods in catch basins. Between June 1999 and February 200O,201 catch basins were treated with an average of 500 adult copepods. The copepods had established in 49.2Vo of all the basins and they maintained Ae. aegypti larvae at low densities until the end of the 8-month study. The corrected efficacy percent was 9O.44o. The copepods established in basins located in a flat area as opposed to those in steep areas, exposed to sunlight and with 0-7ovo of floating organic matter. when the catch basins were con- taminated with synthetic washing agents, like detergents, the copepods did not survive.

The Mysteries of Bird Migration – Still Much to Be Learnt
The mysteries of bird migration – still much to be learnt Franz Bairlein ABSTRACT Bird ringing has unveiled many mysteries of avian migrations, notably routes and destinations. However, there is still much to be explored by the use of ringing and other marking techniques. Satellite tracking, geolocation and global positioning systems are new tools, as well as particular chemical and molecular markers which appear to be very useful in the study of bird migration by delineating origin of birds and connectivity between breeding and non-breeding grounds. Understanding of bird migrations also gained much from captive studies about the internal mechanisms in the control of bird migration, but we still lack knowledge about external factors, such as food availability, weather, competitors, parasites or diseases.This paper summarises ongoing studies on Northern Wheatears Oenanthe oenanthe to illustrate the benefit of such an integrated approach. Future migration research must aim much more at comparative research and a more integrated approach at various spatial and temporal scales, and linking various sub-disciplines. It is also important to realise that migration is only one part of the life-cycle of a migrating species.Thus, linking migration and breeding is another future challenge, for both basic science and conservation of migratory birds. or centuries, the seasonal arrival and The study of bird migration by ringing departure of bird species to and from Our knowledge of bird migration improved Ftheir breeding grounds remained a dramatically with the development of bird mystery.

Partial migration in the Mediterranean Storm Petrel Hydrobates pelagicus melitensis. Marine Ornithology 47: 105–113. Studying the migration routes and wintering areas of seabirds is crucial to understanding their ecology and to inform conservation efforts. Here we present results of a tracking study carried out on the little-known Mediterranean Storm Petrel Hydrobates pelagicus melitensis. During the 2016 breeding season, Global Location Sensor (GLS) tags were deployed on birds at the largest Mediterranean colony: the islet of Filfla in the Maltese Archipelago. The devices were retrieved the following season, revealing hitherto unknown movements and wintering areas of this species. Most individuals remained in the Mediterranean throughout the year, with birds shifting westwards or remaining in the central Mediterranean during winter. However, one bird left the Mediterranean through the Strait of Gibraltar and wintered in the North Atlantic. Our results from GLS tracking, which are supported by data from ringed and recovered birds, point toward a system of partial migration with high inter-individual variation. This highlights the importance of trans-boundary marine protection for the conservation of vulnerable seabirds. Key words: Procellariformes, movement, geolocation, wintering, Malta, capture-mark-recovery INTRODUCTION The Mediterranean Storm Petrel has been described as sedentary, because birds are present in their breeding areas throughout the year The Mediterranean Storm Petrel Hydrobates pelagicus melitensis is (Zotier et al. -
CMS/CAF/Inf.4.13 1 Central Asian Flyway Action Plan for Waterbirds and Their Habitat Country Report
CMS/CAF/Inf.4.13 Central Asian Flyway Action Plan for Waterbirds and their Habitat Country Report - INDIA A. Introduction India situated north of the equator covering an area of about 3,287,263 km2 is one of the largest country in the Asian region. With 10 distinctly different bio geographical zones and many different habitat types, the country is known amongst the top 12 mega biodiversity countries. India is known to support 1225 species of bird species, out of these 257 species are water birds. India remains in the core central region of the Central Asian Flyway (CAF) and holds some crucial important wintering population of water bird species. India is also a key breeding area for many other water birds such as Pygmy cormorant and Ruddy-shelduck, globally threatened water birds such as Dalmatian Pelican, Lesser White-fronted Goose, Siberian crane, oriental white stork, greater adjutant stork, white winged wood duck etc. Being located in the core of the CAF, and several important migration routes the country covers a large intra-continental territory between Arctic and Indian Ocean. Being aware of the importance of the wetlands within the geographic boundary of the India for migrating avifauna, India has developed a wetland conservation programme. India currently has 19 RAMSAR sites. India has identified more than 300 sites which has the potential to be consider as the RAMSAR sites. However, being the second most populus nation in the world with agricultural economy, wetlands are one of the most used habitat with water bird and human interface. Much of the Indian landmass also being dependent to the normal monsoonal rainfall for precipitation is also subjected to extremes of drought and flood making the wetlands vulnerable to drastic ecological changes.
