It is a fine article, but as I pointed out to the author, like most everything in nature the situation is much, much more complicated than simply declines of bird species. From our work at Yale Forest, we know that Connecticut bird communities are extremely dynamic, with more that 50% turnover in 35 years and population increases actually outpacing decreases- climate change, habitat change, species moving into new habitats, competition, etc. etc. all appear to play roles. The graph shows Yale Forest population increases vs. decreases for species whose continental populations are (1) increasing, (2) decreasing and (3) stable. We will have an article out soon...</div>

It investigates the external anatomy of males vs. females and adults vs. juveniles, and identifies two previously undescribed plumage states. One of these states (see photo) exhibits prominent y-shaped markings on the breast whereas the other exhibits linear markings. It also documents, based on specimen data, the species' historical distribution.</div>

Bird populations at Yale Forest have increased since 1985, but the amount of
variability among individual study sites has also increased. As the figure shows,
surveys were duplicated each year to gain a perspective of survey variability.</div>

<span style="background-color: white; color: #1c1e21; font-family: Helvetica, Arial, sans-serif; font-size: 14px;">Unlike continental trends, which show that birds have declined by 30%, forest birds in northeastern Connecticut have undergone a 20% increase.

Five late May specimens from Alaska provide evidence for a previously unconfirmed breeding population there, whereas specimens from western New York and Montreal provide evidence for a hypothesized fall migration corridor through the northeastern United States.<o:p></o:p></span></div>

<div style="text-align: justify;">
Three tanks of gas is my self-imposed limit- that point at which my shoulders and mind are tired enough to make continuing on less safe for something as strenuous as chain-sawing. On this day, however, the third tank and four more hours of labor had gotten me to where I needed to be- at the completion of beating back decades of landscape neglect. A profusion of multiflora rose, autumn olive, privet, burning bush, Japanese barberry, bittersweet, amelopsis and other non-native invasives had overrun the borders of the ten-acre Connecticut farm now operated by <a href="http://www.birdconservationresearch.org/" target="_blank"><span style="color: blue;">Bird Conservation Research, Inc.</span></a> as a field station.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
To be sure, such border creep into agricultural land is largely the consequence of seed planting by native birds that disperse the fruits and seeds of exotic plants. However, such creep is not compatible with the goals of production agriculture, and our mission for the past four years has been to maximize wildlife values of landscapes within the constraints of an effectively run agricultural operation. Such borders, although wildlife-planted, are far from having the optimal vegetation composition for these locations.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Now that these borders are cut back (although the gargantuan task of turning the resulting slash into wildlife brush piles remains ahead), we are examining available options for replanting the borders with superior vegetation. The borders will shrink from their present 30-75 foot-wide swaths to a more modest but agriculturally practical 15 foot edge that is punctuated by mature trees. The understory is to be converted from invasive exotics to high wildlife value natives, like our various species of evergreens, hollies, viburnums, dogwoods, shadbushes, cherries, roses and aronias, as well as to non-invasive cultivated plants that are also favored by wildlife.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
It is important to recognize that wildlife values are not confined to those species that breed on the property, but also include those conferred by species that pass through the area- notably migratory birds. Hence, plantings must have value at all seasons. Species that flower early and late, species that have persistent overwintering fruit and species that offer substantial cover, roost sites and nest sites are the types of plants to be selected.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
At present, the field station is home to species that successfully use agricultural landscapes like the American Woodcock (we are presently working on banding our local population). It also serves as a migratory stopover (and possibly incipient nesting population) to such typically Midwestern species as the Vesper Sparrow (territorial males in early spring), Savannah Sparrow and Clay-colored Sparrow (present spring and fall).</div>

The next video in the AP Environmental Science topic <i>The Living World</i> is entitled Evolutionary Ecology. The lesson begins by examining a series of specimens of the possibly extinct Eskimo Curlew. Doing so demonstrates the existence of individual variation that cannot be accounted for by considering age or sex. This individual variation may be acted upon by natural selection to yield evolutionary change. The example of gigantism in the genetically isolated, island-dwelling Nightingale Reed-warbler is used as an example. Other species, like the unrelated Gray Catbird exhibit traits like the reed-warbler, which provides an example of convergent evolution. The video also explores coevolution- the influence of one species on the evolution of another. The video concludes by examining the concepts of r an k selection- alternative ways that reproductive strategies may evolve.<br />

The program concludes discussion of the species-area effect by extending its implications to the study of island biogeography. These issues relate to the larger issue of landscape ecology- considering the geographical scale at which ecological phenomena are studied. It concludes by relating ecology to evolution through discussion of natural selection, mutation, fitness and genetic isolation.

