These human caused problems are endangering the ecological and economic benefits produced by some of Earth's most diverse and productive ecosystems.

Here we investigate the effects of exposure to water-borne atrazine contamination on wild leopard frogs (Rana pipiens) in different regions of the United States and find that 10-92% of males show gonadal abnormalities such as retarded development and hermaphroditism. These results are supported by laboratory observations, which together highlight concerns over the biological effects of environmental atrazine on amphibians http://www.nature.com/cgi-taf/DynaPage.taf?file=/nature/journal/v419/n69 10/abs/419895a_fs.html&filetype=&_UserReference=C0A804EC46519EA7CBB42615 34B93DC13E94 Herbicides: Feminization of male frogs in the wild TYRONE HAYES, KELLY HASTON, MABLE TSUI, ANHTHU HOANG, CATHRYN HAEFFELE & AARON VONK Laboratory for Integrative Studies in Amphibian Biology, Museum of Vertebrate Zoology, and Department of Integrative Biology, University of California, Berkeley, California 94720-3140, USA e-mail: tyrone@socrates.berkeley.edu ------------------------------ Date: Thu, 31 Oct 2002 08:56:56 -0500 From: "Cynthia D.

The proposal got generally good reviews, except that the USDA reviewers were quite sure that protein electrophoresis not DNA was the wave of the future. I realized there was little immediate future in working on the population genetics of biological control in this country.

Stacey, Dr. James Webb at Texas A&M University, Galveston organized a largescale study of that exact question back in the early 1990s. I participated in the study for my Master's thesis. I compared bird use of created Spartina alterniflora salt marshes (anywhere from 3-20 years old) with similar natural marshes. Other parts of the study included vegetation analysis (above and below ground), GIS analysis of fetch, area to perimeter ratio, and other physical characterisits, fish use, and sedimentation. A portion of my results were published in Wetlands (1998). The fisheries data were published just prior to that in a fisheries journal (I don't remember which one). You should be able to get copies of three theses from Texas A&M from this project: mine (Stefani Melvin--birds), Andrea Albertson--vegetation, and Timothy Delaney--GIS. I would be happy to discuss this with you off-list if you would like. You can contact me by email at smelvin@sfwmd.gov.

From historical records I can tell you with 100% certainty that the "home ranges" of the "invasive genotypes" of this species are the alfalfa and clover seed producing regions of France, Spain, and Italy. According to USDA research reports there are no useful specialist biocontrol insects in those regions. The current insect biocontrol collecting expeditions to Turkey and southern Russia are collecting insect genotypes that have never experienced the yellow starthistle genotype that is considered an invasive species.

Unless there is site specific evidence that these barbed wire fences are causing significant mortalities of at risk species, it might be better to concentrate on other aspects of habitat improvement such as range and cover improvement, water developments, and invasive species contro .

Hayes" <dochayes@HRINSTITUTE.ORG> Subject: Re: fence removal I don't take it as being picked on, Jack. It is a very legitimate statement. We, however, are not examining the fence removal as an experimental action... instead, if there is sufficient evidence already out there in support of it, it will be done as a practical remediation action. We are also not trying to force fence removal on anyone. It is a choice being considered by a major rancher in our area. I am also open to counter information that typical barbed wire fencing is beneficial to predators and threatened or endangered species. I do not rule that out (just suspect the balance of info to be the other direction :-) ). Best wishes, Bill William A.

It's called Ecocreto (http://www.ecocreto.com/default2.htm). The Facilities Dept. has already used it in a run-off control application in the form of a retention wall. The rapid run-off is trapped behind a low wall and allowed to percolate through at a rate that eliminates erosion. The only concern I have is the manufacture of the material. Its cured state seems to be fine - what I have not been able to find out is what chemical components go into the manufacturing. It's not cheap and requires installation by trained personnel, but has great potential in replacing conventional concrete. I have some ethical questions about its use if the manufacturing process turns out to be detrimental.

The occasion could mark a watershed event -- literally -- in environmental thinking. Regional and state officials will break ground for a state-of-the-art gateway to the Santa Monica Mountains National Recreation Area, the nation's largest urban park. The big draw will be a poured sample of "environmentally friendly" concrete that will be used to pave parking and walkway areas of the parkland on Mulholland Drive, just off of Topanga Canyon Boulevard. It will be the first large-scale use of the material by a state agency in California, officials say. "This is unbelievable stuff," said Stephanie Landregan, chief landscape architect for the Santa Monica Mountains Conservancy, which owns the new park. "It's just the coolest thing to watch water go right through it." Environmentally friendly concrete may sound like an oxymoron, but environmentalists are going gaga over it, Landregan said. It consists of dun-colored porous pavement that looks like a combination of soil and gravel. The difference is that it stays put--it doesn't "give" like dirt or crunch like gravel. And it looks natural, Landregan said. "If you didn't look too hard, you wouldn't realize that it's artificial." Traditional concrete sheds water that in turn digs gullies or collects in puddles. Porous concrete allows water to percolate into the ground. It recharges ground water, prevents erosion, filters out harmful substances and, if it is used in urban settings, decreases the amount of water that flows uselessly to the ocean in storm sewers, Landregan said. "This represents the merger of green infrastructure with traditional construction," she said. The new 61-acre portal to the vast national recreation area straddling the Santa Monica Mountains has been chosen as a showcase for the new material. "This is the first state-sponsored project in California to do this," Landregan said. Porous concrete will be used to pave the mile-long entry road, a 70-car parking lot and walkways. The new parkland is also important, officials said, because it will provide San Fernando Valley residents with easier access to the recreation area, which is a patchwork of parks stretching from Point Mugu in Ventura County to Griffith Park in Los Angeles. Visitors from north of Mulholland currently have to make a long drive through winding Topanga Canyon to get to the most popular parts of the recreation area. By next summer, the added parkland will allow nature lovers to zip south from the Ventura Freeway on a short stretch of Topanga Canyon Boulevard and be in the wilderness in record time. "If you're not a big hiker or mountain biker, you might not want to go the long route," conservancy spokeswoman Dash Stolarz said. "This is a very easy-to-get-to place." The newly acquired land is surrounded on all sides by trails leading to the heart of the recreation area. When visitors arrive at Mulholland Gateway Park, they'll be greeted by state-of-the-art facilities, including solar-powered lighting, self-composting restrooms and a half-mile interpretive nature trail accessible by wheelchair. The land was purchased with $6 million in state funds from a voter-approved bond measure after years of efforts by activists to prevent residential development, Stolarz said. Among the dignitaries expected to attend today's ceremony are state Resources Secretary Mary Nichols, Rep. Brad Sherman (D-Sherman Oaks), Assemblywoman Fran Pavley (D-Agoura Hills) and Los Angeles City Councilwoman Cindy Miscikowski. * * * Copyright 2002 Los Angeles Times *** NOTICE: In accordance with Title 17 U.S.C.

