The hypothesis suggests for example that marine ecosystem managers who want to help tropical fish should focus on sustaining foundational species in the ecosystem such as corals.
With the ecosystem's foundation shored up the natural tendency among species toward greater positive interactions under stress should allow the fish to weather stress better.

Because the birds and fish in this study tended to rebound from each of these events within a year or two the increased variability of upwelling strength has led not to long-term declines.
Black noted that changes in upwelling strength did not affect just fish and seabirds. In a sense these representative species were just the tips of the iceberg.
#Tropical rabbitfish a threat to Mediterranean sea ecosystemsthe tropical rabbitfish which have devastated algal forests in the eastern Mediterranean sea pose a major threat to the entire Mediterranean basin

The two tropical rabbitfish species were reported first in the eastern Mediterranean in 1927 and 1956

and recorded the feeding rates of rabbitfish and other species. They found it was not necessarily a case of the tropical fish eating more algae than the native fish.
The native temperate fish actually ate adult algae at a greater rate than the tropical rabbitfish.
However the two rabbitfish consumed both young and adult algae whereas native fish only ate adult algae.
So the two rabbitfish can completely denude large areas by working together and having one species that targets adult algae
and another species that removes the youngest algal recruits preventing them from making a forest says Dr Vergã s. This research highlights the need to work out how the interactions between different species will change in a warming ocean.

#A case study of manta rays and lagoonsdouglas Mccauley a new assistant professor in UC Santa barbara's Department of Ecology Evolution and Marine Biology does fieldwork in one of the most isolated places in the world--Palmyra Atoll.
and his colleagues chose to study the ecology of Manta alfredi. Manta rays are classified as vulnerable by the International Union for Conservation of Nature
and are present at this site in surprisingly large numbers. The researchers'findings appear in the journal Marine Biology.
There is very little known scientifically about manta rays said Mccauley. If we want to understand what habitats are important to them
Manta rays are a highly mobile species that can travel across many different parts of the ocean.
Mccauley's team decided to focus on how mantas use Palmyra's lagoons. Lagoons are known to be ecologically important to a variety of mobile species including manta rays sharks turtles and dolphins.
We used high-resolution animal tracking tools to describe in as much detail as we could the ecology of the mantas
and their connection to this particular marine habitat Mccauley explained. Using a novel combination of research tools the scientists examined how the manta rays use lagoons
what particular habitat microfeatures are important and what drivers make the fish come and go from Palmyra's lagoons.
Very heavily used by mobile animals as breeding grounds and as places to feed lagoons are highly sensitive to human disturbance.
Palmyra's lagoons and the mantas that use them are protected. However lagoons elsewhere have been compromised. Fishing boat traffic and habitat degradation all may negatively affect mantas in less remote lagoons.
The big question Mccauley and his team wanted to answer is why manta rays congregate in this particular habitat.
It turns out it was at least partially because of the food. The researchers used stable isotope analysis a chemical assay of a tissue biopsy that provides an integrative view of what the animal ate in previous months.
They matched the chemical signature of the mantas to that of zooplankton collected in the lagoons verifying that this habitat serves as an important feeding ground.
Using mathematical modeling we determined that many of the manta rays we encountered took around 80 percent of their energy from lagoon plankton Mccauley said.
and energy to manta rays highlights the need to motivate management interventions in lagoons. Other tools in the researchers'arsenal were high-resolution tracking
which provided information about how the manta rays used the lagoon habitat over long and short periods of time;
whether the manta rays were staying in this habitat for longer time periods by tracking their comings and goings.
Because we were trying to produce a more complete picture of manta ray ecology we had to use a toolkit that pulled out different fleeting pictures
which tells us more accurately what the manta rays are doing Mccauley said. In trying to produce science that is meaningful and useful for managers Mccauley
Additional detailed information about how manta rays use ocean areas outside of lagoons will also be needed to better manage this at-risk species. Story Source:
Stop killing parrotfish to bring back Caribbean coral reefswith only about one-sixth of the original coral cover left most Caribbean coral reefs may disappear in the next 20 years primarily due to the loss
since 1970 including studies of corals seaweeds grazing sea urchins and fish. The results show that the Caribbean corals have declined by more than 50%since the 1970s.
But according to the authors restoring parrotfish populations and improving other management strategies such as protection from overfishing and excessive coastal pollution could help the reefs recover
and causing coral bleaching the report shows that the loss of parrotfish and sea urchin--the area's two main grazers--has in fact been the key driver of coral decline in the region.
An unidentified disease led to a mass mortality of the sea urchin in 1983 and extreme fishing throughout the 20th century has brought the parrotfish population to the brink of extinction in some regions.
The report also shows that some of the healthiest Caribbean coral reefs are those that harbour vigorous populations of grazing parrotfish.
which have restricted or banned fishing practices that harm parrotfish such as fish traps and spearfishing. Other countries are following suit.
Barbuda is about to ban all catches of parrotfish and grazing sea urchins and set aside one-third of its coastal waters as marine reserves says Ayana Johnson of the Waitt Institute's Blue Halo Initiative which is collaborating with Barbuda in the development of its new management plan.
Reefs where parrotfish are protected not have suffered tragic declines including Jamaica the entire Florida Reef Tract from Miami to Key West and the U s. Virgin islands.
The decline in corals started long before climate change began to affect reefs says Terry Hughes author of the 1994 study that predicted the current problems due to parrotfish removal.
This report confirms that vigorous populations of grazing parrotfish are a common attribute of the healthiest Caribbean coral reefs.
Parrotfish populations are crucial to the very survival of coral reefs but are being destroyed despite their enormous ecological and economic value says Jerker Tamelander head of the UNEP coral reef unit.
and respond to the Caribbean coral reef crisis through joint actions including protecting parrotfish under the Protocol on specially protected areas and wildlife of the Cartagena Convention.
#Ancient Arctic sharks tolerated brackish water 50 million years agosharks were a tolerant bunch some 50 million years ago cruising an Arctic ocean that contained about the same percentage of freshwater as Louisiana
The study indicates the Eocene Arctic sand tiger shark a member of the lamniform group of sharks that includes today's great white thresher
and mako sharks was thriving in the brackish water of the western Arctic ocean back then. In contrast modern sand tiger sharks living today in the Atlantic ocean are very intolerant of low salinity requiring three times the saltiness of the Eocene sharks
in order to survive. This study shows the Arctic ocean was very brackish and had reduced salinity back then said University of Chicago postdoctoral researcher Sora Kim first author on the study.
The ancient sand tiger sharks that lived in the Arctic during the Eocene were very different than sand tiger sharks living in the Atlantic ocean today.
The findings have implications for how today's sharks might fare in a warming Arctic region
Maybe the fossil record can shed some light on how the groups of sharks that are with us today may fare in a warming world.
Because sharks are aquatic the oxygen from the ocean is constantly being exchanged with oxygen in their body water and that's
The team analyzed 30 fossil sand tiger shark teeth exhumed from Banks Island and 19 modern sand tiger shark teeth from specimens caught in Delaware bay bordered by Delaware and New jersey.
The paleo-salinity estimate for the modern sand tiger sharks is consistent with the continental shelf salinity present from Delaware south to Florida and from the coastline to roughly six miles offshore known hunting grounds for modern sand tiger sharks
which have formidable teeth and can reach a length of nearly 10 feet. The Eocene epoch which ran from about 56 to 34 million years ago was marked by wild temperature fluctuations including intense greenhouse periods
The salinity gradient across the Eocene Arctic ocean that provided habitat for the ancient sand tiger sharks also was found to be much larger than the salinity gradient tolerated by modern sand tiger sharks living in the Atlantic ocean said Eberle.
The Eocene lamniform group of sharks had a much broader environmental window than lamniform sharks do today.
Through an analysis of fossil sand tiger shark teeth from the western Arctic ocean this study offers new evidence for a less salty Arctic ocean during an ancient'greenhouse period'says Yusheng Chris Liu program

