Conservation Biology Guide

A skill for conducting conservation biology research, covering species assessment methods, habitat modeling, population viability analysis, key biodiversity databases, and frameworks for conservation prioritization.

Species Assessment and Red List

IUCN Red List Categories

Extinction Risk Categories (from highest to lowest):

  EX  - Extinct
  EW  - Extinct in the Wild
  CR  - Critically Endangered
  EN  - Endangered
  VU  - Vulnerable
  NT  - Near Threatened
  LC  - Least Concern
  DD  - Data Deficient
  NE  - Not Evaluated

Classification criteria (any one triggers the category):
  A: Population size reduction
  B: Geographic range (extent of occurrence, area of occupancy)
  C: Small population size and decline
  D: Very small or restricted population
  E: Quantitative extinction probability analysis

Querying the IUCN API

import os
import json
import urllib.request


def get_species_assessment(species_name: str) -> dict:
    """
    Retrieve IUCN Red List assessment for a species.

    Args:
        species_name: Scientific name (e.g., 'Panthera tigris')
    """
    api_token = os.environ["IUCN_API_TOKEN"]
    encoded_name = urllib.parse.quote(species_name)
    url = f"https://apiv3.iucnredlist.org/api/v3/species/{encoded_name}?token={api_token}"

    req = urllib.request.Request(url)
    response = urllib.request.urlopen(req)
    data = json.loads(response.read())

    if data.get("result"):
        species = data["result"][0]

Habitat Modeling

Species Distribution Models (SDMs)

Population Viability Analysis (PVA)

Estimating Extinction Risk

PVA simulates population dynamics to estimate extinction probability
over a given time horizon.

Key inputs:
  - Current population size and structure (age/stage)
  - Vital rates: survival, fecundity (with variance)
  - Carrying capacity and density dependence
  - Environmental and demographic stochasticity
  - Catastrophe frequency and severity
  - Genetic factors (inbreeding depression)

Common software:
  - Vortex: Individual-based PVA simulation
  - RAMAS GIS: Spatially explicit PVA
  - R packages: popbio, lefko3, Compadre for matrix models

Outputs:
  - Probability of extinction over T years
  - Expected minimum population size
  - Population growth rate (lambda) and its variance
  - Sensitivity of persistence to management actions

Conservation Prioritization

Frameworks for Decision-Making

Systematic Conservation Planning (Margules & Pressey):
  1. Compile data on biodiversity features and their distributions
  2. Set conservation targets for each feature
  3. Review existing protected area coverage
  4. Select additional areas using optimization (e.g., Marxan, Zonation)
  5. Implement and manage conservation actions
  6. Monitor outcomes and adapt

Key principles:
  - Representativeness: All species/habitats should be represented
  - Complementarity: Each new area should add maximum new coverage
  - Efficiency: Minimize cost while meeting targets
  - Connectivity: Corridors link protected areas

Reporting Conservation Research

Report species names with taxonomic authority and reference to the taxonomic standard used (e.g., ITIS, Catalogue of Life). Deposit occurrence data in GBIF. Follow the Darwin Core standard for biodiversity data. Use IUCN criteria language when discussing threat status. Clearly state conservation implications and management recommendations, as conservation biology is an applied and mission-driven discipline.