The topic of species diversity is focused upon in this next
episode of a <a href="http://www.artsandacademic.net/video-library.php" target="_blank"><span style="color: blue;">video</span></a> series designed to complement the <a href="http://www.birdconservationresearch.org/educators/powerpoints.php" target="_blank"><span style="color: blue;">AP Environmental Science</span></a>
curriculum. It begins with an exploration
of the scale at which diversity is considered, discussing the concepts of
alpha, beta and gamma diversity. It also
considers the components of diversity- species richness and species evenness. </div>
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
The video then goes on to examine methods of
computing diversity. It evaluates
the uses and pitfalls of diversity characterization, including the loss of
information that occurs by computing diversity indicies.</div>

<o:p></o:p></div>
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
Still another diversity-related issue is the edge
effect. The video examines how diversity
responds to the boundary between habitats and how certain species are edge
specialists. It also notes, however, that
edges can have reduced habitat quality as well as higher rates of predator activity.</div>
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
The video concludes by examining the species-area
effect. It considers the phenomenon of
minimum habitat size and the role of chance in the accumulation of species by
virtue of area.</div>

Food webs are extensions of the concept of trophic levels-
the compartmentalized view of how energy flows through ecoystems from primary
producers to primary, secondary and tertiary consumers. The food web concept clarifies that
individual species can influence energy flow in more than one of these trophic
levels. These and related topics are the
subject of the next video in a lecture series related to the AP Environmental
Science national curriculum. The video
also reviews the concept of trophic efficiency- the percent of energy that is
passed from one trophic level to the next, and compares the productivity of a
variety of ecosystems on planet Earth.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<br />
<div class="MsoNormal">
The focus of the video then shifts to that of biological
diversity. It compares a system with few
species in which some reach great abundance with a system housing many species
in which no one assumes dominance. It
also examines the components of diversity- richness and evenness. The video concludes by considering the
patterns of diversity that may be viewed at large geographic scales. This and other videos in this series are

Solar energy captured during the light-dependent reaction of photosynthesis is the ingredient that powers most ecosystem processes. This energy is passed from trophic level to trophic level, fueling the emergence of virtually all life forms on Earth. Energy is the theme of the next video in the <a href="http://www.artsandacademic.net/" target="_blank"><span style="color: blue;">AP Environmental Scienc</span>e</a> topic of <a href="http://www.artsandacademic.net/video-library.php" target="_blank"><span style="color: blue;">The Living World</span></a>.

<br />
The video begins by exploring climatic relationships among biomes through climatographs. It then moves to a discussion of the light and dark reactions of photosynthesis and how these processes are used in producing living biomass. It next considers the laws of thermodynamics and how these constrain energy flow through ecosystems. Concepts relating to productivity are then reviewed, as is the transfer of energy through trophic levels. The video concludes by following energy from primary producers to consumers to decomposers.Bird Conservation Research, Inc.http://www.blogger.com/profile/06867566022023112814noreply@blogger.com0tag:blogger.com,1999:blog-797768705412563017.post-78042041742686890752016-12-18T17:33:00.001-08:002016-12-18T17:33:44.286-08:00WETLAND BIOMES<table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: right; text-align: center;"><tbody>

