  • How ferns adapted to one of Earth's newest and most extreme environments

    Nature News -- ScienceDaily
    23 Oct 2014 | 11:23 am
    Ferns are believed to be 'old' plant species -- some of them lived alongside the dinosaurs, over 200 million years ago. However, a group of Andean ferns evolved much more recently: their completely new form and structure (morphology) arose and diversified within the last 2 million years. This novel morphology seems to have been advantageous when colonising the extreme environment of the high Andes.

    Have you ever felt awkward? Like you just didn’t fit in with the group? You’re not alone. There are certain species of animals that seem like oddballs compared to the rest of the family. For example, the giant panda is the only bear that subsists solely on plants. The stalk-eyed fly has eyes spaced impossibly far apart. Many lizards eat ants, but the minute leaf chameleon isn’t much bigger than one. In the images below, we reimagine these unlikely creatures as students in a school of “normal” animals. In reality, these animal oddballs are exquisitely adapted to…

  • Retaining forests where raptors nest can help to protect biodiversity

    Raptors can affect the distribution of other species and they can also be used to find forests with high biodiversity value, researchers say. Predators influence decisions on conservation actions because they awake a remarkable interest in the society. However, favoring just predators in conservation can also mislead the scarce funding invested in nature conservation.
  • Mature forests store nitrogen in soil: May help protect waterways from excess nitrogen from industry

    23 Oct 2014 | 6:20 am
    Ecologists working in central Pennsylvania forests have found that forest top soils capture and stabilize the powerful fertilizer nitrogen quickly, within days, but release it slowly, over years to decades. The discrepancy in rates means that nitrogen can build up in soils. Forests may be providing an unappreciated service by storing excess nitrogen emitted by modern agriculture, industry, and transport before it can cause problems for our waterways.

In some instances, development on private land would not align with existing transmission corridors.

    Not only does Otisfield Maine have Little Pond, which is the place where I spend most of my photographic time in Maine, but the Crooked River also traverses the town.  At just about a mile down the road, it's a fairly short trip from our typical base of operations there.  This past July, I spent my last few hours wading in the river, which eventually empties into Sebago Lake.  This river even supports a population of the landlocked salmon.After tromping around here for a few hours, including the undergrowth along the edges, I jumped in a car and headed to the airport.

    Let me stress that it's just not early, it's REALLY early.  Sunrise in June occurs as early as 4:58 a.m. To get up to capture the pre-sunrise light, I had to set an alarm for 4:30.  That's pretty darn early for a vacation, but I did wake one morning that early.  Unfortunately, it was cloudy, and the light was flat and gray.  After looking through all my photographs I have taken at Little Pond, I noticed a gaping hole- I had hardly any photos taken in the morning on the pond.  I remedied that with this photo, one of my favorites from this summer.

Greater and Lesser Yellow-headed Vultures are so similar that for a long time were thought to be the same species. The fact that one, the Lesser Yellow-headed Vulture, acted so differently and favored a different habitat alerted ornithologists to look closer and determine that indeed they were two separate species Seeing a Lesser Yellow-headed Vulture (LYHV) forage on the grassy open floodplains of Amazonian Rivers is like seeing a Harrier in action.

Most rare birds here are only found in specialised places, but you can always rely on our cuckoos to be potentially anywhere, even if your actual chances of seeing one are vanishingly small. It’s a foolish idea to go out and actually try and find them, better to just be ready to possibly see them at any time, while knowing you probably won’t. That said, it was just such a silly impulse that took me last…

    Restoring The Landscape With Native Plants

  • Beneficial Insect Profile - Lacewings

    Brown lacewing larvaAs the last remaining leaves fall from the trees, I start to think about all the beneficial insects that are seeking shelter under the leaf litter or attached to plant stems for the winter. With leaf blowers dominating the suburban landscape, many gardeners are perhaps not aware that they are eliminating next season's predators and parasitoids when they clean-up their garden in the fall. Eggs, larvae, pupae and adults of beneficial insects are blown or raked up, bagged with the leaves and set out at the curb.In perennial gardens we don't need to be this fastidious. Leaves,…

This spring, I found several aggregations of nests on south-facing slopes at a local park.Females began excavating nests as early as the third week of April (unseasonably cool spring). Other nests not on the exposed slopes were easy to find due to the prairie burn performed the previous fall. Ant nests clustered around the clumps of little bluestem grass, Schizachyrium scoparium in this prairie were dug/sought out by northern flickers in early April. The flickers did not show any…

    Cuckoo Bees ~ Coelioxys spp.A female cuckoo bee, Coelioxys sp. nectars onhairy false goldenaster, Heterotheca villosa in late fallThere are many types of cuckoo bees in North America. In the Coelioxys genus, there are approximately 46 speces. The common name "cuckoo bee" is typically used for any bee species that lays its eggs in the nests of other bees. These bees are known as cleptoparasites, where the cuckoo bee larvae kill the host larvae and feed on the provisions (pollen and nectar) provided by the host bee.Coelioxys cuckoo bees are common in the summer months; in central Minnesota I…

  • Predator Profile ~ Grass Carrying Wasps, Isodontia spp.