FOCUS Efforts to understand the mechanisms underlying competition and selection on the gametic/gametophytic level have increased nearly independently for animals and plants. The workshop aims to bring together zoologists and botanists interested in different aspects of reproductive biology, e.g. pollen competition and sperm competition. It provides a forum in which evolutionary biologists, behavioural ecologists, reproductive physiologists and theoreticians can exchange ideas, highlight common ground and explore new directions.

I am a first-year graduate student in the process of designing my thesis project. My broad idea at this point is to compare functions occurring in natural wetlands to those in created wetlands. I also intend on looking at different ages of created wetlands to see at what point (if any) created sites begin to function like natural sites. In searching the literature, I have not been able to find any information on the best way to approach this type of problem. Because created wetlands generally do not resemble natural wetlands in any sense, and they are usually not the same type of wetland as it replaces, how do I go about comparing them? If I focus on landscape setting (ie., natural floodplain vs. created floodplain), I run the risk of comparing very different types of wetlands, even though they are located in the same geomorphic setting (e.g., open water systems vs vegetated systems). Or I could examine functions based on the type of wetland replaced, such as comparing a natural slope wetland to a depressional wetland that was created to replace a slope. In this case, I run the risk of comparing "apples to oranges", as these two types are obviously different. I am hoping someone with some experience with this dilemma could provide some guidance or could recommend literature that may be helpful. Thank you.

Hicks" <DJHicks@MANCHESTER.EDU> Subject: hemispherical photo summary My thanks to those who answered my query about use of a fisheye lens with Nikon Coolpix for canopy analysis: Jerry Howard, David Jenkins, Benjamin Gilbert, Jeff Klemens, Eliza Maher, Peter Weisberg, C.E. Tripler, Spencer Hall, and Mike Kearsley. Several people requested a summary of the replies, so here's my digest of it: 1. All those who replied had successfully used this system, although several camera models are in use. Most input images into Gap Light Analyzer (GLA). 2. Camera stability is an important issue, and a tripod or self-levelling system is necessary. (I have been taking canopy photos with a 35 mm SLR, and use a Bogen video tripod or step ladder to get the camera to the right height. Then I use a hand level and compass to orient it correctly. Using the camera's time-release feature helps to avoid shake problems, and allows the photographer to get out of the image.) 3. There are several variants of both the camera and the lens, and it is essential to purchase an adaptor for some camera-lens combinations. 4. There may be issues with (some? all?) Nikon lenses, since GLA expects a 180 degree image with a certain distortion pattern. The Nikons take a 183 degree image, but this can be fixed by masking or by manipulating the registration of the image when it is entered into GLA. (However, no one seems to have a fix for the distortion issue, nor is it clear if it significantly affects the results.) 5. One person recommended the Coolpix 995, a model which makes setting up the photo simpler when using a tripod. 6. Cameras settings matter, since it is possible to mask off part of the image. ------------------------------ Date: Tue, 29 Oct 2002 12:30:02 -0500 From: Parmeliamm@AOL.COM Subject: Re: How do we study created vs. natural wetlands? Stacey: Look into the HGM approach... Hydrogeomorphic... which was started/"invented by USGS, I think, for the purpose of comparing existing and created wetland . There are folks in the Army Corps of Engineers who are working on databas s and reference wetlands throughout the country in an attempt to make HGM TH assesment methodology for Section 404 (Clean Water Act) permitting. There hold be tons of info out there on it. I also personally know people who have done studies similar to your proposal but have used birds as their indicator of function. Be sure to look through journals like Wetlands, and Restoration Ecology. College of William & Mary p ofessor, Dr. Dan Cristol, has done work on this too. We need studies like you are proposing!

Yes, though it's a bit hard to describe in words. You need to construct a ne series for the error bars. If, for example, you want to show +/- one StdDev use Excel's function to calculate the standard deviations for each bar, and put them into a series parallel to the data. Then use the plus/minus error b r option, setting its range to the StdDev series. I'm working from memory, so I may not have the steps exactly right, but hope ully that will get you started on the right track. Charles Charles W.