The next video in the <a href="http://www.artsandacademic.net/video-library.php" target="_blank"><span style="color: blue;">Living World</span></a>
lecture series of <a href="http://www.artsandacademic.net/" target="_blank"><span style="color: blue;">Arts and Academic Publishing</span></a> (the publishing partner of <a href="http://www.birdconservationresearch.org/" target="_blank"><span style="color: blue;">Bird Conservation Research, Inc.</span></a>) extends its discussion
of terrestrial biomes by considering the effects of altitude on the
occurrence of biomes. Alpine zonation, as it is called, refers to
the appearance of increasingly northern-associated biomes as altitude
increases. The video explores the zonation that occurs
in the southern Appalachian Mountains, from temperate seasonal forest
in the lowlands to boreal forest at the highest elevations. A
version of krummholz vegetation even occurs on the highest peaks. In
the northern Appalachians and Rocky Mountains, alpine tundra can
be found.<br />
<div style="margin-bottom: 0in;">
<br />
</div>
<div style="margin-bottom: 0in;">
A phenomenon related to alpine zonation
is that of relict communities- pockets of plant communities that
occur much further south than they occur at present. These communities may still
occupy land that they inhabited when global climate was
different than it is today. In colder microclimates, such as
those found in southern New England bogs, spruce-larch associations
typical of the far north still occur well south of their present
range. Locally endemic species are often found in
such locations, and their occurrence can be related to re-colonization events that followed the close of the last glacial era.</div>

The examination of subtropical savannah focuses on the
Kissimmee Prairie region of southern Florida, and considers its flora and the
role of animals in sustaining this ecosystem.
It also examines its endemic fauna, including such species as the
Caracara. Exploration of the shrubland
biome centers on the San Gabriel Mountains of southern California. It considers the annual distribution of
rainfall and the role of fire in sustaining this ecosystem. It also considers the oak savannah of
northern California and how this environment relates to these two biomes. The video then crosses the southern
California mountains and examines the high desert ecosystem that develops to the
east in the rain shadow of these mountains.
It highlights the Joshua trees of the wetter portions of this desert,
and also investigates animal species like the Gopher Tortoise and Spadefoot
Toad and the adaptations that they possess for living in this environment.</div>

In its tour through <a href="http://www.birdconservationresearch.org/educators/powerpoints.php" target="_blank"><span style="color: blue;">AP Environmental Science</span></a> topics, the
next installment of the <a href="http://www.artsandacademic.net/video-library.php" target="_blank"><span style="color: blue;">Living World</span></a> video series focuses on three additional
biomes. It begins by examining temperate
grasslands, and explores the physical environmental factors that favor the
development of grassland environments- continental climate, limited rainfall
and wildfires. It also explores the
relationship between perennial grassland vegetation and the animal species it
supports, notably the American Bison, Pronghorn Antelope and Black-tailed
Prairie Dog.</div>
<div class="MsoNormal">

<div class="MsoNormal">
The focus then shifts to rainforest environments, first
temperate rainforests and then tropical.
It compares and contrasts these, illustrating the coniferous nature of
the temperate systems and the vast diversity of broadleaf vegetation that fills
tropical systems. In both environments,
abundant moisture produces trees of great size, although the longevity of
temperate rainforest giants is unsurpassed.
The video concludes by depicting the bird life of both systems,
highlighting in particular the specializations employed by the diverse
avifaunas of tropical rainforest.</div>

The topic of biomes is a major one in the <a href="http://www.artsandacademic.net/video-library.php" target="_blank"><span style="color: blue;">AP Environmental Science</span></a> curriculum. To document the characteristics of the world's major biomes, <a href="http://www.artsandacademic.net/" target="_blank"><span style="color: blue;">Arts and Academic Publishing</span></a> has prepared a series of videos. The first in this series explores the concept of biomes and the roles of climate, topography and edaphic factors in determining the geographic distribution of these major subdivisions of Earth's surface. It then goes on to examine four terrestrial biomes: tundra, boreal forest, temperate seasonal forest and temperate grasslands. For each of these four, the prevailing plant life, limiting factors, climate and animal life are reviewed.</div>

Another of the videos in
the environmental science
series that is available
through our internet
publishing partner, <a href="http://www.artsandacademic.net/" target="_blank"><span style="color: blue;">Arts and Academic Publishing</span></a> is
entitled Species Competition.
It begins by
exploring community assembly:
how it is that
particular physical environments
come to be occupied
by particular
groups of species. It
then examines how species
within such communities
might come into
competition for such resources
as food and living
space.
The video then goes on
to explore ideas about
discrete communities as
opposed to communities
of environmental gradients,
where assemblages
of species gradually pass
from one to another. It
examines in more detail
the types of environmental
gradients that
occur along an ordinary
New England wooded
hillside.
The video goes farther
afield in examination of
niche overlap and instances
of inter– and
intra-specific competition,
looking at examples
not only from New
England but also from
tropical regions.<br />