    12 Dec 2013 | 8:15 am
    Grass-Carrying Wasps ~ Isodontia spp. There are a number of ways to attract beneficial insects to your landscape. Planting a diversity of native plants is an easy, win-win solution. Not only do the plants attract many types of beneficial insects including solitary wasps, but they help support a functioning, complex ecosystem.One of the most interesting solitary wasps in my landscape is the grass carrying wasp. Several years ago I purchased a bell-shaped wire frame. I filled the openings with hollow stems from native perennials in my yard to see what types of solitary bees would use…

    20 Oct 2014 | 5:42 am
    As most of my followers know by now, I have a cabin near the Ouachita National Forest and I am spending all my time at this place. It will take me a long time to explore this area and it has been amazing so far. One of the first amazing things I have encountered is that all I hear are the sounds of wildlife like the Katydids. I will be a little slow at updating this blog and responding to emails for a little while longer. I have plans to get internet at my cabin but I can’t quit exploring long enough to get it setup.

    2 Oct 2014 | 1:36 am
    I am seeing lots of acorns and persimmons this year in Arkansas. I have an acorn tree in my yard that has produced acorns for the first time. As I hike through the forest, I am seeing acorns on the ground and I am hearing them falling. The persimmons seem to also be doing good. The wildlife should be enjoying this. A Few Acorns A couple of Persimmons Wildlife which eat acorns as an important part of their diets include birds, such as jays, pigeons, some ducks, and several species of woodpeckers. Small mammals that feed on acorns include mice, squirrels and several other rodents. Large mammals…
  • Lots Of Walking Stick Insects

    Steve Creek
    1 Oct 2014 | 7:47 am
    I have been seeing lots of Walking Sticks around my new place here in Arkansas and they are very large. I didn’t realize that they are considered injurious to forest and shade trees until I started researching them. The walking stick is a significant problem in parks and recreation sites where it consumes the foliage of oaks and other hardwoods. Severe outbreaks of the walkingstick, Diapheromera femorata, have occurred in the Ouachita Mountains of Arkansas and Oklahoma. The insects eat the entire leaf blade. In the event of heavy outbreaks, entire stands of trees can be completely…
  • Arkansas Quartz Crystals

    30 Sep 2014 | 3:23 am
    The area of the Ouachita National Forest that I have been exploring is known for having the best quality quartz in the world. These crystals of the Ouachita were believed to have sacred and spiritual significance. In 1967, the General Assembly adopted the quartz crystal as the Arkansas State Mineral. (Arkansas) The Ouachita National Forest is also open to miners who have permission from the Forest Service to mine commercially using hand tools, as well as “rockhounds” who pick up small amounts of quartz from the surface of the land for personal use. Approximately 5,000 people visit this…
  • One Eyed Green Heron Catching Fish

    23 Sep 2014 | 3:04 am
    I was walking the shores of North Fork Lake in the Ouachita National Forest here in Arkansas when I spotted this Green Heron catching fish. The Heron was so well hidden that I was close to it before I saw it. I was surprise that it allowed me to get that close until I noticed that it had a bad eye and couldn’t see me. It didn’t seem to be having any problems catching fish and it caught several while I photographed it.

    One of Scotland’s most elusive and endangered breeding birds has had its best breeding season for at least 45 years. The corncrake winters in Africa but breeds in Scotland, hidden in tall vegetation where they can safely raise their chicks. They are so well hidden that a recent RSPB survey counted them not by sight, […]

    What Do Quality Parks Master Naturalists Do?

