La Selva
Ecology and Natural History of a Neotropical Rain Forest
Edited by Lucinda A. McDade, Kamaljit S. Bawa, Henry A. Hespenheide, and Gary S.
University of Chicago Press, 1994
La Selva, a nature reserve and field station in Costa Rica, is one of
the most intensively studied and best-understood tropical field sites
in the world. For over thirty years, La Selva has been a major focus
of research on rainforest ecology, flora, and fauna. This volume
provides the first comprehensive review of this research, covering La
Selva's geographical history and physical setting, its plant and
animal life, and agricultural development and land use.

Drawing together a wealth of information never before available in a
single volume, La Selva offers a substantive treatment of the
ecology of a rainforest. Part 1 summarizes research on the physical
setting and environment of the rainforest, as well as the history of
the research station. Some chapters in this part focus on climate,
geomorphology, and aquatic systems, while others look at soils,
nutrient acquisition, and cycles of energy.

Part 2 synthesizes what is known about the plant community. It begins
with chapters on vegetation types and plant diversity, and also
explores plant demography, spatial patterns of trees, and the impact
of treefall gaps on forest structure and dynamics. Other chapters
address plant physiological ecology, as well as plant reproductive
systems.

Part 3 covers the animal community, summarizing information on the six
best-known animal taxa of the region: fishes, amphibians, reptiles,
birds, mammals, and butterflies. This part includes an overview of
faunal studies at La Selva and a chapter on animal population biology,
which examines animal demography and abundance, and interactions
between predators and prey. Part 4 addresses interactions between
plants and animals and the effects of these interactions on species
diversity.

Part 5 considers the impact of land use and agricultural development
on La Selva and other areas of Costa Rica. One chapter examines land
colonization and conservation in Sarapiqui, another covers subsistence
and commercial agricultural development in the Atlantic lowlands
region, and a third looks at the forest industry in northeastern Costa
Rica. This part also assesses the role and research priorities of La
Selva.

La Selva provides an introduction to tropical ecology for
students and researchers at La Selva, a major source of comparative
information for biologists working in other tropical areas, and a
valuable resource for conservationists.

Life in the Himalaya
An Ecosystem at Risk
Maharaj K. Pandit
Harvard University Press, 2017

The collision of the Indian and Eurasian plates around fifty million years ago profoundly altered earth’s geography and regional climates. The rise of the Himalaya led to intensification of the monsoon, the birth of massive glaciers and turbulent rivers, and an efflorescence of ecosystems along the most extreme elevational gradient on Earth. When the Ice Age ended, humans became part of this mix, and today nearly one quarter of the world’s population inhabits its river basins, from Afghanistan to Myanmar. Life in the Himalaya examines the region’s geophysical and biological systems and explores the past and future of human sustainability in the mountain’s shadow.

Maharaj Pandit divides the Himalaya’s history into four phases. During the first, the mountain and its ecosystems formed. In the second, humans altered the landscape, beginning with nomadic pastoralism, continuing to commercial deforestation, and culminating in pockets of resistance to forest exploitation. The third phase saw a human population explosion, accompanied by road and dam building and other large-scale infrastructure that degraded ecosystems and caused species extinctions. Pandit outlines a future networking phase which holds the promise of sustainable living within the mountain’s carrying capacity.

Today, the Himalaya is threatened by recurrent natural disasters and is at risk of catastrophic loss of life. If humans are to have a sustainable future there, Pandit argues, they will need to better understand the region’s geological vulnerability, ecological fragility, and sociocultural sensitivity. Life in the Himalaya outlines the mountain’s past in order to map a way forward.

Nature's Services
Societal Dependence On Natural Ecosystems
Edited by Gretchen C. Daily; Foreword by John Peterson Myers and Joshua S. Reichert
Island Press, 1997

Life itself as well as the entire human economy depends on goods and services provided by earth's natural systems. The processes of cleansing, recycling, and renewal, along with goods such as seafood, forage, and timber, are worth many trillions of dollars annually, and nothing could live without them. Yet growing human impacts on the environment are profoundly disrupting the functioning of natural systems and imperiling the delivery of these services.

Nature's Services brings together world-renowned scientists from a variety of disciplines to examine the character and value of ecosystem services, the damage that has been done to them, and the consequent implications for human society. Contributors including Paul R. Ehrlich, Donald Kennedy, Pamela A. Matson, Robert Costanza, Gary Paul Nabhan, Jane Lubchenco, Sandra Postel, and Norman Myers present a detailed synthesis of our current understanding of a suite of ecosystem services and a preliminary assessment of their economic value. Chapters consider:

  • major services including climate regulation, soil fertility, pollination, and pest control
  • philosophical and economic issues of valuation
  • case studies of specific ecosystems and services
  • implication of recent findings and steps that must be taken to address the most pressing concerns
Nature's Services represents one of the first efforts by scientists to provide an overview of the many benefits and services that nature offers to people and the extent to which we are all vitally dependent on those services. The book enhances our understanding of the value of the natural systems that surround us and can play an essential role in encouraging greater efforts to protect the earth's basic life-support systems before it is too late.