#Protecting and connecting the Flathead National Forest in Montanaa new report from the Wildlife Conservation Society (WCS) calls for completing the legacy of Wilderness lands on the Flathead National Forest in Montana.
The report identifies important secure habitats and landscape connections for five species--bull trout westslope cutthroat trout grizzly bears wolverines and mountain goats.
Located in northwest Montana adjacent to Glacier national park the 2. 4 million-acre Flathead Forest is a strategic part of the stunning and ecologically diverse Crown of the Continent Ecosystem.
Wildlife and Wild Lands on the Flathead National Forest Montana WCS Senior Scientist Dr. John Weaver notes that these protections may not be enough in the face of looming challenges such as climate change.
Reduced stream flow and warmer stream temperatures will diminish habitat for native westslope cutthroat trout
and bull trout that are adapted well to cold waters --while favoring introduced rainbow trout and brook trout.
Weaver found that the Flathead is a stronghold for these fish and wildlife species that have been vanquished in much of their range further south.
His analysis shows that 90 percent of the Flathead has a very high or high conservation value for at least one of the five focal species. In his recommendations Weaver employs a smart strategy for resiliency that protects
and connects large landscapes that have high topographic and ecological diversity. Such a strategy will provide a range of options for animal movements as conditions change.
In total Weaver recommends 404208 acres of roadless area on the Flathead Forest for Congressional designation as National Wilderness
Vital places with particular concentration of present and future habitat include the Whitefish Range adjacent to Glacier national park and the Swan Range east of Flathead Lake.
and decisions about future management on the Flathead National Forest said Weaver. These spectacular landscapes provide some of the best remaining strongholds for vulnerable fish and wildlife and headwater sources of clean water.
These roadless refugia offer a rare opportunity to complete the legacy of protecting wildlife and wildlands on this crown jewel of the National Forest system for people today and generations yet to come.

#Forest loss starves fish: Forest debris that drains into lakes is important to freshwater food chainsresearch shows forest debris that drains into lakes is an important contributor to freshwater food chains--bolstering fish diets to the extent that increased forest
cover causes fish to get'fat'and sparse forest leaves smaller underfed fish. Debris from forests that washes into freshwater lakes supplements the diets of microscopic zooplankton
and the fish that feed off them--creating larger and stronger fish new research shows.
The researchers warn that as forests are eroded through human activities such as logging the impacts will be felt in aquatic as well as terrestrial food chains.
This enabled scientists to study Yellow perch fish from different parts of a lake that has varying degrees of surrounding forest coverage.
By analysing the young Perch that had been born that year scientists were able to determine that at least 34%of the fish biomass comes from vegetation increasing to 66%in areas surrounded by rich forest.
Essentially the more forest around the edge of the lake the fatter the fish in that part of the lake were.
Scientists say that the young fish in lake areas with scant forest cover were much smaller
The fish then feed on the zooplankton. Until recently algae were believed to be the only source of food for zooplankton
areas with the most zooplankton had the largest'fattest'fish said Tanentzap. Areas of Daisy Lake closest to the nickel smelt-works remain bare--dirt
and rock instead of the once lush forest. The young fish in these parts of the lake were considerably smaller due to less available food.
This leaves them susceptible to poor health and predators as they won't be as strong so less likely to go on to breed and repopulate.