  • Connetquot State Park - Fish Hatchery - Reopens

    23 Oct 2014 | 1:54 pm

  • Observations On Upland Plant Associations in the Pine Barrens of Long Island

    13 Oct 2014 | 5:14 am
    I published this article in 1995, after being subjected to repeated bullying tactics. Looking back, I am now extremely appreciative of the person who allowed me to publish my observations. The Long Island Botanical Society was open, but the NY Heritage Program pigeonholed the location of my observations to be "roadside edge," of no value. But the controversy is still in play. Are we to be a part of, or apart from, Nature? In the quantum world, we can say - - we are both. In a sustainable word, we must be both.
  • The Tranquility of Water (Carmans River)

    6 Oct 2014 | 1:45 pm
    Written by Pamela Wolf (Oct, 2013) as part of her training to become a Quality Parks Master Naturalist for Session III - Freshwater Wetlands & ConservationFor some reason I am always drawn to water.  All water is good, lakes and the ocean are calming; though I do admit a particular fondness for moving water, rivers, rapids, the shoreline. They all brighten my mood.  I spent a part of last weekend the headwaters of the Carman's River in Southaven Park on the water at the Wertheim Wildlife Refuge.  As much as I could comment on the invasive plant species, water striders,…

  • Lincoln’s Sparrow

    Lauren Shaffer
    16 Oct 2014 | 6:43 pm
    Lincoln’s sparrows are always a treat to see in fall migration in Pennsylvania.  Their finely streaked sides and breast, along with their buffy malar stripe and upper breast, an eye ring, and white throat and belly all combine to make for one handsome bird. s This fall I discovered some wonderful habitat for migrating sparrows and warblers.  At the bottom of a private lane of a neighbor, where field, prairie (shrubby grassland), and deep woods converge; dozens, if not hundreds of mostly sparrows are often found in the grasses, multiflora rose, and autumn olive. Towhees, Mockingbirds,…
  • Great Blue Heron Juvenile

    Lauren Shaffer
    8 Oct 2014 | 11:24 am
    All About Birds states: Whether poised at a river bend or cruising the coastline with slow, deep wingbeats, the Great Blue Heron is a majestic sight. This stately heron with its subtle blue-gray plumage often stands motionless as it scans for prey or wades belly deep with long, deliberate steps. They may move slowly, but Great Blue Herons can strike like lightning to grab a fish or snap up a gopher. In flight, look for this widespread heron’s tucked-in neck and long legs trailing out behind. Juvenile Great Blue Herons are medium-gray like the adult, but have two-toned bills and a streaked…
  • Great Egret, Bathing Beauty

    Lauren Shaffer
    29 Sep 2014 | 6:41 pm
    All birds bathe in order to maintain their plumage, but when a Great Egret takes a bath, it makes a big splash!  While kayaking this week at Montour Preserve, I noticed a Great Egret at the far end of the lake.  Keeping the sun behind me, I paddled up to a respectable distance from the bird and let the boat slowly drift towards the shore.  He deftly plucked one small fish after another from the shallows, and after downing at least 8 fish, he began to bathe. Down went his head and up went the waves of water! Vigorously he submerged himself and raised his wings till the water rolled off his…
  • Olive-sided Flycatcher

    Lauren Shaffer
    29 Aug 2014 | 9:54 am
    The Olive-sided Flycatcher is a very conspicuous bird when it makes its appearance during migration, choosing the top of a snag, or in this case, a telephone pole wire on which to perch.  Except for the Great Crested Flycatcher it’s the largest flycatcher in our region, and is identified by its dark vest, white throat, large thick bill, and sometimes-visible white spots on either side of the rump. These white tufts stood out to me as I slowly drove down the road looking for warblers.  There is only one bird like that!  I quickly pulled over and watched it catch its breakfast for…
  • Great Egret

    Lauren Shaffer
    21 Aug 2014 | 10:47 am
    Great Egrets are huge, elegant birds that frequent wetlands and shores of the river and lakes in summer.  They are not often seen in our area of North Central PA, but one was visiting a friend’s wetlands and I was able to put in with the kayak and get close shots of this awesome bird!  Like other herons and egrets, they will watch for fish or frogs in the water and like lightning, spear them through or grab them with their dagger-like beak. This Great Egret may look silly way up high on top of the tree where he is perched, but actually, Great Egrets will nest as high as 100 feet up in…

They break into capillaries in the dorsal body wall. b) It gives dorso-intestinals to the alimentary canal all along its length. c) In the…
  • HIRUDINARIA-EXCRETORY SYSTEM-NEPHRIDIUM STRUCTURE FUNCTION

    1 Oct 2014 | 4:44 pm
     In HIRUDINARIA the excretory system includes 17 pairs of Nephridia. They are arranged in 6th to 22nd segments, one pair in each segment. In these 17 pairs the first six pairs will not show contact with testis. They are called pre-testicular nephridia. The next 11 pairs of nephridia will show contact with testis, hence they are called testicular nephridia. Structure of Testicular Nephridium: Each nephridium contains six regions. 1) Main lobe 2) Vesicle 3) Apical lobe 4) Inner lobe 5) Initial lobe 6) Ciliated organ.   1) Main lobe: It is the bigger part of the nephridium.
